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 26 active hormone tablets and 2 inactive tablets.
When you first start, take a hormone tablet on the first day of your period so that you are protected from pregnancy straight away. If you start at any other time you will need to use condoms (or don’t have sex) for the next 9 days.
Take your tablet at the same time each day.

What if you forget a dose?

The missed dose instructions for Qlaira® are slightly different compared to other combined contraceptive tablets. See the company's information at the Medsafe website (
