First emergency contraception

It is first time you had unplanned unprotected sex and you are panicking – what if you would get pregnant? what can be done? is there any solution or prevention?

The answer is – YES – during following 72 hours you can use so called “emergency contraception” and prevent unplanned unwanted pregnancy.

It is so rare to find your true LOVE. And sometimes you need full relaxation and just happiness and love. If you are lucky you can have a very special day full of love, flowers, romantic dinner and paradise night.
What if you had unexpected romantic day and you absolutely forgot that you are on ovulation period and you did not protect yourself from pregnancy?

Don’t worry! There are easy solutions called “Plan B” or “emergency contraception” or “morning after pills”.

Plan B is a kind of contraception which used as an emergency procedure to prevent unwanted pregnancy which could happen after unprotected sexual intercourse. Plan B can be used in following cases:

  • when no contraceptive has been used,
  • when contraceptive methods failed (missed pills, condom rupture, diaphragm dislodgement, etc.),
  • when girl or woman has been a victim of the sexual attack (abuse).

There are two kinds of Plan B and/or emergency contraception:

1. emergency contraceptive pills (progestogen-only or combined oestrogen-progestogen oral contraceptives);

2. copper-releasing intrauterine devices (IUDs).

Plan B should be used within 3 days (72 hours) after unprotected sexual contact.

Combined pills (oestrogen-progestogen pills) for Emergency Contraception (Plan B)

Two pills should be taken as the first dose as soon as possible after unprotected sexual contact but no later than 72 hours. It should be followed by another two pills after 12 hours.
Four pills can be taken as the first dose as soon as possible (same as above). It should be followed by another four pills after 12 hours.

Progestogen-only pills for Emergency Contraception (Plan B)

A single dose of 1.5 mg levonorgestrel should be taken as soon as possible after unprotected sexual contact but no later than 72 hours.
One dose of 0.75 mg can be taken as the first dose as soon as possible (same as above). It should be followed by the same dose after 12 hours.

Plan B with combined pills reduce the risk of pregnancy after unprotected sexual contact by about 56%-89% if taken within 72 hours. Plan B with progestogen-only pills reduce the risk by about 60%-93% if taken within 72 hours.

In general the probability of the pregnancy after one unprotected sexual contact is 8%. Women who use Plan B (emergency contraception) are able to reduce the pregnancy risk to 1%-2%. The efficacy is better the sooner Plan B (emergency contraception) is used after unprotected sex.

In general Plan B with emergency contraception pills are 95% effective if taken within 24 hours; 85% effective if taken within 25-48 hours and 58% effective if taken within 49-72 hours.

Emergency Contraception with hormonal pills – Mode of action

Hormonal emergency contraception achieves its contraceptive effect by several mechanisms depending on the time in a woman’s cycle it is taken. It can inhibit or delay ovulation and may also interact with ovum and sperm transport, and fertilization. Studies differ on whether hormonal emergency contraception can cause changes in the endometrium that would be sufficient to interfere with implantation. There is no evidence that hormonal emergency contraception dislodges the embryo after implantation has occurred.

Emergency Contraception with cooper-releasing IUD

A cooper-releasing IUD can be inserted by the professionals within 5 days of unprotected sexual contact which will insure your Emergency Contraception (Plan B).

Emergency Contraception with IUDs is highly effective (up to 98% of cases) with the possibility of the pregnancy less than 1%.

When IUD is used for Emergency Contraception?

  • When the Plan B with hormonal methods are less effective (because more than 72 hours have elapsed).
  • The client is considering using an IUD for continuous, long-term contraception (not only for Plan B).
