COC’s are daily pills that contain two hormones, oestrogen and progesterone, which are similar to the ones naturally produced by your ovaries. Taking the pill at the same time every day not only can help prevent pregnancy but also has other benefits.

With typical use (forgetting a pill now and then), they’re about 90% effective. Setting reminders or combining the pill with a routine (like brushing your teeth) can help you remember to take it every day.
The COC is available in two forms – patches and tablets. This page focuses on the pill form.
One pill needs to be taken every day, ideally at the same time.Pill packs usually contain 21 active pills (with hormones) and some pill packs may also contain 7 inactive pills. During the inactive or pill-free week, you can expect to have your period.If you miss a pill the contraceptive effect may be altered. Each type of pill has different regimes on how to manage missed pills so follow the instructions in your pill pack.Most women tolerate COCs well, but some may experience mild side effects, especially in the first few months. These can include:
Nausea or upset stomachBreast tendernessSpotting between periodsMood changes (there is no clear consistent evidence that COC improves or worsens mood in those with pre-existing anxiety and mood disorders)HeadachesThese symptoms usually improve after a few months. If side effects persist, a different formulation of a combined pill may be helpful in alleviating symptoms. We offer free consultations prior to COC use – click below to book a consultation.
