Relevance: 02.06.2023 Reviewer: Shkutko P.M., M.D., in

In the database of official manuals used in the service creation an interaction registered by statistical results of studies was found, which can either lead to negative consequences for the patient health or strengthen a mutual positive effect. A doctor should be consulted to address the issue of joint drug administration.

Consumer:

Ask your doctor before using ketoconazole together with famotidine. Using these medications together can make ketoconazole less effective. Let your doctor know if your condition worsens. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Professional:

ADJUST DOSE: H2 antagonists may reduce the bioavailability of ketoconazole by 75% to 80% resulting in decreased plasma ketoconazole concentrations and possible therapeutic failure. The mechanism is related to an increase in gastric pH and a decrease in absorption of the antifungal agent.

MANAGEMENT: Some manufacturers of ketoconazole suggest administering ketoconazole with an acidic beverage (e.g., non-diet cola, orange juice) if used concomitantly with H2 antagonists (US, GB, CA, BR). Dosage adjustments as well as clinical and laboratory monitoring should be considered whenever H2 antagonists are added to or withdrawn from therapy with ketoconazole.
