Nitazoxanide is an antiparasitic and antiviral medicine. It has been used to treat certain parasitic infections, and it has also been studied for viral infections.
What parasitic infections does nitazoxanide treat?
Nitazoxanide is used for gastrointestinal parasitic infections, particularly those that cause diarrhea, including infections caused by protozoa such as Giardia and Entamoeba histolytica (amoebiasis).
How is nitazoxanide used for diarrhea?
In practice, nitazoxanide is prescribed when diarrhea is linked to specific protozoal causes (commonly Giardia or amoebic infections). Clinicians base the choice on symptoms plus diagnostic testing when available.
Is nitazoxanide used for viral infections (like COVID-19 or flu)?
Nitazoxanide has been studied for antiviral activity against viruses, including respiratory viruses. However, whether it is recommended or used routinely depends on the specific virus, evidence quality, and local medical guidance.
What dose and course length are typically used?
The exact dose and treatment duration depend on the condition being treated, the patient’s age, and local prescribing guidance.
Who should avoid or be cautious with nitazoxanide?
People should follow their clinician’s instructions, especially if they are pregnant, breastfeeding, have liver disease, or take other medications that could interact.
What are common side effects people report?
Common side effects can include stomach or digestive symptoms such as nausea, vomiting, diarrhea, or abdominal discomfort, depending on the person and dose.
When should someone seek medical care instead of self-treating?
If diarrhea is severe, lasts more than a few days, includes blood, or comes with dehydration (dizziness, very low urine output, inability to keep fluids down), medical evaluation is needed.

I can add precise “uses” (with exact approved indications) if you tell me your country/region and whether you mean prescription or over-the-counter nitazoxanide.
