What is Erythromycin and how does it treat chlamydia?

Erythromycin is an antibiotic used to treat bacterial infections. Erythromycin tablets work by preventing bacteria from producing their essential proteins. Without these, the bacteria is unable to grow and replicate and will eventually be destroyed by your immune system. Erythromycin is a broad-spectrum antibiotic which means it can work on a number of different bacteria. Doctors sometimes prescribe a particular dosage to treat chlamydia. Being a broad-spectrum antibiotic, there may be some, undesirable erythromycin side effects which will be explained further later.

Erythromycin Dosage and How to Take It

Erythromycin (capsules, tablets): When taking erythromycin for a chlamydia infection you should consume 500mg orally, four times a day, for 7 days.

Erythromycin ethylsuccinate: When taking erythromycin ethylsuccinate for a chlamydia infection you should consume 800mg orally, four times a day, for 7 days.

This medicine can be taken either with or without food. However, nausea is a common problem with erythromycin, particularly if it's taken on an empty stomach, so you might want to take it with food or milk. Bottles of suspension (erythromycin ethylsuccinate) should be shaken thoroughly before measuring out a dose.


Antibiotics work best when the amount of medicine in your body is kept at a constant level, so try to take your erythromycin tablets at the same time each day. Do not stop taking this medicine before the course is finished, even if you stop experiencing symptoms of chlamydia. Stopping the treatment too early may allow bacteria to continue to grow, causing relapse.

Erythromycin Side Effects

You might want to be aware of the following erythromycin side effects when taking this medicine:

  • Nausea and vomiting
  • Abdominal pain
  • Diarrhoea
  • Rashes, hives, itching or other allergic skin reactions
  • Disturbance of liver function
  • Jaundice (yellowing of the skin and eyes)
  • Pancreatitis (inflammation of pancreas)
  • Reversible loss of hearing
  • Abnormal heart beat (arrhythmias)
  • Inflammation of the large intestine (colitis)

In addition to this, extended use of any antibiotic can lead to an overgrowth of other organisms which aren't susceptible to the antibiotic. So you may find yourself noticing fungi or yeast infections (such as thrush) with extended high dosage erythromycin use.

Women Taking Erythromycin

Women who contract chlamydia while pregnant are often prescribed erythromycin as it is milder than most other antibiotics used for treating chlamydia.

Who Should Not Take Erythromycin

Erythromycin isn't for everyone, and some people should not be prescribed erythromycin tablets to treat their chlamydia infection.


If any of the following applies to you, you will not be prescribed erythromycin/you will only be prescribed erythromycin in special circumstances:

You are allergic or sensitive to any of the medicines ingredients
You have liver problems
You have kidney problems
You have myasthenia gravis
You are taking or have taken cytochrome P450 enzyme inducers within the last 2 weeks.

Erythromycin Drug-to-Drug Interactions

In addition to the erythromycin side effects mentioned above, you should also be aware of certain drug-to-drug interactions that can take place between your erythromycin tablets and any other medication you happen to be taking.

As a general rule, erythromycin tablets should not be taken by anyone using the following medications (due to adverse side effects):

  • amisulpride

  • cisapride
  • ergotamine
  • eletriptan
  • dihydroergotamine
  • dronedarone

  • mizolastine
  • moxifloxacin
  • pimozide
  • saquinavir
  • sertindole
  • simvastatin
  • terfenadine
  • tolterodine
  • vinblastine

In addition to that, a high erythromycin dosage may reduce or breakdown certain medicines you are taking. Which may cause their side effects to become more prevalent. It is not advised to take erythromycin if you're also taking any of the following medication:
