Any sexual contact without a condom may pass on STIs.
Some things make the pill less effective. That means it doesn't work properly!
-- Not taking it properly.
-- Taking it more than 3 hours late (or 12 hours if you're taking Cerazette)
-- Vomiting within two hours of taking it.
-- Very severe diarrhoea.
-- Some prescription and complementary medicines (such as St John's Wort).
Protect Yourself
The combined pill is a small tablet containing the hormone progestogen.
You take these pills according to the doctors or health advisors instructions.
Progestogen makes the mucus around the cervix thicker, which makes it difficult for sperm to get into the womb. It can also make it difficult for an egg which has been fertilised to implant in the womb. In some women it stops ovulation (the release of an egg).
The combined pill is 99% effective when used correctly.
