Azithromycin is available in the following forms:

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

The typical starting dose of azithromycin varies depending on the infection being treated, the severity of symptoms, and individual patient factors. It is crucial to follow your healthcare provider's instructions regarding dosage and administration.

For most infections:

• Adults: Typically, 500 mg on the first day followed by 250 mg once daily for the next 4 days.
  
• Children: Dosage is based on body weight and must be determined by your doctor.
  
  

For sexually transmitted infections like chlamydia:

• Adults: A single dose of 1 gram (1000 mg).
  
  

The dosage may be adjusted based on the response and tolerance to the medication. Your healthcare provider will determine the most appropriate dose based on your medical history and your response to the medication.

Azithromycin should be taken exactly as prescribed by your healthcare provider. Do not exceed the recommended dose or duration of treatment without consulting your provider.

If you have any questions about your dosage or need adjustments, contact your healthcare provider for guidance. If you want to talk to a provider right away, consider scheduling an online doctor appointment through a telehealth platform like Sesame.

If you miss a dose of azithromycin, take it as soon as you remember unless it is close to the time for your next scheduled dose. In that case, skip the missed dose and continue with your regular dosing schedule. Do not double the dose to make up for a missed one.

Take azithromycin around the same time every day to ensure effectiveness.

Continue taking azithromycin as prescribed by your healthcare provider, even if you start feeling better. Completing the full course of the medication is crucial to ensure that the infection is fully treated and to prevent the development of antibiotic resistance.

If you have any concerns or questions about your medication, discuss them with your healthcare provider for medical advice and recommendations.

Store azithromycin according to the instructions provided by your healthcare provider or pharmacist. Keep it at room temperature, away from light and moisture. Ensure the container is tightly closed and out of reach of children.

Do not use expired medication or medications that appear damaged or discolored. If you have any questions about storage, consult your healthcare provider or pharmacist for guidance.
