Beta Blockers and Dry Eye: Why Beta Blockers Like Metoprolol Can Cause Dry Eye
Share
Dry eye is a side effect of many 21st century medicines including beta blockers such as metoprolol. Beta blockers are one of the largest categories of prescribed drugs in the U.S. and are a prime example of a drug that can cause dry eyes.
Beta blockers are a common treatment for hypertension, arrhythmias, and heart disease. They work by blocking β-adrenergic receptors, which slows the heart and lowers blood pressure.
However, these receptors are also found in other tissues including the eye’s lacrimal and meibomian glands. Suppression of those receptors reduces tear production and can alter tear composition.1
- Metoprolol, a cardioselective β1‑blocker, is the most prescribed in its class. In 2022, there were 65 million metoprolol prescriptions in the U.S., representing over 80% of all selective beta blocker use.2
- Among adults aged 60–79, over 22% are on beta blockers, per CDC data.
Special Risk Group: Menopausal Women
Considering many menopausal women are on antihypertensives like metoprolol, their combined medication and hormonal risk factors significantly increase likelihood of dry eye.
Hypertension affects nearly 50% of women over age 60, making it one of the most common chronic conditions in postmenopausal women. According to the CDC, approximately 58 million women in the U.S. have high blood pressure, and the likelihood increases sharply with age and menopause.
As a result, millions of women in midlife and beyond are prescribed antihypertensive medications, including beta blockers like metoprolol, to manage their heart health. In fact, women are more likely than men to be prescribed beta blockers for heart failure with preserved ejection fraction (HFpEF), a condition that disproportionately affects postmenopausal women.
This convergence of cardiovascular treatment and hormonal vulnerability creates a perfect storm for dry eye syndrome - a side effect often under-recognized but deeply impactful on quality of life.
Notably, hormonal changes during menopause, especially the drop in estrogen, are linked to both increased blood pressure and higher cardiovascular risk. This leads to many women seeking Hormone Replacement Therapy (HRT) which can exacerbate dry eye symptoms.
Menopause also causes a dramatic reduction in androgens which has been linked by the DEWS II working group paper (Sex, Hormones, and Gender) to meibomian gland dysfunction and dry eye.
Relieving Dry Eye from Beta Blockers
Managing dry eye involves eye hygiene, tear support, and lifestyle changes. Here's a multi-pronged protocol:
1. Gentle Lid Cleansing (“Peeqing Eyelids”)
- Use diluted tea tree oil (e.g. Peeq Pro Foaming Eyelid and Facial Cleanser or EyeEco Tea Tree Oil Cleanser) or hypochlorous acid eyelid wipes (e.g., Optase Protect Spray, TTO Wipes, or Pure&Clean HOCl products) to reduce lid margin microbes, controlling blepharitis and meibomian gland blockage.
- Perform daily – morning and evening – with light massage to express oil.
2. Warm Compresses
- Heat promotes meibomian gland function.
- Apply a 40°C (≈104-108°F) warm towel or commercial compress (e.g., Peeq Pro Warm Compress) for 5-10 minutes, followed by gentle lid massage.
3. Omega‑3 Fish Oil Supplementation (particularly post-menopausal women)
- Long-chain omega‑3s (EPA/DHA) can support tear film quality.
- Take 2,000 mg EPA/DHA daily.
4. Artificial Tears and Ointments
- Use preservative-free artificial tears (hyaluronate-based) throughout the day.
- Seal in moisture at night with lubricating ointment (petrolatum-based).
5. Environmental and Behavioral Adjustments
- Use a humidifier, avoid direct fans or AC drafts
- Blink consciously when on screens; consider moisture chamber glasses
- Drink water regularly to stay hydrated
- Adjust your work station appropriately
- Follow the 20/20/20 Rule
Final Thoughts
Beta blockers, especially metoprolol, are foundational medications for many—but their effect on tear production can cause persistent dry eye. That's especially true for menopausal women, particularly those on HRT.
The good news? A layered treatment strategy combining eyelid hygiene, warm compresses, omega‑3 supplements, and targeted eye drops can significantly relieve symptoms – without needing to change your essential heart medication.
And as always, be sure to communicate with your eye doctor about your medication and concerns.
