Depo Shot (Depo-Provera)

• Progestin Birth Control Shot
• Received once every three months

How it works

• Progestin prevents pregnancy by stopping ovulation

• ​Shot is administered in either your arm or your buttocks 
• If you get your first shot within the first 7 days after the start of your period, you’re protected from pregnancy right away.
