Copper IUD or Hormonal IUD: Which Is Better For You?

Birth control has been popular in the modern times. The intrauterine device (IUD) is one of the most commonly used forms of birth control. It is described as a small, T-shaped and flexible device which is inserted into woman’s uterus to prevent her from getting pregnant. Currently in the United States, there are two types of IUD available: the copper IUD and the hormonal IUD. There are about 2 percent of women in the United States who currently use IUD as their form of birth control, according to medical journals. To have a better understanding on which type of IUD is better for you, this article will discuss the characteristics of each type of IUD.

Copper IUD or ParaGuard

It is the most commonly used type of IUD. Copper wire is wound around the stem of the T-shape. This type of IUD works for as long as 12 years and is 99 percent effective if it is used properly. Copper IUDs prevent sperm from being able to go into the egg by immobilizing the sperm on the way to the fallopian tubes. If an egg does become fertilized, implantation on the wall of the uterus is prevented because copper changes the lining of the uterus. Side effects with this IUD include but are not limited to: anemia, backache, pain during sex, menstrual cramps, allergic reaction, vaginal infection, vaginal discharge, faintness or pain. It can also cause irregular bleeding throughout the cycle and heavier, more painful menstrual periods.

Hormonal IUD or Mirena

The hormonal IUD produces a small amount of progestin or similar hormone directly into the uterus. It works for five years and is believed to be 99.9 percent effective. Mirena can be used to treat excessively heavy menstrual bleeding. Heavy menstrual bleeding should be investigated by a doctor prior to insertion. It is a T-shaped plastic frame that releases progestin which thickens the cervical mucus to prevent sperm from reaching or fertilizing an egg. Mirena also thins the lining of the uterus and partially suppresses ovulation. Mirena side-effects include cramping, decreased sex drive, nausea, stomach pain, vomiting, irregular menstrual cycle, and skin problems or changes, such as acne.

If you are a woman who is inserted with Mirena IUD and who experienced these medical conditions, you need to contact your healthcare provider as soon as possible. The Food and Drug Administration has already released warning to Bayer, manufacturer of Mirena IUD, due to its over-advertisement but failed to disclose the product’s potential adverse side effects.
