Tetrazin 500 mg Tablet

Tetrazin 500 mg Tablet is a prescription-strength tablet that contains 500 mg of nitazoxanide in each tablet. Nitazoxanide is an anthelmintic/anti-worm medicine used to treat certain parasitic infections, including intestinal infections caused by protozoa and some worm-related illnesses depending on your doctor’s diagnosis. This strip/box of 10 tablets is designed for short-course treatment under medical guidance. Tetrazin 500 mg Tablet is taken by mouth and is often chosen when an adult or older teen needs a full-strength tablet dose rather than a lower-strength product.

How it works: Nitazoxanide works by interfering with how certain parasites make energy, which helps stop them from surviving and multiplying in the gut. As a tablet, Tetrazin 500 mg Tablet delivers the medicine in a convenient solid dose that your body can absorb after you swallow it.

Tetrazin 500 mg Tablet is a higher-strength nitazoxanide tablet, so it is best suited for patients whose doctor has determined that this exact 500 mg dose is appropriate. Because each tablet already provides the full 500 mg amount, it can simplify dosing compared with lower-strength forms that require taking more than one tablet per dose. This strength is typically selected for standard treatment schedules in adults and older adolescents.

• Treatment of certain intestinal parasitic infections
• Giardiasis
• Cryptosporidiosis
• Other nitazoxanide-sensitive protozoal infections as prescribed

• Swallow Tetrazin 500 mg Tablet whole with water unless your doctor gives different instructions.
• Take it with food, because nitazoxanide is usually better tolerated and absorbed with a meal.
• Take it at the same times each day if your prescription is for more than one dose.
• Do not crush or chew the tablet unless a pharmacist or doctor specifically says it is okay.
• Finish the full course even if you start to feel better.
• If you miss a dose, take it when you remember unless it is almost time for the next dose; do not double up.

Each Tetrazin 500 mg Tablet contains 500 mg of nitazoxanide, which is the standard tablet dose for this strength. How often you take it depends on your diagnosis, age, and kidney/liver health, but nitazoxanide is commonly prescribed twice daily with food for a short course. Do not exceed the amount your doctor prescribes; your clinician sets the exact schedule and maximum daily dose for your situation.

Do not change your dose or stop the medicine without speaking to your doctor.
