Praziquantel is an anthelmintic medicine - a drug that targets parasitic worms. It belongs to a class of chemicals that act specifically on flatworms, also known as flukes and tapeworms. In the UK, praziquantel is licensed by the Medicines and Healthcare products Regulatory Agency (MHRA) and is used to treat infections caused by these parasites. You will find this active ingredient in products such as Biltricide and generic praziquantel tablets.
A number of preparations on the UK market contain praziquantel. The most widely recognised brand is Biltricide, available as hard tablets of 600 mg strength. Generic versions of praziquantel are also sold, typically in 600 mg tablets, but some manufacturers offer lower-strength tablets (e.g., 300 mg) for paediatric use. All of these products are oral tablets; the tablets can be swallowed whole or, for children who have difficulty with large tablets, chewed and swallowed with water. Availability may vary between pharmacies, but each product includes the same active ingredient that delivers the therapeutic effect.
Praziquantel is prescribed for several worm infections that are common in tropical and subtropical regions, as well as occasional cases in the UK.
In each case, praziquantel works to eliminate the parasite, helping to resolve symptoms and prevent complications. The drug is approved for these uses by the MHRA, and in practice it is often the first-line option for these worm infections.
When taken, praziquantel is absorbed into the bloodstream and reaches the parasites that live inside the body. It disrupts the parasite’s outer membrane, causing a rapid influx of calcium ions. This makes the worm’s muscles contract and become unable to hold onto the host’s tissues. As a result, the parasites become paralyzed, detach, and are expelled or destroyed by the body’s immune system. The effect is usually seen within a few hours of taking the medication.
Most people experience only mild, short-lasting effects. Typical reports include:
These symptoms often lessen as the body adjusts, and they usually do not require medical attention.
Although rare, some reactions need immediate medical help. Watch for:
If any of these signs appear, seek urgent care.

Always read the patient information leaflet that comes with the specific product you have. For detailed usage, dosing, administration, refer to your specific medication's information.
