Generic Name
mebendazole

Mebendazole is available by prescription only. It is a chewable tablet given in two doses about 2 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 medicine).

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


Side effects are rare but may include:

  • 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


Children younger than age 2 should only take this medicine on the advice of a doctor.

Pregnant women and breast-feeding women should not take mebendazole without first consulting a doctor.
