Emergency Contraception

Yuzpe Method Emergency Contraception

At A Glance:

  • Contraceptive pills can be used as emergency contraception after unprotected sex to decrease the chances of pregnancy.
  • Should only be used after unprotected sex, if another contraceptive method failed, or if no contraception was used.
  • Pills can be up to 88% effective if taken within 72 hours (three days) after unprotected sex. The sooner, the better.
  • The Yuzpe Method is not guaranteed as effective as the daily intake of pills as a regular contraceptive method.

What Is It

Emergency contraception lessens the chances of a woman getting pregnant if taken within the first few days after unprotected sex. It should be taken as a last resort when other contraceptive methods failed or were not used during unplanned sex.

You may want to use it if:

  • No contraceptive was used
  • A contraceptive was used incorrectly
  • A contraceptive was used correctly but was immediately observed to have failed
  • The condom broke, slipped, or was used incorrectly
  • Three or more combined oral contraceptive pills were consecutively missed
  • More than three hours have passed since the usual time of intake of the progestin-only pill
  • You are more than four weeks late for the depo injectable shot
  • Withdrawal failed and ejaculation occured in the vagina or on external genitalia

Emergency contraceptive pills are also called “morning after pills,” which gives the wrong impression that they should be taken the morning after unprotected sex, when in fact, they can already be taken as soon as possible without having to wait for the morning after.

The Yuzpe Method

In the Philippines, the daily oral contraceptive pills available can be used as emergency contraception through a specific method. The Yuzpe Method prevents pregnancy before it happens; it’s a backup plan, and should not be done regularly. If you are interested in taking oral contraceptive pills as a regular method of contraception, consult your healthcare provider to know more. It is also strongly advised to consult a healthcare provider when using the Yuzpe Method.

How It Works

Pregnancy doesn’t happen immediately after sex, which is why preventing it after unprotected sex is still possible. Take note: it can take up to seven days for the sperm cell and egg cell to meet after sex.

Pills prevent the sperm cell and egg cell from meeting and result in pregnancy by releasing a large dosage of the hormones estrogen and progestin in the body. Through this, the egg cell is stopped or delayed from leaving the ovary and traveling to the uterus for fertilization.

The Yuzpe Method lessens the chances of pregnancy to happen if taken within the first few days after unprotected sex; however, how much the chances are reduced depends on how soon the pills are taken after the incident, and at what stage the woman’s menstrual cycle is already when she takes it. The chances of getting pregnant are higher when the woman had unprotected sex during the 2nd or 3rd week of her menstrual cycle; this makes the effectiveness rate not absolute. It’s always better to use a regular form of contraception, such as a condom or the daily oral contraceptive pills.

How To Use It

Do the Yuzpe Method as soon as possible after unprotected sex. Although it can reduce the risk of pregnancy if used within 72 hours after the incident, taking it sooner makes it more effective.

Take four (4) Ethinyl Estradiol 30mcg/Levonorgestrel 150mcg, Ethinyl Estradiol 30mcg/Levonorgestrel 125mcg, or Ethinyl Estradiol 30mcg/Norgestrel 300mcg pills as soon as possible. Follow this with another dose of four (4) pills 12 hours later. You should be able to take a total of eight (8) pills.

If vomiting occurs within 2 hours after taking either of the doses, you need to repeat that dose. Remember, the sooner the pills are taken, the better.

It’s normal for your next period to be different from normal after taking emergency contraception.

  • It may come earlier or later than usual
  • It may be heavier, lighter, more spotty, the same as usual

You may also feel dizzy and nauseous after taking the pills.

The Positives

  • Pregnancy can be prevented after unprotected, unplanned or unsolicited sex.
  • Offers more protection and peace of mind than doing nothing.
  • Easy to use.

The Negatives

  • Can cause nausea, fatigue, an upset stomach and vomiting
  • Can cause breast tenderness, irregular bleeding, dizziness, headaches (short-term), and temporary changes to the menstrual cycle
  • The chance of preventing pregnancy is higher the closer the Yuzpe Method is used in the time after unprotected sex. Generally, within 72 hours after is the effective period. Beyond that, it cannot guarantee effective protection.

  1. Hello! I had my last period on April 4-10, and had unprotected sex on the 14th, and used withdrawal method. I did the yuzpe method with trust pills for the first time on the 17th, just a few hours short of the 72 hour window. I’m expecting my period to come soon, but haven’t had the chance to take a PT yet (still too nervous). Is there a possibility my period will be delayed?

    1. Hi, Toni! As mentioned in this article, the Yuzpe Method may cause temporary changes to your menstrual cycle such as delayed menstruation.

    1. Hi, Sach! You may do it as often as needed, but it may worsen side effects, and using regular contraception offers more effective protection against unintended pregnancy.

  2. I took 4 trust pills yesterday and now 4 pills (12 hours interval) as Yuzpe method. May I know if okay lang by tomorrow mag-start ako mag-take ako ng other combined pills like Yaz pills?

  3. Nag take po yung girlfriend ko ng pills 22hr after namin mag intercourse and nagawa naman po niya ng tama yung pag take ng pills is it safe na po ba kasi nabasa ko po na the sooner mas effective ito and lagi po kasi siya napaparanoid about sa pamahiin like sa pusa na nag iingay ganon ask ko lang po if wala kaming mabubuo o safe na siya dahil nakapag take siya agad

  4. Hi, Ask q lng nag take aq ng 4 pcs ng trust around 2pm then nalate aq itake yung another 4pcs nainom q ito after 17 hours instead na after 12 hours. Ok lng pon b yun o need q ulitin ang buong process at magtake uli ng panibago

  5. Just want to know what should i do with the remaining pills? should i continue drinking it until i finish the whole set?

    1. Hi, CC! You may take the remaining pills as your regular form of contraception. If you’d like to, take 1 pill every day at around the same time (ex. every 8PM). If not, you don’t have to consume the remaining pills.

  6. Just to give everyone a success story: this is effective for me! I used Yuzpe method (Trust Pill) immediately (as in one hour after the accident) and during that time, it’s the third day since my last period. No nausea, no headaches, I just felt a rise in my temperature and breast tenderness. After 8 days, I had a mild bleeding for 3 days. I’m 11 days delayed but I already got my period afterwards. I had very painful but tolerable cramps. Days before my period I had PT. It’s nerve-wracking waiting for the lines in pregnancy test to appear. Luckily, it came out negative.

    Also sharing another fact: Yuzpe method tends to be much more effective when taken before ovulation and taken a few days before your period. The farther from fertility window, the better. Please take it as soon as the unprotected sex happens! The earlier the better!
