Generic Name: mebendazole

Medicines used to treat seizures, such as phenytoin (Dilantin), ethotoin (Peganone), mephenytoin (Mesantoin), and carbamazepine (Tegretol), may decrease the effects of mebendazole. Tell your doctor if you are taking any of these medications so that your therapy can be monitored.

Drugs other than those listed here may also interact with mebendazole. Talk to your doctor and pharmacist before taking any prescription or over-the-counter medicines, including vitamins, minerals, and herbal products.

Stop taking mebendazole and seek emergency medical attention if you experience an allergic reaction (swelling of your lips, tongue, or face; shortness of breath; closing of your throat; or hives).

Other, less serious side effects may be more likely to occur. Continue to take mebendazole and talk to your doctor if you experience abdominal pain, diarrhea, or a fever.

Side effects other than those listed here may also occur. Talk to your doctor about any side effect that seems unusual or that is especially bothersome.
