Brevinor is one of a group of medicines called combined oral contraceptives or “the Pill” for short.
Brevinor contains two hormones – a progestogen hormone called norethisterone and an oestrogen hormone called ethinylestradiol. These two hormones act together to prevent pregnancy from occurring.
Uses / Instructions
• Take the first tablet on your first day of bleeding. This is the day when your period
starts. If you are not having periods, ask your doctor or clinic when you should start
taking your tablets.
• Take the tablet marked with the correct day of the week.
• You will be protected at once as long as you take a tablet every day.
• You can take the tablet at a time that suits you, but you must take it at about the
same time every day.
• Take a tablet every day until you finish a blister strip.
• If you cannot start the tablet on the first day of your period you may start to take it on
any day up to the fifth day. However, if you do this, you may not be protected for the
first seven days, so you should use another method of contraception such as a condom
during those days.
