Pfizer Helpful Answers

Important safety information

Zmax fights bacteria that cause infections. These include sinusitis and pneumonia. Like other antibiotics, Zmax takes time to work.

Do not take Zmax if you have a known allergy or hypersensitivity to azithromycin, erythromycin, or any antibiotic.

Call your doctor right away if you have hives, you have trouble swallowing, your face or throat swells, or you have wheezing or trouble breathing after taking Zmax.

Diarrhea is a common problem caused by antibiotics which usually ends when the antibiotic is discontinued. Sometimes, however, patients can develop watery and bloody stools (with or without stomach cramps and fever) even as late as two or more months after taking their last dose of the antibiotic. If this occurs, you should contact your doctor as soon as possible.

The most common side effects in adults taking Zmax are diarrhea/loose stools, nausea, and stomach pain. Others include headache and vomiting. For patients who took Zmax and got diarrhea, most symptoms went away by day 2. Call your doctor if you vomit within one hour of taking Zmax.
