Serious warning labels sought for 3 ED drugs
October 22, 2005
A consumer group is asking the government to add
the most serious of warnings to the labels of Viagra and other impotence
drugs, noting some users have gone blind.
Public Citizen, the consumer group petitioned the Food and Drug
Administration on Thursday to add black-box warnings to the labels
of Viagra, Cialis and Levitra, as
well as the hypertension drug Revatio, which is similar to Viagra.
A small number of people taking the impotence drugs have developed
NAION, or non-arteritic ischemic optic neuropathy, a loss of vision
that is frequently irreversible. The condition is considered one
of the most common causes of sudden vision loss in older people,
with anywhere from 1,000 to 6,000 cases a year. Risk factors include
diabetes and heart disease, which are also two of the leading causes
of impotence.
In July, the FDA
ordered less prominent warnings to be added to the labels of the
three impotence drugs. The warnings noted that some users had suffered
vision loss but cautioned that it was impossible to know if the
pills were to blame.
