Precautions

Drug information provided by: Micromedex

If you will be using the etonogestrel implant for a long time, it is very important that your doctor check you at regular visits for any problems or unwanted effects that may be caused by this medicine.

If you become pregnant while using this medicine, you have a slightly higher chance of having an ectopic pregnancy (occurs outside the womb). Ectopic pregnancies can cause serious internal bleeding. Contact your doctor immediately to have the implant removed.

Tell your doctor if you are breastfeeding or planning to breastfeed. You may start using this medicine if you had a baby more than 4 weeks ago.

Etonogestrel implant will not protect you against HIV/AIDS or other sexually transmitted diseases. The use of latex (rubber) condoms or abstinence (not having sex) is recommended for protection from these diseases.

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

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

Using this medicine may increase your risk of blood clots in the legs (deep vein thrombosis), lungs (pulmonary embolism), brain (stroke), heart (heart attack), or eyes (blindness). Make sure your doctor knows at least 4 weeks before if you are going to have a surgery or will need to be on bed rest. Your risk of these serious medical problems is greater during surgery or bed rest, or if you smoke cigarettes.

This medicine may also increase your risk of having irregular monthly periods, ovarian cysts, high blood pressure, gallbladder problems, or liver tumors.

Call your doctor right away if you have pain or tenderness in the upper stomach; pale stools; dark urine; loss of appetite; nausea; unusual tiredness or weakness; or yellow eyes or skin. These could be symptoms of a serious liver problem.

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 you to get your eyes checked by an eye doctor (ophthalmologist).

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.

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.
