What is Doxycycline?

Doxycycline is an antibiotic that is used to treat a variety of bacterial infections. These include urinary tract infections, acne, gum disease and the sexually transmitted infections Chlamydia, Mycoplasma Genitalium and Ureaplasma Urealyticum. Doxycycline has been used to treat Gonorrhoea in the past but most strains are now resistant to Doxycycline so alternative antibiotics are used. Doxycycline is sometimes sold with the brand name Vibramycin but can also be sold generically as Doxycycline.

Doxycycline can be taken as a malarial prevention medication. It is normally taken if you are travelling to areas where there is a high risk of falciparum malaria being resistant to chloroquine. If your doctor prescribes Doxycycline for malaria prevention, you would normally take it two days before your trip to the area considered to be high risk and for 4 weeks after leaving.

How does Doxycycline work?

Doxycycline is part of a class of antibiotics known as tetracyclines. Doxycycline works by blocking the production of certain proteins. Without those proteins, the bacteria are unable to grow, replicate or multiply. Without the proteins they either die or can be killed off easily by the immune system.

Are there any side effects associated with Doxycycline?

Most people will take Doxycycline and notice no side effects. However where there are side effects, the most common are diarrhoea, nausea and vomiting. It can also intensify the effects of UV light, so people taking this medication should avoid the sun or use a high factor sunscreen.

Like other antibiotics, Doxycycline can also interfere with the contraceptive pill so additional protection is advised while taking this medication.

When should you not take Doxycycline?

It is recommended that Doxycycline (along with certain other antibiotics) should not be taken with aluminium, magnesium or calcium-based antacids. This is because they would cause the medicine to bind to the intestines and prevent it being absorbed.

It is also not suitable for people with liver or kidney problems, porphyria or women who are pregnant or breastfeeding.

How quickly does Doxycycline clear up Chlamydia and NSU?

Doxycycline is usually given as a 7-day course of treatment. After treatment, patients should wait 7 days until having unprotected sex with their partner, as long as both partners have been treated for the infection. Otherwise it is likely the infection will just be passed back and forth.

If you have tested positive for a sexually transmitted infection or if you have been told that your symptoms are likely to be NSU, please click for a free consultation and one of our doctors will consider an appropriate treatment.
