How effective is the Depo shot and how soon can I be protected to have intercourse?

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.

It’s good to know that when it comes to STIs, there are four modes of transmission.  They are…

  • Blood
  • Semen
  • Vaginal fluids
  • Skin to skin contact

If you are having any types of sex where these modes may come into play, barrier methods like condoms and dental dams will help reduce the risk of STI transmission.
