Disease interactions
29 potential interactions Applies to: 25 conditions, including Heart Failure, Seizures, Arrhythmia, Hypokalemia, and Hypotension.
Abnormal Electrocardiogram
Major:
telithromycin
Telithromycin has a major potential interaction with Abnormal Electrocardiogram.
Telithromycin may prolong the QTc interval of the electrocardiogram in some patients. QTC prolongation has been associated with an increased risk of ventricular arrhythmias including ventricular tachycardia, ventricular fibrillation, and torsade de pointes. No cardiovascular morbidity or mortality attributable to QTc prolongation occurred with telithromycin treatment in nearly 5000 patients in clinical efficacy trials, including 204 patients who had a prolonged QTc interval at baseline. In addition, a pharmacokinetic study found no significant QT prolongation in 34 healthy volunteers at all heart rates tested following telithromycin administered as repeated doses of 800 mg or as single doses of up to 2400 mg. Nevertheless, therapy with telithromycin should be avoided in patients with preexisting arrhythmia or congenital prolongation of the QTc interval. It should also be avoided in the presence of proarrhythmic conditions such as uncorrected hypokalemia or hypomagnesemia; clinically significant bradycardia; or concomitant use of class IA or III antiarrhythmic drugs or other medications that are known to produce an increase in the QTc interval.
Acidosis
Moderate:
Flavalta
The EPINEPHrine in Flavalta has a moderate potential interaction with Acidosis.
Acidosis, hypoxia, and hypercapnia may reduce the effectiveness of sympathomimetic amines in raising blood pressure. These conditions should be corrected before initiating therapy with sympathomimetic amines, if possible. Monitoring the patients acid-base balance, carbon dioxide levels, and oxygen saturation is recommended.
Alcoholism
Major:
telithromycin
Telithromycin has a major potential interaction with Alcoholism.
Hepatic dysfunction, including elevated liver enzymes and hepatitis, with or without jaundice, has been reported with the use of telithromycin. Although these events are generally reversible, liver failure resulting in transplantation or death has been reported rarely during postmarketing use. Alcohol use may have been a contributing factor in some of the severe cases. Therapy with telithromycin should preferably be avoided in patients with alcoholism, liver disease, or a prior history of hepatitis/jaundice associated with use of the drug. Patients treated with telithromycin should be instructed to discontinue the drug and seek medical attention promptly if signs and symptoms of hepatic injury develop such as fever, pruritus, rash, anorexia, nausea, vomiting, fatigue, right upper quadrant pain, dark urine, and jaundice.
The pharmacokinetics of telithromycin is not significantly altered in the presence of hepatic impairment due to a compensatory increase in renal elimination. No dosage adjustment is necessary unless renal function is also severely impaired (CrCl < 30 mL/min).
Arrhythmia
Major:
telithromycin
Telithromycin has a major potential interaction with Arrhythmia.
Telithromycin may prolong the QTc interval of the electrocardiogram in some patients. QTC prolongation has been associated with an increased risk of ventricular arrhythmias including ventricular tachycardia, ventricular fibrillation, and torsade de pointes. No cardiovascular morbidity or mortality attributable to QTc prolongation occurred with telithromycin treatment in nearly 5000 patients in clinical efficacy trials, including 204 patients who had a prolonged QTc interval at baseline. In addition, a pharmacokinetic study found no significant QT prolongation in 34 healthy volunteers at all heart rates tested following telithromycin administered as repeated doses of 800 mg or as single doses of up to 2400 mg. Nevertheless, therapy with telithromycin should be avoided in patients with preexisting arrhythmia or congenital prolongation of the QTc interval. It should also be avoided in the presence of proarrhythmic conditions such as uncorrected hypokalemia or hypomagnesemia; clinically significant bradycardia; or concomitant use of class IA or III antiarrhythmic drugs or other medications that are known to produce an increase in the QTc interval.
Autoimmune Hepatitis
Major:
telithromycin
Telithromycin has a major potential interaction with Autoimmune Hepatitis.
The use of telithromycin is contraindicated in patients with previous history of hepatitis and/or jaundice associated with the use of any macrolide antibacterial agent.
Cardiovascular Conditions and Disorders
Major:
Flavalta
The EPINEPHrine in Flavalta has a major potential interaction with Cardiovascular Conditions and Disorders.
Sympathomimetic agents may cause adverse cardiovascular effects, particularly when used in high dosages and/or in susceptible patients. In cardiac tissues, these agents may produce positive chronotropic and inotropic effects via stimulation of beta- 1 adrenergic receptors. Cardiac output, oxygen consumption, and the work of the heart may be increased. In the peripheral vasculature, vasoconstriction may occur via stimulation of alpha-1 adrenergic receptors. Palpitations, tachycardia, arrhythmia, hypertension, reflex bradycardia, coronary occlusion, cerebral vasculitis, myocardial infarction, cardiac arrest, and death have been reported. Some of these agents, particularly ephedra alkaloids (ephedrine, ma huang, phenylpropanolamine), may also predispose patients to hemorrhagic and ischemic stroke. Therapy with sympathomimetic agents should generally be avoided or administered cautiously in patients with sensitivity to sympathomimetic amines, hyperthyroidism, or underlying cardiovascular or cerebrovascular disorders. These agents should not be used in patients with severe coronary artery disease or severe/uncontrolled hypertension.
Dehydration
Major:
Flavalta
The EPINEPHrine in Flavalta has a major potential interaction with Dehydration.
The use of sympathomimetic amines has been infrequently associated with significant hypotension especially in dehydrated patients secondary to the drug's beta-2 mediated vasodilation. Hypovolemia should be corrected, if possible, before administering sympathomimetic amines. Blood pressure and ECG should be monitored at regular intervals. Monitoring of cardiac output and pulmonary wedge pressure may also be desired.
Diabetes Mellitus
Moderate:
Flavalta
The EPINEPHrine in Flavalta has a moderate potential interaction with Diabetes Mellitus.
Sympathomimetic agents may cause increases in blood glucose concentrations. These effects are usually transient and slight but may be significant with dosages higher than those normally recommended. Therapy with sympathomimetic agents should be administered cautiously in patients with diabetes mellitus. Closer monitoring of blood glucose concentrations may be appropriate.
Electrolyte Abnormalities
Major:
telithromycin
Telithromycin has a major potential interaction with Electrolyte Abnormalities.
Telithromycin may prolong the QTc interval of the electrocardiogram in some patients. QTC prolongation has been associated with an increased risk of ventricular arrhythmias including ventricular tachycardia, ventricular fibrillation, and torsade de pointes. No cardiovascular morbidity or mortality attributable to QTc prolongation occurred with telithromycin treatment in nearly 5000 patients in clinical efficacy trials, including 204 patients who had a prolonged QTc interval at baseline. In addition, a pharmacokinetic study found no significant QT prolongation in 34 healthy volunteers at all heart rates tested following telithromycin administered as repeated doses of 800 mg or as single doses of up to 2400 mg.

It should also be avoided in the presence of proarrhythmic conditions such as uncorrected hypokalemia or hypomagnesemia; clinically significant bradycardia; or concomitant use of class IA or III antiarrhythmic drugs or other medications that are known to produce an increase in the QTc interval.
Heart Block
Major:
Flavalta
The lidocaine in Flavalta has a major potential interaction with Heart Block.
The use of lidocaine is contraindicated in patients with Stokes-Adam syndrome, Wolff-Parkinson White syndrome, or second- or third-degree AV block in the absence of a functional artificial pacemaker, or congenital QT prolongation.
Heart Failure
Major:
Flavalta
The lidocaine in Flavalta has a major potential interaction with Heart Failure.
Antiarrhythmic agents can induce severe hypotension (particularly with IV administration) or induce or worsen congestive heart failure (CHF). Patients with primary cardiomyopathy or inadequately compensated CHF are at increased risk. Antiarrhythmic agents should be administered cautiously and dosage and/or frequency of administration modified in patients with hypotension or adequately compensated CHF. Alternative therapy should be considered unless these conditions are secondary to cardiac arrhythmia.
Hemodialysis
Moderate:
telithromycin
Telithromycin has a moderate potential interaction with Hemodialysis.
The effect of hemodialysis on removing telithromycin from the body has not been studied. Doses should be given after the dialysis session on dialysis days.
Hyperkalemia
Moderate:
Flavalta
The lidocaine in Flavalta has a moderate potential interaction with Hyperkalemia.
Electrolyte imbalance can alter the therapeutic effectiveness of antiarrhythmic agents. Hypokalemia and hypomagnesemia can reduce the effectiveness of antiarrhythmic agents. In some cases, these disorders can exaggerate the degree of QTc prolongation and increase the potential for torsade de pointes. Hyperkalemia can potentiate the toxic effects of antiarrhythmic agents. Electrolyte imbalance should be corrected prior to initiating antiarrhythmic therapy. Clinical monitoring of cardiac function and electrolyte concentrations is recommended.
Hyperthyroidism
Major:
Flavalta
The EPINEPHrine in Flavalta has a major potential interaction with Hyperthyroidism.
Sympathomimetic agents may cause adverse cardiovascular effects, particularly when used in high dosages and/or in susceptible patients. In cardiac tissues, these agents may produce positive chronotropic and inotropic effects via stimulation of beta- 1 adrenergic receptors. Cardiac output, oxygen consumption, and the work of the heart may be increased. In the peripheral vasculature, vasoconstriction may occur via stimulation of alpha-1 adrenergic receptors. Palpitations, tachycardia, arrhythmia, hypertension, reflex bradycardia, coronary occlusion, cerebral vasculitis, myocardial infarction, cardiac arrest, and death have been reported.

In some cases, these disorders can exaggerate the degree of QTc prolongation and increase the potential for torsade de pointes. Hyperkalemia can potentiate the toxic effects of antiarrhythmic agents. Electrolyte imbalance should be corrected prior to initiating antiarrhythmic therapy. Clinical monitoring of cardiac function and electrolyte concentrations is recommended.
Hypotension
Major:
Flavalta
The lidocaine in Flavalta has a major potential interaction with Hypotension.
Antiarrhythmic agents can induce severe hypotension (particularly with IV administration) or induce or worsen congestive heart failure (CHF). Patients with primary cardiomyopathy or inadequately compensated CHF are at increased risk. Antiarrhythmic agents should be administered cautiously and dosage and/or frequency of administration modified in patients with hypotension or adequately compensated CHF. Alternative therapy should be considered unless these conditions are secondary to cardiac arrhythmia.
Liver Disease
Major:
Flavalta
The lidocaine in Flavalta has a major potential interaction with Liver Disease.
Lidocaine is rapidly and extensively metabolized by the liver. Less than 10% is eliminated unchanged in the urine. Several inactive and two active forms (MEGX and GX) have been identified. MEGX and GX exhibit antiarrhythmic and convulsant properties. GX accumulates during prolonged intravenous lidocaine infusion. The pharmacokinetic disposition of lidocaine is altered by changes in hepatic function, including hepatic blood flow. Therapy with lidocaine should be administered cautiously and dosing modifications for repeated or loading and maintenance doses may be necessary. Clinical monitoring of cardiac (continuous ECG) is required and serum metabolite concentrations and monitoring hepatic function are recommended.
Major:
telithromycin
Telithromycin has a major potential interaction with Liver Disease.
Hepatic dysfunction, including elevated liver enzymes and hepatitis, with or without jaundice, has been reported with the use of telithromycin.

In some cases, these disorders can exaggerate the degree of QTc prolongation and increase the potential for torsade de pointes. Hyperkalemia can potentiate the toxic effects of antiarrhythmic agents. Electrolyte imbalance should be corrected prior to initiating antiarrhythmic therapy. Clinical monitoring of cardiac function and electrolyte concentrations is recommended.
Myasthenia Gravis
Major:
telithromycin
Telithromycin has a major potential interaction with Myasthenia Gravis.
Telithromycin is contraindicated in patients with myasthenia gravis. There have been reports of fatal and life-threatening respiratory failure in patients with myasthenia gravis associated with the use of this drug.
Neurological Disorders
Moderate:
Flavalta
The EPINEPHrine in Flavalta has a moderate potential interaction with Neurological Disorders.
Epinephrine should be administered with caution to patients with Parkinson's disease as these patients may experience psychomotor agitation or notice a temporary worsening of symptoms.
Noninfectious Colitis
Major:
telithromycin
Telithromycin 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.
Parkinsonism
Moderate:
Flavalta
The EPINEPHrine in Flavalta has a moderate potential interaction with Parkinsonism.
Epinephrine should be administered with caution to patients with Parkinson's disease as these patients may experience psychomotor agitation or notice a temporary worsening of symptoms.
Pheochromocytoma
Major:
Flavalta
The EPINEPHrine in Flavalta has a major potential interaction with Pheochromocytoma.
Sympathomimetic agents may cause adverse cardiovascular effects, particularly when used in high dosages and/or in susceptible patients. In cardiac tissues, these agents may produce positive chronotropic and inotropic effects via stimulation of beta- 1 adrenergic receptors. Cardiac output, oxygen consumption, and the work of the heart may be increased. In the peripheral vasculature, vasoconstriction may occur via stimulation of alpha-1 adrenergic receptors. Palpitations, tachycardia, arrhythmia, hypertension, reflex bradycardia, coronary occlusion, cerebral vasculitis, myocardial infarction, cardiac arrest, and death have been reported. Some of these agents, particularly ephedra alkaloids (ephedrine, ma huang, phenylpropanolamine), may also predispose patients to hemorrhagic and ischemic stroke. Therapy with sympathomimetic agents should generally be avoided or administered cautiously in patients with sensitivity to sympathomimetic amines, hyperthyroidism, or underlying cardiovascular or cerebrovascular disorders. These agents should not be used in patients with severe coronary artery disease or severe/uncontrolled hypertension.
Renal Dysfunction
Major:
Flavalta
The lidocaine in Flavalta has a major potential interaction with Renal Dysfunction.
Lidocaine is primarily eliminated by the kidney. Less than 10% is eliminated unchanged in the urine. Two active metabolites (MEGX and GX) have been identified that exhibit antiarrhythmic and convulsant properties. GX accumulates during prolonged intravenous lidocaine infusion. Serum concentrations of lidocaine and the active metabolites are increased and the half-life prolonged in patients with renal impairment. Therapy with lidocaine should be administered cautiously and dosing modified for repeated or maintenance doses in patients with compromised renal function. Clinical monitoring of cardiac function (continual ECG) is required and serum metabolite concentrations and monitoring renal function are recommended.
Moderate:
telithromycin
Telithromycin has a moderate potential interaction with Renal Dysfunction.
Telithromycin is eliminated by both renal and hepatic routes. In a multiple-dose study of subjects with varying degrees of renal impairment, patients classified as having severely impaired renal function (CrCl < 30 mL/min) had a 1.4-fold increase in steady-state peak plasma concentration (Cmax) and a 1.9-fold increase in systemic exposure (AUC) of telithromycin compared to healthy volunteers following administration of 800 mg once daily for 5 days. Renal excretion may serve as a compensatory elimination pathway for telithromycin in situations where metabolic clearance is impaired. In one study, coadministration of ketoconazole (which inhibits metabolism of telithromycin via CYP450 3A4) in 2 patients with severe renal impairment resulted in a 4- to 5-fold increase in telithromycin AUC compared to that in healthy subjects with normal renal function receiving telithromycin alone. Since patients with severe renal impairment are prone to conditions that may impair their metabolic clearance, telithromycin dosage should be reduced to 600 mg once daily in patients with severe renal impairment (CrCl < 30 mL/min), including those undergoing dialysis. The dosage should be further reduced to 400 mg once daily if there is coexisting hepatic impairment.
Seizures
Major:
Flavalta
The lidocaine in Flavalta has a major potential interaction with Seizures.
Seizures have occurred during lidocaine therapy and have been associated with the rapid administration of a large intravenous doses or accumulation of active metabolites with maintenance therapy. Therapy with lidocaine should be administered cautiously to patients with or predisposed to seizure disorders. Clinical monitoring of cardiac (continuous ECG) is required, and serum metabolite concentrations are recommended.
