What is nitazoxanide used for?
Nitazoxanide is an antiprotozoal used for diarrhoea caused by Giardia or Cryptosporidium. It is not a general treatment for every cause of diarrhoea.
Does it come in more than one form?
It is supplied as tablets and an oral suspension. Follow the instructions for the exact product supplied and ask a pharmacist to explain unfamiliar directions.
What should I discuss before taking it?
Mention allergies, liver or kidney disease, HIV or other immune-system problems, pregnancy and breastfeeding. Bring a list of medicines and supplements so interactions can be checked.
Can I stop the course when I feel better?
Finish the prescribed course unless your clinician advises otherwise. Stopping early or skipping doses may leave the infection incompletely treated.
What side effects can occur?
Stomach pain, headache, nausea and discoloured urine are reported. Contact a clinician about severe, persistent or unusual symptoms.
What if diarrhoea continues after treatment?
Contact your doctor if diarrhoea persists after the course. Drink fluids to help prevent dehydration, and seek advice if you cannot maintain your fluid intake.
