Praziquantel is a common antiparasitic pill used to treat schistosomiasis and several tapeworm infections. It targets adult flatworms and helps your body clear them. If your doctor prescribes praziquantel, this quick guide will help you understand how to take it, what to watch for, and how to stay safe.
Dose depends on the infection. For many types of schistosomiasis the usual adult dose is about 40 mg per kg of body weight given as a single dose or split into two doses the same day. Simple tapeworm infections often use a single lower dose, commonly in the 5–10 mg/kg range, but some parasites need a longer or higher-dose course. Neurocysticercosis (brain tapeworm) requires specialist care and much longer treatment.
Take praziquantel with food. A meal, especially one with some fat, usually increases how well the drug is absorbed and can reduce stomach upset. Swallow tablets whole and follow the exact schedule your prescriber gives. If your course spans multiple days, don’t skip doses—if you miss one, take it when you remember unless it’s almost time for the next dose, then ask your prescriber what to do.
Common side effects include nausea, abdominal pain, headache, dizziness, and tiredness. These are usually mild and pass within a day or two. If you notice severe rash, swelling, trouble breathing, very fainting spells, or other signs of a strong allergic reaction, get emergency care.
People with liver problems, pregnant women, and breastfeeding mothers should check with their doctor before taking praziquantel. The drug can interact with some other medicines: certain anticonvulsants (like phenytoin or carbamazepine) and antibiotics such as rifampicin can lower praziquantel levels. Medicines like cimetidine can raise praziquantel levels. If you have epilepsy, treat parasite infections under close medical supervision because treatment can influence seizure control.
After treatment, your clinician may repeat stool or urine tests to confirm the infection is cleared. Keep follow-up appointments and tell your provider if symptoms continue—like persistent abdominal pain, blood in urine, or new neurological signs.
Thinking of buying praziquantel online? Only use licensed pharmacies that request a prescription, list real contact details, and have a licensed pharmacist available. Avoid sites offering prescription drugs without a prescription or with extremely low prices. When in doubt, ask your local pharmacist or healthcare provider to recommend a trusted source.
Practical checklist: take the full prescribed course, take tablets with food, avoid driving if you feel dizzy, report worrying side effects, and do follow-up testing. If you’re unsure about dose or interactions, call your prescriber—don’t guess.
