What are the side effects of nitazoxanide tablets?

What are …

Nitazoxanide 200mg , sold under the brand name Alinia, is a prescription medication used to treat diarrhea caused by specific parasites – Giardia lamblia (giardiasis) and Cryptosporidium parvum (cryptosporidiosis). While it effectively combats these intestinal foes, it's essential to be aware of its potential side effects. 

Common Side Effects

Taking nitazoxanide tablets may lead to some side effects, but they are often mild and temporary. Here's a breakdown of the most frequently reported ones:

  • Nausea: This is the most common side effect, occurring in up to 30% of people taking nitazoxanide. It usually appears soon after starting the medication and may improve over the course of treatment.
  • Stomach pain or cramping: Abdominal discomfort can also be a bothersome side effect, affecting around 10% of users. 
  • Headache: Headaches are another potential side effect, although less frequent than nausea and stomach pain.

Less Common Side Effects

While less prevalent, some additional side effects can occur with nitazoxanide:

  • Discolored urine: Your urine might appear orange or yellow-brown during treatment. This is usually harmless and resolves once you stop taking the medication.
  • Dizziness: Feeling lightheaded or dizzy can occur in some individuals.
  • Loss of appetite: You might experience a temporary loss of appetite while taking nitazoxanide.

Important Considerations

  • Severity and Duration: The severity and duration of these side effects can vary from person to person. For some, they might be mild and short-lived, while others might experience them more intensely.

  • Management Tips: There are ways to manage these side effects. Taking nitazoxanide with food can help minimize stomach upset. If headaches persist, over-the-counter pain relievers like acetaminophen (Tylenol) might be helpful, but consult your doctor first.
  • Allergic Reactions: Severe allergic reactions to nitazoxanide are rare, but it's crucial to seek immediate medical attention if you experience symptoms like hives, difficulty breathing, or swelling of the face, lips, or tongue.

Benefits of Nitazoxanide

Despite the potential side effects, nitazoxanide offers significant benefits for treating parasitic diarrhea:

  • Effective Treatment: It effectively eliminates Giardia lamblia and Cryptosporidium parvum, the parasites responsible for diarrhea.
  • Single-Dose Regimen: For giardiasis, a single dose of nitazoxanide is often sufficient. For cryptosporidiosis, a three-day course of medication is typically prescribed. This short treatment duration can be advantageous compared to some other antiparasitic medications.
  • Improved Quality of Life: By effectively treating parasitic diarrhea, nitazoxanide can significantly improve your quality of life by alleviating symptoms like loose stools, cramps, and dehydration.

Additional Considerations

  • Not a First-Line Treatment: Nitazoxanide is usually prescribed when other medications haven't been effective or are not suitable for the patient.

  • Not for All Parasites: It's important to note that nitazoxanide is not effective against all types of parasites. Your doctor will diagnose the specific parasite causing your diarrhea to determine if nitazoxanide is the right treatment.
  • Pregnancy and Breastfeeding: Nitazoxanide should not be taken during pregnancy or while breastfeeding unless specifically advised by your doctor due to potential risks to the developing baby.
  • Limited Information: Since Super Vidalista might not be approved in all regions and isn't a well-established brand, reliable information about its effectiveness and safety can be scarce.
  • Potential for Drug Interactions: Combining tadalafil and sildenafil increases the risk of interactions with other medications you might be taking. A doctor can assess these risks and ensure Super Vidalista wouldn't interfere with your current prescriptions.
  • Dosage Concerns: The appropriate dosage for Super Vidalista is unclear without a doctor's guidance. Taking too much of either tadalafil or sildenafil can lead to serious side effects.

Alternatives to Consider

  • There are many safe and effective ED medications available, including generic versions of Viagra and Cialis.

  • A doctor can discuss these options with you and find the best fit for your individual needs and medical history.


  • Super Vidalista should only be taken under the supervision of a doctor who is aware of your complete medical picture.
  • There are safer and more regulated alternatives available for treating ED.
