| Basic Information |
|
| Description |
- The goal of contraception (or birth control) is to prevent an
unplanned pregnancy. The majority of methods of contraception enable
sexually active couples to temporarily avoid pregnancy. Permanent
birth control is accomplished through sterilization. Be sure you
know and understand the different types of birth control available
to you, the risks and benefits of each, and any side effects, so
that you can make an informed choice.
- The most widely used injectable form of birth control is the
hormone medroxyprogesterone (Depo-Provera). The regimen consist
of an injection every 90 days. It suppresses ovulation to some extent,
makes the mucus of the cervix unable to be penetrated by viable
sperm and renders the lining of the uterus unreceptive to a fertilized
egg.
|
| Advantages |
- It is very effective for birth control (over 99%); one of the
most effective forms available.
- Quickly and easily administered by a health care provider.
- The hormone used, progestin, provides a birth control option
for women who cannot take estrogen hormones that are used in oral
contraceptives.
- The injections require no daily routine.
- Freedom from concern and enjoyment of spontaneous sexual intercourse.
- Future fertility does not appear to be affected, but it may take
several months to one year for ovulation to occur once the injections
are discontinued.

injections. These include allergies, liver disorder, cancer or a

Instructions for use
- The injections will be prescribed for you after the health care
provider has studied your medical history and the results of a physical
examination.
- The first injection is often given during the first five days
of the menstrual period so that pregnancy has been ruled out.
- The injections are injected into a muscle once every three months
(usually a large muscle such as the buttocks muscle is used). The
contraceptive levels of hormone persist for up to four months (allowing
a two- to four-week margin of safety).
