Polycarbophil may interact with other medications if given at the same time. This can cause your other medications to become less effective. In general, all oral medications should be administered at least 2 hours before or 2 hours after dosing of polycarbophil.

Moderate

diphenhydrAMINE food

Applies to: Benadryl (diphenhydramine)

Ask your doctor before using diphenhydrAMINE together with ethanol (alcohol). Use alcohol cautiously. Alcohol may increase drowsiness and dizziness while you are taking diphenhydrAMINE. You should be warned not to exceed recommended dosages and to avoid activities requiring mental alertness. If your doctor prescribes these medications together, you may need a dose adjustment to safely take this combination. 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.
