OC 21 TABLET
Product introduction
OC 21 TABLET is an effective contraceptive option used by women to avoid an unintended or unwanted pregnancy. It is usually used after unprotected sex or contraceptive failure (where the contraceptive method was broken/slipped/missed). It must not be used as a regular contraceptive method.
OC 21 TABLET comes as a single tablet or dose which can be taken with or without food. It must be taken as soon as possible within 72 hours (3 days) after the first episode of unprotected sex or contraceptive failure has occurred. It works primarily by preventing or delaying the release of an egg from the ovary (also known as ovulation), and therefore, the sooner it is used the better.
Overall, OC 21 TABLET is well tolerated. However, like all medicines, it can have some side effects too, but these generally do not last more than 1-2 days and not everyone using it may experience these. The most common side effects may include nausea, irregular bleeding before the next period, lower abdominal pain, tiredness, and headache. If you experience any side effect that persists or is worrying you, consult your doctor immediately.
Before taking OC 21 TABLET, check to ensure that you are not already pregnant, haven't missed your period or your period is not delayed by more than 7 days, or is not already more than 72 hours (3 days) since the first episode of unprotected sex or contraceptive failure. If any of the above mentioned is true, consult your doctor immediately.
Uses of OC 21 Tablet
Benefits of OC 21 Tablet
In Emergency contraception
OC 21 TABLET offers a safe and effective option for preventing unintended pregnancy. It is widely accessible and easy to use, making it a convenient choice for women seeking emergency contraception. Unlike some contraceptive methods, OC 21 TABLET can be taken at any time during the monthly cycle and does not require a physical examination or a prescription. It can also be used by women who cannot use oral contraceptive pills due to contraindications. OC 21 TABLET contains relatively fewer hormones compared to regular contraceptive pills, reducing the potential for metabolic effects over time. Additionally, its short exposure duration minimizes the risk of fetal malformations or congenital defects, and it does not increase the risk of ectopic pregnancy.

What is the difference between 'emergency contraceptive pill' and 'abortion pill'?
Pregnancy starts once the fertilized egg gets attached to the lining of the uterus (womb). Abortion pills contain medicine, which hinders the development of a pregnancy after it has occurred and also alters the character of the womb lining in a way that the fertilized egg gets detached, hence causing abortion. On the other hand, emergency contraceptive pills like OC 21 TABLET contain female hormones which delay the release of egg or prevent movement of sperm towards the egg. This prevents fertilization and hence pregnancy. OC 21 TABLET does not have any effect on a fertilized egg and hence does not cause abortion.
Is OC 21 TABLET effective if frequent acts of intercourse have occurred in a short duration of time?
Yes. It is effective if you have had several acts of intercourse in a short span of time. However, it is important that these acts have occurred within 72 hours before taking OC 21 TABLET. Also, since there is a chance of unintended pregnancy after frequent acts of unprotected sex in the same cycle, it is advisable to use a barrier contraceptive method (e.g. condom) until the next period even after using OC 21 TABLET.
