The Claim
Long-term melatonin use in adults diagnosed with insomnia is associated with a significantly higher incidence of heart failure over a five-year period, with an absolute risk difference of 1.9% and a hazard ratio of 1.89 compared to non-users, indicating potential cardiovascular risks.
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 for sleep over a long period might slightly increase your chance of developing heart failure compared to not taking it. This small but noticeable increase in risk means doctors should keep an eye on heart health when prescribing it for insomnia.
See the scientific wording
Long-term melatonin prescription use in adults diagnosed with insomnia is associated with a significantly higher incidence of heart failure over a five-year period, with an absolute risk difference of 1.9% and a hazard ratio of 1.89 compared to non-users. This finding indicates that chronic melatonin supplementation may carry cardiovascular risks that warrant clinical attention in patients managing sleep disorders.
What the research says
1 studyThis large study found that adults with insomnia who took melatonin long-term were nearly twice as likely to develop heart failure over five years compared to those who did not take it. The results suggest that long-term melatonin use might carry heart risks that doctors should consider.
