IMPLANON®


What is IMPLANON®

Implanon

IMPLANON® is a type of birth control for women. It is a flexible plastic rod the size of a matchstick that is put under the skin of your arm.

IMPLANON® contains a hormone called etonogestrel. You can use a single IMPLANON® rod for up to three years. Because IMPLANON® does not contain estrogen, your healthcare provider may recommend IMPLANON® even if you cannot use estrogen.

Since 1998, there have been more than 4.5 million IMPLANON® units sold worldwide. It is a progestin-only method of birth control and does not contain estrogen. IMPLANON® does not contain latex or silicone and will not dissolve.

Birth control that lasts up to 3 years

  • Effective – IMPLANON® is more than 99% effective: the chance of getting pregnant is less than 1 pregnancy per 100 women who use IMPLANON® for 1 year when IMPLANON® is inserted correctly.a
  • Discreet – Most women can’t see IMPLANON® after insertion.
  • Long-acting – One IMPLANON® provides up to 3 full years of contraceptive protection

a IMPLANON® must be removed by the end of the third year and may be replaced with a new IMPLANON®. It is not known if IMPLANON® is as effective in very overweight women because studies did not include many overweight women. Tell your healthcare provider about any medicines you are taking, or intend to take, including over-the-counter medicines, herbal remedies, and prescription medicines. Certain medicines may make IMPLANON® less effective and you may need to use a barrier method of contraception as backup.

How does IMPLANON® work

IMPLANON® prevents pregnancy in several ways. The most important way is by stopping release of an egg from your ovary. IMPLANON® also changes the mucus in your cervix and this change may keep sperm from reaching the egg. Also, IMPLANON® changes the lining of your uterus.

How effective is IMPLANON®

If IMPLANON® is inserted correctly, your chance of getting pregnant is very low (less than one pregnancy per 100 women who use IMPLANON® for one year). IMPLANON® must be removed by the end of the third year and may be replaced with a new IMPLANON®. It is not known if IMPLANON® is as effective in very overweight women because clinical studies did not include many overweight women. Certain medicines may make IMPLANON® less effective, and you may also need to use a barrier method of contraception while you are using these medicines.

How do I use IMPLANON®

Your healthcare provider will insert (or remove) IMPLANON® in a minor surgical procedure in his or her office. IMPLANON® is inserted just under the skin on the inner side of your upper arm.

The timing of insertion is important. Depending on your history, your healthcare provider may ask you to

  • Have a pregnancy test before insertion
  • Schedule the insertion at a specific time of your cycle (for example, within the first days of your regular menstrual bleeding)
  • Use a backup method of birth control, such as condoms, for seven days after IMPLANON® insertion

Who should not use IMPLANON®

IMPLANON® is not for everyone. Do not use IMPLANON® if you:

  • Are pregnant or think you may be pregnant
  • Have or have had serious blood clots, such as blood clots in your legs (deep venous thrombosis), lungs (pulmonary embolism), eyes (retinal thrombosis), heart (heart attack), or head (stroke)
  • Have unexplained vaginal bleeding
  • Have liver disease
  • Have or have had breast cancer
  • Are allergic to anything in IMPLANON®

What if I want to become pregnant

Once IMPLANON® is successfully removed, your ability to get pregnant usually returns quickly. Some women have become pregnant within days after removal of IMPLANON®

Can I use IMPLANON® when I am breast feeding

Based on a small study, you may start IMPLANON® if you are breast feeding and if you delivered your baby more than four weeks ago. A small amount of the active substance of IMPLANON® passes into the breast milk. The health of breast fed children whose mothers were using IMPLANON® has been studied up to three years of age in a small number of children. No effects on the growth and development of the children were seen. If you are breast feeding and want to use IMPLANON®, talk with your healthcare provider.

What are the possible complications of the insertion procedure

Rarely, IMPLANON® is not inserted at all due to a failed insertion or if the implant has fallen out of the needle. If this happens, you may become pregnant. After insertion, and with direction from your healthcare provider, you should be able to feel IMPLANON® under your skin. If you can’t feel IMPLANON®, tell your healthcare provider.

Some other problems related to insertion include:

  • Pain, irritation, swelling, or bruising
  • Scarring, including a thick scar called a keloid
  • Infection
  • IMPLANON® breaks, making it difficult to remove
  • Expulsion of the implant (occurs rarely)

What are the most common side effects I can expect while using IMPLANON®

The most common side effect of IMPLANON® is a change in your menstrual periods. In studies, about 10% women stopped using IMPLANON® because of bleeding problems. Expect your menstrual periods to be irregular and unpredictable throughout the time you are using IMPLANON®.

You may have more bleeding, less bleeding, or no bleeding. The time between periods may vary, and in between periods you may have spotting.

Talk with your healthcare provider if you think you may be pregnant or if our vaginal bleeding is heavy and prolonged

Besides irregular bleeding, some of the most frequent side effects that caused women to stop using IMPLANON® in studies were:

  • Mood swings
  • Weight gain
  • Headache
  • Acne
  • Depression
  • The most common side effects reported by women using IMPLANON® in clinical trials were
  • Irregular bleeding
  • Vaginitis (inflammation of the vagina)
  • Breast pain

How will my bleeding change

Expect your menstrual periods to be irregular and unpredictable throughout the time you are using IMPLANON®. You may have more bleeding, less bleeding, or no bleeding. The time between periods may vary, and, in between periods, you may have spotting.

You should discuss any questions you may have about irregular bleeding with your healthcare provider. Be sure to let him or her know if you think you may be pregnant or if your bleeding is heavy and prolonged.
