Depo Provera Birth Control Information
January 23, 2008
Depo Provera is a hormonal form of birth control that is administered via injection about every 3 months and keeps women from ovulating, thus preventing pregnancy. It consists of progestin without estrogen.
The advantage of Depo Provera is that it is 99% effective at preventing pregnancy when given on time. Some women also like the fact that they don’t have to think about birth control every day. On the other hand, it does require an office visit to get the shot.
Usually after the second shot, women will not have a menstrual period. Some women report spotting or irregular menstrual cycles.
Depo Provera is known to cause some users to calcium stored in their bones. Pfizer, the creators of the product, only encourage long-term use (2 years or more) of the method “only if other methods of birth control are not right for you.”
In addition, 2 out 3 women in clinical trials reported a weight gain of 5 pounds during the first year of use.
