Withdrawal Of IUDs In United States

With the discovery that the addition of copper increased the effectiveness of the IUD, the devices could be made smaller to decrease their side effects. In 1974 and 1978, the Copper 7 and Tatum T were released. The timing was unfortunate, however, since the Dalkon Shield had just been taken off the market and litigation was on the rise. Although the Dalkon Shield was the only IUD implicated, all other IUDs were hurt by the negative publicity. By 1986, every IUD in the United States (Lippes Loop, Saf-T-Coil, Copper 7, Tatum T), except for Progestasert, was withdrawn from the market for economic reasons. The cost of defense for so much litigation, largely unwarranted, proved to be too expensive for these IUD manufacturers. From 1986 to 1988, the Progestasert was the only IUD available in the United States. It was not until 1988 that GynoPharma released a new copper IUD, the T 380A IUD (ParaGard).
