Across all clinical studies with any tadalafil dose, changes in color vision were rare (<0.1% of patients).
Color Changes in Vision
Across all studies with any tadalafil dose, reports of changes in color vision were rare (<0.1% of patients).1
Single oral doses of phosphodiesterase (PDE) inhibitors have demonstrated transient dose-related impairment of color discrimination (blue/green), using the Farnsworth-Munsell 100-hue test, with peak effects near the time of peak plasma levels. This finding is consistent with the inhibition of PDE6, which is involved in phototransduction in the retina.1
