Schistosomiasis (bilharzia) - Treatment 

Treating schistosomiasis 

If you are diagnosed with schistosomiasis, you will probably be admitted to hospital so that your health can be carefully monitored. This will help ensure that any serious complications you have, such as dehydration, are picked up.

The medication used to treat schistosomiasis is called praziquantel. Praziquantel works by first paralysing the worms and then dissolving their outer casing, killing them. A single dose of praziquantel is usually required.

The side effects of praziquantel are usually mild and include:

  • nausea
  • vomiting
  • abdominal pain

Steroid medication (corticosteroids) can also be used to relieve the symptoms of acute schistosomiasis as they help control the allergic reaction to the eggs that is responsible for the symptoms.

A further stool sample may be taken after four to six weeks to check whether there are still any eggs in your stools. If eggs are present, a further dose of praziquantel may be given.
