- Changes in gastric pH may affect the bioavailability of some medicines (e.g., reduced absorption of atazanavir (an antiviral medicine used to treat HIV infection)).
- Famotidine may reduce the absorption of ketoconazole and itraconazole (antifungal medicines). Ketoconazole should be administered 2 hours before famotidine.
- Antacids may reduce the absorption of famotidine and lead to decreased serum famotidine concentrations. Therefore, famotidine should be taken 1-2 hours before antacids.
- Concomitant administration of probenecid (a medicine used to treat gout) may delay the elimination of famotidine. Concomitant administration of famotidine and probenecid should be avoided.
- Concomitant administration of sucralfate (a protective medicine used to treat stomach ulcers) within 2 hours after famotidine administration should be avoided.
- There is a risk of reduced efficacy of calcium carbonate, used in dialyzed patients as a phosphate binder, if administered concomitantly with famotidine.
- The use of Famiflux may reduce the effect of posaconazole in oral suspension (an antifungal medicine used to prevent and treat certain fungal infections).
- The use of Famiflux may reduce the effect of dasatinib, erlotinib, gefitinib, pazopanib (medicines used to treat cancer).
- Famotidine may reduce the absorption of the following compounds:
