Common questions about Nexplanon implant (FAQ)
Q: How quickly does the Nexplanon implant start protecting against pregnancy after insertion?
A: The onset of contraceptive protection depends on the timing of insertion relative to your menstrual cycle. If the implant is inserted within the first five days of a menstrual period, official information indicates it provides protection when inserted immediately.
If it is inserted at any other time, the use of a non-hormonal backup method, such as a condom, may be recommended or necessary for the first seven days.
Q: Is the Nexplanon implant the same as Implanon, or is there a difference?
A: Nexplanon is described in official documentation as an updated, second-generation version of the original Implanon device. A key difference is that Nexplanon contains barium sulfate, making it radiopaque (visible on X-ray). This feature was added to improve the ability of healthcare providers to locate the implant after insertion.
Q: Does the Nexplanon implant ever stop my period completely?
A: Yes, changes to the menstrual bleeding pattern are a very common occurrence. According to official product information, one of the changes that may be experienced is having no bleeding at all during the time of the period, which is clinically known as amenorrhea.
Q: How does the progestin hormone in Nexplanon differ from the hormones in combination birth control pills?
A: The Nexplanon implant is a progestin-only contraceptive, meaning it contains a single synthetic hormone: etonogestrel. Combination birth control pills, however, contain two types of hormones: a progestin and an estrogen hormone. This distinction defines the pharmacological class of the implant.
Q: Does the Nexplanon implant protect against sexually transmitted infections (STIs)?
A: No. Official medical sources clearly state that the Nexplanon implant, like all hormonal contraceptive methods, does not provide protection against HIV/AIDS or any other sexually transmitted infections (STIs).
Q: How soon can a person become pregnant after the Nexplanon implant is removed?
A: The return to fertility is generally prompt after the implant is removed by a healthcare professional. Official information suggests a person may become pregnant shortly after removal, as early as the first week the implant is taken out.
Q: Does the implant affect a person's future fertility after it is removed?
A: The Nexplanon implant is considered immediately reversible upon removal. Official medical data indicates there is no evidence that its prior use affects a person's ability to become pregnant in the future.
Q: Is the implant always visible or easily felt under the skin after insertion?
A: Immediately after the insertion procedure, the healthcare professional must check that the implant is in the arm by palpation (feeling for it). If the implant cannot be felt upon immediate check, additional tests may be required to confirm and locate its position.
Q: Is there any risk to the fetus if the implant is accidentally inserted during an existing pregnancy?
A: Use of the implant is contraindicated, meaning it must not be used, during a known or suspected pregnancy. Regulatory documentation indicates that based on experience with other hormonal contraceptives, the implant is not likely to cause birth defects.
Q: How does a person check or confirm that the Nexplanon implant is still correctly in place?
A: The presence of the implant is typically confirmed by feeling for it in the arm. If a person cannot feel the implant at any time, it is important to contact a healthcare professional immediately for confirmation. The implant’s radiopacity allows for confirmation via certain imaging tools.
Q: Is it necessary to use a backup birth control method immediately after the implant is inserted?
A: A backup, non-hormonal method is required only in certain circumstances. If insertion of the implant occurs after the fifth day of the menstrual cycle, a backup method is recommended for the first seven days where applicable.
Q: Can the implant interfere with medical imaging like X-rays or MRI scans?
A: The implant contains barium sulfate, a feature that makes it radiopaque, allowing it to be seen clearly on imaging such as X-ray or CT scans. Official labeling includes specific information regarding the safety of the device during MRI procedures.
Q: Are there any specific concerns for people who have a history of migraine headaches and want to use Nexplanon?
A: Headache is listed as a very common side effect in the regulatory documentation for the implant. Official information indicates that a history of headaches, including migraines, is a topic that should be discussed with a healthcare professional.
Q: What should a person do if they cannot feel the Nexplanon implant in their arm?
A: If a person is unable to feel the implant in their arm at any time, it is recommended to contact a healthcare professional immediately. The use of a non-hormonal backup method may be necessary until its presence is confirmed by a healthcare provider.
Q: Can the implant cause or be related to symptoms of a severe allergic reaction?
A: Yes, official labeling includes warnings that a person should seek immediate medical attention if they experience symptoms of a severe allergic reaction. These symptoms may include a swollen face, tongue, or throat, or trouble breathing or swallowing.
Q: What are the potential risks if the implant is inserted incorrectly or too deeply?
A: The procedure is designed to be performed only by trained healthcare professionals. Official warnings note that insertion that is too deep may cause difficulty with locating and removing the implant, potentially leading to the need for surgery.
Q: Is it common to have significant bruising or swelling at the insertion site?
A: Yes, the insertion procedure can result in local effects at the site. Documentation states that common complications at the insertion site may include pain, swelling, or bruising (hematoma) following the procedure.
Q: How is the implant removed, and is a local anesthetic always used?
A: The removal procedure must be performed by a healthcare professional. To remove the implant, the provider will first numb the area. Local anesthesia is typically used as part of the standard removal process before making a small incision to take the implant out.
Q: What should a patient know about the user card received after the implant is placed?
A: Official instructions indicate that patients receive a user card that serves as a vital record. This card records the exact insertion date, the final 3-year removal date, and the specific location (which arm) of the implant.
Q: Is the implant designed to prevent or reduce menstrual cramps?
A: The primary purpose and approval of the implant are for the prevention of pregnancy. However, the regulatory documentation lists dysmenorrhea (painful menstruation or cramps) as a Common side effect, indicating a potential effect on cramps.
Q: Does the implant affect the risk of ectopic pregnancy compared to using no contraception?
A: The overall risk of ectopic pregnancy (pregnancy outside the uterus) is very low for users because the implant is highly effective at preventing pregnancy. However, official warnings note that if a woman does become pregnant while using the implant, the likelihood of that pregnancy being ectopic is increased.
Q: Why is the Nexplanon implant typically inserted in the non-dominant upper arm?
A: Official administration instructions specify that the insertion site is the inner side of the non-dominant upper arm. This particular site is chosen as a procedural safeguard to help minimize the potential for injury to nerves or major blood vessels in the arm.
Q: What are the signs that a person should contact a healthcare provider urgently while using the implant?
A: It is advised to seek immediate medical attention for urgent symptoms described in the official warnings. These include signs of a severe allergic reaction, a sudden severe headache, or signs of a blood clot, such as unexplained pain or swelling in the lower leg or severe chest pain.
Q: Can the implant be inserted immediately after a miscarriage or abortion?
A: The timing for insertion varies depending on the circumstances. The implant can be inserted immediately after a first-trimester abortion or miscarriage. For a second-trimester abortion or miscarriage, official guidance recommends waiting until four weeks after the procedure.
