Dosage
Dose for infections and skin conditions
Your dose of doxycycline depends on why you are taking it.
The usual dose is 100mg to 200mg, taken once or twice a day.
You might take a lower dose, such as 40mg once a day or 20mg twice a day, for rosacea or gum infections.
Children younger than 12 years old may need to take a lower dose than adults.
The dose depends on your child's age and weight. If you're taking doxycycline more than once a day, try to space your doses evenly throughout the day.
Dose for malaria
You'll usually take 100mg once a day in the morning.
Important
Carry on taking doxycycline until you've completed the course, even if you feel better.
If you stop your treatment early, the infection could come back, or you may no longer be protected against malaria.
How to take it
If you're taking a lower dose of 40mg of doxycycline a day for rosacea or gum infections, take it at least 1 hour before food.
If you're taking a higher dose of 100mg or more for other types of infection, you can take it with or without food
