What Is Praziquantel Used For?

Praziquantel is primarily used to treat:

Schistosomiasis (Bilharzia): Caused by blood flukes that live in blood vessels.

Clonorchiasis and Opisthorchiasis: Infections from liver flukes.

Paragonimiasis: Caused by lung flukes.

Cysticercosis and Neurocysticercosis: Infections from pork tapeworm larvae in body tissues or brain.

Taeniasis: Adult tapeworm infection in the intestine.

Diphyllobothriasis: Fish tapeworm infection.

Hymenolepiasis: Dwarf tapeworm infections.

The medication targets the worm’s outer protective covering, leading to paralysis and eventual death of the parasite. Buy Praziquantel Online at top pharmacy Medzsupplier.

Dosage and Administration

The dosage of Praziquantel varies depending on the type of infection, patient’s age, weight, and severity of infection. It is critical to follow a healthcare provider's instructions closely. Below are general guidelines:

1. General Dosing Information
Adults and children over 4 years old: The dose is calculated based on body weight, usually in mg/kg.

Typical doses:

Schistosomiasis: 20 mg/kg taken three times in a day (total 60 mg/kg/day).

Tapeworm infections: 5–10 mg/kg as a single dose.

Cysticercosis: 50 mg/kg/day in divided doses for 14 days.

Clonorchis or Opisthorchis infection: 25 mg/kg three times daily for 1–2 days.

Always consult your doctor or pharmacist before starting.

2. How to Take It
Form: Praziquantel comes in tablet form (usually 600 mg).

With food: Take the tablets with meals and a full glass of water.

Crushing tablets: Due to their large size and bitter taste, some patients may find it difficult to swallow them whole. Crushing and mixing them with semi-solid food may help, but this should only be done under professional advice.

Divided doses: If instructed to take multiple doses in a day, space them approximately 4–6 hours apart.

Precautions Before Use

Before taking Praziquantel, it is essential to inform your healthcare provider about:

Allergies: Any past allergic reactions to medications.

Pregnancy/Breastfeeding: Generally considered safe in pregnancy (especially after the first trimester), but consult your doctor.

Other medical conditions: Particularly liver disease, epilepsy, or a history of seizures.

Current medications: Praziquantel may interact with other drugs like rifampin, dexamethasone, or anti-epileptic drugs.

Possible Side Effects

Like all medications, Praziquantel may cause side effects, although not everyone gets them. Common side effects include:

Headache

Dizziness

Nausea or vomiting

Abdominal pain or discomfort

Fatigue

Fever (especially due to dying parasites triggering immune responses)

Rare but serious effects include allergic reactions, seizure-like symptoms, or severe skin rashes. Seek immediate medical attention if any severe reactions occur.

Drug Interactions

Some medications may affect how Praziquantel works or increase side effects:

Rifampin: Significantly reduces Praziquantel blood levels, decreasing effectiveness.

Anticonvulsants (e.g., phenytoin, carbamazepine): May lower blood concentration.

Cimetidine: May increase levels of Praziquantel in the body.

Grapefruit juice: Can affect metabolism of the drug — best to avoid.

Inform your doctor about all current medications and supplements you are taking.

Special Considerations

Neurocysticercosis patients: When treating tapeworm larvae in the brain, steroids and anti-seizure medications are often given simultaneously to manage inflammation.

Reinfection risk: In endemic areas, reinfection is common. Hygiene measures and follow-up tests may be recommended.

Monitoring: Stool and urine samples may be needed after treatment to ensure the parasites are fully cleared.

Missed Dose or Overdose
Missed Dose: Take as soon as you remember, but skip if it’s almost time for the next dose. Do not double up.

Overdose: May cause serious symptoms such as confusion, seizures, or difficulty breathing. Seek emergency medical help immediately.
