In this session, we will be discussing the consumer medication information for the medroxyprogesterone contraceptive injection, trade name Depo-ProveraTM.
What it’s for & How to take
Medroxyprogesterone contraceptive injection is hormonal birth control. If you are using this medication for a reason other than birth control, talk about it with your doctor.
Progestin-only hormone therapy prevents pregnancy by changing the environment in the womb. This medication makes it difficult for the sperm to fertilize an egg, or for a fertilized egg to attach to the wall of the womb.
Progestin-only therapy is more effective birth control than condoms or diaphragms; however, it is not as effective as estrogen/progestin combination therapy because it does not consistently prevent ovulation. This therapy is usually used by women who are unable to take estrogens for one reason or another.
This medication is given every 3 months as an intra-muscular injection by your health care provider. Your first injection should be given during the first 5 days of your menstrual period to assure you are not pregnant. Your doctor will discuss with you the best time to receive your injection.
Missing a dose of this medication is when you have gone more than 13 weeks without an injection. If you have gone more than 13 weeks since your last injection, use a backup form of birth control such as a condom or spermicide until you visit your health care provider and get your next injection.
