Nitazoxanide 500 mg Tablet
Nitazoxanide is a potent antiprotozoal and antiviral drug used primarily to treat diarrhea caused by parasitic infections. The most common organisms include Giardia lamblia and Cryptosporidium parvum. It works by inhibiting parasite energy metabolism, allowing the body to eliminate the infection through the gastrointestinal tract.

Giardiasis: Treats intestinal infection causing bloating, cramping, and watery stools.
Cryptosporidiosis: Useful for infections linked to contaminated water.
Broad Spectrum Activity: May offer benefits against various parasites and some viral infections.
Administration
Take with Food: Very important—food increases drug absorption (bioavailability) significantly.
Usual Adult Dose: 500 mg twice daily (every 12 hours) for 3 days.
Complete the Course: Even if symptoms improve early, do not miss doses and finish the full course.
Swallow Whole: Take the tablet whole with a full glass of water—do not crush or chew.
