It can be useful for women who can’t use contraception that contains oestrogen and can be taken out if you have side effects. A common side effect is that your periods stop (amenorrhoea). It’s not harmful, but you may want to consider this before deciding to have an implant.Most women can be fitted with the contraceptive implant but it may not be suitable if you:
don’t want your periods to change
some medicines can make the implant less effective. These include complementary remedies, such as St John’s Wort, some antibiotics such as rifabutin or rifampicintake and medicines for HIV, epilepsy and tuberculosis. If you’re taking any of these medicines, you’ll need additional contraception (such as condoms), or you may wish to use a different method of contraception that isn’t affected by your medicine.
have unexplained bleeding in between periods or after sex
have arterial disease or a history of heart disease or stroke
have liver disease
have breast cancer or have had it in the past
have a medical condition that may affect which contraception you can use – speak to your GP or practice nurse, or visit your nearest sexual health clinic to discuss further
