Yasmin is a combined monophasic birth control pill that is developed and marketed in the UK by Bayer pharmaceutical company. As a hormonal treatment, Yasmin contains synthetic hormones called ethinylestradiol and drospiernone which act as bioequivalents to oestrogen and progesterone respectively. Aside from being highly adept at preventing pregnancy, Yasmin is also commonly prescribed for treating heavy and painful menstrual bleeding.

How reliable is Yasmin?

  • 99% efficient in preventing pregnancy
  • Provides additional layer of protection thanks to ethinylestradiol
  • Prevents ovulation
  • Makes it difficult for sperm to reach the egg cell
  • Efficiency can be compromised by certain drug interactions

Yasmin is a relatively safe and reliable birth control treatment which is advertised as 99% efficient in preventing unwanted pregnancy if used properly. As a combined oral contraceptive, Yasmin is more effective as compared to progesterone-only mini-pills alternative due to an additional layer of protection provided.

However, in order to make the most out of taking Yasmin birth control pills, you will have to make sure that you are using them properly – meaning, you will have to take the pills daily, without missing a dose and while carefully following the guidelines provided in the official patient information leaflet that is issued within every pack of Yasmin.

What can impair efficiency of Yasmin?

There are certain medications and remedies which have been known to be able to compromise the efficiency of birth control pills, making the use of barrier contraceptives necessary during the periods of reduced protection. To learn more about which medications you should avoid and for how long the efficiency of Yasmin might be compromised if you will have to use them, please consult the official patient information leaflet.

Some of the medications known to cause problems with Yasmin protection levels include:

  • Antiepileptics
  • Tuberculosis medications
  • HIV or AIDS medications
  • Antibiotics
  • St John’s wort
  • Cyclosporine

How does Yasmin prevent pregnancy?

  • Mimicking the activity of naturally occurring sex hormones
  • Preventing ovulation from taking place
  • Increasing thickness of the vaginal fluids
  • Changing environment along the uterine wall
  • Multi-layered protection

Yasmin is a combined birth control pill, meaning that it contains two active ingredients, synthetic hormones ethinylestradiol and drospirenone which act by mimicking the activity of oestrogen and progesterone, respectively. Both of these naturally occurring sex hormones play important roles in the changes the female body undergoes every month in order to prepare itself for possible pregnancy. So, it comes as no surprise that efficiency of Yasmin is rooted in the interference in these processes.

How Yasmin prevents ovulation?

Progesterone is a very important sex hormone as it plays a crucial role in triggering ovulation, the release of the egg cell from the ovary to the fallopian tube. By introducing synthetic progesterone (progesterone bioequivalent, drospirenone in case of Yasmin), it is possible to trick the body into “thinking” that the ovulation already took place, so the egg cell won’t be released, making it impossible for the woman to conceive that month.

What is the role of oestrogen in oral contraceptives?

As exemplified by progesterone-only mini-pills, synthetic oestrogen (ethinylestradiol in case of Yasmin and most other birth control pills available in the UK) is not necessary for successful contraception. So, what is its role?

The role of synthetic oestrogen in Yasmin is twofold – on one hand, it contributes to the prevention of hormonal imbalance and thus, it helps reduce the risk of experiencing side effects directly linked to hormonal imbalance. On the other hand, the presence of synthetic oestrogen will provide an additional second layer of protection. This multidimensional approach is not unique to Yasmin, but is the characteristic of all combined birth control pills, including somewhat lesser known Zoely.

  • Synthetic progesterone prevents ovulation
  • Synthetic oestrogen:
    • Makes it harder for sperm to reach the egg cell
    • Makes it harder for egg cell to implant into the womb

More specifically, the synthetic hormone will contribute to the thickening of the vaginal fluids, making it harder for sperm to navigate through the cervix. At the same time, the presence of this compound will change the environment along the uterine wall, making it harder for fertilised egg cell to successfully implant. While prevention of ovulation due to synthetic progesterone will be enough to reduce the risk of unwanted pregnancy, synthetic oestrogen will serve as a back-up protection.

Can I buy Yasmin online in the UK?

Yes, it is possible to buy Yasmine contraceptive pills online in the UK, but you can do so only with a valid prescription issued by a certified medical professional as birth control pills are prescription-only medications in the United Kingdom. Luckily, if you are looking to buy Yasmin without leaving the comfort of your own home and just by relying on internet, the good news is that this is perfectly doable.

  • Contact online clinic of your choice
  • Consult with doctor about your suitability for using Yasmin
  • Obtain a prescription
  • Buy Yasmin online (through the online clinic)
  • Wait for delivery to the address you provided

The prescription for this type of medications can be obtained without face-to-face consultations with a doctor, but you will still be required to fill in a detailed medical questionnaire that the doctor will use to assess your suitability for using Yasmin.

If everything is in order, the prescription will be issued and used to have the medication sent from the partner pharmacy to the address you provided. Alternatively, the doctor might recommend an alternative oral contraceptive.

How to take Yasmin pills?

In order to ensure maximum levels of protection, you have to take Yasmin exactly as instructed by your prescriber and in line with the guidelines provided in the official patient information that is issued within every pack of the medicine. The most important things you should keep in mind are the necessity to take Yasmin pills in order, without skipping or missing a dose and the pattern of taking one pill each day at the same time for 21 days followed by one week without any pills.

How to take Yasmin for the first time?

If you are about to start taking Yasmin for the first time, or if you are switching from a different birth control pill, you will have to carefully read through the information leaflet in order to learn how exactly should you make the transition or commence Yasmin treatment for the first time.
