Sunya is a combined birth control pill commonly prescribed to women in the UK for preventing pregnancy, but also for providing relief from symptoms of exceptionally heavy and painful periods. Classified as a hormonal oral contraceptive, Sunya contains two synthetic hormones, ethinylestradiol and gestodene which mimic the functions of oestrogen and progesterone respectively in order to influence the natural processes female body undergoes through every month in order to prepare itself for potential pregnancy. Sunya is sometimes colloquially classified as 21-day pill because it is taken for the first three weeks of the menstrual cycle, followed by one week when no pills are taken.

How reliable is Sunya?

Just like many other birth control pills, Sunya is advertised as 99% reliable meaning that it should technically provide complete protection from pregnancy provided that it is taken properly. And this is not something that is hard to achieve, you simply need to take the pills in the correct order, don’t forget to take them and stick to the instructions provided by your prescriber and in the official patient information leaflet that is issued within every pack of Sunya.

However, there is yet another thing that you should keep in mind. There are several medications, remedies and even foodstuffs that might compromise the efficiency of Sunya, so you should be careful when using those. If you cannot avoid taking some of the medications in questions, than you will have to use additional barrier protection during the period Sunya efficiency is impaired. For more details on how long that might be, please refer to the patient information leaflet.

How Sunya prevents pregnancy?

Sunya is a hormonal birth control pill, just like the vast majority of the products of the same class on the UK markets. That means that Sunya contains synthetic, manmade hormones which are capable of mimicking naturally-occurring sex hormones once they are introduced into the body. Combined contraceptive pills contain two active ingredients of the type. In case of Sunya, they are ethinylestradiol and gestodene which are synthetic bioequivalents of oestrogen and progesterone, respectively.

Both sex hormones play an important role in preparing the female body for pregnancy during each menstrual cycle. The mechanism of action of birth control pills is directly tied to this fact. When we approach the question in more detail, we can say that progesterone plays a crucial role in these processes by timing ovulation, the release of the egg cell from the ovaries to the fallopian tubes, where it can get fertilised.

Synthetic hormones and prevention of conception

If the fertilisation occurs, the egg will travel to the womb and implant into the uterine wall where the foetus can continue to develop. The environment in the uterus is in turn directly tied to the activity of oestrogen. With this in mind, the mechanism of action of Sunya seems almost straightforward. Thanks to synthetic progesterone, gestodene, this contraceptive pill will trick the body into “thinking” that ovulation already took place, so the egg cell will not be released.

But, combined birth control pills have an additional secondary line of defence. Through ethinylestradiol, synthetic oestrogen, Sunya will change the environment by the uterine wall, making it much harder for the egg cell to implant. At the same time, it will contribute to the thickening of the vaginal fluid which will in turn make it more difficult for sperm to navigate through the cervix and reach the fallopian tubes. As a consequence, combined oral contraceptives such as Sunya will prevent pregnancy in several different ways and this multidimensional approach makes them more reliable that progesterone-only alternative in the form of mini-pills.

Can I buy Sunya online in the UK?

Buying contraceptive pills online is perfectly doable in the UK. A number of online clinics operating within the country will offer you to get your birth control pills without ever leaving the comfort of your own home. And even more than that – today you can consult with a doctor and ask for advice about what contraceptive pills are the best for you just by using your computer or smartphone.

But, you should still keep in mind that contraceptives such as Sunya can be legally obtained only with a valid prescription issued by a certified medical professional. So, prior to buying Sunya online, you will first have to consult with a doctor. This can be done fairly easily – most online clinics will present you a specialised medical questionnaire that you will be required to fill in. This information will be used by the doctor employed at the online clinic to gain a better understanding of your medical profile and history. With this knowledge, it will be possible to make an informed decision regarding your suitability for taking Sunya. If everything is in order, the prescription will be issued and used that same moment to have the medicine delivered from a partner pharmacy to the address you provided. If not, an alternativ such as Synphase might be recommended.

How to take Sunya birth control pills?

As was mentioned, in order to ensure maximum level of protection against unwanted pregnancy, you should always use Sunya exactly as instructed by your prescriber. The detailed guidelines and additional information on the topic can also be found in the official patient information leaflet that you will find within your pack of Sunya.
