or pharmacists for help.
How much to take
Your doctor or pharmacist will tell you how many capsules you will need

For treating infections, the usual dose of doxycycline is two 100 mg
capsules on the first day, followed by one 100 mg capsule each day from
then on.
For controlling acne, the usual dose is one 50 mg capsule each day.
For the prevention of malaria, the usual dose is one 100 mg capsule each
day, commencing two days before entering the malarious area, during the
visit, and for two weeks after leaving the area.
Your doctor may ask you to take a different dose, depending on your
condition and how you react to the medicine.
How to take it
Swallow the capsules whole with a full glass of water or milk while
sitting or standing upright.
Do not lie down immediately after swallowing Doryx.
It is important to stay upright, for example sitting, standing or
walking around for at least half an hour after swallowing your capsule.
This is to help avoid irritation to your food pipe, also called the
oesophagus.
Do not chew the capsules.
When to take it
Take your medicine at about the same time each day (usually in the
morning).
Taking it at the same time each day will have the best effect. It will
also help you to remember when to take it.
Take your medicine during or immediately after a meal.
If taken on an empty stomach, it may cause stomach upset.
How long to take it
Continue taking your medicine until you finish the pack or for as long
as your doctor recommends.
Keep taking this medicine for the full time of treatment 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.
For treating infections, Doryx is usually taken for one to two weeks.
For controlling acne, Doryx is normally taken over a period of 12 weeks.
For preventing malaria, Doryx is recommended to be taken for up to a
maximum of 8 weeks. However, your doctor may prescribe Doryx for longer
periods.
If you are not sure how long you should be taking this medicine, talk to
your doctor.
If you forget to take it
If it is almost time for your next dose, skip the dose you missed and
take your next dose when you are meant to.
Otherwise, take it as soon as you remember, then go back to taking your
medicine as you would normally.
Do not double a dose to make up for the dose you have missed.
This may increase the chance of you getting an unwanted side effect.
If you are not sure what to do, ask your doctor or pharmacist.
