This medication is used to treat intestinal worm infections such as pinworm, roundworm, and hookworm. Pyrantel belongs to a class of drugs known as anthelmintics. It works by making the worms unable to move (paralyzed) so that the body can remove them naturally in the stool.
This medication may be used to self-treat pinworm infections. For other types of worm infections (such as roundworm, hookworm), use this product only as directed by your doctor. Do not use this medication in children younger than 2 years unless directed by the doctor.
If you are taking the over-the-counter product, read all directions on the product package before taking this medication. This medicine comes with a Patient Information Leaflet. Read it carefully. Be sure you understand how to identify pinworms, understand the symptoms of pinworm infections, and how to prevent becoming infected again. If you have any questions, consult your doctor or pharmacist.
Take this medication by mouth with or without food, usually once as a single dose or as directed by your doctor. If you are using the chewable tablets, chew each tablet well and swallow. This medication may be taken with milk or fruit juice. It is not necessary to take a laxative with this medication.
Dosage is based on your weight, type of infection, and response to treatment. Do not take more than a total of 1 gram in a single dose. If you are self-treating for pinworms, take the medication once only. Do not repeat the dose without talking with your doctor first. Depending on the type of worm infection you have, your doctor may direct you to take the medication only once or for several days. Your doctor may also direct you to repeat the dose in 2 weeks.
If you continue to see worms in your stool or if symptoms persist or worsen, or if you think you may have a different type of worm infection or a serious medical problem, seek immediate medical attention.
Nausea, vomiting, diarrhea, stomach/abdominal cramps, headache, drowsiness, dizziness, trouble sleeping, or loss of appetite may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.
