Praziquantel is used to treat schistosoma (infection with a type of worm that lives in the bloodstream) and liver fluke (infection with a type of worm that lives in or near the liver). Praziquantel is in a class of medications called anthelmintics. It works by killing the worms.
Praziquantel comes as a tablet to take by mouth with water and a meal. It is usually taken for one day as three doses; each dose spaced 4 to 6 hours apart. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take praziquantel exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Praziquantel tablets are marked with 3 notches so that they can easily be split. If your doctor has told you to take only part of a tablet, use your thumbnail to press down on the correct notch and separate the number of parts needed for your dose.
Swallow the tablets or tablet parts whole as soon as you put them into your mouth. Do not chew them, crush them, or hold them in your mouth. The bitter taste of the tablets may cause you to gag or vomit if you keep the tablets in your mouth before swallowing.
Praziquantel is also sometimes used to treat certain other worm infestations, including tapeworm (a type of worm that may attach to the wall of the intestine or may move to different parts of the body). Talk to your doctor about the risks of using praziquantel to treat your condition.
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
