What is Doxycycline?

Doxycycline is a broad-spectrum antibiotic used to treat a range of bacterial infections. It is commonly used as an antimalarial when travelling abroad to areas where malaria is known to be prevalent.

How does Doxycycline work?

Doxycycline is a tetracycline antibiotic, but it is often used for malaria prevention. Malaria is not a bacterial infection, but a parasitic one. Doxycycline works by preventing the parasites from invading the red blood cells giving the immune system more time to fight off the infection before you notice any symptoms. Doxycycline does not prevent malarial infection, but it does prevent the development of the disease if you are infected with the malaria parasites. 

How effective is Doxycycline?

Doxycycline is widely used because it is an effective treatment for a range of bacterial infections. However, overuse has lead some strains of bacteria to develop resistance to Doxycycline. Your doctor may choose to take a tissue sample from the infected area to ensure the bacteria causing the infection are susceptible to Doxycycline. If you are planning to use this medication as an antimalarial, check online or with a doctor if Doxycycline provides adequate protection from malaria in the area/s you are travelling to.


Active ingredients

The active ingredient in Doxycycline is doxycycline hyclate, an antibiotic used to treat a range of infections.

Inactive ingredients

The inactive ingredients in Doxycycline are sucrose, maize starch, crospovidone, basic butylated methacrylate copolymer (Eudragit E100) and purified talc.

Please Note: Inactive ingredients can vary between different brands of generic doxycycline.


How to take Doxycycline for malaria prevention

When taking Doxycycline for malaria prevention, you should start the course of medication 2 days before arriving in the malaria zone. The recommended dose is 1 capsule per day at around the same time each day. You should continue to take 1 capsule per day for 4 weeks after leaving a malaria zone. 

Doxycycline dosage

For adults and children over the age of 12, the recommended dose is 200 mg on the first day of treatment, then 100 mg each day for the duration of the course. The length of the course will depend on the type of infection you have, so follow the directions given to you by your doctor.

When to start taking Doxycycline

You should start taking Doxycycline 2 days before travelling to a malaria zone.

When to stop taking Doxycycline

You should continue to take the recommended dose of Doxycycline for 4 weeks after leaving a malaria zone.

What if I forget to take a dose?

If you're taking Doxycycline for malaria prevention, you should try to take it at the same time every day. If you do forget to take Doxycycline at the right time, you should take it as soon as possible and make sure you take the following dose at the correct time. If you miss a dose completely, you should not take a double dose, instead you should contact a medical professional for advice and take additional precautions against malaria i.e. staying inside more - especially at night, using mosquito nets etc. 

Should you take Doxycycline with food?

Doxycycline can be taken with or without food. If you find that you feel nauseous, you may find it easier to take Doxycycline with or directly after a meal. However, avoid taking this medication directly with dairy products such as milk or yoghurt, as these can reduce its effectiveness.
