The Orange Book lists 4 patents for Belsomra tablets: the compound patent runs to November 20, 2029, and the last listed entry to May 29, 2033. A patent or exclusivity date is not the date a generic goes on sale: court cases and settlements move it either way.

What do FAERS reports show for suvorexant?

The FDA Adverse Event Reporting System holds 12,888 reports that list suvorexant among the medicines taken, through July 30, 2026, each a report of something that happened, not proof the medicine caused it; 696 are coded as a death and 2,028 as a hospital stay. Counts follow how widely a medicine is used and watched, and they are not a measure of how risky it is. Reports rose sharply in 2016 (2,499, against a median of 714 a year): FAERS counts follow reporting, which news, litigation and label changes can drive, not how often a reaction happens.
