Mebendazole will no longer be available in the U.S. after October 2011. If you are currently taking mebendazole, you should talk to your doctor to discuss switching to another treatment.
Mebendazole, an antiworm medication, kills parasites. It is used to treat roundworm, hookworm, pinworm, whipworm, and other worm infections.
This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.
Mebendazole comes as a chewable tablet. It usually is taken twice a day, in the morning and evening, for 3 days or as a single (one-time) dose. You may chew the tablets, swallow them whole, or crush and mix them with food. Treatment may have to be repeated in 2-3 weeks. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take mebendazole exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Before taking mebendazole,
- tell your doctor and pharmacist if you are allergic to mebendazole or any other drugs.
- tell your doctor and pharmacist what prescription and nonprescription medications you are taking, especially carbamazepine (Tegretol), phenytoin (Dilantin), and vitamins.
- tell your doctor if you have or have ever had stomach or liver disease.
- tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking mebendazole, call your doctor.
Take the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.
Mebendazole may cause side effects. Tell your doctor if any of these symptoms are severe or do not go away:
Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom). Throw away any medication that is outdated or no longer needed. Talk to your pharmacist about the proper disposal of your medication.
In case of overdose, call your local poison control center at 1-800-222-1222. If the victim has collapsed or is not breathing, call local emergency services at 911.
Keep all appointments with your doctor and the laboratory. Your doctor will order certain lab tests to check your response to mebendazole.
Do not let anyone else take your medication. Your prescription is probably not refillable. If you still have symptoms of infection after you finish the mebendazole, call your doctor.
It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
