Implant

The contraceptive implant is a small flexible tube about 40mm long that's inserted under the skin of your upper arm. It's inserted by a healthcare professional and lasts for three years. The implant is a long-acting reversible method of contraception (LARC).

What are the benefits of using an implant?

  • It's more than 99 per cent effective when used correctly.
  • It does not interrupt sex.
  • It is safe to use while breastfeeding.
  • It may reduce heavy or painful periods after the first year of use.
  • After insertion, you should be able to carry out normal activities.
  • It's useful for women who know they don't want to get pregnant for a while.
  • Once in place, you don't have to think about contraception for three years. 
  • It can be useful for women who can't use contraception that contains oestrogen. 
  • It's useful for women who find it difficult to take a pill at the same time every day. 
  • If you have side effects, it can be taken out.

Things to consider

  • The implant does not protect against sexually transmitted infections.
  • When it's first put in, you may feel some bruising, tenderness or swelling around the implant.
  • In the first year after having it fitted, your periods may become irregular, lighter, heavier or longer.
  • A common side effect of the implant is that your periods stop.
  • Some medications can make it less effective.
