Praziquantel is an anthelmintic medication widely prescribed for treating parasitic worm infections in humans and animals. The drug is particularly effective against flatworms, including trematodes (flukes) and cestodes (tapeworms). Praziquantel is approved by health authorities worldwide and plays a vital role in combating a variety of parasitic diseases. Here, we’ll explore its uses, mechanisms, and importance in human and veterinary medicine.

Schistosomiasis
One of the most common uses of Praziquantel is to treat schistosomiasis, a disease caused by Schistosoma species of blood flukes. Schistosomiasis is prevalent in tropical and subtropical regions, particularly in areas with poor sanitation. The condition can lead to chronic illness, organ damage, and, in severe cases, death. Praziquantel works effectively by killing the adult worms, thereby stopping the disease's progression.
Tapeworm Infections
Praziquantel is highly effective against tapeworm infections caused by species such as Taenia solium (pork tapeworm) and Taenia saginata (beef tapeworm). It also treats infections caused by the fish tapeworm Diphyllobothrium latum. Tapeworm infections can result in malnutrition and abdominal discomfort. In more severe cases, larvae can migrate to organs, causing life-threatening complications like cysticercosis.
Neurocysticercosis
Neurocysticercosis occurs when tapeworm larvae infect the central nervous system, leading to seizures, headaches, and neurological symptoms. Praziquantel is one of the first-line treatments for this condition, used alongside corticosteroids to manage inflammation caused by the dying parasites.
Clonorchiasis and Opisthorchiasis
These liver fluke infections, caused by Clonorchis sinensis and Opisthorchis viverrini, are common in parts of Asia. Chronic infection can lead to liver damage, bile duct obstruction, and an increased risk of bile duct cancer. Praziquantel effectively clears these infections.
Echinococcosis
Although Albendazole is the primary treatment for hydatid disease (caused by Echinococcus species), Praziquantel may be used in combination therapy to target specific stages of the parasite.
Praziquantel disrupts the parasite’s cell membrane by increasing its permeability to calcium ions. This causes muscle contraction and paralysis in the worm, leading to its dislodgement from the host’s tissues. Once detached, the parasite is destroyed by the body’s immune system or expelled via the gastrointestinal tract.
In veterinary medicine, Praziquantel is commonly used to deworm pets, such as dogs and cats. It is highly effective against tapeworm species, including Dipylidium caninum, which is transmitted by fleas. Combined formulations with other deworming agents, like pyrantel or febantel, provide broad-spectrum protection against multiple parasitic worms in animals.
Praziquantel is also employed in livestock management to control fluke and tapeworm infestations, ensuring healthier herds and preventing economic losses.
Praziquantel tablets are available in various strengths, typically taken orally with water. The dosage depends on the infection type, severity, and the patient’s body weight. It is crucial to follow medical advice regarding dosage to ensure effective treatment and avoid resistance.
Praziquantel is generally well-tolerated, but some people may experience mild side effects like nausea, abdominal discomfort, headache, or dizziness. In rare cases, allergic reactions or severe side effects like seizures may occur, particularly in individuals with neurocysticercosis. It is not recommended for pregnant women in their first trimester unless necessary.
For pets, Praziquantel is safe when administered according to veterinary guidelines. Overdosing can lead to vomiting, lethargy, or loss of appetite.
Praziquantel is listed as an essential medicine by the World Health Organization (WHO) due to its significant role in treating neglected tropical diseases (NTDs). Mass drug administration programs rely on Praziquantel to reduce the burden of schistosomiasis and other parasitic diseases in endemic areas.
