Pyrantel: MedlinePlus Drug Information

T Why is this medication prescribed?
P Pyrantel, an antiworm medication, is used to treat roundworm, hookworm, pinworm, and other worm infections.
P This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

T How should this medicine be used?
P Pyrantel comes as a capsule and a liquid to take by mouth. It usually is taken as a single dose for pinworm and roundworm infections. The dose usually is repeated after 2 weeks for pinworm infections. For hookworm infections, pyrantel usually is taken once a day for 3 days. Pyrantel may be taken with food, juice, or milk or on an empty stomach.
P Shake the liquid well to mix the medication evenly. Pyrantel may be mixed with milk or fruit juice. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take pyrantel exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

T What special precautions should I follow?
t Before taking pyrantel,
- tell your doctor and pharmacist if you are allergic to pyrantel or any other drugs.
- tell your doctor and pharmacist what prescription and nonprescription medications you are taking, especially piperazine (another antiworm medication), and vitamins.
- tell your doctor if you have or have ever had anemia or liver disease.
- tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking pyrantel, call your doctor.

T What should I do if I forget a dose?
P 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.

T What side effects can this medication cause?
t Pyrantel may cause side effects. Tell your doctor if any of these symptoms are severe or do not go away:
- upset stomach
- vomiting
- diarrhea
- loss of appetite
- stomach cramps
- stomach pain
- straining and pain during bowel movements

T What should I know about storage and disposal of this medication?
P 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).
P It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
P Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.

T What other information should I know?
P Keep all appointments with your doctor and the laboratory. Your doctor will order certain lab tests to check your response to pyrantel.
P 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 pyrantel, call your doctor.
P 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.
