Unwanted 72 Tablet

Unwanted 72 is an emergency contraceptive pill that is to be taken to prevent an unplanned pregnancy after having unprotected sex. It is also known as morning-after pill.

What Is Unwanted 72?

It has a chemical composition of Levonorgestrel. It is to be taken as a single dose tablet with water after food. It is not necessary to take it in the morning or at any particular time of the day. But, it is considered to be most effective when taken within 24 hours of unprotected sexual intercourse. This is supposed to be sold under prescription but currently, it is available over-the-counter too and hence proper knowledge about the drug is necessary to prevent any unwanted side effects.

Unwanted 72 contains a hormone in high dose, inactivating LH (luteinizing hormone) and FSH (follicular stimulating hormone), and it ultimately makes the lining of the uterus unfavorable for implantation of fertilized egg and ovulation too. It thus works by stopping pregnancy after sex. It takes three days (72 hours) for pregnancy to occur after fertilization, which is what this pill stops from occurring. It does not terminate a pregnancy that has already occurred. So, it is important to take it in the stipulated time frame as directed by your doctor.

What precautions should you take while using unwanted 72 tablet?

As Unwanted 72 is a hormonal tablet meant for emergency purposes, they have to be used only in such one-off situations and not as a regular mode of contraception. Condoms or oral contraceptive pills (lower dose hormones) are more reliable forms of long-term birth control. An emergency pill can mess with your reproductive system if taken on a regular basis. It is advised not to take them more than twice in a span of six months. Also, it is important to take note that ECP does not offer protection from sexually transmitted infections, and only a condom (barrier method) can provide that.

Does Unwanted 72 Cause a Delay in Periods?

A change in the pattern of menstrual cycles for up to three cycles is a common occurrence after taking ECP. The period may come in early or be delayed from the expected date. The bleeding following a pill intake is known as withdrawal bleeding. Once the bleeding occurs, it is certain that pregnancy has been prevented. But, if there is a slight delay by up to seven days, it is advisable to test for pregnancy on or after the expected date of menses. If there is a considerable delay (more than seven days since the expected date of menses), it is necessary to consult a specialist to rule out pregnancy as well as other gynecological conditions by means of a pelvic ultrasound or transvaginal scan.

It is necessary to know the difference between withdrawal bleeding and implantation bleeding. Though both can look the same, there are some differences you can look for. Implantation bleeding will appear lighter in color, water-like consistency, more like spotting and no heavy bleeding or any clots can be associated with mild cramps and lasts for merely one to two days. It is always better to consult your gynecologist to get it confirmed.

Can you take Unwanted 72 after 72 hours?

Although rare, it is possible to still get pregnant after taking the pill. But, it is to be noted that no type of contraception is 100 % effective.

The effectiveness of Unwanted 72 goes down with time as follows:

  • 0 to 24 hours after the act - 90 to 95 % effective
  • 25 to 48 hours after the act - 85 % effective
  • 49 to 72 hours after the act- 58 % effective
  • After 72 hours - nearly nil
