Contraceptive injection

If you would like a non-invasive and discreet contraceptive method, the contraceptive injection may be suitable for you. The contraceptive injection is an injection of hormone that provides long acting protection from unplanned pregnancy. It works by slowly releasing the hormone progestogen into the body to prevent ovulation. Irregular bleeding is a possible side effect of the contraceptive injection, however, with time, no periods is common and may be an advantage for some. You should not use this contraceptive method if you do not want your periods to change. The contraceptive injection is a very effective family planning method (over 99% effective with perfect use) and is more reliable than the contraceptive pill, as you only need to remember to have the injection every 12 weeks, instead of taking a daily pill. It is important to have a repeat injection on time, every 12 weeks, otherwise it becomes ineffective; hence its effectiveness is only 94% with typical use. It doesn’t offer any protection against sexually transmitted infections or HIV/AIDS.

Long term use of the contraceptive injection may reduce the mineral content of bone in some women, which is likely to be reversible when the injections are stopped. Because of this, if you are under 18 or over 45, the injection may not be the first choice of contraception for you. It can also delay your return to normal rates of fertility.

Contraceptive injection: your questions answered

During your consultation your doctor will firstly discuss the advantages and disadvantages of the contraceptive injection and assess its suitability as a contraceptive method. Following the initial consultation and your consent, the doctor or nurse will administer a small, quick injection of the contraception into your buttock or into the muscle of your upper arm.
The most common side effect of the contraceptive injection is the occurrence of irregular bleeding patterns, especially following the first injection. After one or more injections many women experience lighter periods and in many cases periods may stop altogether. This is not harmful and is often seen as an advantage of the contraceptive injection.

Some women may experience longer periods or continual light bleeding for some weeks and in rare cases heavy bleeding may occur. A small amount of weight gain may occur with the contraceptive injection, but a large increase in weight is uncommon. Other side effects are uncommon but headaches, acne, moodiness, a loss of libido, bloating and fluid retention can occur for some women.

If the contraceptive injection is given within the first five days of the menstrual cycle (where day one is the first day of your period), then it is effective immediately. If it is given at another time during your menstrual cycle, another type of contraception (such as condoms) should be used for the next seven days to avoid unplanned pregnancy. Your doctor will discuss with you the best time to have the injection, as they first need to ensure you are not already pregnant.
The contraceptive injection is widely considered to be a safe method to use during breastfeeding from delivery.
A doctor’s prescription is required to obtain a contraceptive injection, which you can get from your local GP, sexual health clinic or Marie Stopes Australia clinic. Only a doctor or nurse should administer the injection. To make an appointment for a Marie Stopes contraceptive injection consultation, call 1300 003 707 or enquire online.
Each contraceptive injection will provide protection from pregnancy for a full 12 weeks only, so it’s important that you have regular injections every 12 weeks to avoid unplanned pregnancy. You should make regular, forward appointments with your doctor to ensure ongoing contraceptive cover. Ultimately it is your responsibility to make an appointment to visit your doctor.
Once the contraceptive hormone has been injected it cannot be reversed for 12 weeks and, due to a continuing low level of hormone in the body following the final injection, there may be a further delay in the return of the normal menstrual cycle. When you stop the contraceptive injections it may take many months for your periods to return to normal (an average of eight months) and up to 18 months for your fertility to return to normal. Despite this, it is important to start using another form of contraception within 12 weeks of the last injection if you do not want to get pregnant.
