Etonogestrel
The patient will receive a Patient Warning Card from their doctor, which contains important information that they should know. The card should be kept in a safe place and shown during each visit related to the use of the subcutaneous implant.
Implanon NXT is a contraceptive subcutaneous implant placed in a single-use applicator. The safety and efficacy of the medicinal product have been established in women aged
The subcutaneous implant is inserted directly under the skin. The active substance, etonogestrel, works in two ways:
As a result of its action, Implanon NXT prevents pregnancy for a period of three years, although if the patient is overweight, the doctor may recommend earlier replacement of the subcutaneous implant. Implanon NXT is one of several methods of preventing pregnancy. Another commonly used contraceptive method is the combined oral contraceptive pill. Unlike the combined oral contraceptive pill, Implanon NXT can be used by women who cannot or do not want to use estrogens. When using Implanon NXT, there is no need to remember to take a daily pill. This is one of the reasons why Implanon NXT is considered a very reliable method (over 99% effective). In rare cases, it has been observed that the subcutaneous implant was not inserted correctly or was not inserted at all. This can result in an unplanned pregnancy. During the use of Implanon NXT, menstrual bleeding may change or not occur at all, may occur irregularly, less frequently, more frequently, be prolonged, or rarely be very heavy. Based on the course of bleeding during the first three months, the patient can determine the course of subsequent bleeding. Painful menstruation may be alleviated. It is possible to stop using Implanon NXT at any time (see also: "Stopping the use of Implanon NXT").
Implanon NXT should not be used if any of the following conditions are present. The doctor should be informed about their occurrence before inserting Implanon NXT. The doctor may advise a non-hormonal contraceptive method.
Before starting to use Implanon NXT, the doctor, pharmacist, or nurse should be consulted. If Implanon NXT is used in the presence of any of the diseases listed below, close medical supervision is required. The attending doctor will explain the course of action. Before inserting Implanon NXT, the doctor should be informed about their occurrence. The doctor should also be contacted if any of the following diseases occur or worsen during the use of Implanon NXT:
The following information is based on clinical trials in women using daily combined oral contraceptives containing two different female hormones ("oral contraceptive pill"). It is not known whether these observations also apply to women using other hormonal contraceptives, such as implants containing only progestogen. Breast cancer was diagnosed slightly more often in women using oral contraceptive pills, but it is not known whether this was caused by their use. For example, it is possible that tumors are detected more often in women using combined oral contraceptive pills because they are examined by a doctor more often. The increased frequency of breast cancer decreases gradually after stopping the use of combined oral contraceptive pills. It is very importantfor the patient to regularly examine her breasts. If she finds a lump, she should contact her doctor.The patient should inform her doctor about the occurrence of breast cancer in her close relatives. In rare cases, benign and very rarely malignant liver tumors have been found in patients using combined oral contraceptive pills. If the patient experiences severe abdominal pain, she should contact her doctor immediately.ThrombosisIn venous thrombosis, blood clots form in the veins. They can occur, for example, in the veins of the lower limbs, lungs (pulmonary embolism), or other organs and parts of the body. A blood clot can also block an artery (so-called arterial thrombosis), which can lead to a heart attack or stroke. The use of combined hormonal contraceptives increases the risk of such blood clots compared to women who do not take any combined hormonal contraceptives. This risk is not as high as the risk of blood clots in pregnant women. It is believed that the risk in women using only progestogens, such as Implanon NXT, is lower than in women using combined oral contraceptive pills containing estrogens .In women using etonogestrel implants, cases of blood clots have been reported, such as pulmonary embolism, deep vein thrombosis, heart attack, and stroke, but available data do not indicate an increased risk of these events in women using the subcutaneous implant.
the patient should contact their doctor immediately(see also "When to contact a doctor").
During the use of Implanon NXT, as with other progestogen-only contraceptives, menstrual bleeding may be irregular. The frequency (absence of bleeding, rare bleeding, more frequent or prolonged bleeding) and intensity (increased or decreased) of menstrual bleeding may change. Absence of menstruation was observed in 1 in 5 women, while in another 1 in 5 women, more frequent and/or prolonged menstrual bleeding was observed. Very heavy bleeding has been observed occasionally. In clinical trials, irregular menstrual bleeding was the most common reason for discontinuing the subcutaneous implant (about 11%). Based on the course of bleeding during the first three months, women can determine the course of subsequent bleeding. Changes in bleeding patterns do not mean that Implanon NXT is not suitable for the patient and does not show contraceptive efficacy. Generally, no special actions are required. However, if bleeding is very heavy or prolonged, the doctor should be contacted. Events related to the insertion and removal of the implantAs a result of improper insertion of the implant or external force (e.g., manipulation of the implant or contact sports), the subcutaneous implant may move in the arm relative to the insertion site. In rare cases, subcutaneous implants have been found in blood vessels of the arm or in the pulmonary artery (a blood vessel in the lungs). In cases where the subcutaneous implant has moved relative to the insertion site, locating the implant may be more difficult, and removal may require a larger incision or surgical procedure performed in a hospital. If the subcutaneous implant cannot be located in the arm, healthcare professionals may perform a chest X-ray or other imaging test. If the implant is located in the chest, surgery may be necessary. If the subcutaneous implant cannot be located and there is no evidence that it has been expelled, the contraceptive effect and the risk of progestogen side effects may last longer than the woman desires. If the subcutaneous implant is not palpable at any time, the doctor should be contacted as soon as possible. Psychiatric disordersSome women using hormonal contraceptives, including Implanon NXT, have reported depression or low mood. Depression can be severe and sometimes lead to suicidal thoughts. If mood changes and symptoms of depression occur, the doctor should be contacted as soon as possible for further medical advice. Ovarian cystsSmall fluid-filled blisters can develop in the ovaries during the use of contraceptive methods containing low doses of hormones. These are ovarian cysts. They usually disappear on their own. Occasionally, they can cause mild abdominal pain. Only in rare cases can they pose a more serious problem. Fracture or bending of the implantFracture or bending of the subcutaneous implant in the patient's arm should not affect its function. Fracture or bending of the subcutaneous implant may be caused by external forces. A fractured subcutaneous implant may move relative to the insertion site. If there are any questions, the doctor should be contacted.
The doctor should always be informed about medicines or herbal products currently used by the patient. The doctor of another specialty or the dentist prescribing other medicines (or pharmacist) should also be informed about the use of Implanon NXT. They may inform about the need to use an additional contraceptive method (e.g., a condom), and if so, for how long, as well as whether it is necessary to modify the use of another medicine. Some medicines
This applies to medicines used to treat:
Implanon NXT may affect the action of other medicines, such as:
Before taking any medicine, the doctor or pharmacist should be consulted.
No effect of food and drink on the action of Implanon NXT has been demonstrated.
Implanon NXT should not be used in pregnant women or in suspected pregnancy. If there is any doubt as to whether the woman is pregnant, a pregnancy test should be performed before starting to use Implanon NXT. Implanon NXT can be used during breastfeeding. Although a small amount of the active substance of Implanon NXT passes into breast milk, it does not affect the secretion and quality of breast milk, as well as the growth and development of children. During breastfeeding, before using this medicine, the doctor should be consulted.
The safety and efficacy of Implanon NXT have not been studied in adolescents under the age of 18.
No effect of Implanon NXT on alertness and concentration has been demonstrated.
Before inserting Implanon NXT, the doctor will take a medical history and measure the patient's blood pressure, and if necessary, order additional tests. If Implanon NXT is inserted, the patient may be asked by the doctor to undergo routine medical examinations after a certain period from the insertion. The frequency and purpose of these visits will depend on the individual needs of the patient. Healthcare professionals should palpate the implant during each follow-up visit.
Implanon NXT should be inserted and removed only by a doctor familiar with the procedure, as described below in the leaflet. The doctor will decide on the most appropriate time for insertion, depending on the individual situation of the patient (e.g., the currently used contraceptive method). If the patient is switching from a hormonal contraceptive method to a subcutaneous implant, it should be inserted between the 1st and 5th day of the natural menstrual cycle to ensure that the patient is not pregnant. If the implant is inserted after the fifth day of the menstrual cycle, the patient should use an additional contraceptive method (e.g., a condom) for the first 7 days after insertion. Before inserting and removing Implanon NXT, the attending doctor will administer local anesthesia. Implanon NXT is inserted directly under the skin on the inner side of the arm of the non-dominant hand (the hand that is not used for writing). A description of the technique for inserting and removing Implanon NXT can be found in section 6.
After the procedure, it is recommended that the patient palpate the implant to check its presence. A properly inserted implant should be palpable by both the healthcare professional and the patient, who should feel both ends of the implant between the thumb and index finger. It should be noted that palpation does not provide 100% certainty that Implanon NXT has been inserted. If the implant is not palpable immediately after insertion or at any time, the doctor should be contacted as soon as possible. In case of any doubts, a barrier method of contraception (e.g., a condom) should be used until the presence of the implant is confirmed. Once the implant has been located, it should be removed.
To help the patient remember when and where Implanon NXT was inserted and when it should be removed at the latest, the doctor will provide a Patient Warning Card with this information. The Patient Warning Card also contains instructions for the patient to palpate the implant from time to time to ensure that she feels its location. The patient should contact the doctor as soon as possible if she cannot feel the implant at any time. This card should be kept in a safe place! The Patient Warning Card should be shown to healthcare professionals during each visit related to the use of Implanon NXT. If the patient wants to replace Implanon NXT, a new implant can be inserted immediately after the removal of the previous one. The new implant can be inserted in the same arm and in the same location as the previous one, provided that the previous insertion site was correct. The attending doctor will provide advice.
It is possible to stop using Implanon NXT at any time. If the implant is not palpable, healthcare professionals may determine the location of the implant using X-ray, ultrasound, or magnetic resonance imaging. Depending on the exact location of the implant, removal may be difficult and may require surgical intervention. If the patient does not want to become pregnant, after the removal of the implant, she should ask her doctor about another contraceptive method. If the patient is planning a pregnancy, it is usually recommended to wait until the first natural menstrual period, which will make it easier to determine the expected date of delivery.
Like all medicines, Implanon NXT can cause side effects, although not everybody gets them. During the use of Implanon NXT, menstrual bleeding may occur irregularly. There may be slight spotting, not requiring the use of pads, or more heavy bleeding, which looks more like a scanty menstrual period, when pads are needed. Menstrual bleeding may also not occur at all. Irregular bleeding is not a sign of decreased contraceptive efficacy of Implanon NXT. It does not require any special actions. However, if bleeding is very heavy or prolonged, the doctor should be contacted. Serious side effects, such as cancer and thrombosis, are described in section 2. The patient should read this section for additional information and contact the doctor immediately if necessary. The following side effects have been reported:
Very common (may occur in more than 1 in 10 women) | Common (may occur in less than 1 in 10 women) | Uncommon (may occur in less than 1 in 100 women) |
Acne; headaches; weight gain; breast tenderness and pain; irregular menstrual bleeding; vaginal infections. | Hair loss; dizziness; depressive moods; emotional instability; nervousness; decreased libido; increased appetite; abdominal pain; nausea; bloating; painful menstrual bleeding; weight loss; flu-like symptoms; pain; fatigue; hot flashes; pain at the implant insertion site; local reactions at the implant insertion site; ovarian cysts. | Itching; itching in the genital area; rash; excessive hair growth; migraine; anxiety; insomnia; drowsiness; diarrhea; vomiting; constipation; urinary tract infections; discomfort in the vagina (e.g., vaginal discharge); breast enlargement; breast discharge; back pain; fever; fluid retention; painful or difficult urination; allergic reactions; throat inflammation and pain; cold; joint pain; muscle pain; musculoskeletal pain. |
In addition to the side effects listed above, increased blood pressure has been reported. Increased intracranial pressure (mild intracranial hypertension) with symptoms such as persistent headache, as well as nausea, vomiting, and changes in vision, including blurred vision, have been observed. Skin fattening has also been observed. Immediate medical attention should be sought if severe allergic reactions occur, such as facial, tongue, or throat swelling; difficulty swallowing; or hives and difficulty breathing. During the insertion and removal of Implanon NXT, bruising (in some cases severe), pain, swelling, or itching may occur, and in rare cases, infection may occur. A scar or abscess may form at the insertion site. After insertion, the patient may feel weakness. A feeling of numbness or tingling (or loss of sensation) may occur. It is possible for the implant to be expelled or to move, especially if it was not inserted correctly. Rarely, subcutaneous implants have been found in blood vessels, including the pulmonary artery, which may be associated with symptoms such as shortness of breath and (or) cough with or without bleeding. During the removal of the implant, surgical intervention may be necessary. In women using etonogestrel implants, cases of blood clots have been reported in the veins (so-called venous thrombosis) or arteries (so-called arterial thrombosis). A blood clot can block the veins in the legs (deep vein thrombosis), lungs (pulmonary embolism), or other organs. A blood clot can also block an artery, which can lead to a heart attack or stroke. If any side effects occur, including any side effects not listed in the leaflet, the doctor, pharmacist, or nurse should be consulted.
If any side effects occur, including any side effects not listed in this leaflet, the doctor, pharmacist, or nurse should be informed. Side effects can be reported directly to the Department of Adverse Reaction Monitoring of Medicinal Products, Medical Devices, and Biocidal Products: Al. Jerozolimskie 181C, 02-222 Warsaw, Tel.: +48 22 49 21 301, Fax: +48 22 49 21 309, website: https://smz.ezdrowie.gov.pl. Side effects can also be reported to the marketing authorization holder. By reporting side effects, more information can be collected on the safety of the medicine.
The medicine should be stored out of sight and reach of children. This medicine should not be used after the expiry date stated on the blister and carton after EXP. Store in the original packaging. Medicines should not be disposed of via wastewater or household waste. The pharmacist should be asked how to dispose of medicines that are no longer required. This will help protect the environment. There are no special precautions for storage.
Each applicator contains one subcutaneous implant with
Implanon NXT is a long-acting subcutaneous contraceptive. The single-use, innovative, easy-to-use applicator contains a non-radiopaque implant containing only progestogen. The implant is 4 cm long and 2 mm in diameter, white in color, and contains etonogestrel and barium sulfate. The applicator is specially designed to allow the doctor to insert the subcutaneous implant directly under the skin on the inner side of the arm (non-dominant hand). The subcutaneous implant should be inserted and removed only by a doctor familiar with the procedure. To ensure that the implant can be removed without problems, it should be inserted directly under the skin (see below in the leaflet). During the insertion and removal of the implant, local anesthesia should be used. The risk of complications is low if the following instructions are followed. The packaging sizes are: a cardboard box containing 1 blister, a cardboard box containing 5 blisters. Not all packaging sizes may be marketed.

The timing of the insertion of the implant depends on the previously used contraceptive method:
The implant should be inserted between the 1st and 5th day of the natural menstrual cycle, even if the woman is still bleeding (1st day of the cycle is the 1st day of menstrual bleeding). If the implant is inserted as recommended, there is no need to use additional contraceptive methods. If the timing of the insertion of the implant deviates from the recommended, the woman should be advised to use a barrier method for 7 days after the insertion. If sexual intercourse took place, it should be ensured that the patient is not pregnant.
To ensure effective action and uncomplicated removal of the Implanon NXT implant, it is essential to insert it correctly and carefully under the skin of the non-dominant arm, following the instructions.
Both the healthcare provider and the patient should be able to palpate the implant after its insertion.
Insertion of the Implanon NXT implant should be performed under aseptic conditions and by a trained healthcare provider familiar with the procedure.
The Implanon NXT implant should only be inserted using the specially designed applicator.
To ensure that the implant is inserted just under the skin, the healthcare provider should position themselves to see the needle being inserted, observing the applicator from the side, not from above the arm.
The insertion site and the movement of the needle just under the skin will be clearly visible from the side.

The implant can be removed in aseptic conditions by a trained healthcare provider who is familiar with the removal technique.
Persons not experienced in the removal technique should consult the manufacturer for further information.
Before starting the removal procedure, the healthcare provider should assess the implant location.
The implant should be localized by palpation in the arm.

Localization and removal of a non-palpable implant:
In rare cases, implant migration has been reported;
usually, this is a minor migration relative to the original location (see also section 4.4 of the Summary of Product Characteristics),
but it may make detection of the original implant location by palpation impossible.
An implant inserted too deeply or migrated may not be palpable and therefore, as described below, imaging techniques may be required for its localization.
Before attempting to remove a non-palpable implant, it should always be localized first.
Since the implant is not radiopaque, suitable localization methods include two-dimensional X-ray and computed tomography (CT).
Ultrasound (USS) with a high-frequency linear probe (10 MHz or higher) or magnetic resonance imaging (MRI) can be used.
After localizing the implant in the arm, it should be removed by a healthcare provider experienced in removing deeply inserted implants and familiar with the arm's anatomy.
Consider using ultrasound during the implant removal procedure.
If the implant cannot be localized in the arm after multiple attempts, consider using imaging methods of the chest, as in extremely rare cases, implant migration to the pulmonary vessels has been reported.
If the implant is localized in the chest, its removal may require a surgical procedure or interventional methods;
consult a healthcare provider familiar with chest anatomy.
If these imaging methods fail to localize the implant, measure the etonogestrel level in the patient's blood.
Consult the manufacturer for further instructions.
Consult the manufacturer for further instructions.
After removing the previous implant, a new one can be inserted immediately, as described in section 7.2.
A new implant can be inserted in the same arm and often through the same incision used for removal of the previous implant,
provided that the incision is correctly located, i.e., 8-10 cm from the medial epicondyle of the humerus and 3-5 cm posteriorly (below) from the groove between the biceps and triceps muscles (see section 4.2 "How to Insert Implanon NXT" of the Summary of Product Characteristics).
