Singulair is a drug used to treat asthma and allergies. Plaintiffs allege neuropsychiatric injuries, including tics, tremors, stuttering, obsessive-compulsive disorder, depression and/or suicidality as a result of taking Singulair. On January 4, 2022, the Supreme Court designated pending and future New Jersey state court litigation alleging injuries from use of Singulair as multicounty litigation and assigned it for centralized management to Atlantic County.
