Introduction
Millions of adults rely on over-the-counter (OTC) sleep aids to fall asleep faster and improve rest. While these medications are widely accessible and often considered safe, recent studies suggest a link between certain OTC sleep aids and increased risk of heart failure. This discovery has sparked concern among healthcare professionals and patients alike.
Understanding the potential risks, how these medications work, and safer alternatives can help protect your heart while still promoting quality sleep.

What Are OTC Sleep Aids?
OTC sleep aids are medications that can be purchased without a prescription, typically used to manage short-term insomnia or difficulty falling asleep. Common ingredients include:
- Diphenhydramine – an antihistamine often found in “night-time” formulas.
- Doxylamine – another sedating antihistamine used in sleep medications.
- Melatonin – a natural hormone supplement that regulates sleep-wake cycles.
While generally effective for temporary sleep disturbances, some of these ingredients, particularly sedating antihistamines, can impact cardiovascular health if used frequently or in high doses.
How OTC Sleep Aids May Affect the Heart
Recent research indicates that long-term or excessive use of certain OTC sleep medications can increase heart failure risk, especially among older adults or individuals with pre-existing heart conditions.
Key concerns include:
- Increased heart strain: Some antihistamines may elevate heart rate or blood pressure.
- Fluid retention: Certain ingredients can worsen fluid buildup, a common factor in heart failure.
- Interactions with other medications: OTC sleep aids can interfere with cardiovascular medications.
Who Is Most at Risk?
While anyone using OTC sleep aids should be cautious, risk is particularly elevated for:
- Individuals over 60 years old
- Those with a history of heart disease, high blood pressure, or kidney issues
- People taking multiple medications for chronic conditions
- Chronic users of sleep aids for more than 2-4 weeks

Safer Alternatives to OTC Sleep Aids
You don’t have to compromise heart health for quality sleep. Safer strategies include:
- Sleep hygiene improvements – maintain a consistent sleep schedule, reduce screen time before bed, and create a dark, cool sleep environment.
- Cognitive Behavioral Therapy for Insomnia (CBT-I) – a non-drug therapy shown to improve sleep long-term.
- Natural supplements – melatonin or magnesium, under medical guidance, can be safer options.
- Relaxation techniques – deep breathing, meditation, or yoga before bedtime.
Tips for Safe Use if You Must Take OTC Sleep Aids
- Limit use to short-term or occasional insomnia
- Avoid combining multiple sedatives
- Always follow package directions
- Consult a doctor if you have heart disease, kidney problems, or high blood pressure
- Monitor for side effects like dizziness, swelling, or palpitations
Doctor Advice:
While OTC sleep aids provide temporary relief for sleepless nights, recent evidence highlights the potential risk of heart failure, particularly with prolonged use. Prioritizing safe alternatives, maintaining healthy sleep habits, and consulting healthcare professionals are essential for protecting both your sleep and your heart.
