Azithromycin is FDA-approved to treat bacterial infections caused by susceptible strains of microorganisms that cause different bacterial infections. Infections include acute bacterial sinusitis, acute bacterial exacerbations of chronic bronchitis, community-acquired pneumonia, pharyngitis, tonsillitis, uncomplicated skin and skin structure infections, urethritis, cervicitis, and genital ulcer disease in men.
Azithromycin is part of a medication class known as macrolide antibiotics, which work by stopping bacterial growth.
Also known as a Z-Pak, Zithromax (azithromycin) is the brand-name version and was approved by the FDA in 2002. Generic azithromycin was FDA-approved in 2005.
Off-label uses of azithromycin include the treatment of salmonella and long-term prophylaxis, or preventative care, for bronchiolitis obliterans (BO) in people who’ve had lung transplants. BO is a rare chronic lung disease that gets worse over time.
Azithromycin is in the drug class of macrolide antibiotics. Macrolide antibiotics work by killing or preventing the growth of bacteria.
Azithromycin binds to the bacterial ribosome and prevents protein synthesis, which stops the bacteria from spreading. A ribosome is a tiny machine in your cells that creates proteins from amino acids during a process known as protein synthesis. Protein synthesis is typically good for your body, but you don’t want bacteria to go through protein synthesis when you have a bacterial infection. That’s how bacteria grows and keeps you sick.
Azithromycin won’t work for viral infections, like the flu, colds, or others. Viruses and viral infections require different treatments.
Azithromycin is FDA-approved to treat several types of mild to moderate bacterial infections. These infections include tonsilitis, pneumonia, skin infections, acute bacterial sinusitis, genital ulcer disease, acute bacterial exacerbations of chronic obstructive pulmonary disease (COPD), inflammation of the urethra (urethritis), and inflammation of the cervix (cervicitis).
Your healthcare provider can also prescribe azithromycin for off-label uses, including the treatment of salmonella and long-term prophylaxis for BO in people who’ve had lung transplants. The FDA has issued a warning about how the long-term use of azithromycin after a donor stem cell transplant can boost your risk of cancer relapse.
Azithromycin can treat bacterial infections in adults and children over the age of 6 months. It’s not recommended for children under the age of 2 for strep throat or tonsil infections.
Azithromycin shouldn’t be used in people with pneumonia who can’t take oral therapy due to moderate to severe illness, medical conditions, or risk factors, including any of the following:
• Cystic fibrosis
• Nosocomial infections
• Known or suspected bacteremia (bacteria in the blood)
• Requiring hospitalization
• Elderly or debilitated
• Significant underlying health issues that can compromise their ability to respond to their illness, including immunodeficiency

Azithromycin and Zithromax oral tablets come in 250-milligram and 500-milligram strengths. There are also 250-milligram oral capsules and 200-milligram liquid azithromycin in 5 milliliters available. Azithromycin also comes in single-dose vials for injection at 500 milligrams per vial.
The typical dosage for azithromycin is 500 milligrams per day for 3 to 10 days. Your healthcare provider can prescribe you a one-off higher dose of 1 or 2 grams for some bacterial infections.
The dosage for azithromycin is lower for children and people with kidney or liver issues.
You typically need to take a single dose of azithromycin per day. Make sure to take azithromycin at the same time every day. Swallow the oral capsules and tablets whole with a drink of water. Take capsules at least 1 hour before or 2 hours after eating. You can take tablets or liquid azithromycin with or without food.
If you miss a dose of azithromycin, take it as soon as you remember. If it’s almost time for your next dose, simply skip the missed dose and take the next dose at the normal time.
Store azithromycin tablets at room temperature and away from extreme heat and moisture. You can store liquid azithromycin either in the refrigerator or at room temperature, but don’t keep the liquid for more than 10 days.

Azithromycin and amoxicillin are 2 of the most commonly used antibiotics. Amoxicillin is FDA-approved to treat bacterial infections found in the ears, nose, throat, and other areas. Like azithromycin, amoxicillin works by killing or preventing the growth of bacteria.
While azithromycin is approved to treat adults and children 6 months and older, amoxicillin can be used in pediatric patients as young as 3 months old. Also, amoxicillin is in the penicillin family, so people who are allergic to penicillin should avoid taking it and take a macrolide like azithromycin instead.
The most common side effects of amoxicillin include nausea, vomiting, diarrhea, dizziness, anxiety, insomnia, and mild abdominal pain.
The best way to find out which antibiotic is best for you, if any, is to talk to a licensed healthcare provider.
