Praziquantel (PZQ), sold under the brandname Biltricide among others, is a medication used to treat a number of types of parasitic worm infections in mammals, birds, amphibians, reptiles, and fish.[3] In humans specifically, it is used to treat schistosomiasis, clonorchiasis, opisthorchiasis, tapeworm infections, cysticercosis, echinococcosis, paragonimiasis, fasciolopsiasis, and fasciolosis.[3] It should not be used for worm infections of the eye.[4] It is taken by mouth.[3]

Side effects in humans may include poor coordination, abdominal pain, vomiting, headache, and allergic reactions.[4] While it may be used during pregnancy, it is not recommended for use during breastfeeding.[4] Praziquantel is in the anthelmintic class of medications.[3] It works partly by affecting the function of the worm's sucker.[3]

Praziquantel was approved for medical use in the United States in 1982.[3] It is on the World Health Organization's List of Essential Medicines.[5]
