What is doxycycline?

Doxycycline is an antibiotic belonging to the tetracycline class. It is used to treat chlamydia, as well as other infections. It can also be used for the purpose of preventing malaria when travelling.

How does doxycycline work?

Doxycycline interferes with the bacteria’s ability to produce proteins, which are important for its survival. This prevents the bacteria from replicating, until it is no longer active.

How long does doxycycline take to work for chlamydia?

Treatment starts to work relatively quickly, and it takes around 48 hours for doxycycline to start working. However, it can take up to 7 days after having completed treatment, for your body to be free from chlamydia. This is why is it important to not have sex (including oral and anal sex) until you have finished the full 7-day course and your symptoms have gone. Any sexual partners should also be treated, and you should not have sex with them until they have finished their treatment too.

How effective is doxycycline for chlamydia?

Doxycycline is the first-line treatment for chlamydia recommended by BASHH. In clinical trials it cured 100% of urogenital infections, compared with 97% for azithromycin, and it is more effective than azithromycin for rectal infections.

How to take doxycycline?

Take One 100mg capsule twice a day for 7 days. Swallow each capsule whole with a full glass of water while sitting or standing upright. Do not take doxycycline just before going to bed, and stay upright for at least 30 minutes after taking it, as it can irritate the food pipe.

What happens if you miss a dose?

If you forget to take a dose, you should take it as soon as you remember. If you remember when it comes to taking your next dose, do not take two together. It is unlikely that missing one dose will impact the outcome of treatment, but you should inform your doctor or pharmacist.

A test of cure is not usually needed. However, you should retest if you missed doses or did not complete the course, had sex before finishing treatment, or your symptoms continue. Any repeat test should be done at least 3 weeks after finishing treatment. If you are under 25, a repeat chlamydia test between 2 and 6 months after treatment is recommended, as reinfection is common.

When you can have sex again

Do not have sex (including oral and anal sex) until you have finished the full 7-day course and your symptoms have gone. Any sexual partners should also be treated, and you should not have sex with them until they have finished their treatment too.

Doxycycline Alternatives

Azithromycin is an alternative for people who cannot take doxycycline. In clinical trials it cured 97% of urogenital infections.

Doxycycline ingredients

Doxycycline Side Effects

Like all medicines, doxycycline can cause side effects, although not everybody gets them.

Common (may affect up to 1 in 10 people): feeling or being sick (nausea or vomiting), headache, skin sensitivity to sunlight (which can cause sunburn more easily), rash, and allergic reactions such as hives or swelling.

  • signs of a severe allergic reaction, such as swelling of the face, lips, tongue or throat, sudden wheeziness, difficulty breathing, chest pain or a fast heartbeat
  • a severe headache, especially with blurred or double vision, loss of vision or vomiting, which can be a sign of raised pressure in the skull

  • liver problems
  • myasthenia gravis
  • systemic lupus erythematosus (SLE)
  • porphyria
  • a history of severe diarrhoea or bowel problems after taking antibiotics

You should discuss the use of doxycycline with your doctor if you are taking any of the following medication:

  • Anticoagulants such as warfarin that are used to thin blood
  • Antiepileptics
  • Certain prescription only medication used to help you sleep, such as those belonging to the barbiturate class
  • Certain drugs used in the treatment of migraine, such as ergotamine or methysergide
  • Some antibiotics used to treat tuberculosis, such as Rifampicin

  • Methotrexate
  • Retinoids such as isotretinoin used in the treatment of acne

Doxycycline and Pregnancy/Breastfeeding

Doxycycline is not suitable if you are pregnant, as it can slow down bone growth and stain the teeth of the developing foetus.

Doxycycline is present in breastmilk and should be avoided when breastfeeding.

Frequently Asked Questions

Nausea and vomiting are common side effects of doxycycline. If you vomit after taking doxycycline, you should carry on with the prescribed course. Although doxycycline can make you sick, partial absorption or missing one dose is unlikely to have an effect on the success of treatment. Try taking doxycycline after a meal to reduce feelings of nausea. If you throw up more than once, you should contact your doctor as you may need to try a different treatment.

Food does not affect the absorption of doxycycline and you can choose to take doxycycline on an empty stomach or after food. One of the possible side-effects of taking doxycycline is that it may make you feel slightly nauseas. If this is the case, you may find it helpful to take doxycycline after a meal.

Moderate alcohol consumption will not necessarily have an impact on the effectiveness of doxycycline, but it can make you feel slightly sick and dehydrated. You should avoid drinking large amounts of alcohol or avoid alcohol consumption altogether for the duration of your treatment if possible. Large amounts of alcohol consumption can reduce the effectiveness of doxycycline in treating chlamydia.

It can take 1-2 weeks for chlamydia symptoms to ease off. If your symptoms have not improved after 2 weeks, you should speak to your doctor.

You should visit your GP in the following circumstances:

  • You are experiencing an allergic reaction to doxycycline, such as skin irritation or diarrhoea
  • You have missed multiple doses
  • Your symptoms are persisting after the treatment course
  • You have had sexual contact with someone during treatment or within the 7-day period after having completed treatment
  • There is a possibility you may be pregnant
  • You are experiencing any unusual side-effects such as difficulty breathing, fever, swollen glands.

A test of cure is not usually needed. However, you should retest if you missed doses or did not complete the course, had sex before finishing treatment, or your symptoms continue. Any repeat test should be done at least 3 weeks after finishing treatment. If you are under 25, a repeat chlamydia test between 2 and 6 months after treatment is recommended, as reinfection is common.

Chlamydia is the most common sexually transmitted infection and can cause many long-term complications such as infertility and reactive arthritis. You should let your sexual partners know if you have had a positive diagnosis, so that they can receive treatment and avoid re-infecting you or others.

You should wait at least seven days after completing a full course of doxycycline treatment for chlamydia before engaging in unprotected sex. This allows the medication to effectively treat the infection and reduces the risk of transmitting it to sexual partners.

You should let your GP know if you are scheduled to receive a typhoid vaccination whilst on treatment, or within 72 hours after having completed treatment. This is because doxycycline can reduce the effectiveness of typhoid vaccinations.

Each patient must fill out a questionnaire individually as it assesses the suitability of doxycycline based on their medical status. The online consultation is intended to ensure that our service is safe for all those that we prescribe treatment for. Everyone must complete an individual consultation using their own account. Multiple orders under the same account will be rejected.

Your medical records are stored on a secure server which is not shared with anyone. Your order will be dispatched in a plain envelope that has no reference to what is inside.
