Should you switch to the contraceptive injection?
If the contraceptive pill isn't working for you – either because of its side effects, or simply because you're terrible at remembering to take it every day – it could be worth switching to the injection.
But changing contraception can be a big step, so it's important to make sure you do your research beforehand to find the right one for you. No idea where to start? Dr Nicola Read from Bupa UK shares her answers with Cosmopolitan UK to some of the most common questions women have before getting the contraceptive injection:
1. Why is it different to the Pill?
"This particular contraception is given in a liquid form and is injected into a muscle in either your arm, or buttocks." Dr Nicola explains. "Unlike the Pill, you don’t have to take it every day.
"The most common contraceptive injections in this country, Sayana Press and Depo-Provera, provide protection for eight to thirteen weeks.
"Additionally, if you’re not able to use oestrogen-based contraceptives, like the Pill, the injection is a great alternative, as it is progesterone-based."
2. Do I need to come off my current contraception before I have the injection?
"The injection is given when the risks of pregnancy are at their lowest. This means that if you’re currently using a contraceptive pill, you can have your first injection at any point during your cycle whilst continuing to finish your current pack of pills.
"If your current contraceptive is an IUD (intrauterine device, like the coil), you can have your first injection at any point within your cycle – then you can have your IUD removed after two weeks.
"For those thinking about getting the injection that aren’t currently using any other contraceptive, you should schedule your first injection with your GP during the first seven days of your period."
3. What are the side effects?
"Like all types of contraception, you may experience side effects. The most common is altered bleeding patterns (which is usually less bleeding!) and weight gain.
"Research has shown that the injection may be linked to a decrease in bone density, which usually recovers when you stop using the injection. If you have a family history of osteoporosis, have a chat with your GP as the injection might not be the right type of contraception for you.
"There are also some reports of headaches, fatigue, bloating and reduced sex drive, and any prolonged side effects should be reported to your GP."
4. How does it differ to my current contraception?
"The injection is convenient. It’s long acting, which means you only need to have it every two to three months. Providing the injection is received on time, you don’t need to worry about contraception until you’re due your next one.
"The injection might also suit those who don’t like the thought of having an implant or the coil, but struggle to remember to take the contraceptive pill every day!
"There are different types of injection – some are given by nurses or doctors, and others you can give to yourself after some training."
5. Is it likely to affect my mood/mental health?
"Like all the other hormonal-based contraceptive methods, the contraceptive injection can cause headaches and mood swings. Usually, these symptoms only occur during the first couple of months of use, whilst your body is adjusting to the change in hormones. But if they do continue beyond this, it’s best to check-in with your GP."
6. Can it cause me to gain weight?
"The injection has been associated with weight gain in some people; usually those who might be a little overweight to begin with."
7. How long do I need to wait before trying for a baby if I decide to come off?
"There’s no concrete answer here, as women’s fertility and periods vary for different people. Some may return quite quickly, but for others it can take up to a year for fertility levels to return to normal.
"Because of this, it might not be ideal for those who are thinking of starting a family in the next 1-2 years."
8. Is there a way of reversing the contraception?
"If used correctly, once you have your first injection, you’ll be protected against pregnancy for eight to thirteen weeks (depending on the brand of contraceptive injection used). This can’t be reversed, so if you’re experiencing any side effects they’ll likely continue throughout this period.
"Once the injection’s course has ended, the side effects should dissipate, but you’ll no longer be protected against pregnancy unless you start taking another contraceptive."
As with any health decision, it's important to sit down with your doctor and discuss all options first. Book an appointment through the NHS or Bupa to find out more information and for a personalised consultation.
