Mebendazole is available by prescription only. It is a chewable tablet given in two doses about two weeks apart. The second treatment is needed to kill any pinworms that have hatched after the first treatment.
How It Works
Mebendazole kills both immature worms and adult pinworms over a period of 2 to 3 days. It does not kill pinworm eggs.
Why It Is Used
Mebendazole is used to treat pinworm infections. It may also be used when infection persists after using pyrantel pamoate (a nonprescription medication).
Mebendazole should not be taken by pregnant women, breast-feeding women, or children younger than 2 years of age.
How Well It Works
Mebendazole is highly effective and cures pinworm infections more than 90% of the time.1
Side Effects

- Diarrhea.
- Abdominal pain.
See Drug Reference for a full list of side effects. (Drug Reference is not available in all systems.)
What To Think About
