Abstract

There is an enormous shift in attitude among the youth towards sex. Although they are leading a modern lifestyle, they are often caught up in unfamiliar situations. This article aims to create more awareness regarding the popular 'morning-after' pill and how to use it correctly to avoid an unplanned pregnancy.

I-Pill - When to Take and Its Side Effects

Accidents do happen. That is the reason we have emergency contraceptive pills such as I-pill available. However, these are not regular birth control pills. They are meant to be used only in emergency situations.

They are never to be used as the primary method of contraception. Also, this tablet is recommended for use by women aged 25 to 45. It is important to note that it is not intended to be used by teenagers whose reproductive organs are still maturing.

Who Needs I-Pill

I-pill is the quick solution, if you are worried about an unplanned pregnancy after:

  • an act of unprotected intercourse.
  • failure of the condom.
  • missing regular birth control pills.
  • forced sex or sexual assault.

How Does I-Pill Work

Depending on where you are in your cycle, the I-pill works in two ways to prevent pregnancy.

  • It prevents the ovaries from releasing the egg.
  • If the egg has already been released, it prevents the egg from getting fertilized or implanting.

How and When to Use I-Pill

Although it is referred to as the 'morning-after pill', it can be taken even right away. It is most effective when taken immediately after the act for up to 24 hours after (90 to 95 %). The effectiveness comes down to 85 % when taken from 25 to 48 hours after and to 58 % when taken between 49 to 72 hours after. If it is taken after 72 hours, it may not work at all.

It comes as a single tablet which is to be taken with water after food to prevent vomiting. If you vomit within three hours after taking the I-pill, it is recommended to take another I-pill as quickly as possible.

What Are the Side Effects

Short-term side effects include:

  • Spotting or bleeding.
  • Nausea.
  • Breast tenderness.
  • Headache.
  • Lower abdomen pain
  • Weight gain.
  • Altered periods (late, early or absent).
  • Hormonal imbalance.
  • Mood swings.
  • Rarely an allergy, causing skin rashes.

Repeated careless usage can affect your periods permanently.

What Happens When I Take I-Pill Without Sperms Entering

If you had an unprotected exposure, but are not sure of your risk of getting pregnant, it is still recommended to take an I-pill as there are no special side effects if taken when you were not exposed to sperms.

When Should I Use Regular Birth Control Again

If you took an I-pill because you missed taking your regular oral contraceptive pills for three days in a row, you could start using your regular pills from the next day onwards.

Reason for Bleeding After Intake of I-Pill

Many women have intermenstrual spotting or bleeding commonly known as 'withdrawal bleeding' five to seven days after taking I-pill. But, if you do not get your periods within three weeks, it is advised to take a pregnancy test.

Will I-Pill Cause Infertility

While the I-pill is not proved to affect fertility and future pregnancies directly, they are hormonal pills that are meant to disrupt the natural cycle of the body. So, when it is taken more than twice in a span of six months, it can throw the menstrual cycle off balance and make ovulation unpredictable. Your periods can become irregular, and the flow can become heavier or lighter.

Does I-Pill Cause Abortion

I-pill prevents pregnancy from happening in the first place. It is to be used only before a pregnancy is established. It does not cause abortion in an already pregnant woman. It has no effect on pregnancy.

If you miss your period even after taking I-pill, it is possible that the pill did not work for you. In that case, consult your doctor for the next course of action.

Is Pregnancy Still Possible After Taking I-Pill

I-pill has a good success rate when taken within the stipulated time. Still, like with any other type of contraception, there is a slight chance of failure with the I-pill too. So, it is still necessary to consult a doctor for a follow up three weeks after taking I-pill to rule out a pregnancy, both uterine and in the tube.
