Praziquantel is an antiparasitic medication widely used to treat various parasitic worm infections in both humans and animals. Belonging to the anthelmintic class of drugs, it is primarily effective against flatworms, including tapeworms (cestodes) and flukes (trematodes). Available in tablet form, Praziquantel offers a convenient and reliable treatment for infections caused by parasites like Schistosoma, Taenia, Clonorchis, and Opisthorchis species.

How Does Praziquantel Works?
Praziquantel works by interfering with the parasite’s cell membrane permeability. It increases calcium ion influx into the parasite’s muscle cells, causing sustained muscle contraction and paralysis. This action leads to the dislodgement of the parasite from the host's tissues, making it easier for the body to eliminate them. The drug also damages the parasite’s outer surface, exposing it to immune attack and digestive enzymes, thereby ensuring complete eradication.

Parasites Treated with Praziquantel
Schistosomiasis: One of the most common uses of Praziquantel is for treating schistosomiasis, caused by Schistosoma species. It is endemic in many parts of Africa, Asia, and South America and affects millions worldwide. A single dose or short course of Praziquantel is highly effective in reducing worm burden and disease progression.
Liver Fluke Infections: Praziquantel is effective against liver flukes such as Clonorchis sinensis and Opisthorchis viverrini, which can cause chronic inflammation, bile duct obstruction, and even cholangiocarcinoma if left untreated.
Tapeworm Infections: The drug is also indicated for treating various tapeworm infections, including those caused by Taenia saginata (beef tapeworm), Taenia solium (pork tapeworm), and Diphyllobothrium latum (fish tapeworm). It can also be used for neurocysticercosis, a potentially life-threatening condition caused by T. solium larvae entering the central nervous system.
Intestinal Flukes: Infections from intestinal flukes such as Fasciolopsis buski are also treated effectively with Praziquantel, especially in endemic rural areas with poor sanitation.
Dosage and Administration
Praziquantel tablets are usually taken orally with water and should be swallowed whole, not chewed or crushed, due to their bitter taste. The dosage depends on the type of infection, patient’s weight, age, and severity of the condition. In most cases, a single-day treatment is sufficient, although some conditions may require repeated doses over several days. It is essential to follow the doctor’s prescription to ensure the highest efficacy and minimize the risk of reinfection or resistance.
Safety and Side Effects
Praziquantel is generally well-tolerated, but some individuals may experience mild side effects such as headache, dizziness, nausea, abdominal pain, or fatigue. These symptoms are usually short-lived and subside without intervention. Rarely, allergic reactions or more severe side effects may occur. People with known hypersensitivity to the drug or those with liver impairment should consult a physician before starting treatment.
Special Considerations
Praziquantel is considered safe for use in children over 4 years of age and in pregnant women during the second and third trimesters. However, it should be used with caution under medical supervision. In patients with central nervous system involvement like neurocysticercosis, co-treatment with corticosteroids may be necessary to control inflammation caused by dying parasites.
Conclusion
Praziquantel tablet is a highly effective and versatile antiparasitic medication used to treat a broad range of parasitic worm infections. Its safety profile, ease of administration, and potent efficacy make it a frontline treatment in both individual and mass deworming programs globally. Timely administration of Praziquantel not only treats the infection but also helps in preventing long-term complications and controlling the spread of parasites in the community.
