Nexplanon is considered a reversible and highly used measure for birth control. It can provide you protection for several years.  Before inserting Nexplanon, you have to undergo a pregnancy test to confirm your pregnancy.  Only after the confirmation, you can proceed with further procedures. After the test, you can implant it at any time of your menstrual cycle.

Health care professionals will clean your arm with some type of solution and you will be given an injection to avoid pain during implantation.  It is considered a non-dangerous one and as years pass by, the hormone level starts to drop which tends to become less effective. Once, effectiveness is completed, it can still release the hormone, but those will not serve any purpose.

People who use Nexplanon do not suffer from any side effects for the long term. Most of the minor effects go within three to four months once your body starts to adapt to the hormones. You will be monitored very accurately before discharging to home.  The implanted site will contain a pressure bandage for at least a day and a regular bandage for 2 or 3 days. You are restricted to do strenuous activities during these days as it may take a long to recover.

If it is implanted, and you could not feel it, visit your doctor immediately as there are chances of being pregnant.  Most people have common side effects in menstrual bleeding. Sometimes, it may take longer. It is strictly recommended to consult a doctor if you have any other health problems like liver or heart diseases.


As every treatment involves risk, few risks may be life-threatening to most people using the Nexplanon to prevent pregnancy, which should be discussed with your professionals before treatment. You may opt for other options too. Nexplanon must be inserted only by experts, nurse practitioners, or any gynecologist who has good experience to insert or remove the implant.

It cannot be brought from pharmacies like other birth control forms. Many women believe that by implanting Nexplanon, your body gains weight. Before proceeding with the treatment, ensure all the benefits and risks involved by consulting professionals and choose the right treatment.
