How to take doxycycline

For prevention of malaria, doxycycline must be taken at a dose of 100mg (one capsule) daily, starting 1-2 days prior to travel and continued for 4 weeks after returning. It is important to swallow each doxycycline capsule whole with a glass of water. It is best to take your capsules at the same time each day, when standing or while sitting. If your stomach is upset, Doxycycline capsules can be taken with milk or a meal.

Pregnancy and breast-feeding

If you are pregnant, planning to become pregnant or are breast-feeding you should not use doxycycline and speak to your doctor.


Taking doxycycline can make your skin more prone to reactions from sunlight including sunburn. It is therefore advised to wear long clothing and a high protection sun screen whilst taking doxycycline.

Antibiotic related colitis

If you develop severe or prolonged or bloody diarrhoea during or after using doxycycline tell your doctor immediately since it may be necessary to interrupt the treatment. This may be a sign of bowel inflammation (pseudomembranous colitis) which can occur following treatment with antibiotics.

You should not take doxycycline if you suffer from Myasthenia Gravis or Systemic Lupus Erythematosus (Also known as just Lupus) as it may cause worsening of these conditions.
