Interactions between your drugs

Moderate

clindamycin nelfinavir

Applies to: clindamycin and emtricitabine / nelfinavir / tenofovir disoproxil

MONITOR: Coadministration with strong CYP450 3A4 inhibitors may increase plasma concentrations and the risk of adverse effects of clindamycin, which is metabolized predominantly by the isoenzyme.

MANAGEMENT: Caution is advised if clindamycin is used concomitantly with strong CYP450 3A4 inhibitors. The possibility of adverse reactions to clindamycin should be considered during coadministration with strong CYP450 3A4 inhibitors. Dosage adjustments as well as clinical and laboratory monitoring of clindamycin should be considered whenever a strong CYP450 3A4 inhibitor is added to or withdrawn from therapy.

Drug and food interactions

Minor

tenofovir food

Applies to: emtricitabine / nelfinavir / tenofovir disoproxil

Food enhances the oral absorption and bioavailability of tenofovir, the active entity of tenofovir disoproxil fumarate. According to the product labeling, administration of the drug following a high-fat meal increased the mean peak plasma concentration (Cmax) and area under the concentration-time curve (AUC) of tenofovir by approximately 14% and 40%, respectively, compared to administration in the fasting state. However, administration with a light meal did not significantly affect the pharmacokinetics of tenofovir compared to administration in the fasting state. Food delays the time to reach tenofovir Cmax by approximately 1 hour. Tenofovir disoproxil fumarate may be administered without regard to meals.

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.
