Contraceptive Injection
There are two types of contraceptive injection: Depo-Provera which lasts for up to 12 weeks and Noristerat which lasts for 8 weeks. The contraceptive progestogen is injected into your buttock and this is released slowly over a period of two to three months.
Injectable contraception is extremely convenient as you are protected as soon as you have the injection. They work by releasing a hormone into your body which prevents pregnancy by stopping the ovulation process. The injections are greater than 99% effective.
However, if you are planning to become pregnant in the coming year or two, these contraceptives are not recommended. It can take up to two years for the body to readjust and get back to a normal reproductive pattern.
Injectable contraceptives can have side effects such as irregular bleeding (your periods may stop altogether), weight gain or headaches. If you experience any of these symptoms, consult with your doctor.
Injectable contraceptives offer no protection against sexually transmitted infections.
