Monitor closely
Concomitant administration of corticosteroids may potentiate the risk of tendinitis and tendon rupture associated with fluoroquinolone treatment. The mechanism is unknown. Tendinitis and tendon rupture have most frequently involved the Achilles tendon, although cases involving the rotator cuff (the shoulder), the hand, the biceps, and the thumb have also been reported. Some have required surgical repair or resulted in prolonged disability. Tendon rupture can occur during or up to several months after completion of fluoroquinolone therapy.
Management
Caution is recommended if fluoroquinolones are prescribed in combination with corticosteroids, particularly in patients with other concomitant risk factors (e.g., age over 60 years; recipient of kidney, heart, and/or lung transplant). Patients should be advised to stop taking the fluoroquinolone, avoid exercise and use of the affected area, and promptly contact their physician if they experience pain, swelling, or inflammation of a tendon. In general, fluoroquinolones should only be used to treat conditions that are proven or strongly suspected to be caused by bacteria and only if the benefits outweigh the risks.

Food/lifestyle interactions
Moderate food/lifestyle interactions
Moderate:
dexAMETHasone Food/Lifestyle
Applies to: Primethasone (dexamethasone)
Monitor
Concomitant use of systemic corticosteroids (e.g., prednisolone) with alcohol or products containing alcohol may increase gastrointestinal irritation and the risk of ulceration and bleeding. The proposed mechanism has not been fully elucidated but may involve additive mucosal irritation.
Monitor
Coadministration with grapefruit or grapefruit juice may increase the plasma concentrations of systemic corticosteroids. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruit. In general, the effect of grapefruit juice is concentration-, dose- and preparation-dependent, and can vary widely among brands. Certain preparations of grapefruit juice (e.g., high dose, double strength) have sometimes demonstrated potent inhibition of CYP450 3A4, while other preparations (e.g., low dose, single strength) have typically demonstrated moderate inhibition. Pharmacokinetic interactions involving grapefruit juice are also subject to a high degree of interpatient variability, thus the extent to which a given patient may be affected is difficult to predict.
Management
Caution is advised if corticosteroids and alcohol are used together, especially in patients with a prior history of peptic ulcer disease or gastrointestinal bleeding. Patients should be advised to report signs and symptoms of gastrointestinal ulceration and/or bleeding such as severe abdominal pain, dizziness, lightheadedness, and the appearance of black, tarry stools. Patients who regularly consume grapefruit or grapefruit juice should be monitored for adverse effects and for changes in corticosteroid plasma concentrations.

Disease interactions
56 potential interactions Applies to: 52 conditions, including High Blood Pressure, High Cholesterol, Depression, Underactive Thyroid, and Heart Failure.
Abnormal Glucose Tolerance
Moderate:
Primethasone
The dexAMETHasone in Primethasone has a moderate potential interaction with Abnormal Glucose Tolerance.
Corticosteroids can raise blood glucose level by antagonizing the action and suppressing the secretion of insulin, which results in inhibition of peripheral glucose uptake and increased gluconeogenesis. Therapy with corticosteroids should be administered cautiously in patients with diabetes mellitus, glucose intolerance, or a predisposition to hyperglycemia. Patients with diabetes mellitus should be monitored more closely during corticosteroid therapy, and their antidiabetic regimen adjusted accordingly.
Adrenal Tumor
Moderate:
Primethasone
The dexAMETHasone in Primethasone has a moderate potential interaction with Adrenal Tumor.
Corticosteroids mimic the effects of endogenous cortisol and aldosterone. Use of these agents may aggravate conditions of hyperadrenocorticalism in a dose-dependent manner.
Aortic Aneurysm
Moderate:
delafloxacin
Delafloxacin has a moderate potential interaction with Aortic Aneurysm.
The use of certain fluoroquinolones may increase the risk of aortic aneurysm and dissection. It is recommended to reserve the use of delafloxacin only when there are no alternative antibacterial treatments available in patients with a known aortic aneurysm or patients who are at higher risk for aortic aneurysms.
Cataract
Moderate:
Primethasone
The dexAMETHasone in Primethasone has a moderate potential interaction with Cataract.
Prolonged use of corticosteroids may cause posterior subcapsular cataracts and elevated intraocular pressure, the latter of which may lead to glaucoma and/or damage to the optic nerves. Long-term therapy with corticosteroids should be administered cautiously in patients with a history of cataracts, glaucoma, or increased intraocular pressure.
Central Nervous System Disorders
Major:
delafloxacin
Delafloxacin has a major potential interaction with Central Nervous System Disorders.
Quinolones may cause CNS stimulation manifested as tremors, agitation, restlessness, anxiety, confusion, hallucinations, paranoia, insomnia, toxic psychosis, and/or seizures. Benign intracranial hypertension has also been reported. Therapy with quinolones should be administered cautiously in patients with or predisposed to seizures or other CNS abnormalities. In addition, these patients should be advised to avoid the consumption of caffeine-containing products during therapy with some quinolones, most notably ciprofloxacin, enoxacin, and cinoxacin, since these agents can substantially reduce the clearance of caffeine and other methylxanthines, potentially resulting in severe CNS reactions.
Cirrhosis
Moderate:
Primethasone
The dexAMETHasone in Primethasone has a moderate potential interaction with Cirrhosis.
Corticosteroids may have enhanced effects on patients with cirrhosis due to decreased metabolism of these agents. Patients with cirrhosis should be monitored more closely for excessive cortisol effects. Dosage adjustments may be required in these patients.
Dehydration
Moderate:
delafloxacin
Delafloxacin has a moderate potential interaction with Dehydration.
Crystalluria has been reported rarely during quinolone therapy. Although it is not expected to occur under normal circumstances with usual recommended dosages, patients who are dehydrated (e.g., due to severe diarrhea or vomiting) may be at increased risk and should be encouraged to consume additional amounts of liquid or given intravenous fluid to ensure an adequate urinary output. Alkalinity of the urine should be avoided, since it may also increase the risk of crystalluria. Renal function tests should be performed periodically during prolonged therapy (> 2 weeks).
Depression
Moderate:
Primethasone
The dexAMETHasone in Primethasone has a moderate potential interaction with Depression.
Corticosteroids may aggravate the symptoms of psychosis and emotional instability. Patients with these conditions should be monitored for increased or worsened symptoms during corticosteroid therapy.
Diabetes Mellitus
Moderate:
delafloxacin
Delafloxacin has a moderate potential interaction with Diabetes Mellitus.
The use of certain quinolones has been associated with disturbances in blood glucose homeostasis possibly stemming from effects on pancreatic beta cell ATP-sensitive potassium channels that regulate insulin secretion. Hypoglycemia and, less frequently, hyperglycemia have been reported, although the latter may also occur due to infection alone. Hypoglycemia has usually occurred in patients with diabetes receiving concomitant oral hypoglycemic agents and/or insulin. Administration of ciprofloxacin, levofloxacin, norfloxacin, and especially gatifloxacin in patients treated with sulfonylureas or other oral hypoglycemic agents has resulted in severe, refractory hypoglycemia and hypoglycemic coma. Elderly patients and patients with reduced renal function are particularly susceptible. Blood glucose should be monitored more closely whenever quinolones are prescribed to patients with diabetes. Gatifloxacin has been known to cause hypoglycemic episodes generally within the first 3 days of therapy and sometimes even after the first dose, while hyperglycemia usually occurs 4 to 10 days after initiation of therapy. Patients should be counseled to recognize symptoms of hypoglycemia such as headache, dizziness, drowsiness, nausea, tremor, weakness, hunger, excessive perspiration, and palpitations. If hypo- or hyperglycemia occur during quinolone therapy, patients should initiate appropriate remedial therapy immediately, discontinue the antibiotic, and contact their physician.

Corticosteroids can raise blood glucose level by antagonizing the action and suppressing the secretion of insulin, which results in inhibition of peripheral glucose uptake and increased gluconeogenesis. Therapy with corticosteroids should be administered cautiously in patients with diabetes mellitus, glucose intolerance, or a predisposition to hyperglycemia. Patients with diabetes mellitus should be monitored more closely during corticosteroid therapy, and their antidiabetic regimen adjusted accordingly.
Diarrhea
Moderate:
delafloxacin
Delafloxacin has a moderate potential interaction with Diarrhea.
Crystalluria has been reported rarely during quinolone therapy. Although it is not expected to occur under normal circumstances with usual recommended dosages, patients who are dehydrated (e.g., due to severe diarrhea or vomiting) may be at increased risk and should be encouraged to consume additional amounts of liquid or given intravenous fluid to ensure an adequate urinary output. Alkalinity of the urine should be avoided, since it may also increase the risk of crystalluria. Renal function tests should be performed periodically during prolonged therapy (> 2 weeks).
Diverticulitis
Moderate:
Primethasone
The dexAMETHasone in Primethasone has a moderate potential interaction with Diverticulitis.
Corticosteroids may cause gastrointestinal perforation and hemorrhage, usually when given in high dosages or for prolonged periods. They may also mask symptoms of complications such as peritonitis or intraabdominal sepsis. Therapy with corticosteroids should be avoided or administered cautiously in patients with diverticulitis, nonspecific ulcerative colitis (if there is a probability of impending perforation, abscess, or other pyogenic infection), or recent intestinal anastomoses.
Electrolyte Abnormalities
Moderate:
Primethasone
The dexAMETHasone in Primethasone has a moderate potential interaction with Electrolyte Abnormalities.
Corticosteroids can cause hypernatremia, hypokalemia, and fluid retention. These mineralocorticoid effects are most significant with fludrocortisone, followed by hydrocortisone and cortisone, then by prednisone and prednisolone. The remaining corticosteroids, betamethasone, dexamethasone, methylprednisolone, and triamcinolone, have little mineralocorticoid activities. However, large doses of any corticosteroid can demonstrate these effects, particularly if given for longer than brief periods. All corticosteroids also increase excretion of calcium and can cause hypocalcemia. Therapy with corticosteroids should be administered cautiously in patients with preexisting electrolyte disturbances. Caution is also advised when treating patients with seizure disorders, since electrolyte disturbances may trigger seizure activity.
Fluid Retention
Moderate:
Primethasone
The dexAMETHasone in Primethasone has a moderate potential interaction with Fluid Retention.
Corticosteroids may cause hypernatremia, hypokalemia, fluid retention, and elevation in blood pressure. Large doses of any corticosteroid can demonstrate these effects, particularly if given for longer periods. Therapy with corticosteroids should be administered cautiously in patients with preexisting fluid retention, hypertension, congestive heart failure, and/or renal dysfunction. Dietary sodium restriction and potassium supplementation may be advisable.
Glaucoma/Intraocular Hypertension
Moderate:
Primethasone
The dexAMETHasone in Primethasone has a moderate potential interaction with Glaucoma/Intraocular Hypertension.
Prolonged use of corticosteroids may cause posterior subcapsular cataracts and elevated intraocular pressure, the latter of which may lead to glaucoma and/or damage to the optic nerves. Long-term therapy with corticosteroids should be administered cautiously in patients with a history of cataracts, glaucoma, or increased intraocular pressure.
Heart Attack
Moderate:
Primethasone
The dexAMETHasone in Primethasone has a moderate potential interaction with Heart Attack.
The use of corticosteroids may be associated with left ventricular free-wall rupture in patients who have had a recent myocardial infarction. Pharmacologic dosages of corticosteroids should be administered with great caution in such patients.
Heart Failure
Moderate:
Primethasone
The dexAMETHasone in Primethasone has a moderate potential interaction with Heart Failure.
Corticosteroids may cause hypernatremia, hypokalemia, fluid retention, and elevation in blood pressure. Large doses of any corticosteroid can demonstrate these effects, particularly if given for longer periods. Therapy with corticosteroids should be administered cautiously in patients with preexisting fluid retention, hypertension, congestive heart failure, and/or renal dysfunction. Dietary sodium restriction and potassium supplementation may be advisable.
Herpetic Keratitis
Moderate:
Primethasone
The dexAMETHasone in Primethasone has a moderate potential interaction with Herpetic Keratitis.
Pharmacologic dosages of corticosteroids should be used cautiously in patients with ocular herpes simplex because of the risk of corneal perforation. Corticosteroids are not recommended for patients with active ocular herpes simplex.
High Blood Pressure
Moderate:
Primethasone
The dexAMETHasone in Primethasone has a moderate potential interaction with High Blood Pressure.
Corticosteroids may cause hypernatremia, hypokalemia, fluid retention, and elevation in blood pressure. Large doses of any corticosteroid can demonstrate these effects, particularly if given for longer periods. Therapy with corticosteroids should be administered cautiously in patients with preexisting fluid retention, hypertension, congestive heart failure, and/or renal dysfunction. Dietary sodium restriction and potassium supplementation may be advisable.
High Cholesterol
Moderate:
Primethasone
The dexAMETHasone in Primethasone has a moderate potential interaction with High Cholesterol.
Corticosteroids may elevate serum triglyceride and LDL cholesterol levels if used for longer than brief periods. Patients with preexisting hyperlipidemia may require closer monitoring during prolonged corticosteroid therapy, and adjustments made accordingly in their lipid-lowering regimen.
History, Peptic Ulcer
Moderate:
Primethasone
The dexAMETHasone in Primethasone has a moderate potential interaction with History, Peptic Ulcer.
Corticosteroids may cause peptic ulcer disease and gastrointestinal (GI) hemorrhage, usually when given in high dosages or for prolonged periods. However, even conventional dosages may aggravate symptoms in patients with a history of peptic ulcers. Delayed healing of ulcers has also been reported. Therapy with corticosteroids should be avoided or administered cautiously in patients with active or latent peptic ulcers or other risk factors for GI bleeding. Some clinicians recommend the use of prophylactic antacids or H2-antagonists between meals when large doses of corticosteroids are necessary.
History, Thrombotic/Thromboembolic Disorder
Moderate:
Primethasone
The dexAMETHasone in Primethasone has a moderate potential interaction with History, Thrombotic/Thromboembolic Disorder.
Corticosteroids may increase blood coagulability and have rarely been associated with the development of intravascular thrombosis, thromboembolism, and thrombophlebitis. Therapy with corticosteroids should be administered cautiously in patients who have or may be predisposed to thrombotic or thromboembolic disorders.
History, Tuberculosis
Moderate:
Primethasone
The dexAMETHasone in Primethasone has a moderate potential interaction with History, Tuberculosis.
In patients with latent tuberculosis or tuberculin reactivity, the use of pharmacologic dosages of corticosteroids may cause a reactivation of the disease. Close monitoring for signs and symptoms of tuberculosis is recommended if corticosteroid therapy is administered to patients with a history of tuberculosis or tuberculin reactivity. During prolonged corticosteroid therapy, tuberculosis chemoprophylaxis may be considered.
Hyperadrenocorticism
Moderate:
Primethasone
The dexAMETHasone in Primethasone has a moderate potential interaction with Hyperadrenocorticism.
Corticosteroids mimic the effects of endogenous cortisol and aldosterone. Use of these agents may aggravate conditions of hyperadrenocorticalism in a dose-dependent manner.
Hyperaldosteronism
Moderate:
Primethasone
The dexAMETHasone in Primethasone has a moderate potential interaction with Hyperaldosteronism.
Corticosteroids mimic the effects of endogenous cortisol and aldosterone. Use of these agents may aggravate conditions of hyperadrenocorticalism in a dose-dependent manner.
Hypernatremia
Moderate:
Primethasone
The dexAMETHasone in Primethasone has a moderate potential interaction with Hypernatremia.
Corticosteroids can cause hypernatremia, hypokalemia, and fluid retention. These mineralocorticoid effects are most significant with fludrocortisone, followed by hydrocortisone and cortisone, then by prednisone and prednisolone. The remaining corticosteroids, betamethasone, dexamethasone, methylprednisolone, and triamcinolone, have little mineralocorticoid activities. However, large doses of any corticosteroid can demonstrate these effects, particularly if given for longer than brief periods. All corticosteroids also increase excretion of calcium and can cause hypocalcemia. Therapy with corticosteroids should be administered cautiously in patients with preexisting electrolyte disturbances. Caution is also advised when treating patients with seizure disorders, since electrolyte disturbances may trigger seizure activity.
Hypocalcemia
Moderate:
Primethasone
The dexAMETHasone in Primethasone has a moderate potential interaction with Hypocalcemia.
Corticosteroids can cause hypernatremia, hypokalemia, and fluid retention. These mineralocorticoid effects are most significant with fludrocortisone, followed by hydrocortisone and cortisone, then by prednisone and prednisolone. The remaining corticosteroids, betamethasone, dexamethasone, methylprednisolone, and triamcinolone, have little mineralocorticoid activities. However, large doses of any corticosteroid can demonstrate these effects, particularly if given for longer than brief periods. All corticosteroids also increase excretion of calcium and can cause hypocalcemia. Therapy with corticosteroids should be administered cautiously in patients with preexisting electrolyte disturbances. Caution is also advised when treating patients with seizure disorders, since electrolyte disturbances may trigger seizure activity.
Hypokalemia
Moderate:
Primethasone
The dexAMETHasone in Primethasone has a moderate potential interaction with Hypokalemia.
Corticosteroids can cause hypernatremia, hypokalemia, and fluid retention. These mineralocorticoid effects are most significant with fludrocortisone, followed by hydrocortisone and cortisone, then by prednisone and prednisolone. The remaining corticosteroids, betamethasone, dexamethasone, methylprednisolone, and triamcinolone, have little mineralocorticoid activities. However, large doses of any corticosteroid can demonstrate these effects, particularly if given for longer than brief periods. All corticosteroids also increase excretion of calcium and can cause hypocalcemia. Therapy with corticosteroids should be administered cautiously in patients with preexisting electrolyte disturbances. Caution is also advised when treating patients with seizure disorders, since electrolyte disturbances may trigger seizure activity.
Infection
Major:
Primethasone
The dexAMETHasone in Primethasone has a major potential interaction with Infection.
The immunosuppressant and anti-inflammatory effects of corticosteroids, particularly at higher dosages, may reduce resistance to infectious agents, increase the risk of disseminated infections, mask symptoms of infection, and reactivate or exacerbate latent/resolved infections; fatal cases have been reported. Avoid use of corticosteroids in patients with cerebral malaria. Screen patients for active (or history of) infection with tuberculosis, hepatitis, varicella, measles, and amebiasis, especially prior to prolonged treatment. Closely monitor for reactivation of latent infections; chemoprophylaxis may be required. In general, corticosteroids should not be used in patients with active infections, especially systemic fungal infections, unless medically necessary to control drug reactions. However, for corticosteroid-dependent patients who develop a severe or life-threatening infection, continuation of corticosteroid therapy with at least physiologic replacement dosages should be considered, since these patients may have secondary adrenocortical insufficiency. Removal of external steroid during periods of stress may be detrimental to these patients.
Intestinal Anastomoses
Moderate:
Primethasone
The dexAMETHasone in Primethasone has a moderate potential interaction with Intestinal Anastomoses.
Corticosteroids may cause gastrointestinal perforation and hemorrhage, usually when given in high dosages or for prolonged periods. They may also mask symptoms of complications such as peritonitis or intraabdominal sepsis. Therapy with corticosteroids should be avoided or administered cautiously in patients with diverticulitis, nonspecific ulcerative colitis (if there is a probability of impending perforation, abscess, or other pyogenic infection), or recent intestinal anastomoses.
Liver Disease
Moderate:
Primethasone
The dexAMETHasone in Primethasone has a moderate potential interaction with Liver Disease.
Corticosteroids are primarily metabolized by the liver and may have enhanced effects in patients with liver disease. Dosage adjustments may be necessary in these patients.
Myasthenia Gravis
Major:
delafloxacin
Delafloxacin has a major potential interaction with Myasthenia Gravis.
Fluoroquinolones have neuromuscular blocking activity and may exacerbate muscle weakness in persons with myasthenia gravis. Postmarketing serious adverse events, including deaths and requirement for ventilatory support, have been associated with fluoroquinolones use in persons with myasthenia gravis. Fluoroquinolones should be avoided in patients with history of myasthenia gravis.
Moderate:
Primethasone
The dexAMETHasone in Primethasone has a moderate potential interaction with Myasthenia Gravis.
Although corticosteroids are commonly used in the treatment of myasthenia gravis to increase muscle strength, these agents should nevertheless be administered with caution in such setting. Patients should be treated in an intensive care unit and receive respiratory support, since muscle strength may markedly decrease initially, particularly with high dosages. Preferably, therapy should begin with relatively low dosages (15 to 25 mg/day of prednisone or equivalent) and be increased stepwise as tolerated (approximately 5 mg/day of prednisone or equivalent at 2- to 3-day intervals until marked clinical improvement or a dosage of 50 mg/day is reached). Improvement may be delayed and gradual. Thus, it is important not to discontinue therapy prematurely.
Myoneural Disorder
Moderate:
Primethasone
The dexAMETHasone in Primethasone has a moderate potential interaction with Myoneural Disorder.
Toxic myopathy has been observed with the chronic use or the administration of large doses of corticosteroids, often in patients with disorders of neuromuscular transmission such as myasthenia gravis or in patients receiving neuromuscular blocking agents. Fluorinated corticosteroids such as betamethasone, dexamethasone, and triamcinolone appear to cause more severe muscle atrophy and weakness than the nonfluorinated agents. Moreover, multiple-daily doses are more toxic than once-daily or, preferably, alternate-day morning doses. Steroid myopathy is generalized and sometimes accompanied by respiratory weakness and dyspnea. In some cases, it has resulted in quadriparesis. Elevations of creatine kinase (CK) may also occur, albeit infrequently. After withdrawal of corticosteroid therapy, recovery may be slow and incomplete. Therapy with corticosteroids should be administered cautiously in patients with preexisting myopathy or myoneural disorders since these conditions may confound the diagnosis of steroid-induced myopathy. The presence of a normal serum CK level, minimal/no changes of myopathy on electromyography, and type 2 muscle fiber atrophy on biopsy are helpful in suggesting steroid-induced weakness. If steroid myopathy is suspected, a dosage reduction or discontinuation of the steroid should be considered.
Myopathy
Moderate:
Primethasone
The dexAMETHasone in Primethasone has a moderate potential interaction with Myopathy.
Toxic myopathy has been observed with the chronic use or the administration of large doses of corticosteroids, often in patients with disorders of neuromuscular transmission such as myasthenia gravis or in patients receiving neuromuscular blocking agents. Fluorinated corticosteroids such as betamethasone, dexamethasone, and triamcinolone appear to cause more severe muscle atrophy and weakness than the nonfluorinated agents. Moreover, multiple-daily doses are more toxic than once-daily or, preferably, alternate-day morning doses. Steroid myopathy is generalized and sometimes accompanied by respiratory weakness and dyspnea. In some cases, it has resulted in quadriparesis. Elevations of creatine kinase (CK) may also occur, albeit infrequently. After withdrawal of corticosteroid therapy, recovery may be slow and incomplete. Therapy with corticosteroids should be administered cautiously in patients with preexisting myopathy or myoneural disorders since these conditions may confound the diagnosis of steroid-induced myopathy. The presence of a normal serum CK level, minimal/no changes of myopathy on electromyography, and type 2 muscle fiber atrophy on biopsy are helpful in suggesting steroid-induced weakness. If steroid myopathy is suspected, a dosage reduction or discontinuation of the steroid should be considered.
Noninfectious Colitis
Major:
delafloxacin
Delafloxacin has a major potential interaction with Noninfectious Colitis.
Clostridioides difficile-associated diarrhea (CDAD), formerly pseudomembranous colitis, has been reported with almost all antibacterial drugs and may range from mild diarrhea to fatal colitis. The most common culprits include clindamycin and lincomycin. Antibacterial therapy alters the normal flora of the colon, leading to overgrowth of C difficile, whose toxins A and B contribute to CDAD development. Morbidity and mortality are increased with hypertoxin-producing strains of C difficile; these infections can be resistant to antimicrobial therapy and may require colectomy. CDAD must be considered in all patients who present with diarrhea after antibacterial use. Since CDAD has been reported to occur more than 2 months after antibacterial use, careful medical history is necessary. Therapy with broad-spectrum antibacterials and other agents with significant antibacterial activity should be administered cautiously in patients with history of gastrointestinal disease, particularly colitis; pseudomembranous colitis (generally characterized by severe, persistent diarrhea and severe abdominal cramps, and sometimes associated with the passage of blood and mucus), if it occurs, may be more severe in these patients and may be associated with flares in underlying disease activity. Antibacterial drugs not directed against C difficile may need to be stopped if CDAD is suspected or confirmed. Appropriate fluid and electrolyte management, protein supplementation, antibacterial treatment of C difficile, and surgical evaluation should be started as clinically indicated.
Organ Transplant
Major:
delafloxacin
Delafloxacin has a major potential interaction with Organ Transplant.
Tendonitis and ruptures of the shoulder, hand, and Achilles tendons have been reported in patients receiving quinolones, both during and after treatment. Avoid the use of these agents in patients who have a history of tendon disorders or have experienced tendinitis or tendon rupture. Therapy with quinolones should be administered cautiously in patients with patients with kidney, heart, and lung transplant, since it may delay the recognition or confound the diagnosis of a quinolone-induced musculoskeletal effect. Factors that may independently increase the risk of tendon rupture include strenuous physical activity, renal failure, and previous tendon disorders such as rheumatoid arthritis. It is recommended to discontinue these agents if, at any time during therapy, pain, inflammation or rupture of a tendon develops and institute appropriate treatment.
Osteoporosis
Moderate:
Primethasone
The dexAMETHasone in Primethasone has a moderate potential interaction with Osteoporosis.
Corticosteroids reduce osteoblastic function and inhibit the absorption of intestinal calcium, which can result in bone resorption and bone loss during prolonged therapy. In addition, bone matrix may be affected by the protein-catabolic effects of corticosteroids, especially when given in high dosages or for prolonged periods, leading to aseptic necrosis and fractures. Long-term or high-dose corticosteroid therapy should be administered cautiously and only if necessary in patients with or at risk for osteoporosis. Adverse skeletal effects may be minimized by alternate-day or intermittent administration. Any patient receiving prolonged therapy with the equivalent of 7.5 mg prednisone/day or more are at risk for glucocorticoid-induced osteoporosis and should be managed according to The American College of Rheumatology (ACR) guidelines.
Peptic Ulcer
Moderate:
Primethasone
The dexAMETHasone in Primethasone has a moderate potential interaction with Peptic Ulcer.
Corticosteroids may cause peptic ulcer disease and gastrointestinal (GI) hemorrhage, usually when given in high dosages or for prolonged periods. However, even conventional dosages may aggravate symptoms in patients with a history of peptic ulcers. Delayed healing of ulcers has also been reported. Therapy with corticosteroids should be avoided or administered cautiously in patients with active or latent peptic ulcers or other risk factors for GI bleeding. Some clinicians recommend the use of prophylactic antacids or H2-antagonists between meals when large doses of corticosteroids are necessary.
Peripheral Neuropathy
Major:
delafloxacin
Delafloxacin has a major potential interaction with Peripheral Neuropathy.
The use of quinolones has been associated with an increased risk of peripheral neuropathy. Monitor closely and discontinue their use in patients experiencing symptoms of peripheral neuropathy. It is recommended to avoid these agents in patients who have previously experienced peripheral neuropathy.
Post MI Syndrome
Moderate:
Primethasone
The dexAMETHasone in Primethasone has a moderate potential interaction with Post MI Syndrome.
The use of corticosteroids may be associated with left ventricular free-wall rupture in patients who have had a recent myocardial infarction. Pharmacologic dosages of corticosteroids should be administered with great caution in such patients.
Prematurity/Underweight in Infancy
Major:
Primethasone
The dexAMETHasone in Primethasone has a major potential interaction with Prematurity/Underweight in Infancy.
The use of certain parenteral formulations of dexamethasone, hydrocortisone, methylprednisolone, prednisolone and triamcinolone is considered by the drug manufacturers to be contraindicated in neonates, particularly premature infants and infants of low birth weight. Some formulations of these drugs contain benzyl alcohol which, when used in bacteriostatic saline intravascular flush and endotracheal tube lavage solutions, has been associated with fatalities and severe respiratory and metabolic complications in low-birth-weight premature infants. However, many experts feel that, in the absence of benzyl alcohol-free equivalents, the amount of the preservative present in these formulations should not necessarily preclude their use if they are clearly indicated. The American Academy of Pediatrics considers benzyl alcohol in low doses (such as when used as a preservative in some medications) to be safe for newborns. Continuous infusions of high dosages of medications containing benzyl alcohol may, however, cause toxicity and should be avoided if possible.
Psychosis
Moderate:
Primethasone
The dexAMETHasone in Primethasone has a moderate potential interaction with Psychosis.
Corticosteroids may aggravate the symptoms of psychosis and emotional instability. Patients with these conditions should be monitored for increased or worsened symptoms during corticosteroid therapy.
Renal Dysfunction
Major:
delafloxacin
Delafloxacin has a major potential interaction with Renal Dysfunction.
The use of delafloxacin is not recommended in patients with End Stage Renal Disease (ESRD). In patients with severe renal impairment or ESRD, accumulation of the intravenous vehicle, sulfobutylether-beta-cyclodextrin (SBECD) occurs. No dosage adjustment is necessary in patients with mild or moderate renal impairment. The dose of delafloxacin intravenous IV infusion in patients with severe renal impairment should be decreased to 200 mg intravenously every 12 hours; the oral dose in patients with severe renal impairment is 450 mg orally every 12 hours. It is recommended to closely monitor serum creatinine in patients with severe renal impairment receiving intravenous delafloxacin and if serum creatinine level increases, consideration should be given to changing to the oral form of delafloxacin. If eGFR decreases to <15 mL/min/1.73 m2, the drug should be discontinued.
Major:
delafloxacin
Delafloxacin has a major potential interaction with Renal Dysfunction.
Tendonitis and ruptures of the shoulder, hand, and Achilles tendons have been reported in patients receiving quinolones, both during and after treatment. Avoid the use of these agents in patients who have a history of tendon disorders or have experienced tendinitis or tendon rupture. Therapy with quinolones should be administered cautiously in patients with patients with kidney, heart, and lung transplant, since it may delay the recognition or confound the diagnosis of a quinolone-induced musculoskeletal effect. Factors that may independently increase the risk of tendon rupture include strenuous physical activity, renal failure, and previous tendon disorders such as rheumatoid arthritis. It is recommended to discontinue these agents if, at any time during therapy, pain, inflammation or rupture of a tendon develops and institute appropriate treatment.
Moderate:
Primethasone
The dexAMETHasone in Primethasone has a moderate potential interaction with Renal Dysfunction.
Corticosteroids may cause hypernatremia, hypokalemia, fluid retention, and elevation in blood pressure. Large doses of any corticosteroid can demonstrate these effects, particularly if given for longer periods. Therapy with corticosteroids should be administered cautiously in patients with preexisting fluid retention, hypertension, congestive heart failure, and/or renal dysfunction. Dietary sodium restriction and potassium supplementation may be advisable.
Rheumatoid Arthritis
Major:
delafloxacin
Delafloxacin has a major potential interaction with Rheumatoid Arthritis.
Tendonitis and ruptures of the shoulder, hand, and Achilles tendons have been reported in patients receiving quinolones, both during and after treatment. Avoid the use of these agents in patients who have a history of tendon disorders or have experienced tendinitis or tendon rupture. Therapy with quinolones should be administered cautiously in patients with patients with kidney, heart, and lung transplant, since it may delay the recognition or confound the diagnosis of a quinolone-induced musculoskeletal effect. Factors that may independently increase the risk of tendon rupture include strenuous physical activity, renal failure, and previous tendon disorders such as rheumatoid arthritis. It is recommended to discontinue these agents if, at any time during therapy, pain, inflammation or rupture of a tendon develops and institute appropriate treatment.
Seizures
Moderate:
Primethasone
The dexAMETHasone in Primethasone has a moderate potential interaction with Seizures.
Corticosteroids can cause hypernatremia, hypokalemia, and fluid retention. These mineralocorticoid effects are most significant with fludrocortisone, followed by hydrocortisone and cortisone, then by prednisone and prednisolone. The remaining corticosteroids, betamethasone, dexamethasone, methylprednisolone, and triamcinolone, have little mineralocorticoid activities. However, large doses of any corticosteroid can demonstrate these effects, particularly if given for longer than brief periods. All corticosteroids also increase excretion of calcium and can cause hypocalcemia. Therapy with corticosteroids should be administered cautiously in patients with preexisting electrolyte disturbances. Caution is also advised when treating patients with seizure disorders, since electrolyte disturbances may trigger seizure activity.
Strongyloidiasis
Moderate:
Primethasone
The dexAMETHasone in Primethasone has a moderate potential interaction with Strongyloidiasis.
Unlike most helminths, Strongyloides stercoralis has the ability to replicate in the human host. In patients with strongyloidiasis, the use of pharmacologic or immunosuppressive dosages of corticosteroids may result in Strongyloides hyperinfection and dissemination with widespread larval migration, often accompanied by severe enterocolitis and potentially fatal gram-negative septicemia. Therapy with corticosteroids should be administered with extreme caution, if at all, in these patients. For patients on corticosteroids who develop known or suspected Strongyloides infestation, withdrawal of corticosteroids or reduction of the dose of corticosteroids is recommended.
Systemic Sclerosis
Moderate:
Primethasone
The dexAMETHasone in Primethasone has a moderate potential interaction with Systemic Sclerosis.
In patients with scleroderma, corticosteroids may precipitate renal crisis with malignant hypertension, possibly via steroid-induced increases in renin substrate and angiotensin II levels and decreases in vasodilator prostaglandin production. Renal failure may ensue. Therapy with corticosteroids should be administered cautiously in patients with scleroderma. In addition, they should be limited to short-term use.
Tendonitis
Major:
delafloxacin
Delafloxacin has a major potential interaction with Tendonitis.
Tendonitis and ruptures of the shoulder, hand, and Achilles tendons have been reported in patients receiving quinolones, both during and after treatment. Avoid the use of these agents in patients who have a history of tendon disorders or have experienced tendinitis or tendon rupture. Therapy with quinolones should be administered cautiously in patients with patients with kidney, heart, and lung transplant, since it may delay the recognition or confound the diagnosis of a quinolone-induced musculoskeletal effect. Factors that may independently increase the risk of tendon rupture include strenuous physical activity, renal failure, and previous tendon disorders such as rheumatoid arthritis. It is recommended to discontinue these agents if, at any time during therapy, pain, inflammation or rupture of a tendon develops and institute appropriate treatment.
Thrombotic/Thromboembolic Disorder
Moderate:
Primethasone
The dexAMETHasone in Primethasone has a moderate potential interaction with Thrombotic/Thromboembolic Disorder.
Corticosteroids may increase blood coagulability and have rarely been associated with the development of intravascular thrombosis, thromboembolism, and thrombophlebitis. Therapy with corticosteroids should be administered cautiously in patients who have or may be predisposed to thrombotic or thromboembolic disorders.
Tuberculosis, Latent
Moderate:
Primethasone
The dexAMETHasone in Primethasone has a moderate potential interaction with Tuberculosis, Latent.
In patients with latent tuberculosis or tuberculin reactivity, the use of pharmacologic dosages of corticosteroids may cause a reactivation of the disease. Close monitoring for signs and symptoms of tuberculosis is recommended if corticosteroid therapy is administered to patients with a history of tuberculosis or tuberculin reactivity. During prolonged corticosteroid therapy, tuberculosis chemoprophylaxis may be considered.
Ulcerative Colitis
Moderate:
Primethasone
The dexAMETHasone in Primethasone has a moderate potential interaction with Ulcerative Colitis.
Corticosteroids may cause gastrointestinal perforation and hemorrhage, usually when given in high dosages or for prolonged periods. They may also mask symptoms of complications such as peritonitis or intraabdominal sepsis. Therapy with corticosteroids should be avoided or administered cautiously in patients with diverticulitis, nonspecific ulcerative colitis (if there is a probability of impending perforation, abscess, or other pyogenic infection), or recent intestinal anastomoses.
Underactive Thyroid
Moderate:
Primethasone
The dexAMETHasone in Primethasone has a moderate potential interaction with Underactive Thyroid.
Corticosteroids may have enhanced effects in hypothyroidism due to decreased metabolism of these agents. Patients with hypothyroidism should be monitored more closely for excessive cortisol effects. Dosage adjustments may be required secondary to changes in their thyroid condition.
Vomiting
Moderate:
delafloxacin
Delafloxacin has a moderate potential interaction with Vomiting.
Crystalluria has been reported rarely during quinolone therapy. Although it is not expected to occur under normal circumstances with usual recommended dosages, patients who are dehydrated (e.g., due to severe diarrhea or vomiting) may be at increased risk and should be encouraged to consume additional amounts of liquid or given intravenous fluid to ensure an adequate urinary output. Alkalinity of the urine should be avoided, since it may also increase the risk of crystalluria. Renal function tests should be performed periodically during prolonged therapy (> 2 weeks).
