What is Azithromycin (Zithromax)?

Azithromycin (brand name: Zithromax) is a macrolide antibiotic used to treat a wide range of bacterial infections, including respiratory infections, ear infections, skin infections, and sexually transmitted diseases. It works by inhibiting the growth of bacteria, helping to eliminate the infection from the body.

Azithromycin is available in tablet, liquid suspension, and injectable forms.

Before Using This Product

• Discuss your medical history with your healthcare provider, particularly if you have liver disease, kidney disease, myasthenia gravis, or heart rhythm disorders.

How Should I Take Azithromycin (Zithromax)?

• Dosage: Typical dosages for adults range from 250 mg to 500 mg daily, depending on the infection being treated. A common regimen includes a single high dose on the first day, followed by lower doses for the next 4 days (Z-Pak).
• With or Without Food: Azithromycin can be taken with or without food, but taking it with food may reduce stomach upset.

• If it is almost time for the next dose, skip the missed dose and continue with your regular schedule.
• Do not double doses to make up for a missed dose.
