Implanon is a contraceptive implant consisting of a single rod and an applicator with which the drug is injected. Implanon subcutaneously affects the activity of the ovaries, suppresses the occurrence of ovulation, thereby preventing pregnancy at the hormonal level.

What are the contraceptive properties of Implanon and Implanon NKST based on?
The drug is available under two names. However, there are no differences in the composition. The active substance of Implanon and Implanon NKST is etonogestrel. It is this component that acts as a contraceptive that does not undergo biological decay.
The implant works to suppress ovulation. After administration, etonogestrel is absorbed into the blood, already from 1-13 days, its concentration in plasma reaches its maximum value, and then decreases and by the end of 3 years disappears.
During the first two years, the young woman does not have to worry about additional contraception. The drug works with 99% efficiency. In addition, experts say that it does not affect body weight. Also, with it, bone tissue does not lose mineral density, and thrombosis does not appear.
After removal of the implant, ovarian activity quickly returns to normal and the menstrual cycle is restored.
Implanon NCTS, in contrast to implanon, is more effective. Studies have shown that it affects the patient’s body by 99.9%. This may be due to the convenient applicator, which eliminates the possibility of incorrect or deep insertion.

How Implanon is administered
The procedure takes place in three stages:
The first is preparation
You, the patient, lie on your back, turn your left arm outward, and then bend at the elbow, as shown in the figure
The doctor marks the injection site and then wipes it with a disinfectant. A point is indicated approximately 8-10 cm above the inner epicondyle of the humerus.
The second is pain relief
There are two ways to administer anesthesia. Spray or inject 2 ml of lidocaine.
Third – the introduction of the implant
Strictly must be done by a doctor! His actions:
- Leaving the protective cap on the needle, visually examines the implant. By knocking on a hard surface, it hits the tip of the needle and then removes the cap.
- Using the thumb and forefinger, pulls the skin around the marked insertion site.
- The tip of the needle inserts at a 20-30 degree angle.
- Loosens the skin.
- Directs the applicator horizontally in relation to the hand and inserts the needle to its full depth.
- Holds the applicator parallel to the surface, breaks the bridge, and then gently presses down on the slider and pulls out slowly. During the injection, the syringe remains in a fixed position, the plunger pushes the implant into the skin, and then the syringe body is slowly withdrawn.
- Checks for the presence of an implant under the skin by palpation, in no case should you press on the obturator!
- Applies a sterile napkin and a fixing bandage.
Duration of drug administration – when can Implanon be administered?

When and how is Implanon replaced or removed?
The implant can be removed at any time only after consulting a doctor. Only a healthcare professional should remove or replace the implanon.
The removal procedure takes place in several stages. The patient is also prepared, the injection site is treated with an antiseptic, and then anesthesia is performed, and lidocaine is injected under the implant.
The removal procedure is carried out as follows:
- The doctor presses on the end of the implant. When a bulge appears on the skin, he makes a 2 mm incision towards the elbow.
- The medic pushes the obturator towards the incision. As soon as its tip appears, the implant is grasped with a clamp and slowly pulled on it.
- If the implant is overgrown with connective tissue, it is cut and the obturator is removed with a clamp.
- If the implant is not visible after the incision, the doctor gently grabs it inside the incision with a surgical clamp, turns it over and takes it in the other hand. With the other hand, separate the obturator from the tissue and remove.
Note that the size of the removed implant should be 4 cm. If a part remains, it is also removed.
- A sterile bandage is applied to the wound. The incision will heal within 3-5 days.
Replacement procedure carried out only after the removal of the drug. A new implant can be placed under the skin at the same location. Before the second procedure, the injection site is anesthetized.
