Combined contraceptive tablets

What does it do?

Combined contraceptive tablets contain the hormones oestrogen and progestogen. They are used to prevent pregnancy or regulate your period. They may also be used to treat polycystic ovarian syndrome (PCOS) or acne.

Before you start

  • Tell your doctor if you have heart, liver, or gallbladder problems, migraines, or high blood pressure.
  • Tell your doctor if you have had a blood clot or stroke, or if you smoke.
  • Women taking combined contraceptive tablets may have a small increased risk of breast cancer. Tell your doctor if you, or someone in your family, has ever had breast cancer.

How should you take it?

Your pack has 21 active hormone tablets. Some packs also have 7 inactive tablets.
When you first start, it is best to take a hormone tablet on the first day of your period. However, if you start within 5 days of the first day of your period, you are still protected from pregnancy straight away. If you start more than 5 days after the first day of your period, you will need to use condoms (or don’t have sex) for the next 7 days.
Take your tablet at the same time each day.
You can choose to take your tablets "continuously" (take the 21 hormone tablets, then start the next pack, skipping the 7 inactive tablets or your 7-day break). With this option you won't get a period and you are protected from getting pregnant unless you forget more than 8 tablets in a row.
See separate information sheet if you are taking Qlaira®.

What if you forget a dose?

If you miss 1 hormone tablet (over 24 hours late): take it as soon as you remember, then take the next hormone tablet at the usual time – even if this means taking 2 tablets together.

If you miss 2 or more hormone tablets: take the last tablet you missed as soon as you remember - even if this means taking 2 tablets together. Then take a hormone tablet for the next 7 days at the usual time. You need to use condoms (or don’t have sex) during these 7 days. If there are less than 7 hormone tablets left in the pack, finish these and then start your new pack straight away (skip the 7 inactive tablets or your 7-day break). If you are in the first week of your pack and you have had unprotected sex, you may need emergency contraception. Check with your health professional.

If you are unsure what to do, always check with your health professional.
