For treating infections, the usual dose of doxycycline is 100 mg twice a day for the first day, followed by 100 mg once a day from then on.
For controlling acne, the usual dose is 50 mg (taken as one 50 mg tablet or half a 100 mg tablet) once a day.
For the prevention of malaria, the usual dose is 100 mg once a day, commencing two days before entering the malarious area, during the visit, and for two weeks after leaving the area.
Travel medicine advice may change from time to time and it is best to ask your doctor or pharmacist for the most up to date information about which antimalarial medicines are suitable for certain areas, and for how long you need to take the medicine after leaving the malarious area.
You should ensure that you take your medicine with unfailing regularity for the whole time you are there and after leaving the malarious area, as parasites may still emerge from the liver for up to four weeks after the last possible exposure to infection.
Do not stop taking your medicine or change your dosage without first checking with your doctor.
Swallow the tablets whole with a full glass of water or milk while sitting or standing upright.
Do not crush or chew the tablets.
Do not lie down immediately after swallowing doxycycline.
It is important to stay upright, for example sitting, standing or walking around for at least half an hour after swallowing your tablet. This is to help avoid irritation to your food pipe, also called the oesophagus.
Take your medicine during or immediately after a meal, at about the same each day (preferably in the morning).
If you take it on an empty stomach, it may cause stomach upset.
Avoid taking doxycycline at bedtime.
Keep taking this medicine for as long as your doctor has told you, even if you begin to feel better after a few days.
If you do not complete the full course prescribed by your doctor, the infection may not clear completely or your symptoms may return.

Your doctor may prescribe doxycycline for longer periods.
Make sure you have enough to last over weekends and holidays.
