How soon does the birth control shot start to work?

Great question! Let’s start by talking about what the birth control shot is.

The birth control shot, or Depo-Provera, is a hormonal birth control method used to effectively prevent pregnancy. The hormones prevent ovulation – the process when the ovaries release an egg – and thicken cervical mucus.

With that being said, Depo will be 97-99% effective in preventing pregnancy. The shot is an injection of hormones given every three months; only four times a year! The shot is given by a medical provider into your arm or hip. It will be most effective if taken on time, every time.

Now that we’ve discussed what the shot is, let’s talk about when it becomes effective!

When someone starts a new hormonal method of birth control (like the Depo shot), they need to use a back up method (like condoms or practicing abstinence) for one week before that method will be effective. After that first week, the hormones will be integrated into the body and can help prevent pregnancy up to 99% when taken correctly.

It’s also a great idea to consider condoms  and dental dams when you’re engaging in sexual activities. If used correctly and consistently, condoms can help prevent pregnancy and STI transmission by up to 98%! Teen Clinic offers free condoms and dental dams.
