Contraceptive implants are devices specifically designed to be implanted into a woman's body for a long time to provide contraceptive protection. There are two main types of implantable contraceptives: intrauterine devices (IUDs) and subdermal implants.
Intrauterine devices are inserted into the uterus and are divided into two types: hormonal and copper. Subcutaneous contraceptive implants are hormonal contraceptives that are implanted under the skin on the inside of the upper arm. We will talk about them in this article.
What is a subdermal contraceptive implant?
Subcutaneous The implant is a hormonal contraceptive. It contains a progestin -based active substance , etonogestrel , which is gradually released into the woman's body, thereby providing a contraceptive effect. The subcutaneous contraceptive is soft and flexible, made of plastic that does not dissolve in the body, namely ethylene vinyl acetate copolymer , its length is 4 centimeters, and its diameter is 2 millimeters.
How does a contraceptive implant work?
Etonogestrol works primarily by inhibiting ovulation. In addition, the active substance causes changes in the cervical mucus, making it thicker and thus making it more difficult for sperm to pass through.
subcutaneous implant is loaded into a sterile, disposable applicator. It must be implanted at a specific time, which may vary depending on whether the patient is switching from another hormonal contraceptive to this implant . After determining the implantation time, the doctor injects a local anesthetic. The injection site is the inner surface of the upper arm.
Once installed, the implant provides protection against unwanted pregnancy for three years. However, if the patient is overweight, the doctor may recommend replacing the implant at shorter intervals.
Although the device should not cause discomfort, it should be palpable and it is important to check for its presence regularly. If the rod is not palpable, you should immediately notify your doctor. In addition, if there is any doubt about the presence of the contraceptive in place, it is recommended to use barrier methods of contraception.
Before using a contraceptive implant the woman should undergo examinations to identify contraindications. In this regard, it is extremely important that the woman informs the doctor about any illnesses she has. She should also inform if she is taking any medications, herbal or homeopathic remedies, etc.
Side effects: what to expect?
A woman may react differently to the implant, experiencing side effects of varying types and intensities, or none at all. In any case, the most common side effects include:
• headache;
• changes in menstrual bleeding, both in frequency and in duration and intensity;
• amenorrhea;
• soreness of the mammary glands.
Acne ; weight gain; increased appetite; emotional lability; abdominal pain; pain and/or reactions at the implantation site may also occur .
When should you not use a contraceptive implant?
The use of the implant is contraindicated in all of the following cases: allergy to etonogestrel ; thrombosis; liver disease; vaginal bleeding of unknown origin.
For more detailed information, we recommend that you consult a gynecologist at the Bogolyuby Medical Center and be sure to carefully read the instructions for use of the prescribed contraceptive.
