What the FDA labels say about taking them together
Albendazole and cimetidine
Albendazole's FDA label of September 30, 2019 names cimetidine in its drug interactions section; the cimetidine label PlainMeds reads does not name albendazole. The albendazole label: “Albendazole sulfoxide concentrations in bile and cystic fluid were increased (about 2-fold) in hydatid cyst patients treated with cimetidine (10 mg/kg/day) (n = 7) compared with albendazole (20 mg/kg/day) alone (n = 12).”
