Interactions between your drugs

Moderate

diphenhydrAMINE ropeginterferon alfa-2b

Applies to: Vanamine PD (diphenhydramine) and ropeginterferon alfa-2b

GENERALLY AVOID: Coadministration with narcotics, hypnotics, or sedatives may potentiate the neuropsychiatric side effects of ropeginterferon alfa-2b. Serious and life-threatening or fatal neuropsychiatric reactions have been reported in patients receiving interferon alfa products, including ropeginterferon alfa-2b. These reactions may occur in patients with or without previous psychiatric illness. Serious neuropsychiatric reactions were observed in 3% of patients treated with ropeginterferon alfa-2b during the clinical development program. In two open label trials consisting of 178 patients receiving ropeginterferon alfa-2b monotherapy (dosed every 2 to 4 weeks) for the treatment of polycythemia vera, 80% of whom were exposed for 12 months or longer, there were 17 reported cases of depression, depressive symptoms, depressed mood, and listlessness. Of these seventeen cases, 3.4% of the patients recovered with temporary treatment interruption and 2.8% discontinued treatment. Other central nervous system effects, including suicidal ideation, attempted suicide, aggression, bipolar disorder, mania and confusion, have been reported with other interferon alfa products.

MANAGEMENT: Concomitant use of ropeginterferon alfa-2b with narcotics, hypnotics, or sedatives should be avoided when possible. Otherwise, patients should be closely monitored for effects of excessive central nervous system toxicity and symptoms of psychiatric disorders. Consider psychiatric consultation and treatment if such symptoms emerge, and discontinuation of ropeginterferon alfa-2b in patients with persistently severe or worsening neuropsychiatric signs or symptoms.

Drug and food interactions

Moderate

diphenhydrAMINE food

Applies to: Vanamine PD (diphenhydramine)

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.
