What is Azithromycin?

Azithromycin is a medication used to treat infections caused by bacteria. It belongs to a class of medications called macrolide antibiotics. It works by inhibiting the growth of bacteria [1].

It is a prescription only medication and should be taken only under the supervision of a doctor.

How Azithromycin Works

The working mechanism of Azithromycin involves stopping bacteria from making the proteins they need to grow and multiply. By doing this it prevents the spread of bacteria, allowing the body’s immune system to eliminate the infection effectively [2].

What is Azithromycin Used for?

Azithromycin is used to treat a broad range of bacterial infections, including:

  • Chest infections like pneumonia
  • Throat, ear and nose infections such as sinus infections
  • Skin infections
  • Lyme disease
  • Some sexually transmitted infections (STIs)

Why is the course only 3 or 5 days?

Azithromycin is usually prescribed for 3 to 5 days because it has a long elimination half-life of approximately 68 hours and remains in body tissues for several days after the last dose. It accumulates in infected tissues and continues to exert its antibacterial effect even after treatment has ended. Therefore, a short course can be effective against susceptible bacteria for certain infections.

Azithromycin strengths and forms

Azithromycin is available in different strengths and forms, depending on the product and treatment required. Common tablet strengths include 250 mg and 500 mg, while oral suspensions are also available.

Our product range includes Azithromax 250 mg tablets. The appropriate strength, dosage and duration of treatment are determined by your prescriber based on the infection, your age, medical history and other factors.

How to take azithromycin

  • Take it as your doctor tells you.
  • It is usually taken once a day; take it at the same time each day.
  • You can take it with or without food.
  • Finish all the medicine for the number of days your doctor prescribed.
  • Swallow the whole tablet with a glass of water.
  • Do not crush or break the tablet.
  • Do not stop taking this antibiotic abruptly.

Missed dose

If you miss a dose of azithromycin, take it as soon as you remember, unless it's nearly time for your next dose. In this case, skip the missed dose and take your next dose at the usual time.

Never take two doses at the same time or an extra dose to make up for a missed one.

Overdose

Do not take more than the prescribed dose of Azithromycin as it can lead to an overdose. Symptoms of Azithromycin overdose can include:

  • Nausea
  • Diarrhea
  • Vomiting

In the event of an overdose, consult your healthcare provider.

Seek medical help if you think you have taken too much.

Alcohol

Azithromycin vs amoxicillin and doxycycline

Azithromycin, amoxicillin and doxycycline belong to different groups of antibiotics and are used to treat different bacterial infections. Azithromycin is a macrolide antibiotic, amoxicillin is a penicillin, and doxycycline is a tetracycline. Azithromycin may be prescribed as an alternative for people who are allergic to penicillin depending on the infection. It is often prescribed as a short course of 3 to 5 days, although the duration may vary. Amoxicillin and doxycycline have different uses, precautions and dosing schedules.

The best choice among the three depends on the type of infection, medical history and bacterial susceptibility. Therefore always consult your healthcare provider to decide which antibiotic is best for your condition.
