This medication is used to treat infections of certain parasites (e.g., Schistosoma and liver flukes). Curing parasitic infections helps to improve your health and quality of life. Praziquantel belongs to a class of drugs known as anthelmintics. It works by killing the parasites. It also paralyzes the parasites, causing them to release their hold on the blood vessel walls so the body can remove them naturally.
How to use Praziquantel Tablet

Do not chew or suck the tablets because the bitter taste of praziquantel may cause gagging or vomiting. Your doctor may direct you to take this medication fewer than 3 times a day or to take it for longer than 1 day. Follow your doctor's directions exactly.
If you have trouble swallowing the tablets or tablet segments, you may crush the medication and mix it in soft foods or liquids. Take the mixture within 1 hour of mixing.
