Clinical Update
Phosphodiesterase-5 Inhibitors Possibly Associated With Vision Loss July 11, 2005
The Food and Drug Administration (FDA) announced new labeling for sildenafil (Viagra®),
tadalafil (Cialis®), and vardenafil (Levitra®). The updated package inserts note rare cases of
sudden vision loss attributed to nonarteritic ischemic optic neuropathy (NAION) reported from
postmarketing surveillance. NAION is a condition where blood flow is blocked to the optic
nerve. NAION is more common in persons with heart disease, diabetes, hypertension, those who
smoke, are >50 years of age, or who have certain eye problems. Vision loss in one eye has been
reported in some men after taking these products. It is not known if sildenafil, tadalafil, or
vardenafil are directly the cause of this condition or if other related factors are responsible.
Patients taking a PDE5 inhibitor and who may experience vision loss should stop taking the
product and notify a healthcare provider immediately. Additional information can be found on
the following FDA website:
