Popular erectile dysfunction drug linked to eye disease that can cause irreversible vision loss

New research indicates that tadalafil, a drug used for erectile dysfunction and enlarged prostate symptoms, may be associated with an increased risk of glaucoma. The study found that men using tadalafil were more likely to develop glaucoma and experience elevated eye pressure. While the study highlights a link, it cannot prove causation, and experts advise against discontinuing the medication without consulting a doctor, recommending regular eye monitoring for long-term users.

• A study analyzed health records of nearly 74,000 men aged 40+ with lower urinary tract symptoms.
• Researchers examined the association between long-term tadalafil use and the risk of glaucoma.
• Men using tadalafil were 22% more likely to develop glaucoma, 32% more likely to develop high eye pressure, and 33% more likely to develop primary open-angle glaucoma.
• Glaucoma can cause gradual vision loss, often without early symptoms, and is best detected through comprehensive eye evaluations.
• The study was observational, meaning it found a link but could not prove tadalafil caused glaucoma.
• Researchers suggest that patients using tadalafil long-term, especially those with existing risk factors, might benefit from regular eye monitoring.
• The findings do not mean people should stop taking tadalafil.
