Nitazoxanide Diarrhea Prescription Usage And Dosage | Forum

The nitazoxanide 500mg is an antiparasitic and antiviral medication commonly prescribed to treat diarrhea caused by protozoal infections, such as Cryptosporidium parvum or Giardia lamblia. The typical dosage for adults is 500 mg taken orally every 12 hours for 3 days, usually with food to minimize stomach upset. For pediatric patients aged 1-11, the dosage is adjusted based on weight. It's important to complete the full course even if symptoms improve. Side effects may include abdominal pain, nausea, or headache. Always follow your healthcare provider's instructions for correct dosage and usage, and avoid self-prescription.
