Emergency Contraceptive Pill
What it is . . .
Emergency Contraceptive Pills (ECP) are a high dose birth control pill given by prescription or through a pharmacist. The most commonly used pill brand is Ovral, however there is also Plan B. It will be prescribed in two doses of two pills each (total 4 pills). The first dose must be taken within 72 hours of unprotected sexual intercourse. The second dose is taken 12 hours after the first dose. The sooner after unprotected sex ECP is taken, the more effective it is.
How it works . . .
Depending on where a woman is in her cycle, ECP will either:
1. Prevent ovulation
2. Prevent fertilization of an egg
3. Stop a fertilized egg from implanting into the uterine wall
Once the egg is implanted, ECPs will not work. They will not abort an established pregnancy.
Who shouldn't take it . . .
Most women can use ECPs safely, even women who can't normally take the birth control pill.
What are the side effects . . .
ECPs will sometimes cause:
1. Nausea
2. Headaches
3. Cramping
4. Vomiting
5. Dizziness
6. Breast tenderness
What women should consider before using ECPs . . .
How long ago she had intercourse: if longer than 72 hours, it will probably
not be effective. Whether or not she was using any methods of birth control: this
will help to determine whether or not she needs to use the ECP (i.e. broken condom = good idea
to use ECP, one or two missed Pills = not necessary).
When she is due to start her next period: if her period is due to start in less than 1 week, ECP may not be necessary.
Effectiveness Rate . . . >95%
Women should be aware of the fact that ECPs are not 100% effective. They may still become pregnant and should consider what their decision would be if that does happen. Women should also know that ECPs are only effective on past sexual encounters, not future ones, and it cannot be taken more than once a menstrual cycle.
Where to get it . . .
There are several places in Saskatoon where women can access ECPs at no charge (e.g./ City Hospital, Royal University Hospital, sometimes clinics). Always ask for a pro-choice doctor. Sexual Health Centre Saskatoon provides emergency contraceptive pills without consultation with the doctor. It is also available by prescription at most pharmacies at a cost ranging from $6.00 to $11.00. PPSC has a complete listing of where to get ECPs.
