Nitazoxanide is an antiprotozoal medicine indicated in the United States for diarrhoea caused by Giardia lamblia or Cryptosporidium parvum in eligible patients. It is not a standard treatment for tapeworm infection.

How the medicine works

Its active metabolite interferes with essential energy metabolism in susceptible organisms.

Medical precautions and adverse effects

Abdominal pain, nausea, headache and urine discoloration may occur. Seek medical care for severe dehydration, blood in stool, persistent fever or diarrhoea. Effectiveness against Cryptosporidium in immunocompromised people is uncertain.

Diagnosis and treatment

A qualified clinician should confirm the infection and choose the appropriate treatment schedule. Avoid self-prescribing these medicines for unrelated or unproven uses. Some gastrointestinal infections also require fluids and prevention of reinfection.
