Azithromycin is a medication used to treat various bacterial infections, such as respiratory infections, skin infections, ear infections, and sexually transmitted infections (like chlamydia and gonorrhea). It belongs to a class of medications known as antibiotics.

Azithromycin is used to treat a variety of bacterial infections. This includes:

• Respiratory infections: Such as pneumonia and bronchitis
  
• Skin infections: Such as impetigo and cellulitis
  
• Ear infections
  
• Sexually transmitted infections: Such as chlamydia and gonorrhea
  
  

Azithromycin belongs to a class of medications known as macrolide antibiotics. These medications work by stopping the growth of bacteria. They achieve this by interfering with the ability of bacteria to make proteins that are essential for their growth and survival. Without these proteins, the bacteria cannot grow and replicate, which helps to control the infection.

Azithromycin is available in the following forms:

• Oral tablets
  
• Oral suspension (liquid)
  
• Oral packet
  
• Injectable form
  
  

The dosage and length of treatment depend on the condition being treated, its severity, and how you tolerate the medication.

Follow your healthcare provider's instructions regarding dosage and schedule. Do not exceed the prescribed dose or duration of treatment without consulting your provider.

The effectiveness of azithromycin and the time it takes to notice improvement can vary among individuals. For most infections, symptoms begin to improve within a few days of starting the medication.

Continue taking azithromycin as prescribed even if you start feeling better. Completing the full course of the medication is crucial to prevent the return of antibiotic-resistant bacteria.

While azithromycin is primarily used to treat various bacterial infections, healthcare providers may sometimes prescribe it off-label for other conditions.

Discuss any alternative uses of azithromycin with your healthcare provider.

• Oral tablets: Typically available in 250 mg and 500 mg
