Interactions between your drugs

Moderate

ibuprofen pitolisant

Applies to: Motrin PM (diphenhydramine / ibuprofen) and pitolisant

MONITOR: Concomitant use of pitolisant with NSAIDs and/or corticosteroids may increase the risk of gastrointestinal adverse effects such as dyspepsia, abdominal pain or discomfort, and gastritis due to potential additive irritant effects on the gastrointestinal mucosa. Clinical studies with pitolisant reported gastric disorders caused by hyperacidity in 3.5% of patients. However, the effects were described as mostly mild to moderate in severity. Data are not available on the potential for serious gastrointestinal (GI) toxicity, including inflammation, bleeding, ulceration, and perforation.

MANAGEMENT: Caution is advised if pitolisant is used in combination with NSAIDs and/or corticosteroids, particularly in patients with a prior history of peptic ulcer disease or GI bleeding and in elderly or debilitated patients. If concomitant therapy is required, patients should be advised to report signs and symptoms of adverse GI effects, including abdominal pain or discomfort, dyspepsia, gastroesophageal reflux disease, gastritis, or the appearance of black, tarry stools.

Moderate

diphenhydrAMINE pitolisant

Applies to: Motrin PM (diphenhydramine / ibuprofen) and pitolisant

GENERALLY AVOID: Because pitolisant enhances the activity of histaminergic neurons in the brain, centrally acting histamine H1-receptor antagonists or medicines with H1-receptor antagonist properties (e.g., tri- and tetracyclic antidepressants) may impair the efficacy of pitolisant.

MANAGEMENT: According to the manufacturer, coadministration of pitolisant with centrally acting H1-receptor antagonists or tri- and tetracyclic antidepressants should be avoided.

Drug and food interactions

Moderate

ibuprofen food

Applies to: Motrin PM (diphenhydramine / ibuprofen)

GENERALLY AVOID: The concurrent use of aspirin or nonsteroidal anti-inflammatory drugs (NSAIDs) and ethanol may lead to gastrointestinal (GI) blood loss. The mechanism may be due to a combined local effect as well as inhibition of prostaglandins leading to decreased integrity of the GI lining.

MANAGEMENT: Patients should be counseled on this potential interaction and advised to refrain from alcohol consumption while taking aspirin or NSAIDs.

Moderate

diphenhydrAMINE food

Applies to: Motrin PM (diphenhydramine / ibuprofen)

GENERALLY AVOID: Use of anticholinergic agents with alcohol may result in sufficient impairment of attention so as to render driving and operating machinery more hazardous. In addition, the potential for abuse may be increased with the combination. The mechanism of interaction is not established but may involve additive depressant effects on the central nervous system. No effect of oral propantheline or atropine on blood alcohol levels was observed in healthy volunteers when administered before ingestion of a standard ethanol load. However, one study found impairment of attention in subjects given atropine 0.5 mg or glycopyrrolate 1 mg in combination with alcohol.

MANAGEMENT: Alcohol should generally be avoided during therapy with anticholinergic agents. Patients should be counseled to avoid activities requiring mental alertness until they know how these agents affect them.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
