How to use Etonogestrel

Nexplanon® is an implant that is surgically placed and removed under the skin of the upper arm by a trained healthcare provider. The implant is placed in the upper arm for 3 years and then removed by the end of the third year.

It is very important that you tell your doctor if you think you might be pregnant or if you missed a period before you receive this medicine. A pregnancy test will be done to make sure you are not pregnant before this medicine is inserted.

This medicine comes with patient instructions. Read and follow these instructions carefully. Ask your doctor or pharmacist if you have any questions.

The implant is usually inserted by your doctor within the first 5 days of your menstrual period.

After this medicine is inserted, your doctor should feel your arm to check that the implant is in the right place. You can also check it by gently pressing your fingertips over the insertion site. You should be able to feel the small rod. If you cannot feel the implant in your arm, you will need to use a non-hormonal birth control (such as condoms, spermicide) until your doctor confirms that the implant is in place.

Your doctor will treat the arm with numbing medicine and insert the implant with a special tool. The incision will be covered with 2 bandages. You may remove the top bandage after 24 hours. Keep the smaller bandage clean and dry and in place for 3 to 5 days.

Your doctor must remove this medicine after 3 years. If you would like to stop using this medicine, your doctor can remove it at any time. Do not try to remove the implant by yourself.

If you still want to prevent pregnancy after this medicine is removed, you should start using another form of birth control (eg, condoms, diaphragms, or spermicides) right away. If you still want to continue using this medicine, your doctor can insert a new implant under your skin after taking the old one out.

Do not eat grapefruit or drink grapefruit juice while you are using this medicine.

Warnings

It is very important that your doctor check your progress at regular visits to make sure this medicine is working properly and does not cause unwanted effects.

Tell your doctor if you have recently given birth. You may start using this medicine 4 weeks after giving birth.

Etonogestrel implant will not protect you from getting HIV/AIDS or other sexually transmitted diseases. Tell your doctor if you or your partner begins to have sexual intercourse with other people, or you or your partner tests positive for a sexually transmitted disease. If this is a concern for you, talk with your doctor.

Tell your doctor if you had an allergic reaction to numbing medicines (anesthetics) or skin cleansers (antiseptics). These medicines will be used when the etonogestrel implant is inserted into your arm.

This medicine may cause several problems related to insertion and removal, including pain, irritation, swelling, bruising, scarring, or other complications. Talk to your doctor about these possible risks.

Etonogestrel implant may break or bend while it is in your arm due to external forces (eg, manipulation of the implant or contact sports). A broken implant may move from the insertion site. Call your doctor if you feel that the implant may have broken or bent while in your arm.

You could have less bleeding or may even stop having periods while using this medicine. Call your doctor if you have a change from your regular bleeding pattern after you have had your implant for awhile, such as more bleeding or if you miss a period (and if you were having periods even with your implant).

Call your doctor right away if you think you have become pregnant while you are using this medicine. You may have a higher risk of an ectopic pregnancy (occurs outside the womb) if you get pregnant while your implant is in place. This can be a serious and life-threatening condition. It can also cause problems that may make it harder for you to become pregnant in the future.

Using this medicine may increase your risk of having blood clotting problems. Check with your doctor right away if you have pain in the chest, groin, or legs, especially the calves, difficulty with breathing, a sudden, severe headache, slurred speech, a sudden, a sudden loss of coordination, or vision changes while using this medicine.

This medicine may also increase your risk of having ovarian cysts, breast cancer, gallbladder problems, or liver tumors. Talk to your doctor if you have any concerns.

Check with your doctor right away if you have pain or tenderness in the upper stomach, pale stools, dark urine, loss of appetite, nausea, vomiting, or yellow eyes or skin. These could be symptoms of a serious liver problem.

This medicine may increase your weight. Your doctor may need to check your weight on a regular basis while you are using this medicine. Talk to your doctor about ways to prevent weight gain.

Your blood pressure might get too high while you are using this medicine. This may cause headaches, dizziness, or blurred vision. You might need to measure your blood pressure at home. If you think your blood pressure is too high, call your doctor right away.

This medicine may affect blood sugar levels. If you notice a change in the results of your blood or urine sugar tests, or if you have any questions, check with your doctor.

This medicine may also increase the amount of cholesterol and fats in your blood. If this condition occurs, your doctor may give you some medicines that can lower the amount of cholesterol and fats in the blood.

If you wear contact lenses and you have blurred vision, difficulty in reading, or any other change in vision while using this medicine, check with your doctor right away. Your doctor may want your eyes be checked by an eye doctor (ophthalmologist).

Before you have any medical tests, tell the medical doctor in charge that you are using etonogestrel implant. The results of some tests may be affected by this medicine.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal (St. John's wort) or vitamin supplements.
