Combined Oral Contraception (COC)
The combined pill is usually just called the pill. It contains two hormones - oestrogen and progesterone.
How effective is it?
If the pill is taken according to the instructions it is over 99% effective.
This means that less than 1 woman in a 100 will get pregnant in a year.
How does it work?
The main way the pill works is to stop the ovaries from realising an
egg each month (ovulation).
Where can I get the pill?
In Dumfries and Galloway you an get the pill from your GP, a Family
Planning and Sexual Health Clinic and a C2U
clinic if you are under 20.
Can anyone use the pill?
Not everyone can use the combined pill. Although there are some medical
conditions that would mean you should not take the pill, decisions
often depend on a combination of age, smoking, the severity of
any medical condition, whether there are other health problems and
sometimes your family history of illness. Each woman’s situation
is different and your doctor or nurse will be able to advise you.To

or acne.

certain age?

medical history then there would be reason to stop the pill. In fact if
you are healthy, do not smoke and there are no medical reasons for you not
to take the pill you could take it until the age of 50.

If you have an Everyday Pill (packs that contain inactive pills) please speak to your nurse or doctor about what to do if you miss pills.

Keep taking your pills as usual and use an extra method of contraception, such as condoms, while taking the antibiotics and for seven days afterwards.
