A Z-Pak, or azithromycin is a medication in a class of drugs known as macrolide antibiotics. Antibiotics work by killing harmful bacteria in the body. According to PubMed Health, azithromycin is used to treat infections caused by bacteria, such as bronchitis, pneumonia, sexually transmitted diseases, and infections of the ears, lungs, skin and throat. Patients who are prescribed a Z-Pak should complete the entire course of medication: Stopping treatment early can lead to a return or worsening of infection.
Stomach Discomfort
Stomach discomfort may occur in patients taking a Z-Pak. Symptoms may include stomach pain or upset, mild nausea, vomiting, diarrhea or constipation. Taking azithromycin with food or milk may help to lessen these effects. Patients can consider making small dietary changes if they experience stomach discomfort while taking azithromycin. Avoiding spicy, fatty or fried foods and eating small meals spaced throughout the day can help diminish stomach upset. Patients should drink an adequate amount of fluids throughout the day while taking this medication to avoid developing dehydration from vomiting and diarrhea. Severe stomach discomfort should be reported to a physician.
Mild Skin Rash
A mild skin rash can occur in patients taking a Z-Pak. This rash may or may not cause itching and discomfort. An over-the-counter cream that contains cortisone or a colloidal oatmeal bath may help to alleviate such symptoms. If a severe rash occurs accompanied by hives, difficulty breathing, and swelling of the tongue or throat it may be a sign of an allergic reaction to azithromycin and should be reported to a doctor immediately.
Headache and Dizziness
Patients taking a Z-Pak may experience headache and dizziness. These side effects may be temporary and lessen over time as the body gets used to azithromycin. Patients should use caution while driving or operating dangerous machinery until they know how this medication will affect them. A physician may be consulted regarding the use of acetaminophen or ibuprofen for the relief of headache pain and discomfort.
