Interactions between your drugs

Moderate

procainamide adefovir

Applies to: procainamide and adefovir

MONITOR: Theoretically, coadministration of adefovir dipivoxil with other drugs that are eliminated by active tubular secretion may result in increased plasma concentrations of adefovir and/or the coadministered drug(s). The mechanism is competitive inhibition of renal excretion. Drugs that are thought to undergo active tubular secretion include metformin, cimetidine, ranitidine, procainamide, flecainide, quinidine, triamterene, midodrine, cidofovir, acyclovir, valacyclovir, tenofovir, ganciclovir, and valganciclovir.

MANAGEMENT: Patients receiving adefovir dipivoxil in combination with other drugs that undergo active tubular secretion should be monitored for excessive pharmacologic effects of one or both drugs, and the dosages of the drugs adjusted if necessary.

Drug and food interactions

Minor

procainamide food

Applies to: procainamide

Ethanol may increase the acetylation of procainamide. Subtherapeutic plasma levels of procainamide may result in some patients. Because the acetylated metabolite of procainamide also possesses antiarrhythmic properties, the clinical effects are unclear.

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.
