How Pregnancy Prevention Pills are Composed?

By | December 27, 2018

A large number of women in India use contraceptive pills as a measure to avoid pregnancies. These pills are also called ‘Birth Control Pills’. BCP or ‘Birth Control Pill’ has to be taken on a regular basis to interrupt the normal action of certain hormones in the body to prevent pregnancy. The pill contains mainly two man-made hormones, which naturally occur in female ovaries, to control the functioning of the ovaries. Unwanted 72 Composition is no different from the other contraceptive pills.
However, there is yet another type of ‘Emergency Contraceptive Pill (ECP)’ which is used by women to prevent unwanted pregnancy at times of emergency. The ECPs are not like birth control pills. They are not taken on a regular basis. These types of contraceptive pills are used particularly at the time of emergencies like the breakdown of condom, rape, slip off sex or even if two/three doses of BCPs are missed.
Composition and Working of Birth Control Pills
Birth control pills are especially designed to control the normal functioning of your menstrual cycle. These pills are composed by the combination of two major hormones – progestin and estrogen – which naturally occur in ovaries. These two hormones stop the ovaries to release an egg during the time of ovulation in a menstrual cycle to prevent pregnancy. These hormones also control the level of naturally occurring hormones in female ovaries. One of the hormones, progestin, in the contraceptive pill, makes the cervical mucus sticky and thick to prevent the entrance of sperms into the uterus.
The use of birth control pills may cause multiple side effects in the body. In some cases, these side effects could cause some severe damages. Some commonly known side effects of birth control pills are:
Change in the normal menstrual cycle
The complete absence of menstruation
Excessive bleeding
Nausea, breast tenderness or extreme mood swings
If you have a migraine, it could get worse due to the use of contraceptive pills.
Weight gain
BCPs may also cause some severe side effects:
Blood clotting
High blood pressure
Heart attack
However, many women prefer to take another type of BCP which does not contain estrogen. These types of BCPs are called ‘Mini-Pills’, which contain only one hormone, i.e. progestin. This type of BCP is mostly taken by those women who want to avoid the side effects of contraceptive pills, caused due to the presence of estrogen and women who are unable to take estrogen hormone due to some medical reasons. BCPs which do not contain estrogen are less likely to cause severe side effects in the body.
The dosage of Birth Control Pills
Most of the birth control pills come in either 21-day set or 28-day set. For the 21-day set of pills, women take one pill a day for 21days a month and then stop taking pills for the last seven days of the month. Whereas, women take one pill every day with a 28-day set of pills and therefore, there is no gap in between the months.
Since BCPs are mostly ‘combination pills’ they come in various numbers and package. There is another type of BCP which regulates the menstrual occurrence in the body of a woman. These pills come in a pack of 12-week hormone pills and 7-day inactive pills. This results in menstruation to occur once every three months.
On the other hand ‘mini pills,’ containing progesterone only, are taken on a regular basis. Women who take these pills may have irregular or no periods at all. This pill can be effective only if taken regularly on similar time without missing a single dose, whatsoever.
The composition of Emergency Contraceptive Pills
ECP or ‘Emergency Contraceptive Pills’ are a little different from birth control pills. They are not meant for regular use. They are only used for emergencies including break down of the condom, slip-off sex, rape, etc. to prevent any unwanted pregnancy. These emergency pills are also known as ‘the morning after pill’. The ECPs are mainly composed of a hormone called Levonorgestrel.
When to Take Emergency Contraceptive Pill?
The emergency pills are mostly over the counter medicines. Various brands are available in the market. Some of the most popular brands in India are ‘i-Pill’ and ‘Unwanted-72-Tablet’. These pills help in preventing unwanted pregnancies if taken within 24 to 72 hours of unprotected coitus. This is the last resort of stopping a pregnancy to occur. However, you should not consider it as a regular birth control method.
The effectiveness of Emergency Pregnancy Preventing Pills

However, if you are extremely overweight, the pill could be a little less effective. In that case, ask you gynecologist for a suitable solution. You may need some other form of emergency contraceptive.
Working on Pregnancy Preventing Pills
Emergency contraceptive pills such as ‘Unwanted-72-Tablet’ or ‘i-Pill’ contain levonorgestrel which prevents pregnancy with the help of three mechanisms, depending upon the time of menstrual cycle:
If the coitus happened around the time of ovulation, the pill prevents pregnancy by stopping the ovary to ovulate.
In case the time of ovulation is over, the pill prevents the fertilization from occurring
Finally, if the egg has already got fertilized, the pill stops it from getting implanted in the uterus.
However, one should not confuse such emergency pills like ‘Unwanted-72-Tablet’ with the medicines that prevent any sexually transmitted disease or the medication taken to induce abortion. These ECPs simply stops the pregnancy to occur in the female body only for about 96 to 98 percent of times.
The dosage of Emergency Contraceptive Tablet
