The Claim
Long-term melatonin prescription use in adults with insomnia is associated with a significantly increased risk of heart failure-related hospitalizations, demonstrating a three-fold higher hazard ratio compared to matched controls without melatonin exposure.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Taking melatonin long-term to help with sleep might actually raise the risk of being hospitalized for heart failure. Research suggests people who use it over a long period face about three times the risk of serious heart problems compared to those who don't take it.
See the scientific wording
Adults with insomnia who maintain long-term melatonin prescriptions experience a substantially increased rate of heart failure-related hospitalizations, showing a three-fold higher hazard ratio (3.44) compared to matched controls without melatonin exposure. This suggests that prolonged melatonin use in this population may be linked to more severe cardiovascular events requiring acute medical intervention.
What the research says
1 studyThe study tracked secondary endpoints using stratified Cox models on a propensity-matched cohort of over 130,000 patients. The reported hazard ratio of 3.44 and absolute rates of 19.0% versus 6.6% provide direct statistical evidence supporting the claim of a strong association between long-term melatonin use and increased heart failure hospitalizations.
