Praziquantel
About Praziquantel
Praziquantel is a prescription medicine used to treat infections caused by parasitic worms, such as blood flukes and liver flukes. It works by targeting the parasites directly inside the body to clear the infection and prevent further complications. This medication is essential for stopping the spread of these parasites within your organs.
Unlike long-term therapies, this medicine is typically taken as a short-term treatment, often for just one day. You should take the tablets with water during a meal, and you must swallow them whole without chewing. To support your recovery and prevent getting infected again, it is important to practice strict personal hygiene and avoid consuming untreated water or undercooked freshwater fish.
While taking Praziquantel, you may experience mild side effects like a temporary headache, dizziness, or stomach discomfort. Most of these symptoms go away quickly on their own once the treatment is finished. However, if you experience more serious symptoms such as severe skin rashes, seizures, or an irregular heartbeat, you must contact your doctor immediately.
Before you begin taking this medicine, tell your doctor if you have a history of seizures, heart problems, or kidney disease. Do not take this if you have a parasitic infection in your eyes, known as ocular cysticercosis, as treating this area can cause severe damage to your vision. Your doctor will help determine if this treatment is safe for you.
This medicine can interact with other substances, including alcohol, which can make dizziness and drowsiness much worse. It may also interact with certain seizure medications and antibiotics, making the treatment less effective. If you are pregnant, breastfeeding, or managing health conditions as an older adult, talk to your doctor or pharmacist before starting treatment.

Patients Concern
Disease/Condition Glossary
Schistosomiasis: Schistosomiasis, also known as snail fever, Katayama fever, and bilharzia, is a disease caused by infection with freshwater parasitic flatworms called schistosomes. The parasites in the contaminated water penetrate human skin to enter into the bloodstream and migrate to various organs leading to infections. Symptoms include diarrhoea, bloody stools, blood in the urine, abdominal pain, joint pain, muscle pain, headache, cough, chills, fever, itchy skin, and rash.
Liver fluke infection: This infection is caused by parasitic worms called liver flukes after eating contaminated raw or uncooked watercress or freshwater fish. After ingestion, the liver flukes travel from the intestine to the bile ducts in the liver, where they live and grow. Symptoms include fever, nausea, vomiting, diarrhoea, abdominal pain, weakness, loss of appetite, and hives.
FAQs
Praziquantel is used to treat parasitic infections, including Schistosomiasis and liver fluke infection.
