Mounjaro Can Now Be Prescribed to Lower Heart Attack and Stroke Risk in Adults with Type 2 Diabetes

The approval is based on a trial showing Mounjaro's non-inferiority to Lilly's Trulicity in cardiovascular outcomes. Mounjaro is now indicated for heart protection in high-risk diabetes patients, potentially affecting prescribing and insurance coverage decisions.
