Brevinor is a brand of contraceptive pill that contains two hormones, an oestrogen and a progestogen. Because it contains both types, it’s considered to be a combined hormonal contraceptive pill.

Combined pills are one of the most reliable forms of reversible contraception, and they can be stopped whenever you want or need to, without having to reduce your dosage or wean off the medication.

Brevinor is a monophasic pill, which means that each pill in the pack contains the exact same dosage of hormones, compared to other pills such as Triregol, where the dosages vary throughout the month.



Brevinor pill

The Brevinor pill is a popular method of combined hormonal contraceptive pill, and is used mainly to prevent an unwanted pregnancy in sexually active women. However, because of how the contraceptive pill works, doctors may also choose to prescribe it to regulate menstrual cycles in females that experience heavy or painful periods.

The Brevinor pill works in three ways to prevent the fertilisation of an egg.

Firstly, it thickens the mucus within the cervix, making it incredibly impermeable to sperm. Secondly, it prevents your ovaries from releasing an egg, and thirdly, it thins the lining of the womb to make sure that it would be inhospitable to any egg.

The triple-action defence means that Brevinor is 99% effective at preventing unwanted pregnancies, and can be even more effective if used in conjunction with another method of contraception, such as condoms.

Brevinor ingredients

The active ingredients in Brevinor include the oestrogen, ethinylestradiol, and the progestogen, norethsiterone.

Norethisterone is an older form of progesterone compared to more recently developed forms such as desogestrel, but it is still effective stopping an egg from being fertilised, especially when used alongside an oestrogen. Other contraceptive pills that contain both norethisterone and ethinylestradiol include:

  • Synphase
  • Norimin

Whilst it contains the same ingredients as Brevinor, Synphase is a triphasic pill, meaning that it contains three different amounts of hormones, signified by different coloured pills. Norimin is monophasic, like Brevinor.

Brevinor side effects

Brevinor, like all other methods of hormonal contraception, can cause unwanted side effects due to the hormones in the tablets and how they work within the body. Whilst most women that take Brevinor find the side effects mild or bearable, some find that they have to switch to a different pill with an alternative type of oestrogen or progestogen in order to minimise the adverse effects.

Some of the most commonly reported Brevinor side effects include:

  • Nausea
  • Upset stomach
  • Weight gain
  • Appetite changes
  • Headache
  • High blood pressure
  • Depression
  • Swollen and sore breasts
  • Change in libido
  • Worsened womb disorders
  • Irregular vaginal bleeding
  • Changes in how the body breaks down sugars, fats or vitamins

In addition to these side effects, hormonal contraceptive pills like Brevinor can also increase your risk of experiencing a blood clot. This risk is thought to be highest during your first year of taking any kind of hormonal contraceptive, and also if you’re starting the pill again after a break of 4 or more weeks. After 12 months, the risk of blood clot is reduced, but will always remain higher than those that don’t take hormonal contraception whilst you stay on the pill.

Because of the increased risk of blood clots whilst taking Brevinor, it’s important to stay aware of the red flag symptoms so that you can spot any blood clots early. Some of the hallmark symptoms of a blood clot somewhere in your body include:

  • Coughing up blood
  • Swollen or tender stomach
  • Sudden sharp pain in the chest
  • Sudden breathlessness or painful breathing
  • Pain or inflammation in the veins in your legs
  • New onset of migraine
  • Worsened migraines
  • Sudden and unusual or severe headaches
  • Dizziness or fainting
  • Problems with your sight or speech

If you experience any of these symptoms whilst taking Brevinor, you should call 999 immediately and state your symptoms and the medication that you’re taking. Even if you don’t think that your symptoms are serious, blood clots can progress quickly and can be extremely serious. Always seek immediate medical help if you suspect that you have developed a blood clot.

You may be more at risk of experiencing side effects of Brevinor if you have been diagnosed with certain medical conditions. This is because of the elevated levels of oestrogen and progesterone throughout the month, which can cause problems in some females. If you have any of the following conditions, you should speak to your doctor before you buy Brevinor, as it may not be safe or suitable for you:

Allergy to any Brevinor ingredients
Personal/family history of blood clots
Previous heart attack or stroke
High levels of fat in your blood
History of cervical cancer
History of womb cancer
History of breast cancer
History of vaginal cancer
History or pruritis or jaundice in pregnancy
History of pemphigoid gestationis in pregnancy
Severe chronic liver disease
Unexplained vaginal bleeding
Hepatitis C
Visual disturbances
Cardiovascular disease
High blood pressure
Kidney disease
Multiple sclerosis
Any breast problems
Varicose veins
Liver dysfunction
Severe deperession
Uterine fibroids
Irregular periods
Sharp pain in the abdomen
Sickle cell anaemia
Any condition likely to worsen in pregnancy

These conditions may put you at increased risk of side effects and complications of hormonal birth control, including some hormone sensitive cancers such as breast cancer, womb cancer, cervical cancer or vaginal cancer.

To read more about the slightly increased risks of some cancers, please read the patient information leaflet thoroughly before you take any of the Brevinor pills. In addition to this, you can speak to your own doctor or local pharmacists about hormonal contraception and the associated risks.

Brevinor acne

Whilst no contraceptive pill is guaranteed to improve acne, sometimes, doctors can prescribe it to females that suffer with the condition. This is because some forms of hormonal contraception have been shown to improve symptoms of acne as a secondary effect. Some of the contraceptive pills that females with acne are sometimes offered include:

  • Brevinor
  • Yasmin
  • Zoely
  • Microgynon

Sometimes, Dianette (co-cyprindiol) is also prescribed to women that suffer with acne. Dianette first started as a contraceptive pill, but due to associated risks, is no longer prescribed for that reason unless otherwise stated by your own GP.

If you have acne and think that Brevinor might be able to help you, you should speak to your own doctor about the pros and cons of taking hormonal contraception for acne. Please note that Alpha Medicines can only prescribe Brevinor for contraceptive purposes.

How to take Brevinor

For Brevinor to work most effectively, you should take one tablet every day at the same time each day. This is to help you get into a routine, as a missed pill can put you at risk of pregnancy.

Brevinor comes in strips that contain 21 pills. Ideally, you should take your first pill on the day that you start your period so that it can protect you from the first dose. However, you can also start the pill on any day up to day 5 of your period, as long as you use other methods of contraception or abstain from sex for 7 days, as you won’t be protected by Brevinor up until this point.

If you have irregular periods, and aren’t sure if you’ll be able to take your first pill within days 1-5 of your period, you should make an appointment with your GP to ask their advice on when you should start using Brevinor.

When you have finished a blister strip, you should have a 7 day break from taking Brevinor. During this time, you may have a withdrawal bleed, and providing that you’ve taken your tablets correctly, you should start your next blister pack on the same day of the week that you started your last one. It might help you to write down in a diary or calendar when you’re due to finish your 7-day break.

Brevinor missed pill

If you forget a pill, you might not be protected against an unwanted pregnancy. However, if it’s been less than 12 hours since you were supposed to take your last pill, you can take it as soon as you remember and still be protected.

If it’s been over 12 hours since your last dose was due, you should still take the missed pill, even if it means taking two pills in one day. However, this means that you may not be protected, and should use additional contraceptive methods for the next 7 days to make sure that you don’t become pregnant.

If you have fewer than 7 pills left in your blister pack after your missed pill, you should start the next strip of pills as soon as you finish the current one, with no 7 day break. If you don’t have a withdrawal bleed after the second blister pack, you should contact your doctor or take a pregnancy test.

If you have more than 7 pills left in your blister pack after your forgotten or missed pill, you can take your 7 day break as normal.

If at any point whilst taking Brevinor you become concerned that you may be pregnant, you should make an appointment with your GP.
