Implantable contraception often called the birth control implant is a small, flexible plastic tube that doctors put under the skin of a girl's upper arm. The tube releases hormones that can help protect against pregnancy for up to 3 years. The implanted tube slowly releases low levels of the hormone progestin to prevent ovulation the release of an egg during the monthly cycle.
If a girl doesn't ovulate, she can't get pregnant because there is no egg to be fertilized. The released progestin also thickens the mucus around the cervix.
This makes it hard for sperm to enter the uterus and reach any eggs that may have been released. The progestin also thins the lining of the uterus so an egg will have a hard time attaching to the wall of the uterus. Implantable contraception is a very effective method of birth control. Over the course of 1 year, fewer than 1 out of typical couples using the implant will have an accidental pregnancy.
The chances of getting pregnant increase if a girl waits longer than 3 years to replace the tube. So it's important to keep a record of when a tube was inserted, and:. In general, how well each birth control method works depends on a lot of things. These include whether a girl has any health conditions or is taking medicines or herbal supplements that might affect its use.
For example, some antibiotics or herbs like St. John's wort can affect how well implantable contraception works. Implantable contraception does not protect against sexually transmitted diseases STDs.
However, because a contraceptive implant prevents most pregnancies, women who use it are at lower risk of having an ectopic pregnancy than are other sexually active women who aren't using contraception. Your health care provider will evaluate your overall health before inserting the contraceptive implant. He or she will determine the appropriate timing for the insertion of the implant based on your menstrual cycle and your previous birth control method.
You may need to take a pregnancy test and use a nonhormonal backup method of contraception for one week. The contraceptive implant is inserted beneath the skin of the upper arm.
The implant releases a progestational hormone to prevent sperm from reaching the egg. You can have a contraceptive implant inserted during a visit to your health care provider's office. The actual procedure takes just a minute or so, though preparation will take a bit longer. You'll lie on your back with the arm that will receive the implant bent at the elbow and positioned near your head.
Your health care provider will locate a groove between the biceps and triceps muscles on the inner side of your upper arm. He or she will inject a local anesthetic and then use an applicator to insert the device just beneath your skin. Inserting the device too deeply makes removal difficult. Your health care provider will feel your arm to confirm the presence of the implant and have you do the same.
If necessary, he or she may also use an ultrasound or X-ray to confirm that the device has been inserted. Your health care provider will cover the insertion site with a small bandage. He or she may also apply a pressure bandage to minimize bruising. You can remove the pressure bandage in 24 hours, but keep the small bandage clean and in place for three to five days.
It's common to experience some degree of bruising, pain, scarring or bleeding at the insertion site. The contraceptive implant can prevent pregnancy for up to three years.
It must be removed and replaced at the three-year point to continue offering protection from unintended pregnancy. Your health care provider may recommend removing the contraceptive implant earlier if you develop:. To remove the device, your health care provider will inject a local anesthetic in your arm beneath the implant. He or she will make a small incision in your skin and will push the implant toward the incision until the tip is visible and can be grasped with forceps.
Your health care provider will then pull out the implant, close the incision and apply a pressure bandage. Contraceptive implant removal typically takes less than five minutes. If you choose, a new device can be implanted as soon as the original device is removed. It releases the hormone progestogen into your bloodstream to prevent pregnancy and lasts for 3 years. The implant steadily releases the hormone progestogen into your bloodstream, which prevents the release of an egg each month ovulation.
It also thickens the cervical mucus, which makes it more difficult for sperm to move through the cervix, and thins the lining of the womb so a fertilised egg is less likely to implant itself. You can have the implant put in at any time during your menstrual cycle, as long as you're not pregnant.
If the implant is fitted during the first 5 days of your menstrual cycle, you'll be immediately protected against becoming pregnant. If it's fitted on any other day of your menstrual cycle, you'll need to use additional contraception such as condoms for 7 days. If it's fitted before day 21 after the birth, you'll be immediately protected against becoming pregnant.
If it's fitted on or after day 21, you'll need to use additional contraception such as condoms for the next 7 days. The implant can be fitted immediately after a miscarriage or an abortion and you'll be protected against pregnancy straight away. A local anaesthetic is used to numb the area on the inside of your upper arm.
The implant is then inserted under your skin — it only takes a few minutes to put in and feels like having an injection. Nexplanon works for 3 years before it needs to be replaced. You can use this method until you reach the menopause, when a woman's monthly periods stop naturally.
The implant can be removed at any time by a specially trained doctor or nurse. It only takes a few minutes to remove, and a local anaesthetic will be used. The doctor or nurse will make a tiny cut in your skin to gently pull the implant out. If you're taking any of these medicines, you'll need additional contraception such as condoms , or you may wish to use a different method of contraception that isn't affected by your medicine.
Always tell your doctor that you're using an implant if you're prescribed any medicine. You can also ask them whether the medicine you're taking will affect the implant. In rare cases, the area of skin where the implant has been fitted can become infected. If this happens, you may need antibiotics.
