A single-rod progestin implant, Implanon®, has been approved for birth control use in the US and elsewhere. A healthcare provider inserts it under the skin in the upper inner arm. It is effective for up to three years, and can be removed sooner if pregnancy is desired. Insertion and removal can be done in an office or clinic. Fertility returns rapidly after removal of the rod.

 

Irregular bleeding is the most bothersome side effect. Expect your menstrual periods to be irregular and unpredictable throughout the time you are Implanon. Some of the problems related to insertion are pain, irritation, swelling, or bruising of insertion site. This should only last a day or two and shouldn't interfere with your usual activities.
