do not want your periods to change
take other medicines that may affect the implant
have unexplained bleeding in between periods or after sex
have severe liver disease
have breast cancer or have had it in the past
have a medical condition that may affect which contraception you can use – talk to your doctor or nurse about this
What if I’m taking other medicines?
Some medicines can stop the implant from working.
These include:
medication for HIV
medication for epilepsy
complementary remedies, such as St John’s Wort
some antibiotics, such as rifabutin or rifampicin
If you’re taking any of these medicines, you’ll need additional contraception. You may wish to change your form of contraception to one that isn’t affected by your medication.
Always tell your doctor that you’re using an implant if you’re prescribed any medicine.
Side effects of the contraceptive implant
