Seeing blue after the little blue pill: Visual disturbances in Viagra users

(Frontiers) Sildenafil, a common treatment for erectile dysfunction, is typically safe with limited side effects. However, a new study reports persistent visual side-effects, including light sensitivity and color vision impairment, in a group of first-time users who took the highest recommended dose. Fortunately, these symptoms cleared up within 21 days for all the patients and appear to be very rare. Due to this, the study cautions that first-time Viagra users should start with a low dose.
