About Doxycycline

Doxycycline is an antibiotic taken twice daily for 7 days to treat chlamydia infection.

  • Avoid sexual contact whilst taking doxycycline and for 7 days afterwards, until no longer infectious.
  • People with a positive chlamydia test and their sexual partners should be treated, at the same time if possible.
  • Tests take 5 weeks to go negative after chlamydia has been successfully treated.

Doxycycline antibiotic is prescription only medicine – our doctors will issue the prescription online direct to our pharmacy. The medicine is then posted recorded delivery.

For background information about chlamydia please see chlamydia information page.

Alternative antibiotic

Azithromycin is no longer the recommended first choice treatment of chlamydia - see latest BASHH guidance. Azithromycin and ofloxacin can be used by people who cannot take doxycycline.

Side effects and cautions

The most frequently seen side effects are nausea, vomiting, diarrhoea, and acid type indigestion, heartburn, rash/itching, and vaginal itching.

Other side effects are rare. Doxycycline can cause light sensitivity. Strong sun and sun beds should be avoided whilst doxycycline is being taken.

For a full list of side effects and information about taking doxycycline, including interactions with other medication, see the patient information leaflet on doxycycline.


Doxycycline should not be taken at the same time as antacids or milk as these can reduce absorption. Not advised during pregnancy and breastfeeding.

Doxycycline 100mg

Unfortunately this preparation seems to give joint pain as it attacks cartilages.

Dr Fox response:
Thank you for your review. our doctors advise joint aches can be caused by taking doxycycline as a side effect and would not expect this to be formulation specific. They suggest using a different recommended antimalarial tablet going forward and to discontinue taking doxycycline. If the pain does not settle then it is important to discuss with your doctor.
