What is Doxycycline?

Doxycycline (sometimes referred to as Doxycycline hyclate) is a tetracycline antibiotic that you can buy online at OnlineClinic. Its function is to attack bacteria in your body. It is mainly prescribed for sexually transmitted infections (STIs) for people who have experienced side effects with some of the other higher dose medications available.

This medication is able to treat and cure chlamydia, non-specific urethritis and ureaplasma in a single course for the majority of people. As it is a more gradual form of treatment, it's also much less likely to cause side effects, but effective in treating stubborn bacterial infections.

It can also be prescribed for non-sexual conditions, such as Rosacea, and can even be prescribed to help treat malaria.

Short facts about Doxycycline
How to take

Take twice a day for a seven day period, until completion of your course.

How it works

Doxycycline targets the bacterium responsible for the infection by preventing the cells from multiplying. It does this by stopping them from producing protein.


Doxycycline is a proven medication[1] with cure rates of above 90% for Chlamydia and other bacterial infections.


Doxycycline is available to buy online in a dose of 100mg and at 14 capsules at a time.

Side effects

Doxycycline is renowned for not causing many side effects. However, some people do report experiencing headaches, nausea, and diarrhoea.

How does Doxycycline work?

Doxycycline directly attacks the bacterial cells and affects their ability to produce protein. This protein plays a part in the general function and production of the pathogen cells, meaning that, if this is inhibited, it prevents these cells from multiplying until it eventually results in the bacteria dying.

How to take Doxycycline?

Before you buy Doxycycline capsules, ensure that you read through the below instructions. Doxycycline is simple and easy to use, and has a high level of efficacy. Below are a few pointers to show you how best to take this medicine.

  • Doxycycline should be taken at the same time every day, twice a day for a total of seven days (or longer if advised by your doctor).
  • It's important that you keep on taking it, even if you start feeling better and that you wait at least two weeks after you've completed treatment to do an STI test to ensure that the infection has gone completely.
  • Doxycycline should be taken with a full glass of water.


You can buy Doxycycline in a standard dose of 100mg, which should be taken as prescribed by your doctor. All the ingredients have been specifically calculated by the manufacturer to ensure high effectiveness, and low chances of experiencing side effects.

Side effects and precautions

Side effects

One of the reason that Doxycycline is so commonly prescribed is the fact that it's able to treat infections effectively without often causing side effects, however, it still is a prescription medication, so side effects are still possible. The most frequently experienced side effects patients report aren't normally serious, and can potentially include headaches, nausea, diarrhoea, skin rashes or dizziness. Speak to your doctor immediately if you start to notice anything more serious or if these possible side effects persist or become worrisome.


Whilst experiencing an adverse reaction is unlikely, it's important to be aware that certain medications can interact badly with other ones you are taking. It's always wise to read the patient information leaflet, which is included with your medication and is available for download on this page.

  • You should not take Doxycycline if you are allergic to any tetracycline antibiotic
  • You need to talk to your doctor is you are pregnant or breastfeeding
  • Try to avoid taking any other antibiotics with Doxycycline unless your GP has informed you that it is OK to do so
  • You should avoid antacids, calcium and iron supplements, and oral birth control pills when taking Doxycycline

Note: Decisions about treatment are for both the prescriber and the person to jointly consider during the consultation. However, the final decision will always be the prescriber’s.
