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

Key Points:

• New research suggests that long-term use of tadalafil, a drug for erectile dysfunction and enlarged prostate symptoms, may increase the risk of glaucoma, a serious eye condition that can cause gradual vision loss.
• The study analyzed health records of nearly 74,000 men aged 40 and older and found that tadalafil users were 22% more likely to develop glaucoma and had higher risks of elevated eye pressure and primary open-angle glaucoma.
• Experts highlight that glaucoma often has no early symptoms and recommend comprehensive eye exams for people using tadalafil long-term, especially those with existing risk factors like family history or high eye pressure.
• The study was observational and cannot prove causation; researchers advise patients to continue tadalafil but suggest regular eye monitoring for those on long-term treatment.
• The drug manufacturer and study authors were contacted for comment, emphasizing the importance of further investigation and patient awareness.
