Interactions between your drugs

Moderate

chloramphenicol otic tenofovir

Applies to: chloramphenicol otic and AccessPak for HIV PEP Basic (emtricitabine / tenofovir disoproxil)

GENERALLY AVOID: Coadministration of topical chloramphenicol with other agents that can cause bone marrow depression, aplastic anemia, or agranulocytosis may increase the risk and/or severity of hematologic toxicity. Chloramphenicol may be absorbed systemically from the eye, ear, and vagina. Bone marrow hypoplasia, including aplastic anemia and death, has been reported following topical use of chloramphenicol. However, systemic absorption following topical, ophthalmic, otic, and vaginal administration is generally minimal, and data concerning the incidence of blood dyscrasias following the use of topical chloramphenicol are not available.

MANAGEMENT: Concurrent use of topical chloramphenicol formulations with other bone marrow depressing agents should generally be avoided. If concomitant use on a long-term or intermittent basis is considered necessary, patients should be monitored for the development of hematologic adverse effects. Monitoring via full blood counts before and periodically during therapy may also be advisable.

Drug and food interactions

Minor

tenofovir food

Applies to: AccessPak for HIV PEP Basic (emtricitabine / 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.
