How To Take Doxycycline
Take the capsules twice a day (12 hours apart if possible) with food.
Take the capsules with a full glass of water because they can cause irritation if stuck in the throat.
You must not have sex for 7 days after starting treatment. If a partner is also being treated, you must not have sex until their 7 days is also complete. This means no sex even with a condom, and no oral sex.
You can read the Doxycycline Summary of Product Characteristics for more detailed information.
The effectiveness of the contraceptive pill after the ‘no sex’ 7 days may be reduced if you develop vomiting
If this occurs, continue taking your pill as usual but follow the advice for your pill about using extra precautions (e.g. condoms) when you miss pills or have vomiting
If you are concerned that you might be at risk of pregnancy from unprotected sex you can access emergency contraception.
