Development and studies of the Mirena Coil began in the 1970s. Schering Health distributes Mirena outside the United States, while Berlex distributes it inside the United States. Both companies have worked with the Population Council, a that has worked with other contraceptive manufacturers (including Wyeth, maker of Norplant).
Mirena was first marketed commercially in Finland in 1990, but not approved by the U.S. Food and Drug Administration until 2000. It is intended to initially release 20 micrograms of levonorgestral per day and may be used for five years. Sound familiar?
Norplant is a form of birth control was first approved in 1983 in Finland. The original Norplant consisted of a set of six small (2.4 mm x 34 mm) silicone capsules, each filled with 36 mg of levonorgestrel (a progestin used in many birth control pills) implanted subdermally in the upper arm and effective for five years. The original (6 capsule) Norplant's production has been phased out; USAID's contract ran until December 2006.
The original (6 capsule) Norplant was approved by the FDA in 1990 and marketed in the United States in 1991 by Wyeth Pharmaceuticals. Norplant distribution in the United States ended in 2002; limited supplies still remained in the U.S. until 2004. Norplant was withdrawn from the UK market in 1999.
After three months of using Norplant, women will need to schedule a follow-up appointment to monitor blood pressure and discuss any concerns. Side effects may include irregular menstrual periods for the first approximately three months, including periods lasting longer than normal, bleeding or spotting between periods, heavy bleeding, or going with no period for the mentioned period of time. Common side effects include weight gain, nervousness, anxiety, nausea, vomiting, mastalgia, dizziness, dermatitis/rash, hirsutism, scalp-hair loss, headache, depression, and acne. Sometimes, pain, itching or infection at the site of the implant will occur. Ovarian cysts may also occur, but usually do not require treatment, although they can cause pain even if benign.
Norplant discontinued in the United States
By 1996, more than 50,000 women had filed lawsuits, including 70 class actions, against Wyeth and/or its subsidiaries, or doctors who prescribed Norplant. Wyeth never lost a Norplant lawsuit.
On August 26, 1999, after winning 3 jury verdicts, 20 pretrial summary judgments and the dismissal of 14,000 claims, Wyeth offered out-of-court cash settlements of $1,500 each to about 36,000 women who contended that they had not been adequately warned about possible side effects of Norplant such as irregular menstrual bleeding, headaches, nausea and depression. Wyeth said that most of the plaintiffs experienced routine side effects described in Norplant's labeling information. About 32,000 women accepted the out-of-court $1,500 settlements.
At least they warned the user of these side effects and the no longer offer Norplant in the US
