Contraceptive injection

How effective is it?

The Contraceptive Injection is over 99% effective. Less than one woman in 100 will get pregnant in a year.

How does it work?

The Contraceptive Injection releases the hormone progestogen which stops ovulation, thickens cervical mucus to prevent sperm reaching an egg, and thins the lining of the uterus (womb) to prevent a fertilised egg implanting.

What are the advantages?

We supply the Contraceptive Injection Depo-Provera.  It lasts for 12 weeks.
It may protect against cancer of the uterus, and offers some protection from pelvic inflammatory disease. You don’t have to think about contraception for as long as the injection lasts.

What are the disadvantages?

Periods may stop, be irregular or longer.
Periods and fertility may take time to return after stopping the Contraceptive Injection.
Some women gain weight.
Some women report having headaches, acne, mood changes and breast tenderness.

Anything else I should know?

The Contraceptive Injection cannot be removed from the body so any side-effects may continue for as long as it works and for some time afterwards.
The Contraceptive Injection is not affected by other medicines.
