Indications 

Alinia is a prescription medicine for treating diarrhea caused by protozoa, such as giardia lamblia or cryptosporidium parvum. 

As an antiprotozoal agent, Alinia halts the growth of diarrhea-causing protozoa by disrupting the pyruvate: ferredoxin oxidoreductase (PFOR) enzyme-mediated electron transfer reaction, necessary for anaerobic energy metabolism. 

Uses and Dosage 

Before taking Alinia and with each prescription refill, carefully read its medication guide and patient information leaflet. Do not hesitate to ask your doctor or pharmacist for any questions or concerns. 

Typically, Alinia is prescribed to be taken with food every 12 hours for a 3-day duration, as directed by a healthcare provider. 

For optimal efficacy, maintain a consistent level of this medication in your system by taking it regularly at evenly spaced intervals. 

To avoid the recurrence of the infection, take the full course of Alinia as prescribed, even if symptoms subside after a few doses. 

Side Effects 

Alinia does not usually have severe side effects; however, common side effects may still occur, such as:  

• Nausea 
• Stomach pain 
• Headache 
• Discolored urine 

If any of these side effects last or worsen, inform your doctor promptly. 

Allergic Reactions 

Alinia rarely causes severe allergic reactions. However, get emergency medical help if you experience the following signs of an allergic reaction: 

• Rash 
• Itching or swelling, especially of the throat, tongue, and face 
• Severe dizziness 
• Trouble breathing 

This list does not contain all the potential side effects of Alinia. Inform your doctor promptly if any unlisted effects occur. 

Cautions 

Before starting treatment with Alinia, inform your doctor or pharmacist if you have any known allergies, especially to nitazoxanide, any medications, or any ingredients present in Alinia tablets. 

To ensure Alinia is safe for you, disclose to your physician your medical background, specifically regarding any history of: 

• An immune system that has been compromised (e.g., due to HIV infection) 
• Liver disease 
• Kidney disease 

Many medicines may interact with Alinia. To lower the risk of drug interactions, disclose to your doctor and pharmacist all the medications you currently use, including prescription and non-prescription drugs, dietary supplements, and herbal products. 

Alinia should only be used during pregnancy if absolutely necessary. Consult with your doctor to weigh the potential risks and benefits. 

Before taking Alinia, inform your doctor if you are nursing a baby, as it is uncertain whether nitazoxanide is excreted in breast milk and could be harmful to the baby.
