Finding an effective medication for patients with major depressive disorder is notoriously difficult, with 70% of patients failing to respond to the first drug prescribed and 30% not responding to the first four medications. Complicating matters, genetic mutations can increase psychotropic drug-related adverse events, including hospitalizations. A recent study indicates Myriad Genetics Inc.’s Genesight test can help minimize the risk of these negative events, with a reduction of nearly 40% in psychiatric-related hospitalizations and prescription of medications with significant gene-drug interactions.
