Choosing which type of contraception to use is a very personal decision. There are several factors to take into account when choosing a method of contraception.
How effective is the contraceptive injection?
The contraceptive injection is over 99% effective, which means that less than one woman in 100 will become pregnant while using this method of contraception each year. This compares favorably to other forms of contraception such as condoms, which have an effectiveness of approximately 98% when they are used according to the instructions.
Types of contraceptive injection
There are two types of contraceptive injection, which are called Depo-Provera and Noristerat. Depo-Provera gives slightly longer-lasting protection against pregnancy than Noristerat – you only need to get the Depo-Provera injection once every three months, whereas the Noristerat injection has to be repeated every two months. Both types of contraceptive injection are injected by a doctor or nurse at a contraceptive clinic, GP’s surgery, or sexual health clinic.
How does it work?
The contraceptive injection is a hormonal method of contraception. It changes the levels of natural hormones in the body to stop sperm from reaching and fertilising the egg. It also makes the lining of the womb thinner, which stops a fertilised egg from implanting and also has the added bonus of making periods lighter and less painful.
What’s good about it?
The advantages of the contraceptive injection are numerous. Firstly, as mentioned it is very reliable and unlike the pill, it is not affected by other medicines or by short-term sickness or diarrhoea. With the injection, you only need to get to be injected once every two or three months. So fi you are terrible at remembering to take your pill, this method could be for you
A disadvantage of the contraceptive injection is that it can make your periods irregular or make them stop altogether. Some women consider having fewer or no periods to be an advantage but others feel it is unnatural. Depo-Provera is associated with weight gain, although this can be controlled by being careful with your diet. You should be aware that once you have had the injection, you will not be able to remove the hormones from your system, so any side effects that you might have will last for two or three months.
Its important to mention that the contraceptive injection is that it does not offer any protection from sexually transmitted diseases, also known as STDs. Whenever you have sex with a new partner, you should protect yourself from infection by using a condom, or wait until you have both been tested for STDs at a sexual health clinic before you have sex with each other.
You can use the contraceptive injection together with condoms to make sure that you are well-protected against both pregnancy and STDs. Alternatively, you can use the contraceptive injection as your only method of contraception if you are in a relationship with someone who you know is free from diseases and neither of you have any other sexual partners.
