Side effects and risks of non-hormonal contraception

Non-hormonal methods of contraception

Some methods of contraception do not contain hormones (they’re non-hormonal).

Non-hormonal methods are:

  • condoms, which also help prevent sexually transmitted infections (STIs)
  • IUD (copper coil)
  • diaphragm
  • cap

Side effects of non-hormonal contraception

Side effects depend on the method of contraception.

An IUD (copper coil) can:

  • cause pain in your lower tummy or back for a few days after it is fitted
  • make your periods heavier or more painful – this usually gets better after a few months

If you use a diaphragm or cap:

  • the spermicide you need to use can irritate your vagina
  • you may be more likely to get a urinary tract infection (UTI) such as cystitis

Risks of non-hormonal contraception

There's a small risk that you may get an infection after having an IUD fitted.

There's a rare risk the IUD can fail, and you can get pregnant. If this happens, there's an increased risk of having an ectopic pregnancy.
