Brevinor

Most women choose to take 1 pill daily for 21 days, then have a 4 or 7-day break before starting the next pack. During this break you’re likely to have a withdrawal bleed. This is like a period but isn’t one.  

You can also take Brevinor as follows: 

• Tricycling: Take 1 pill daily for 9 weeks without a break. After 9 weeks (3 packs of pills) take a 4 or 7 day break and then start the cycle again.  
• Continuous use: Take 1 pill daily without a break.  
• Flexible extended use: Take 1 pill daily for at least 21 days. If you get bleeding that’s unacceptable to you, take a 4-day break. On the fifth day start taking the pill daily again and don’t have another break for at least 21 days. 

Many women do not experience any side effects, however some will. These can include headaches, feeling sick, mood swings, and breast discomfort. Rarely, some women develop blood clots. This pill carries a slightly higher risk of blood clots than others. If you have any concerns, send us a message via your Patient Record.

For full information on side effects and correct use, see the patient information leaflet. If any side effects concern you, contact us via your Patient Record.

When taken correctly, Brevinor is 99% effective in preventing pregnancy. If it’s not always taken correctly roughly 9 out of 100 women will get pregnant.

If you are vomiting or have severe diarrhoea you may not be protected against pregnancy. If this happens, continue to take the pill as usual but use a condom whilst you're ill. If this continues for more than 24 hours you should follow the same steps as a missed pill. 

Please note – you should only start Brevinor if you’re sure you’re not pregnant.  

If you start using Brevinor on days 1-5 of your period, you should be protected from pregnancy immediately, provided you don’t have a short or irregular menstrual cycle. 

If you start Brevinor after day 1 and have short/irregular menstrual cycle you’ll need to use condoms for 7 days if you have sex. Your clinician will be able to advise if you need to use extra contraception in the first 7 days if you have sex.  

This depends on when and how many pills are missed. Missing one pill, at any time, does not compromise contraception. Missing two or more pills or starting a new pack late might affect your contraceptive cover.

Up to 48hrs since your last pill – take your next pill as soon as you remember and continue the rest of the pack as usual. This might mean you need to take 2 pills on 1 day.

More than 48hrs – this depends on when you last took your pill and where you are in your pill packet. Please check the patient information leaflet for further information.
