Pyrantel Pamoate for the Treatment of Pinworms
Pyrantel pamoate treats pinworm infections. The dose of pyrantel pamoate given is based on the person's weight.
Pyrantel pamoate comes as a liquid or a chewable pill. Some brands come with a small measuring cup and a weight chart on the box so that you can calculate correct doses. If you have problems calculating a dose or have concerns about the medicine, talk with a pharmacist or your doctor.
How It Works
Pyrantel pamoate kills adult pinworms. It does not kill pinworm eggs.
Why It Is Used
Pyrantel pamoate is an over-the-counter medicine commonly used for pinworm infections. It is taken after a definite diagnosis of pinworms has been made by either seeing the worms or doing a transparent (cellophane) tape test. Your doctor may also suggest it if other pinworm medicines haven't worked.
How Well It Works
Pyrantel pamoate gets rid of pinworm infections most of the time. But reinfection with pinworms is very common.
All medicines have side effects. But many people don't feel the side effects, or they are able to deal with them. Ask your pharmacist about the side effects of each medicine you take. Side effects are also listed in the information that comes with your medicine.

There are many reasons why people have trouble taking their medicine. But in most cases, there is something you can do. For suggestions on how to work around common problems, see the topic Taking Medicines as Prescribed.
Advice for women
If you are pregnant, breast-feeding, or planning to get pregnant, do not use any medicines unless your doctor tells you to. Some medicines can harm your baby. This includes prescription and over-the-counter medicines, vitamins, herbs, and supplements. And make sure that all your doctors know that you are pregnant, breast-feeding, or planning to get pregnant.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
