Lestrin is an oral contraceptive, classified as a combined birth control pill due to the fact that it is based on two active ingredients, ethinylestradiol and norethisterone which are the synthetic bioequivalents to naturally-synthesised sex hormones oestrogen and progesterone respectively. Developed and marketed in the UK by Galen Pharmaceuticals pharmaceutical company, Loestrin is highly adept contraceptive pill available in two different strengths and able to prevent unwanted pregnancy in 99% of cases.

How reliable is Loestrin?
Loestrin is advertised as 99% efficient in preventing unwanted pregnancy, just like a majority of other birth control pills. However, as a combined contraceptive pill, Loestrin is somewhat more reliable than progesterone-only mini-pills. When used properly, it should, for all intends and purposes, completely eliminate risk of unwanted pregnancy, but 100% protection cannot be advertised due to risk of certain unforeseen circumstances or maybe unidentified conditions which can potentially impair the function of Loestrin pills.
However, there are also a number of identified medications and remedies which can adversely affect the efficiency of these birth control pills. So, in order to ensure maximum level of protection, you should pay special attention and if you have to take any of the following, be sure to use barrier contraception in case Loestrin efficiency has been compromised:
- Epilepsy medications
- HIV or AIDS treatments
- Antifungal medications
- St John’s wort
How do contraceptive pills work?
Hormonal birth control pills all rely on synthetic, man-made versions of naturally-occurring sex hormones, progesterone and oestrogen. The active ingredients of Loestrin, ethinylestradiol and norethisterone, will effectively mimic the natural hormones and via that mechanism of action, they will interfere with the natural processes related to menstrual cycle, but also to various preparations for pregnancy that female body goes through during every cycle, regardless of whether conception will actually take place. However, the aforementioned sex hormones play different roles in the female body and as such, the compounds mimicking them will act to decrease the chances of unwanted pregnancy in different ways.
Why is progesterone important for pregnancy?
Naturally occurring progesterone is absolutely crucial in timing and triggering ovulation, the process during which an egg cell is released by the ovaries to the fallopian tubes where it can get fertilised by sperm. If the conception takes place, the fertilised egg cell will travel to the womb and implant into the uterine wall where it will continue to develop. With this in mind, it comes as no surprise that synthetic progesterone acts by tricking the body into wrongly detecting that the ovulation had already taken place, thus preventing the ovaries from releasing egg cells.
The role of oestrogen in the menstrual cycle
On the other hand, synthetic oestrogen will provide additional protection in case the primary one, stemming from synthetic progesterone. It will contribute to the thickening of the cervical fluids and changes in the conditions alongside the uterine wall. These processes will help prevent unwanted pregnancy in different ways – the change in consistency of cervical fluids will make it harder for the sperm to reach the egg cell and the changes in the uterus will make it less likely for the fertilised egg cell to implant.
Can I buy Loestrin online in the UK?
Yes, it is possible to buy Loestrin online in the UK. While contraceptive pills might have been a bit of a taboo once, today they are a part of regular offer of numerous online clinics and pharmacies operating within the UK, so buying them online is easier and safer than ever before! However, you should keep in mind that just like all other contraceptive pills, Loestrin too is a prescription-only medicine and as such, it can be obtained only with a valid prescription issued by a certified medical professional.
