Intrauterine devices (IUDs) are T-shaped tools that can be placed into your uterus to avoid pregnancy. There are five FDA-approved brands of IUDs readily available in the United States: Kyleena, Liletta, Mirena, ParaGard, as well as Skyla.
While IUDs as a contraception option are thought about among the most effective, there are differences among your options, which require to be taken into consideration. Knowing more about them can help you decide whether an IUD is right for you and also, if so, which one.
Overall, there are several similarities between every one of the IUDs you can choose from. From the widest perspective, all of the IUDs accepted by the UNITED STATE Food and Drug Administration (FDA) are considered to be very effective methods of contraception. 1 They can be utilized on their own and also are reversible, suggesting that you can become pregnant when you are quitting making use of the IUD.
All IUDs should be placed into your uterus and gotten rid of by a medical professional. Relying on the brand name, they can be kept in area for anywhere from three to one decade.
IUDs generally have a low risk of side effects and negative occasions. There is a threat of expulsion (the IUD falling out). If this happens, you can get expectant until you begin to utilize an additional technique of birth control or have your IUD replaced. There is additionally a little danger of pelvic infection or a uterine tear, although these difficulties are unusual.2.
Clinical evidence shows that because of the place of the IUD, there is a slightly raised danger of an ectopic (tubal) maternity. Ectopic pregnancies are non-viable and also potentially life-threatening if the dental implanted egg creates the rupture of the fallopian tube.
The main distinction among the IUDs is that all but one launch the hormone levonorgestrel (a progestin) to avoid pregnancy. On the other hand, ParaGard, which is hormone-free, works since it is constructed from copper.
Marketed under the brand names Mirena, Liletta, Skyla, as well as Kyleena, these IUDs are composed of a polydimethylsiloxane sleeve which contains levonorgestrel, a progestin hormonal agent, on the stem.
Levonorgestrel stops maternity by thickening the cervical mucous, thinning the uterine wall surface, and also impairing the binding of sperm to the egg. Not just is fertilization unlikely, the probabilities of implantation are low even if fertilizing occurs.
The hormone dosages differ for every of the levonorgestrel IUDs. They each at first release a higher dose of the hormonal agent, which lowers in time. As the dosage of hormone released declines, the tool remains effective in stopping maternity throughout suggested usage.
Each brand name is recommended for a defined period, varying from three to 5 years.
- Mirena originally launches 20 mcg of levonorgestrel each day and also is FDA-approved for as much as five years.
- Liletta initially releases 19.5 mcg each day of levonorgestrel and is accepted for four years of use.
- Skyla originally releases 14 mcg of levonorgestrel each day as well as can be made use of for approximately three years.
- Kyleena originally releases 17.5 mcg of levonorgestrel each day. It can continue to be in position for five years.
Since these 4 IUDs have progestin, you may experience a decline in your menstrual flow. For instance, you might find for the initial few months and afterwards have lighter as well as much shorter durations. Your duration might additionally quit altogether, which is considered secure.
Opposite side effects might include headaches, nausea, bust tenderness, clinical depression, lowered libido, loss of hair, as well as ovarian cysts.
Copper IUD (ParaGard)
ParaGard is the only hormone-free IUD accepted by the FDA. It is composed of polyethene covered with copper wire and has a completely various mechanism of activity.
ParaGard avoids pregnancy by setting off an inflammatory reaction to the copper which damages the egg, impairs the movement and practicality of sperm, and diminishes the capacity of an egg to implant even if it is fed.
Of all the IUDs, the ParaGard can be made use of for the lengthiest duration, which depends on ten years.
Because the copper IUD is hormone-free, it must not modify the timing of your menstruation. Nevertheless, it may create heavy periods with more cramping or neck and back pain than usual, specifically in the first numerous menstruations after its placement.4.
