What is Azithromycin?

Azithromycin is a commonly prescribed first-line treatment for chlamydia. It belongs to a group of antibiotics called macrolides which are effective in eliminating chlamydia trachomatis, the bacteria responsible for chlamydia infections.

What is Doxycycline?

Doxycycline is the other first-line antibiotic treatment for chlamydia. This antibiotic is from the group called tetracyclines which is also effective in killing chlamydia trachomatis, the bacteria responsible for chlamydia infections.

How do Azithromycin and Doxycycline work?

Both treatments for chlamydia work by stopping the bacteria that causes chlamydia from being able to continue growing and multiplying anywhere in the body.

Are they both effective?

Both treatments are around 95% effective in treating chlamydia after one course of treatment. Treatment failure is rare and often the result of failure to complete the course of antibiotics properly.

What Alternatives are there for chlamydia treatment?

Azithromycin and Doxycycline are the first-line treatments given for chlamydia infections. If you have an allergy to these types of treatments, you should discuss with your regular GP about using alternative antibiotics. It is important to note that no natural or alternative herbal treatments have been proven clinically effective for treating chlamydia.

What is Chlamydia?

Chlamydia is a bacteria infection. The bacteria is known as chlamydia trachomatis and is spread through unprotected sexual contact. As such it is known as a sexually transmitted infection or STI. 

What does chlamydia look like?

Chlamydia can have no symptoms in both men and women. When chlamydia does have symptoms they generally show for men as pus-like discharge from the penis, burning upon urination, and sore testicles. For women chlamydia shows as vaginal discharge, painful sex, burning upon urination, abdominal pain and spotting before period.

How do you get chlamydia?

Chlamydia is spread through contact with fluid infected with the bacteria chlamydia trachomatis. This can happen through vaginal, oral or anal sex.

Is chlamydia curable?

Yes, thankfully chlamydia is treated and cured with antibiotics. Some bacteria may be more resistant to antibiotics and harder to treat but currently, all can be treated with various antibiotics.

Can you get chlamydia from oral sex?

Yes, during oral sex you can come into contact with fluids infected with the bacteria chlamydia trachomatis which can cause infection./

How long can you have chlamydia before it causes damage?

This depends on how quickly and if the chlamydia spreads. Chlamydia in women can spread to the fallopian tubes and cause pelvic inflammatory disease. Untreated chlamydia here can cause permanent scarring which leaves women at a higher risk of infertility. 

For men, untreated chlamydia can travel to the testicles and cause inflammation and long-lasting pain in the tube that connects the penis to the testicles. This condition is known as epididymitis.

Chlamydia should be diagnosed and treated as soon as possible to avoid long-lasting damage to the reproductive system.

Does chlamydia go away on its own?

No, it is very unlikely your body’s immune system will be able to fully clear a chlamydia infection. It may be able to briefly make the systems better, however, you still remain infected and infectious to others. You should seek testing and treatment as soon as you suspect a chlamydia infection to avoid permanent damage to the reproductive system.

Can you get chlamydia by kissing?

No, chlamydia is spread through contact with infected fluids. These infected fluids are usually in the genitals. You cannot get chlamydia from kissing, sharing towels, hugging, coughing, sneezing or toilet seats.

How to use Azithromycin?

To treat chlamydia, 1000mg of Azithromycin is taken as a single dose. This dose stays in the body for a long time to continue to treat the infection. For this reason, it is recommended to avoid any sexual activity and sexual contact for a least 7 days after the dose is taken. Sexual partners must also be treated in order to avoid reinfection.

How to use Doxycycline?

To treat chlamydia, 100mg (one tablet) of Doxycycline is taken TWICE daily for SEVEN days. Like Azithromycin it is recommended that you abstain from sex while being treated with antibiotics during the 7-day course.


Do not take Azithromycin if you have had any allergic reactions to macrolide antibiotics. Do not take Doxycycline if you have had any allergic reactions to tetracycline antibiotics.

If you get any allergic reactions to Azithromycin or Doxycycline including difficulty breathing, diarrhoea that does not resolve, severe or itching rash or swelling of face, lips or neck. Seek our emergency healthcare immediately.
