Depot Contraception Injection

Long-Acting Reversible Contraception

Depot Contraception Injection

Depot contraception is a 99.8% effective form of birth control, which involves receiving a hormonal injection, typically containing progestin, every three months. The hormone in the injection suppresses ovulation, preventing the release of eggs from the ovaries. It also thickens the cervical mucus, making it difficult for sperm to reach the uterus and fertilise an egg. Additionally, it can thin the lining of the uterus, making it less receptive to implantation.


The injection is usually administered in the upper arm or buttocks, and it is important to remember to have an injection every three months – or the specified duration – for pregnancy prevention.

Menstrual cycles can be regulated, menstrual cramps reduced, and heavy or irregular periods relieved through depot contraceptive injections.

While side effects vary, some women may experience changes in menstrual bleeding patterns, such as irregular or unpredictable bleeding. Some individuals may also experience weight gain, breast tenderness, or mood changes as side effects of this injection.
