Paragard is an IUD (intrauterine device) implanted in the uterus to prevent pregnancy. The device is made by Cooper Surgical and received an FDA New Drug application approval in 1984. Among the three IUDs on the market - Mirena, Skyla and Liletta - Paragard is the only one that uses copper, not a hormone. Unfortunately, there have been thousands of reports of problems in women implanted with Paragard, including at least 15 deaths.

Bayer stopped selling its Essure birth control device in the U.S. late in 2018 due to thousands of reports from the public of complications.
