The price of praziquantel can vary depending on factors such as dosage, form (tablets or liquid), and the specific manufacturer or supplier. Generic versions are generally more affordable than branded products.
What is praziquantel used for?
Praziquantel is an antiparasitic medication primarily used to treat infections caused by flatworms, including schistosomiasis and tapeworm infestations [1]. It is listed on the World Health Organization's List of Essential Medicines [2].
How much does praziquantel cost?
Prices for praziquantel can range significantly. For example, a prescription for 600 mg praziquantel tablets might cost around $50 to $100 without insurance, but this can be reduced with discount cards or insurance. Over-the-counter praziquantel, if available, could be less expensive. The cost of praziquantel for large-scale public health programs, where it is often donated or purchased in bulk, is considerably lower [3].

Dosages are typically determined by the type of infection and the patient's weight. For schistosomiasis, a common adult dose is 40 mg/kg, taken as a single dose or divided over the day [1]. For tapeworm infections, the dosage might be lower, for instance, 10 mg/kg as a single dose [1]. It is crucial to follow a healthcare provider's instructions for correct dosage and administration.

Praziquantel works by increasing the permeability of the parasite's cell membrane to calcium ions. This leads to muscle contraction, paralysis, and eventual death of the parasite [1].
