Doxycycline Chlamydia Treatment

What is Doxycycline used for?

Doxycycline belongs to the class of macrolide antibiotics, and is commonly used to treat different forms of infection caused by bacteria. It does so by stopping bacteria from multiplying, thus preventing the spread of the infection and its chance to continue thriving in your body and causing you discomfort of pain. This anti-biotic can be used to battle with a range of bacteria such as those responsible for the infection of skin, ears and respiratory systems, as well as sexually transmitted diseases such as chlamydia.

Doxycycline Dosage

At Medicine Direct we sell Doxycycline in 400mg strength tablets in a 14 tablet packet size.

Doxycycline 400mg

This is the most commonly prescribed strength of Doxycycline used in treatments. The dosage necessary of this strength varies according to your infection. For most infections, you will be advised to take two 400mg tablets twice a day for 7 days.

How should you take Doxycycline 400mg?

As it is a tablet, you should take Doxycycline with a glass of water. You are able to consume the medicine before or after eating. Do not take a double dose of the antibiotic if you have forgotten a previous dosage. However, if you remember in time, take the tablet as soon as possible. If you have to skip a dose it may be possible to just continue the course and finish a day later. Contact your doctor or pharmacist to discuss what your best options are should you find yourself in that situation.

You must not stop taking Doxycycline once you have started your course of the antibiotic. If your infection is not fully treated, it may return and be more difficult to treat.

Please be aware that you should not take Doxycycline if you are:

  • Allergic to Doxycycline dehydrate, erythromycin, any form of macrolides or ketolide antibiotics
  • Allergic to any other ingredient contained in this medicine

Furthermore, there are some situations in which Doxycycline may not be suitable for a patient. You must tell your doctor or pharmacist if you have ever suffered with any of the bullet points below so that they can assess whether Doxycycline will be appropriate to prescribe to you:

  • Suffer from severe liver or kidney problems
  • Serious heart problems
  • Low levels of magnesium or potassium in their blood
  • Develop signs of a further infection elsewhere
  • Taking medicine to treat migraines which contains ergotamine because these two medicines should not be consumed together
  • Suffer from myasthenia gravis (muscle weakness)
  • Have neurological or mental problems

Below are the standard recommendations of how to administer Doxycycline in accordance to the infection:

Doxycycline 400mg for Chlamydia Treatment

You must not have sexual intercourse (vaginal, oral or anal) for at least a week after this as you will run the risk of spreading chlamydia or infecting a partner. If there are still symptoms or you did not complete the course accurately you must return to your clinic and doctor to seek further advice.

Respiratory Infections

Usually, doctors tell patients to take Doxycycline 400mg twice a day for 7 days. For anyone under 46kg, the doctor will have to assess an appropriate dosage to their weight and height.

Lyme Disease

To treat Lyme disease Doxycycline must be taken in 500mg doses once daily for 7 days. Doctors will usually want to see you after the course of medication to check your symptoms and assess whether it has been successful in treating the disease.


Your doctor will generally advise you to initially consume 500mg of the antibiotic each day for at 2 days (at least), and then depending on the success you will be recommended on continuing this administration of the medicine for a further 7-10 days.


The general recommendation to treat the infection which causes Bronchitis is to take 500mg once a day for three days.

For the treatment of all other infections follow the instruction given to you by your doctor or pharmacist.

Doxycycline Side effects
