What is Jadelle Implant?
Jadelle is a reversible long acting contraceptive implant that is composed of two flexible silicone-based rod implants, each measuring 43mm long and 2.5mm wide. Each Jadelle implant contains 75mg levonorgestrel as active ingredient. Excipients are: polydimethyl siloxane, anhydrous colloidal silica.
Jadelle is a long acting progestin only contraceptive preparation that can last for up to 5 years. What this means is that, Jadelle can prevent pregnancy for upto 5 years once it has been inserted. Jadelle is normally inserted underneath the skin. Jadelle is manufactured by Bayer Oy Company.
The Jadelle implants comes as two rubber like rods that are thin and flexible and can be inserted in the outpatient clinic by the inner aspect of the arm (the part that touches the skin of the chest). It is normally inserted in the arm that you may do not use often. If you are a right handed woman, then Jadelle will be inserted in the left arm and if you are left handed, then Jadelle is inserted in the right arm. This is to enable you use your most preferred arm very well. It doesnt mean that Jadelle paralyses arms but just for comfort while doing any task.
Mechanism of Action of Jadelle implant
Jadelle contains a chemical substance called a hormone. The name of this hormone is called Levonorgestrel. This hormone is the most active substance in Jadelle, hence it is called the Active ingredient. After insertion of Jadelle implant, the levonorgestrel starts to be released continuously in small amount into the body. The released levonorgestrel causes the mucus of the cervix to become thickened, making it difficult for the spermatozoa to penetrate and get to the ovum. You are to note that it thickens the mucus, on order to make it difficult to penetrate. Sometimes, the mucus can be penetrated and pregnancy may still occur even while using Jadelle (that is why it is always said that there is no contraceptive method that is 100% protective except abstinence). However, the chance of this happening is very rare; hence you should not be worried. Another mechanism through which Jadelle implant works is by inhibition of the release of the ovum (human egg) from the Ovary.
Effectiveness of Jadelle impants
As earlier stated, jadelle can prevent pregnancy for up to 5 years effectively with a failure rate of less than 1% every year. This means that out of 100 women that use jadelle, less than 1 of them may become pregnant. However, it is very effective and can prevent pregnancy to a very large extend. After 5 years, the effectiveness of jadelle implant reduces and pregnancy may occur. It does not mean that once it has been inserted, one cannot remove it again. If you change your mind to become pregnant or may want to change another contraception method, you are free to remove the jadelle any time after without actually waiting for 5 years.
For women weighing greater than 60kg, the effectiveness of the Jadelle may not be up to 5 years because of their body weight; the more the weight, the less the effectiveness of the jadelle implant.
Use of Jadelle Implant
Jadelle is primarily used for prevention of pregnancy and it is a very good method of family planning especially for long term birth control. However, it does not protect from sexually transmitted infections such as Gonorrhea or syphilis, vaginal infections, or even HIV/AIDS.
Before using this contraceptive implant, it is good you discuss with your medical doctor because it has risk and benefits and your doctor would advise you as to whether it is good for you or not.
Jadelle is one among many types of contraceptive methods and can be substituted by others if it is not suitable for use by you.
The insertion of Jadelle is easier than its removal and some medical doctors have more experience in insertion and removal of Jadelle than others.
Removal of Jadelle may be more painful and difficult than the insertion and may leave a scar after removal (a risk that can be avoided by using other contraceptive methods other than impalnts).
Use of Jadelle after giving birth
If Jadelle is inserted within 3 weeks of delivery, then it is unlikely that you may be pregnant; hence there would be no need for other contraceptive precautions. But if you are using it after 3 weeks of delivery, then a pregnancy test would have to be done to confirm you are not pregnant before inserting the implant and after insertion, non-hormonal contraceptive methods such as use of condoms or cervical cap must be done for a minimum of 7 days to allow for adequate distribution and action of Jadelle to occur first before the non-hormonal method is stopped.
Breastfeeding mothers may still use Jadelle but should first discuss with their doctors first. It is excreted in breast milk but there is no evidence of any unwanted effect on breast fed babies.
Using Jadelle implant after Miscarriage or Abortion
Immediately after miscarriage or abortion, the implant can be inserted.
Procedure on Insertion of Jadelle
The insertion of tis implant should be done by a health care professional who knows the procedure. It is implanted within 7 days from the start of the menstrual flow (within the first 7 days when bleeding starts) to ensure the woman is not pregnant.
It is inserted using a local anaesthetic agent such as lidocaine to help reduce the pain during insertion. The implants are inserted just underneath the skin which makes it easier for removal. The deeper it is inserted, the more difficult it is to remove it.
