Doxycycline capsules are a prescription-only medication used to treat chlamydia. Doxycycline treats more than 90% of cases with a seven-day supply. Doxycycline works by hindering bacterial protein synthesis.
Without proteins, bacteria can't reproduce effectively, preventing them from growing. Suitable for adults and children over 12 years old and contains 100mg of Doxycycline (a bacteriostatic).

Doxycycline 100mg capsules are an antibiotic used in the treatment of chlamydia. Symptoms, if any, begin to clear after a few days, as long as you complete the entire course of treatment. You should also avoid sexual intercourse while using the antibiotics.
When to Use Doxycycline for Chlamydia?
Chlamydia typically occurs when you have unprotected sex with an infectious person, share sex toys, or when a pregnant woman passes the infection onto her child.
Doxycycline is a first-line treatment for chlamydia infections. It's used for standard chlamydia without complications and rectal chlamydia.
Women with genital chlamydia are more at risk of asymptomatic rectal infections, and Doxycycline is considered to be more effective than Azithromycin.
Individuals with a severe chlamydia infection (also known as Lymphogranuloma Venereum (LGV) can also benefit from more intensive antibiotic treatment.
Some people are at risk of chlamydia and gonorrhea co-infections, and Doxycycline is also used in combination with other antibiotics to eliminate the infection.
Age Restrictions for Doxycycline for Chlamydia
As an antibiotic, doxycycline is generally suitable for adults and children over 12, depending on a healthcare professional's advice. However, younger children have a higher risk of tooth discolouration, which is why the UK recommends against using it to treat people under 12.
Most cases of chlamydia affect adults, but a mother may pass it on to her unborn baby. There are alternative treatments available for children.
How to Use Doxycycline for Chlamydia Treatment?
Chlamydia is one of the most common sexually transmitted infections, but Doxycycline is a highly effective treatment - as long as you use it correctly.
Most GPs will prescribe a seven-day dose and issue these instructions:
- Take one 100mg pill twice daily, leaving 12 hours between doses whenever possible. People with severe chlamydia may require a higher dosage.
- Continue with the treatment course, even if your symptoms disappear after a few days.
- Always drink plenty of water when you take the pill to avoid throat irritation. It's also a good idea to eat something.
- Drinking alcohol can reduce the antibiotic's ability to work and may increase the risks of side effects. It's best to avoid it while using Doxycycline.
- Please avoid sexual intercourse and activity while taking Doxycycline. You should also inform previous partners, as they might need treatment too.
- Never double up on doses. If you miss a dose, take it when you remember or skip the missed dose.
Who Should Avoid Using Doxycycline to Treat Chlamydia?
Doxycycline is one of the best treatments available for chlamydia, but there are some cases when you definitely shouldn't use it. These include:
- When Pregnant or Breastfeeding: Using Doxycycline while pregnant can impact the baby's bone development. Breastfeeding women should also avoid it as the antibiotic can cause future tooth staining in their baby.
- Young Children: In most cases, a doctor won't prescribe Doxycycline in the UK for children under 12 - unless they feel that a child over 8 can benefit from it. However, children under 8 should never use Doxycycline.
- Allergies: If you're sensitive or have an allergy to tetracyclines, you must avoid using Doxycycline, as it can cause an allergic reaction.
Precautions for Doxycycline to Treat Chlamydia
If you have a medical condition or are taking any prescribed/OTC treatments, please speak to your doctor before using Doxycycline.
This includes people with severe kidney or liver disease, systemic lupus erythematosus, and colitis.
