Azithromycin
Summary
Azithromycin is used to treat various bacterial infections. These include respiratory infections like pneumonia, bronchitis, sinusitis, ear infections, skin infections, sexually transmitted infections such as chlamydia and gonorrhea, and traveler's diarrhea caused by certain bacteria. It may also be used for chronic obstructive pulmonary disease (COPD) exacerbations and H. pylori eradication in combination with other drugs.
Azithromycin works by inhibiting bacterial protein synthesis. This prevents the bacteria from growing and multiplying, effectively stopping the infection. It is effective against a wide range of bacteria.
The usual dosage for adults is 500 mg daily for 3-5 days for most infections. For chlamydia, a single dose of 1 gram is prescribed. It can be taken with or without food and should not be taken with antacids containing aluminum or magnesium.
Common side effects include nausea, vomiting, diarrhea, abdominal pain, and headache. Serious but rare adverse effects may include heart rhythm changes, liver toxicity, allergic reactions, and Clostridium difficile-associated diarrhea.
Azithromycin can cause heart conditions like QT prolongation and arrhythmias, so use with caution if you have heart problems. It should also be used cautiously in patients with liver impairment. Serious allergic reactions, including anaphylaxis, may occur. It can interact with drugs affecting heart rhythm or liver function. Discuss use during pregnancy with a doctor.
