Over 1,000 plaintiffs are suing Merck & Co. in the Eastern District of Missouri over the birth control NuvaRing. The pharmaceutical company is charged with not warning women that the prescription medicine could cause blood clots and possible death. NuvaRing is different than other forms of birth control in that it dispenses hormones directly into the bloodstream which a plaintiffs’ pharmacology expert witness argues may cause “spikes” of hormones and lead to blood clots.
