Disease interactions
50 potential interactions Applies to: 43 conditions, including High Blood Pressure, High Cholesterol, Depression, GERD, and Vitamin D Deficiency.
Acute Alcohol Intoxication
Major:
Antispasmodic
The PHENobarbital in Antispasmodic has a major potential interaction with Acute Alcohol Intoxication.
The use of barbiturates is contraindicated in patients with acute alcohol intoxication exhibiting depressed vital signs. The central nervous system depressant effects of barbiturates may be additive with those of alcohol. Severe respiratory depression and death may occur. Therapy with barbiturates should be administered cautiously in patients who might be prone to acute alcohol intake.
Adrenal Insufficiency
Moderate:
Antispasmodic
The PHENobarbital in Antispasmodic has a moderate potential interaction with Adrenal Insufficiency.
Barbiturates, especially phenobarbital, secobarbital and butabarbital, may diminish the systemic effects of exogenous and endogenous corticosteroids via induction of hepatic microsomal enzymes, thereby accelerating the metabolism of corticosteroids. In addition, barbiturates may interfere with pituitary corticotropin production. Therapy with barbiturates should be administered cautiously in patients with adrenal insufficiency. Patients with borderline hypoadrenalism should be monitored closely, and patients receiving steroid supplementation may require an adjustment in dosage when barbiturates are added to or withdrawn from their medication regimen.
Alcoholism
Major:
Antispasmodic
The PHENobarbital in Antispasmodic has a major potential interaction with Alcoholism.
Barbiturates have the potential to cause dependence and abuse. Tolerance as well as physical and psychological dependence can develop, particularly after prolonged use of excessive dosages. Abrupt cessation and/or a reduction in dosage may precipitate withdrawal symptoms. In patients who have developed tolerance to a barbiturate, overdosage can still produce respiratory depression and death, and cross-tolerance usually will occur with other agents in the class. Addiction-prone individuals, such as those with a history of alcohol or substance abuse, should be under careful surveillance or medical supervision when treated with barbiturates. It may be prudent to refrain from dispensing large quantities of medication to these patients. After prolonged use or if dependency is suspected, withdrawal of barbiturates should be undertaken gradually using a dosage-tapering schedule.
Altered Consciousness
Major:
Antispasmodic
The PHENobarbital in Antispasmodic has a major potential interaction with Altered Consciousness.
Barbiturates should not be administered by injection to patients in shock or coma or who have recently received another respiratory depressant. The hypnotic and hypotensive effects of these agents may be prolonged and intensified in such patients.
Arrhythmia
Moderate:
Antispasmodic
The atropine, hyoscyamine and scopolamine in Antispasmodic all have a moderate potential interaction with Arrhythmia.
Antimuscarinic agents block vagal inhibition of the SA nodal pacemaker. These agents should be administered cautiously in patients with tachycardia, congestive heart failure, or coronary artery disease. Premature ventricular depolarization or ventricular tachycardia or fibrillation associated with antimuscarinic drugs is rare.
Moderate:
Antispasmodic
The atropine, hyoscyamine and scopolamine in Antispasmodic all have a moderate potential interaction with Arrhythmia.
Anticholinergics block vagal inhibition of the SA nodal pacemaker. Therapy with anticholinergics should be administered cautiously in patients with tachycardia, congestive heart failure, or coronary artery disease. Premature ventricular depolarization or ventricular tachycardia or fibrillation associated with anticholinergics is rare.
Asphyxia
Major:
Antispasmodic
The PHENobarbital in Antispasmodic has a major potential interaction with Asphyxia.
Barbiturates may produce severe respiratory depression, apnea, laryngospasm, bronchospasm and cough, particularly during rapid intravenous administration. In usual hypnotic dosages, the degree of respiratory depression produced is similar to that which occurs during physiologic sleep, while at higher dosages, the rate, depth and volume of respiration may be markedly decreased. However, some patients may be susceptible at commonly used dosages, including the elderly, debilitated or severely ill patients, those receiving other CNS depressants, and those with limited ventilatory reserve, chronic pulmonary insufficiency or other respiratory disorders. Therapy with barbiturates should be administered cautiously in these patients. Appropriate monitoring and individualization of dosage are particularly important, and equipment for resuscitation should be immediately available if the parenteral route is used. Barbiturates, especially injectable formulations, should generally be avoided in patients with sleep apnea, hypoxia, or severe pulmonary diseases in which dyspnea or obstruction is evident.
Asthma
Major:
Antispasmodic
The atropine, hyoscyamine and scopolamine in Antispasmodic all have a major potential interaction with Asthma.
The use of systemic anticholinergics is contraindicated in the treatment of lower respiratory tract symptoms including asthma. Muscarinic receptor antagonists reduce bronchial secretions, which can result in decreased fluidity and increased thickening of secretions. However, ipratropium does not produce these effects and can be used safely in treating asthma.
Autonomic Neuropathy
Major:
Antispasmodic
The atropine, hyoscyamine and scopolamine in Antispasmodic all have a major potential interaction with Autonomic Neuropathy.
Agents with anticholinergic activity can exacerbate many of the manifestations of autonomic neuropathy, including tachycardia, anhidrosis, bladder atony, obstipation, dry mouth and eyes, cycloplegia and blurring of vision, and sexual impotence in males. Therapy with antimuscarinic agents and higher dosages of antispasmodic agents (e.g., dicyclomine or oxybutynin) should be administered cautiously in patients with autonomic neuropathy.
Bleeding Disorder
Moderate:
Antispasmodic
The atropine, hyoscyamine and scopolamine in Antispasmodic all have a moderate potential interaction with Bleeding Disorder.
Antimuscarinic agents may cause a delay in gastric emptying and possibly antral stasis in patients with gastric ulcer. Therapy with antimuscarinic agents should be administered cautiously to patients with gastric ulcer.
Bone Marrow Depression/Low Blood Counts
Moderate:
Antispasmodic
The PHENobarbital in Antispasmodic has a moderate potential interaction with Bone Marrow Depression/Low Blood Counts.
Hematologic toxicity, including agranulocytosis, thrombocytopenic purpura and megaloblastic anemia, has been reported rarely during use of barbiturates. Therapy with barbiturates should be administered cautiously in patients with preexisting blood dyscrasias or bone marrow suppression. Blood counts are recommended prior to and periodically during long-term therapy, and patients should be instructed to immediately report any signs or symptoms suggestive of blood dyscrasia such as fever, sore throat, local infection, easy bruising, petechiae, bleeding, pallor, dizziness, or jaundice. Barbiturate therapy should be discontinued if blood dyscrasias occur.
Cardiovascular Conditions and Disorders
Moderate:
Antispasmodic
The atropine, hyoscyamine and scopolamine in Antispasmodic all have a moderate potential interaction with Cardiovascular Conditions and Disorders.
Anticholinergics block vagal inhibition of the SA nodal pacemaker. Therapy with anticholinergics should be administered cautiously to patients with tachycardia, congestive heart failure, or coronary artery disease. Premature ventricular depolarization, ventricular tachycardia, and fibrillation associated with anticholinergics are rare.
Depression
Moderate:
Antispasmodic
The PHENobarbital in Antispasmodic has a moderate potential interaction with Depression.
Barbiturates depress the central nervous system and may cause or exacerbate mental depression. Therapy with barbiturates should be administered cautiously in patients with a history of depression or suicidal tendencies. It may be prudent to refrain from dispensing large quantities of medication to these patients.
Moderate:
Antispasmodic
The PHENobarbital in Antispasmodic has a moderate potential interaction with Depression.
Antiepileptic drugs (AEDs) have been associated with an increased risk of suicidal thoughts or behavior in patients taking these drugs for any indication. Pooled analyses of 199 placebo-controlled clinical studies involving the use of 11 different AEDs showed that patients receiving AEDs had approximately twice the risk of suicidal thinking or behavior compared to patients receiving placebo. AEDs should be administered cautiously in patients with depression or other psychiatric disorders; phentermine-topiramate should be avoided in patients with history of suicidal attempts or active suicidal ideation. The risk of suicidal thoughts and behavior should be carefully assessed against the risk of untreated illness, bearing in mind that epilepsy and many other conditions for which AEDs are prescribed are themselves associated with morbidity and mortality and an increased risk of suicidal thoughts and behavior. Patients, caregivers, and families should be alert to the emergence or worsening of signs and symptoms of depression, any unusual changes in mood or behavior, or the emergence of suicidal thoughts or behavior. If patients have symptoms of suicidal ideation or behavior, a dosage reduction or treatment discontinuation should be considered.
Dermatitis, Drug-Induced
Major:
Antispasmodic
The PHENobarbital in Antispasmodic has a major potential interaction with Dermatitis, Drug-Induced.
Skin eruptions may precede rare but potentially fatal barbiturate-induced reactions such as systemic lupus erythematosus and exfoliative dermatitis, the latter of which may be accompanied by hepatitis and jaundice. Therapy with barbiturates should be administered cautiously in patients with preexisting drug-induced dermatitis, since it may delay the recognition of a potential reaction to barbiturates. Barbiturate therapy should be withdrawn promptly at the first sign of a dermatologic adverse effect. However, cutaneous reactions may proceed to an irreversible stage even after cessation of medication due to the slow rate of metabolism and excretion of barbiturates. Patients should be advised to promptly report signs that may indicate impending development of barbiturate-related cutaneous lesions, including high fever, severe headache, stomatitis, conjunctivitis, rhinitis, urethritis, and balanitis. Rashes may be more likely to occur with phenobarbital and mephobarbital.
Diarrhea
Minor:
Antispasmodic
The atropine, hyoscyamine and scopolamine in Antispasmodic all have a minor potential interaction with Diarrhea.
Diarrhea may be a symptom of incomplete intestinal obstruction, especially in patients with ileostomy or colostomy. Antimuscarinic agents may further aggravate the diarrhea. Therefore, these drugs should be administered cautiously in patients with diarrhea.
Drug Dependence
Major:
Antispasmodic
The PHENobarbital in Antispasmodic has a major potential interaction with Drug Dependence.
Barbiturates have the potential to cause dependence and abuse. Tolerance as well as physical and psychological dependence can develop, particularly after prolonged use of excessive dosages. Abrupt cessation and/or a reduction in dosage may precipitate withdrawal symptoms. In patients who have developed tolerance to a barbiturate, overdosage can still produce respiratory depression and death, and cross-tolerance usually will occur with other agents in the class. Addiction-prone individuals, such as those with a history of alcohol or substance abuse, should be under careful surveillance or medical supervision when treated with barbiturates. It may be prudent to refrain from dispensing large quantities of medication to these patients. After prolonged use or if dependency is suspected, withdrawal of barbiturates should be undertaken gradually using a dosage-tapering schedule.
Esophageal Obstruction
Major:
Antispasmodic
The atropine, hyoscyamine and scopolamine in Antispasmodic all have a major potential interaction with Esophageal Obstruction.
Anticholinergics are contraindicated in patients with obstructive diseases such as achalasia, esophageal stricture or stenosis, pyloroduodenal stenosis, stenosing peptic ulcer, pyloric obstruction, and paralytic ileus. Anticholinergics may further suppress intestinal motility with resultant precipitation or aggravation of toxic megacolon.
Fever
Minor:
Antispasmodic
The atropine, hyoscyamine and scopolamine in Antispasmodic all have a minor potential interaction with Fever.
Atropine-like agents may increase the risk of hyperthermia in patients with fever by producing anhidrosis. Therapy with atropine-like agents should be administered cautiously in febrile patients.
Gastrointestinal Obstruction
Major:
Antispasmodic
The atropine, hyoscyamine and scopolamine in Antispasmodic all have a major potential interaction with Gastrointestinal Obstruction.
Anticholinergics are contraindicated in patients with obstructive diseases such as achalasia, esophageal stricture or stenosis, pyloroduodenal stenosis, stenosing peptic ulcer, pyloric obstruction, and paralytic ileus. Anticholinergics may further suppress intestinal motility with resultant precipitation or aggravation of toxic megacolon.
GERD
Moderate:
Antispasmodic
The atropine, hyoscyamine and scopolamine in Antispasmodic all have a moderate potential interaction with GERD.
Antimuscarinic agents decrease gastric motility and relax the lower esophageal sphincter which promotes gastric retention and can aggravate reflux. These drugs should be administered cautiously in patients with gastroesophageal reflux or hiatal hernia associated with reflux esophagitis.
Glaucoma/Intraocular Hypertension
Major:
Antispasmodic
The atropine, hyoscyamine and scopolamine in Antispasmodic all have a major potential interaction with Glaucoma/Intraocular Hypertension.
Anticholinergic agents are contraindicated in patients with primary glaucoma, a tendency toward glaucoma (narrow anterior chamber angle), or adhesions (synechiae) between the iris and lens, as well as for the elderly and others in whom undiagnosed glaucoma or excessive pressure in the eye may be present. Because anticholinergics cause mydriasis, they may exacerbate these conditions.
Heart Disease
Major:
Antispasmodic
The PHENobarbital in Antispasmodic has a major potential interaction with Heart Disease.
The intravenous administration of barbiturates may produce severe cardiovascular reactions such as bradycardia, hypertension, or vasodilation with fall in blood pressure, particularly during rapid infusion. Parenteral therapy with barbiturates should be administered cautiously in patients with hypertension, hypotension, or cardiac disease. The intravenous administration of barbiturates should be reserved for emergency treatment of acute seizures or for anesthesia.
High Blood Pressure
Major:
Antispasmodic
The PHENobarbital in Antispasmodic has a major potential interaction with High Blood Pressure.
The intravenous administration of barbiturates may produce severe cardiovascular reactions such as bradycardia, hypertension, or vasodilation with fall in blood pressure, particularly during rapid infusion. Parenteral therapy with barbiturates should be administered cautiously in patients with hypertension, hypotension, or cardiac disease. The intravenous administration of barbiturates should be reserved for emergency treatment of acute seizures or for anesthesia.
Minor:

High Cholesterol
Moderate:
rilonacept
Rilonacept has a moderate potential interaction with High Cholesterol.
Patients treated with rilonacept experienced increases in their mean total cholesterol, HDL cholesterol, LDL cholesterol, and triglycerides. The mean increases from baseline for total cholesterol, HDL cholesterol, LDL cholesterol, and triglycerides were 19 mg/dL, 2 mg/dL, 10 mg/dL, and 57 mg/dL respectively after 6 weeks of open-label therapy. Physicians should monitor the lipid profiles of their patients especially those with hyperlipidemias, and consider lipid-lowering therapies as needed based upon cardiovascular risk factors and current guidelines.
Hyperkinetic Syndrome of Childhood
Moderate:
Antispasmodic
The PHENobarbital in Antispasmodic has a moderate potential interaction with Hyperkinetic Syndrome of Childhood.
Paradoxical reactions characterized by excitability and restlessness may occur in pediatric patients with hyperactive aggressive disorders. Such patients should be monitored for signs of paradoxical stimulation during therapy with barbiturates.
Hyperthyroidism
Minor:
Antispasmodic
The atropine, hyoscyamine and scopolamine in Antispasmodic all have a minor potential interaction with Hyperthyroidism.
In general, agents with anticholinergic activity may exacerbate hyperthyroidism. Therapy with anticholinergics should be administered cautiously in patients with hyperthyroidism. Thyroid levels should be monitored if usage is prolonged.
Hypotension
Major:
Antispasmodic
The PHENobarbital in Antispasmodic has a major potential interaction with Hypotension.
The intravenous administration of barbiturates may produce severe cardiovascular reactions such as bradycardia, hypertension, or vasodilation with fall in blood pressure, particularly during rapid infusion. Parenteral therapy with barbiturates should be administered cautiously in patients with hypertension, hypotension, or cardiac disease. The intravenous administration of barbiturates should be reserved for emergency treatment of acute seizures or for anesthesia.
Infection
Moderate:
rilonacept
Rilonacept has a moderate potential interaction with Infection.
Interleukin-1 (IL-1) blockade may interfere with the immune response to infections. Treatment with other medication as rilonacept, that work through inhibition of IL-1 has been associated with an increased risk of serious infections, and serious infections have been reported in patients taking rilonacept compared with placebo. Rilonacept should be discontinued if a patient develops a serious infection. Treatment with rilonacept should not be initiated in patients with an active or chronic infection. Additionally, latent tuberculosis can be reactivated and should be treated before initiating therapy with rilonacept.
Infectious Gastroenteritis
Major:
Antispasmodic
The atropine, hyoscyamine and scopolamine in Antispasmodic all have a major potential interaction with Infectious Gastroenteritis.
The use of drugs with antiperistaltic activity (primarily antidiarrheal and antimuscarinic agents, but also antispasmodic agents such as dicyclomine or oxybutynin at high dosages) is contraindicated in patients with diarrhea due to pseudomembranous enterocolitis or enterotoxin-producing bacteria. These drugs may prolong and/or worsen diarrhea associated with organisms that invade the intestinal mucosa, such as toxigenic E. coli, Salmonella and Shigella, and pseudomembranous colitis due to broad-spectrum antibiotics. Other symptoms and complications such as fever, shedding of organisms and extraintestinal illness may also be increased or prolonged. In general, because antiperistaltic agents decrease gastrointestinal motility, they may delay the excretion of infective gastroenteric organisms or toxins and should be used cautiously in patients with any infectious diarrhea, particularly if accompanied by high fever or pus or blood in the stool. Some cough and cold and other combination products may occasionally include antimuscarinic agents for their drying effects and may, therefore, require careful selection when necessary.
Ischemic Heart Disease
Moderate:
Antispasmodic
The atropine, hyoscyamine and scopolamine in Antispasmodic all have a moderate potential interaction with Ischemic Heart Disease.
Antimuscarinic agents block vagal inhibition of the SA nodal pacemaker. These agents should be administered cautiously in patients with tachycardia, congestive heart failure, or coronary artery disease. Premature ventricular depolarization or ventricular tachycardia or fibrillation associated with antimuscarinic drugs is rare.
Liver Disease
Major:
Antispasmodic
The PHENobarbital in Antispasmodic has a major potential interaction with Liver Disease.
Barbiturates are extensively metabolized by the liver. The plasma clearance of barbiturates may be decreased and the half-lives prolonged in patients with impaired hepatic function. Therapy with barbiturates should be administered cautiously and initiated at reduced dosages in patients with liver disease. Barbiturates are not recommended for use in patients with cirrhosis, hepatic failure, hepatic coma, or other severe hepatic impairment.
Moderate:
Antispasmodic
The atropine and hyoscyamine in Antispasmodic both have a moderate potential interaction with Liver Disease.
Atropine-like agents undergo significant hepatic metabolism. Therapy with atropine-like agents should be administered cautiously to patients with liver disease.
Moderate:
rilonacept
Rilonacept has a moderate potential interaction with Liver Disease.
No formal studies have been conducted to examine the pharmacokinetics of rilonacept administered subcutaneously in patients with hepatic impairment. Caution is advised if used on these patients.
Myasthenia Gravis
Major:
Antispasmodic
The atropine, hyoscyamine and scopolamine in Antispasmodic all have a major potential interaction with Myasthenia Gravis.
Because antimuscarinic agents have anticholinergic effects, they are contraindicated in patients with myasthenia gravis. Their use may be appropriate to reduce adverse muscarinic effects caused by an anticholinesterase agent.
Panhypopituitarism
Moderate:
Antispasmodic
The PHENobarbital in Antispasmodic has a moderate potential interaction with Panhypopituitarism.
Barbiturates, especially phenobarbital, secobarbital and butabarbital, may diminish the systemic effects of exogenous and endogenous corticosteroids via induction of hepatic microsomal enzymes, thereby accelerating the metabolism of corticosteroids. In addition, barbiturates may interfere with pituitary corticotropin production. Therapy with barbiturates should be administered cautiously in patients with adrenal insufficiency. Patients with borderline hypoadrenalism should be monitored closely, and patients receiving steroid supplementation may require an adjustment in dosage when barbiturates are added to or withdrawn from their medication regimen.
Porphyria
Major:
Antispasmodic
The PHENobarbital in Antispasmodic has a major potential interaction with Porphyria.
The use of barbiturates is contraindicated in patients with a history of porphyria. Barbiturates may exacerbate acute intermittent porphyria or porphyria variegata by inducing the enzymes responsible for porphyrin synthesis.
Psychosis
Moderate:
Antispasmodic
The PHENobarbital in Antispasmodic has a moderate potential interaction with Psychosis.
Antiepileptic drugs (AEDs) have been associated with an increased risk of suicidal thoughts or behavior in patients taking these drugs for any indication. Pooled analyses of 199 placebo-controlled clinical studies involving the use of 11 different AEDs showed that patients receiving AEDs had approximately twice the risk of suicidal thinking or behavior compared to patients receiving placebo. AEDs should be administered cautiously in patients with depression or other psychiatric disorders; phentermine-topiramate should be avoided in patients with history of suicidal attempts or active suicidal ideation. The risk of suicidal thoughts and behavior should be carefully assessed against the risk of untreated illness, bearing in mind that epilepsy and many other conditions for which AEDs are prescribed are themselves associated with morbidity and mortality and an increased risk of suicidal thoughts and behavior. Patients, caregivers, and families should be alert to the emergence or worsening of signs and symptoms of depression, any unusual changes in mood or behavior, or the emergence of suicidal thoughts or behavior. If patients have symptoms of suicidal ideation or behavior, a dosage reduction or treatment discontinuation should be considered.
Pulmonary Impairment
Major:
Antispasmodic
The PHENobarbital in Antispasmodic has a major potential interaction with Pulmonary Impairment.
Barbiturates may produce severe respiratory depression, apnea, laryngospasm, bronchospasm and cough, particularly during rapid intravenous administration. In usual hypnotic dosages, the degree of respiratory depression produced is similar to that which occurs during physiologic sleep, while at higher dosages, the rate, depth and volume of respiration may be markedly decreased. However, some patients may be susceptible at commonly used dosages, including the elderly, debilitated or severely ill patients, those receiving other CNS depressants, and those with limited ventilatory reserve, chronic pulmonary insufficiency or other respiratory disorders. Therapy with barbiturates should be administered cautiously in these patients. Appropriate monitoring and individualization of dosage are particularly important, and equipment for resuscitation should be immediately available if the parenteral route is used. Barbiturates, especially injectable formulations, should generally be avoided in patients with sleep apnea, hypoxia, or severe pulmonary diseases in which dyspnea or obstruction is evident.
Renal Dysfunction
Major:
Antispasmodic
The PHENobarbital in Antispasmodic has a major potential interaction with Renal Dysfunction.
The long-acting barbiturate, phenobarbital, is partially eliminated by the kidney. The plasma clearance of phenobarbital may be decreased and the half-life prolonged in patients with impaired renal function. Therapy with phenobarbital should be administered cautiously and initiated at reduced dosages in patients with renal impairment. Since approximately 75% of a mephobarbital dose is metabolized to phenobarbital, the same precaution should be observed with mephobarbital. The remaining barbiturates, which are short- and intermediate-acting, are all negligibly excreted in the urine and may be appropriate alternatives in these patients.
Moderate:
Antispasmodic
The atropine and hyoscyamine in Antispasmodic both have a moderate potential interaction with Renal Dysfunction.
Atropine-like agents are primarily eliminated by the kidney. Therapy with atropine-like agents should be administered cautiously to patients with renal disease.

Interleukin-1 (IL-1) blockade may interfere with the immune response to infections. Treatment with other medication as rilonacept, that work through inhibition of IL-1 has been associated with an increased risk of serious infections, and serious infections have been reported in patients taking rilonacept compared with placebo. Rilonacept should be discontinued if a patient develops a serious infection. Treatment with rilonacept should not be initiated in patients with an active or chronic infection. Additionally, latent tuberculosis can be reactivated and should be treated before initiating therapy with rilonacept.
Ulcerative Colitis
Moderate:
Antispasmodic
The atropine, hyoscyamine and scopolamine in Antispasmodic all have a moderate potential interaction with Ulcerative Colitis.
Antimuscarinic agents may suppress intestinal motility and produce paralytic ileus with resultant precipitation of toxic megacolon. These drugs should be administered cautiously to patients with ulcerative colitis.
Urinary Retention
Major:
Antispasmodic
The atropine, hyoscyamine and scopolamine in Antispasmodic all have a major potential interaction with Urinary Retention.
In general, the use of anticholinergic agents is contraindicated in patients with urinary retention and bladder neck obstruction caused by prostatic hypertrophy. Dysuria may occur and may require catheterization. Also, anticholinergic drugs may aggravate partial obstructive uropathy. Caution is advised even when using agents with mild to moderate anticholinergic activity, particularly in elderly patients.
Vaccination
Major:
rilonacept
Rilonacept has a major potential interaction with Vaccination.
Live vaccines should not be given concurrently with rilonacept. Rilonacept may interfere with normal immune response to new antigens; therefore, vaccinations may not be effective in patients receiving rilonacept. No data are available on the effectiveness of vaccination with inactivated (killed) antigens in patients receiving rilonacept. Because IL-1 blockade may interfere with immune response to infections, it is recommended that prior to initiation of therapy with rilonacept adult and pediatric patients receive all recommended vaccinations, as appropriate, including pneumococcal vaccine and inactivated influenza vaccine.
Vitamin D Deficiency
Moderate:
Antispasmodic
The PHENobarbital in Antispasmodic has a moderate potential interaction with Vitamin D Deficiency.
Rickets and osteomalacia have rarely been reported following prolonged use of barbiturates, possibly due to increased metabolism of vitamin D as a result of enzyme induction by barbiturates. Long-term therapy with barbiturates should be administered cautiously in patients with vitamin D deficiency.
