A contraceptive implant is a small, flexible rod that is inserted under the skin of your upper arm to prevent pregnancy. The implant releases hormones (Progestin) into the bloodstream to prevent pregnancy.
The implant works by thickening the cervical mucus, which blocks sperm from reaching the egg, and by preventing ovulation (the release of an egg from the ovary). The implant also causes changes in the endometrial lining, which make it more difficult for a fertilized egg to implant in the uterus.
To use a contraceptive implant, a healthcare professional inserts the implant into the upper arm under local anaesthesia. The implant is left in place for a specified period of time, usually 3 years, depending on the type of implant. The implant can be removed at any time by a healthcare professional if the you want to become pregnant or if you experiences any adverse side effects.
Contraceptive implants are highly effective at preventing pregnancy, and they do not require daily attention like other forms of contraception. However, it is important to remember that contraceptive implants do not protect against STIs, so it is important to use a barrier method, such as a condom, to reduce the risk of STI transmission.
Common side effects of contraceptive implants include:
- Irregular bleeding or spotting
- Headache
- Nausea
- Acne
It is important to talk to a healthcare provider about the risks and benefits of a contraceptive implant, and to discuss any health conditions or medications that may affect its use.
