CHECK-UP:How does an implant contraception work and will it hurt?
I HAVE been taking the pill for a number of years but have a tendency to forget it at least once or twice a month. Having discussed alternative methods with my doctor, he suggests I change to an implant contraceptive – Implanon. Although I understand a tiny rod will be implanted in my arm, will it hurt to have it done?
A contraceptive implant is a small plastic rod about the size of a matchstick that is inserted under the skin of the upper arm.
The implant releases a hormone that works to prevent ovulation. It also causes changes in the lining of the uterus and the cervical mucus to help prevent pregnancy. Implanon is inserted just under the surface of the skin over the large muscle in the upper arm – the biceps.
Under local anaesthetic, a sterile, preloaded applicator is used to insert the implant under the skin. No incision needs to be made, and the implant can be inserted or removed in a few minutes.
For how long does each implant work and what happens if I want to get pregnant?
The implant protects against pregnancy for three years, during which a woman normally does not have to do anything else to prevent pregnancy.
An implant may be a good option for women who find daily methods of birth control inconvenient or who have had difficulty remembering to take their oral pill.
It is also a good choice for women who cannot use contraceptive methods that contain oestrogen, such as those who are breastfeeding or have certain health problems. A woman can become pregnant soon after the implant is removed.
Are there side effects and risks associated with this type of contraceptive method?
Although the implant is a very effective method of birth control, the most common side effect of using a contraceptive implant is irregular bleeding.
While this tends to settle after six to nine months’ use, some women may find they stop bleeding altogether. For some women the implant may actually reduce the symptoms of painful periods. Other side effects can include pain, irritation or infection at the insertion site.
Headaches, abdominal pain and vaginitis have been reported, as has breast tenderness and weight gain. Some users experience mood changes, decreased libido and hair loss after using an implant form of contraceptive. Although rare, if pregnancy occurs while the implant is inserted, there is an increased risk of it being an ectopic pregnancy.
