How Long Does Nitazoxanide Take to Work?

Nitazoxanide 200 mg typically starts working within 24 to 48 hours after the first dose. It is commonly prescribed for parasitic infections like giardiasis and cryptosporidiosis, and often leads to symptom relief—such as reduced diarrhea and abdominal discomfort—within 2 to 3 days of starting treatment. However, the full course, usually lasting 3 days, should be completed even if symptoms improve early. In some viral infections or off-label uses, response times may vary. https://www.dosepharmacy.com/nizonide-200mg-tablet
