Nizonide contains Nitazoxanide.

Product Overview

Nizonide is a medication containing the active ingredient Nitazoxanide. It is an antiprotozoal and antiviral agent used to treat various parasitic and viral infections. Nizonide works by interfering with the production of certain enzymes that are essential for the survival of parasites and viruses, thereby inhibiting their growth and replication. This medication is available in oral tablet form and is commonly prescribed to treat conditions such as giardiasis, cryptosporidiosis, and viral gastroenteritis.


Nizonide is primarily used to treat infections caused by protozoa and viruses. It is effective against parasites such as Giardia lamblia and Cryptosporidium parvum, which can cause gastrointestinal infections leading to diarrhea, abdominal cramps, and nausea. Nizonide is also used to treat viral gastroenteritis caused by rotavirus or norovirus, which commonly affect both adults and children, leading to symptoms such as diarrhea and vomiting.

How to Use

Nizonide tablets should be taken orally with a full glass of water, preferably with food to reduce the risk of gastrointestinal upset. The dosage and duration of treatment will depend on the specific condition being treated, as well as the individual’s age, weight, and medical history. It is important to complete the full course of treatment prescribed by a healthcare professional, even if symptoms improve before the medication is finished.

How it Works

Nizonide works by inhibiting the activity of certain enzymes that are essential for the survival and replication of parasites and viruses. Nitazoxanide, the active ingredient in Nizonide, interferes with the production of pyruvate ferredoxin oxidoreductase (PFOR) enzyme in parasites, which is crucial for their energy metabolism. By disrupting this process, Nizonide effectively kills the parasites and stops the progression of the infection.

Dosage and Administration

The recommended dosage of Nizonide for adults and children over 12 years of age is typically 500 mg orally twice daily for 3 days. For children aged 4 to 11 years, the dosage is usually 200 mg orally twice daily for 3 days. For children aged 1 to 3 years, the dosage is typically 100 mg orally twice daily for 3 days. Dosage adjustments may be necessary for patients with renal or hepatic impairment. It is important to follow the dosage instructions provided by a healthcare professional.


Nizonide offers several benefits for patients suffering from parasitic and viral infections. It effectively treats conditions such as giardiasis, cryptosporidiosis, and viral gastroenteritis, relieving symptoms such as diarrhea, abdominal cramps, and vomiting. Nizonide is generally well-tolerated and has a low risk of side effects compared to other antiparasitic and antiviral medications. Its convenient dosing regimen and short treatment duration make it a preferred choice for both adults and children.

Common Side Effects

Common side effects of Nizonide may include headache, nausea, abdominal pain, diarrhea, and dizziness. These side effects are usually mild and transient, resolving on their own without the need for medical intervention. However, if any side effects persist or worsen, it is important to consult a healthcare professional for further evaluation and management.


Nizonide should be used with caution in patients with known hypersensitivity to nitazoxanide or any other ingredients in the formulation. It is not recommended for use in pregnant or breastfeeding women unless the potential benefits outweigh the risks. Nizonide may interact with certain medications, so inform your doctor about all the medications you are currently taking, including prescription, over-the-counter, and herbal supplements.
