What are the long-acting reversible contraceptive choices?

There are four types of long-acting reversible contraception (LARC).

  • The contraceptive implant. A minor procedure under local anaesthetic is needed to insert the small, rod-shaped implant under the skin in your upper arm, where it remains. The implant releases a progestogen hormone. Each implant lasts three years. Read about the implante anticonceptivo.

  • The contraceptive injection. An injection of a progestogen hormone is given every three months (two months for one brand), most commonly into the muscle in your bottom. Read about the inyección anticonceptiva.

  • The intrauterine contraceptive device (IUCD). This is also known as 'the coil'. It sits inside the womb (uterus) and, once fitted, can stay in your womb for up to ten years. The device is called a coil because in the 1960s some devices were coil-shaped. Read about the dispositivo intrauterino.

  • El sistema intrauterino (SIU). This is a specific type of IUCD which releases a progestogen hormone into the womb. It can last for up to five years. Read about the sistema intrauterino (SIU).

LARCs are ideal for women who do not want a baby in the near future. This might be because you think you have completed your family and don't want more children, but want to keep your options open. Or it might be because you are young and not wishing to have children for some years to come. Or because you don't want children at all. Or because you are not currently in a position to have children, because of your job, relationship or finances. The great thing about LARCs is the word "reversible" - so if your situation changes, you can stop using them and become fertile again.

You don't need to take a tablet every day, so for most LARCs, you can forget about contraception for years at a time. This makes them more reliable (as they don't need you to remember, other than when they are due to be replaced).

The main downside is that they all require a small procedure of some sort. However, this does not have to be done very often, and provides long-term, reliable contraception once you have done it.

This is an individual choice. Different people will prefer different options. Pros and cons of each are weighed up in the separate leaflet called Contraception Methods, and there is plenty of information about each in their individual leaflets as linked above.

Preguntas frecuentes

What is the primary benefit of choosing long-acting reversible contraception over other methods?

The main benefit of LARCs is their reliability, as you don't need to remember to take a pill every day. Once in place, they provide contraception for years, meaning you can largely forget about it for extended periods.

How long does each type of LARC protect against pregnancy?

The contraceptive implant lasts for three years. The contraceptive injection needs to be given every three months (or two months for one brand). The intrauterine contraceptive device (IUCD) can stay in for up to ten years, and the intrauterine system (IUS) can last for up to five years.

Can I have children after using long-acting reversible contraception?

Yes, LARCs are 'reversible'. This means that if your circumstances change and you decide you want to have children, you can stop using them and become fertile again.

Are there any minor procedures involved with these types of contraception?

Yes, all LARCs require some form of minor procedure. For example, the implant is inserted under the skin, injections are given for the contraceptive injection, and the IUCD and IUS are fitted inside the womb. However, these procedures are not needed very often.

How often do I need to get the contraceptive injection?

The contraceptive injection is typically administered every three months, although one brand requires an injection every two months.

Are 'the coil' and the IUCD the same thing?

Yes, 'the coil' is another common name for the intrauterine contraceptive device (IUCD). It is called this because some of the original devices in the 1960s were coil-shaped.
