Popular erectile dysfunction drug linked to eye disease that can cause irreversible vision loss
Tadalafil users were 22% more likely to develop glaucoma, a study found, raising new questions about long-term Cialis use and eye pressure risks.
TL;DR
- 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.
