Depo Provera Injection (Medroxyprogesterone): Injection for Birth Control

Depo-Provera Injection is a prescription medicine used primarily for contraception (birth control). It works by preventing ovulation and altering the uterine lining, making it difficult for sperm to reach the egg or for an egg to implant. This injection is also used in treating abnormal uterine bleeding and endometriosis.

Uses of Depo-Provera Injection:

• Long-term contraception (pregnancy prevention)
• Treatment of abnormal uterine bleeding
• Management of endometriosis

How Depo-Provera Injection Works:

Depo-Provera contains medroxyprogesterone acetate, a synthetic progestin that mimics the action of the natural hormone progesterone. It prevents the release of eggs from the ovaries, thickens cervical mucus to block sperm, and alters the uterine lining to prevent implantation. The injection provides effective contraception for up to 12 weeks.

How to Use Depo-Provera Injection:

This injection is administered by a healthcare provider—do not self-administer. It is given every 12 weeks (3 months) into a muscle, usually in the upper arm or buttock. Your doctor will determine the correct schedule and dosage for you.

Benefits of Depo-Provera Injection:

• Highly effective birth control lasting up to 12 weeks per dose
• Convenient—no daily pills or frequent doctor visits
• Helps reduce heavy or painful periods
