What is the contraceptive injection?
The contraceptive injection is given in the upper arm or buttock every 12 weeks. It contains the hormone progestin, which prevents ovulation.
The contraceptive injection available in Norway is called Depo-Provera (in Norwegian, felleskatalogen.no). One injection lasts for three months and costs approximately NOK 100.
The injection must be administered by a healthcare professional, such as a doctor or public health nurse.
Cheaper contraception for those under 22
You may be eligible for free or discounted IUDs and contraceptive implants. Additionally, you can get a six-month supply of birth control pills at a reduced cost.
Side effects of the contraceptive injection
Irregular menstruation
Irregular bleeding is a common side effect during the first few months. Over time, menstruation may stop altogether. The longer you use the injection, the more likely it is that your periods will cease.
Osteoporosis (bone loss)
Contraceptive injections may reduce bone density, which can increase the risk of osteoporosis and bone fractures later in life. For most young women, other contraceptive methods may be more suitable.
Cardiovascular side effects
If you are at risk for cardiovascular disease, it may be better to choose another progestin-based contraceptive method, such as the hormonal IUD.
Find the right contraception
All contraceptive methods offer good protection against pregnancy, but they differ in how they are used and in their side effects.

It may take time to become pregnant
If you have used the contraceptive injection for a long time, it may take a while for your fertility to return. This is because the effects of the injection can persist after you stop using it. It typically takes around six months for ovulation to resume after discontinuation of the injection.
