"Study Raises Heart Failure Concerns Over Melatonin Use; Experts Urge Caution"

New research indicates that long-term use of melatonin may elevate the risk of heart failure, prompting experts to advise caution for individuals with insomnia.

• A study reviewed electronic health records of tens of thousands of adults with insomnia, revealing that long-term melatonin users face a heightened risk of heart failure.
• Those who took prescribed melatonin for over a year had a significantly increased chance of developing heart failure compared to nonusers over a five-year period.
• The findings, announced by the American Heart Association, emphasize the need for further investigation into the safety of melatonin, an over-the-counter drug often used to regulate the circadian rhythm.
