One Doxycycline 100mg capsule is to be taken twice a day for 7 days.
The capsules should be swallowed whole with plenty of fluid during meals. Space the doses evenly throughout the day and you must complete the course.
You should not take indigestion remedies, or medicines containing iron or zinc, 2 hours before or after Doxycycline as they can affect the absorption of the antibiotic, making it less effective.
Also, you should protect your skin from sunlight, even on a bright but cloudy day, and avoid sun beds or you may experience an unpleasant rash.
If you have been diagnosed with Chlamydia it’s highly recommended to inform any sexual partners, from the last 6 months, that they may be at risk in order that they can be screened and have treatment if required.
