Interactions between your drugs

Moderate

dihydrocodeine ropeginterferon alfa-2b

Applies to: acetaminophen / caffeine / dihydrocodeine 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

Major

acetaminophen food

Applies to: acetaminophen / caffeine / dihydrocodeine

GENERALLY AVOID: Chronic, excessive consumption of alcohol may increase the risk of acetaminophen-induced hepatotoxicity, which has included rare cases of fatal hepatitis and frank hepatic failure requiring liver transplantation. The proposed mechanism is induction of hepatic microsomal enzymes during chronic alcohol use, which may result in accelerated metabolism of acetaminophen and increased production of potentially hepatotoxic metabolites.

MANAGEMENT: In general, chronic alcoholics should avoid regular or excessive use of acetaminophen. Alternative analgesic/antipyretic therapy may be appropriate in patients who consume three or more alcoholic drinks per day. However, if acetaminophen is used, these patients should be cautioned not to exceed the recommended dosage (maximum 4 g/day in adults and children 12 years of age or older).

caffeine food

Applies to: acetaminophen / caffeine / dihydrocodeine

The effect of grapefruit juice on the pharmacologic activity of caffeine is controversial. One report suggests that grapefruit juice increases the effect of caffeine. The proposed mechanism is inhibition of cytochrome P-450 metabolism of caffeine. However, a well-conducted pharmacokinetic/pharmacodynamic study did not demonstrate this effect. The clinical significance of this potential interaction is unknown.

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.
