What is nitazoxanide 500mg used for?

Quote

Nitazoxanide 500mg is a prescription medication used to treat diarrhea caused by certain parasites in the intestines. These parasites are:

  • Cryptosporidium parvum: This parasite can cause watery diarrhea, abdominal cramps, and dehydration.
  • Giardia lamblia (Giardia): This parasite can cause similar symptoms to Cryptosporidium, along with nausea, weight loss, and gas.

How it Works:

Nitazoxanide works by interfering with the parasite's ability to function and reproduce. This eventually leads to the death of the parasite and resolves the diarrhea.

Important to Remember:

  • Nitazoxanide is only available by prescription. Your doctor will diagnose the cause of your diarrhea before prescribing it.
  • It's typically taken as a single dose.
  • While effective against these specific parasites, nitazoxanide won't work for other causes of diarrhea, such as bacterial or viral infections.
