About Azithromycin

Azithromycin is one of the most common medications prescribed to treat the sexually transmitted infection (STI) chlamydia trachomatis bacteria, also known as chlamydia.  In trials, this particular medication was found to be safe and effective in nearly 98% of patients, making it a popular choice with doctors when looking to treat the infection and it is available with a prescription from Click Pharmacy.

Chlamydia is very easy to transmit through any form of unprotected sexual contact with a carrier; as such it is the most common sexually transmitted infection in the UK, with Public Health England declaring it as accounting for almost half of all STI diagnoses each year. Depending on where the infection initially enters the body, the bacteria will invade the mucosal tissues of areas including the vagina, cervix, urethra and rectum, as well as the throat in the case of oral sex.

The information provided in the summary table is for reference only. It is important to consult a qualified healthcare professional before starting any chlamydia treatment, including Azithromycin

How effective is Azithromycin?

The medication is from a family of drugs known as macrolides.  They are designed to destroy the infection-causing bacteria which invades the mucosal surface of the areas it comes into contact with, such as the vagina.

Usually delivered via a 7-day course of treatment, Azithromycin has shown that, when taken correctly and as directed, is it a highly effective choice for men and women suffering from uncomplicated chlamydial genital infection when compared with other medications.

What is contained in Azithromycin?

The active ingredient is azithromycin at the required dose. 

  • The inactive ingredient are:
  • Microcrystalline cellulose
  • Pregelatinised maize starch
  • Sodium starch glycolate Type A
  • Colloidal anhydrous silica
  • Sodium laurilsulfate
  • Magnesium stearate

The tablets contain 0.36 mg of soya lecithin.  As such, if you have a soy allergy, please make your doctor aware of this. 

How does Azithromycin work?

Bacteria such as chlamydia trachomatis requires certain proteins in order to grow and multiply.  Without them, they cannot replicate, and as such, they will decrease in numbers.  Once this growth process is halted through the use of antibiotics such as Azithromycin, the bacteria will stop developing, and the body’s immune system will clear the remainder.


How long can I take Azithromycin for?

Azithromycin is usually prescribed for use in patients for between 1 and 10 days, depending on the reason for the course of treatment. The dosage will also vary.  As such, your doctor will be able to discuss the length of your treatment time. 

How should I take Azithromycin?

This is a prescription-only medication meaning it cannot be bought over the counter without a doctor’s recommendation. You can book an appointment with a Click Pharmacy doctor to discuss your symptoms or test results, and they will be able to advise you on how to take Azithromycin. 

You should always follow your doctor’s advise before proceeding with a course of treatment, but generally, the tablet will be taken once a day, swallowed down with water and with or without a meal. If you find that you suffer from nausea after taking medication, you may find this is eased by taking the tablet with food.

If you and your partner both have the infection, it is crucial you both take the treatment.

Side effects

There is a possibility of side effects inherent in the use of any medication. Common side effects of Azithromycin include:

  • gastrointestinal issues
  • nausea/vomiting

If you experience any of these side effects, then feel free to contact your doctor at Click Pharmacy to discuss your options. If they persist or worsen, or you find you experience an allergic reaction such as swelling of the tongue or face, then stop taking the tablets and seek medical help right away. 

There are also certain health conditions which can be negatively affected by the use of Azithromycin. These can include but are not limited to:

  • kidney problems
  • heart failure
  • low potassium/magnesium levels in the blood
  • hepatic disease
  • liver issues
  • certain cardiovascular concerns, including cardiac arrhythmia

Who should not take Azithromycin?

While Azithromycin is generally considered to be a safe medicine to take for most individuals, there are a few groups who should avoid the use of this particular medicine. Do not take Azithromycin if: 

  • You are allergic to Azithromycin or Macrolide antibiotics
