Brevinor is a combined oral contraceptive pill developed and marketed by Pfizer pharmaceutical company within the UK. As all other birth control pills, Brevinor also works by mimicking the functions of oestrogen and progesterone, thus interfering with the menstrual cycle, preventing ovulation and subsequently preventing pregnancy. As a branded medication which showed very promising results in numerous trials and tests, Brevinor is rated very highly both by professional medical experts prescribing it and countless women in the UK who are actually using it.

How does Brevinor work?

Each month, the female body will undergo various processes and changes as a part of the natural monthly cycle. One of the most important processes which is directly tied to pregnancy is ovulation, the release of the egg cell from the ovary to the fallopian tube where it can get fertilised by sperm. Alternatively, if the fertilisation doesn’t take place, the egg will break down in the uterus from where it will be discharged along with the endometrium through menstrual bleeding.

All of these processes are guided and influenced by the activity and the balance of sex hormones, namely oestrogen and progesterone. By extension, it comes as no surprise that any interference with these naturally-occurring compounds can have significant consequences on the fertility. This is the main premise behind every combined birth control pill. Same is true for Brevinor.

In simplest term, the active ingredients of this contraceptive pill will simulate the activity and the function of the sex hormones, thus tricking the body into “thinking” the ovulation does not need to occur at all. As a consequence, the egg cell won’t be released from the ovary and the uterine wall lining will not get thick enough to be able to sustain egg implementation even if it were to occur. At the same time, by changing the hormonal balance in the body, Brevinor will contribute to the thickening of the vaginal fluid, making it much more difficult for sperm to travel through the cervix and reach the egg.

Can I buy Brevinor online in the UK?

Yes, it is possible to buy Brevinor online in the UK. However, regardless of whether you are looking to buy birth control pills online or via the traditional route, contraceptive pills are prescription only medications and as such, they can be obtain only with a valid prescription issued by a certified medical professional. And this is not without good reason. The efficiency of birth control pills when it comes to preventing unwanted pregnancy is just one part of the issue. Even more importantly, the choice of suitable birth control pill will also minimise the risk of side effects and make the whole treatment less invasive and disruptive when it comes to natural hormonal cycles.

In order to make sure that Brevinor is the right choice for you, the doctor employed at the online clinic of your choice will ask you to fill in a customised and detailed medical questionnaire that can then be used to assess your suitability for this medication. If everything checks out, the doctor will issue a prescription and have Brevinor delivered from the partner pharmacy to the address you provided. Alternatively, you might be prescribed a different combined contraceptive such as Cilest, for example.

How is Brevinor used?

When using contraceptive pills, it is of uttermost importance to follow the instructions provided by your prescriber exactly. This is the only way to ensure maximum possible protection against unwanted pregnancy and the optimal efficiency of Brevinor. At the same time, this will also help you minimise the risk of experiencing side effects.

What are Brevinor side effects?

Learning about the side effect prior to commencing treatment is highly recommended for all prescription medications. The same is true for birth control pills such as Brevinor. However, since contraceptive pills directly interfere with the hormonal balance, the side effects can be somewhat different than expected. In addition to this, learning about the side effects will allow you to easily differentiate between uncomfortable, yet benign side effects and those which might require you to quit taking Brevinor and seek immediate medical advice.

Aside from the risk of an allergic reaction which is a risk that comes with any medication, dangerous possible side effects of Brevinor mostly revolve around increased risk of developing a blood clot. The symptoms that might be indicative of this include:

  • Swelling or tenderness in the abdomen
  • Coughing up blood
  • Sharp and severe pain in the chest
  • Sudden shortness of breath or painful breathing
  • Inflammation of the veins in the legs
  • Migraines (without prior history)
