Erectile dysfunction drug linked to higher glaucoma risk
A multinational study published in the British Journal of Ophthalmology suggests that long-term use of tadalafil, commonly used for erectile dysfunction and enlarged prostate, may increase the risk of glaucoma. Researchers recommend that patients on long-term daily doses undergo regular eye examinations.
