Therefore, before using clarithromycin, report all medications you are currently using to your doctor or pharmacist.Before using this medication, tell your doctor or pharmacist of all prescription and nonprescription/herbal products you may use, especially of: drugs affecting liver enzymes that remove clarithromycin from your body (such as rifamycins - including rifabutin and rifampin, and azole antifungals - including itraconazole and fluconazole), certain HIV medications (e.g., zidovudine, delavirdine, protease inhibitors such as atazanavir, ritonavir), certain anti-seizure medications (e.g., carbamazepine, phenytoin, valproate), "blood thinners" (e.g., warfarin), colchicine, digoxin, live bacterial vaccines.This drug can slow down the removal of other drugs from your body by affecting certain liver enzymes.
