Reliable 3-Month Protection Without Daily or Weekly Maintenance

What is Contraceptive Injection?

The contraceptive injection delivers a controlled dose of progesterone into the body via intramuscular injection. This hormone prevents pregnancy by:

• Inhibiting ovulation (prevents the release of eggs)
• Thickening cervical mucus (makes it difficult for sperm to reach the egg)
• Thinning the uterine lining (reduces the chance of implantation)

It is a suitable option for individuals seeking discreet, long-acting birth control with minimal daily upkeep.
