Brevinor Contraceptive Pill

Many women experience no side effects with the Brevinor pill. However, some women might notice headaches, nausea, mood changes, or breast discomfort. In rare cases, blood clots can develop. It's worth noting that Brevinor carries a slightly higher risk of blood clots compared to some other pills. If you have any concerns, just send us a message through your account.

It’s perhaps reassuring to know that when it comes to the Brevinor pill and weight gain, there’s typically no direct link between most forms of birth control and gaining weight.

When used correctly, the Brevinor birth control pill provides you with 99% protection against pregnancy. However, if pills are occasionally missed or taken irregularly, the effectiveness drops, and about 9 in 100 women are likely to get pregnant. Follow the advice outlined in the section ‘If you miss your pill’ to ensure you stay protected.

Stomach issues can impact your protection. For example, vomiting or severe diarrhoea can affect how well the Brevinor combined pill works. That’s because the medication may not have been fully absorbed into your bloodstream. In these situations, keep taking your daily pill, but use condoms during sex until you're well again. 

If severe diarrhoea continues beyond 24 hours or vomiting occurs within 3 hours of you taking Brevinor, follow the missed pill guidelines to ensure you stay protected.

It’s important that you should only begin taking Brevinor when you're confident you aren't pregnant.

Brevinor, like other combined oral contraceptives, may help with acne in some women due to its hormonal effects. However, results can vary significantly from one person to the next. So it’s best to ask your GP or other healthcare professional about using a contraceptive pill to treat acne.

As long as you do not have a short or irregular menstrual cycle, starting Brevinor on days 1-5 of your period typically provides immediate protection from pregnancy.

If you start after day 1 and have a short or irregular cycle, you will need to use condoms for 7 days if you have sex. Your clinician can advise if you need additional contraception during those 7 days.

Brevinor contains two hormones (ethinylestradiol and norethisterone) that work together to prevent pregnancy. These hormones stop your ovaries from releasing an egg and make it harder for sperm to reach an egg. They also prevent a fertilised egg from implanting in the womb lining.
