How to take Doxycycline

Doxycycline should only be taken if prescribed by a registered doctor.

The usual dose of doxycycline is one 100mg capsule daily. You should start the course two days before you travel, and take them every day that you are in a risk region and for four weeks after you leave the area.

Doxycycline can cause the skin to be hypersensitive to the sun, so special care should be taken to avoid sunburn by covering up or using high factor sun creams in strong sunlight.

Is Doxycycline suitable for me?

Doxycycline is not suitable for pregnant or breastfeeding women, children under 12 (because there is a risk of permanent tooth discolouration), and people who are sensitive to tetracycline antibiotics or those who have liver problems.

What are the side effects of Doxycycline?

Doxycycline, like all medicines, can cause unwanted side effects, although it’s worth bearing in mind that not everyone experiences these. Possible side effects are nausea, vomiting, diarrhoea, dysphagia, and oesophageal irritation. Other rare side-effects include hepatotoxicity, pancreatitis, blood disorders, photosensitivity, hypersensitivity reactions (including rash, exfoliative dermatitis, Stevens-Johnson syndrome, urticaria, angioedema, anaphylaxis, and pericarditis), anorexia, dry mouth, flushing, anxiety, and tinnitus. Headache and visual disturbances are also possible.

Doxycycline will not normally interfere with the effectiveness of oral contraceptive pills unless it causes diarrhoea or vomiting.
