You have probably heard the qualifiers at the end of Viagra advertisements warning “seek immediate medical attention if you notice any sudden change in hearing”. While the risk of hearing loss has long been reported for those taking Viagra, prompting the FDA to require a warning label on the bottle in 2007, the actual data validating that risk has not been quantified until now.
A recent study of 11,525 men over the age of 40, performed at the University of Alabama-Birmingham, found a significant association between Viagra and permanent hearing loss for the first time. Men who used Viagra were more than twice as likely to report hearing loss than those who did not. Men who used Cialis or Levitra also reported a higher than normal incidence of hearing loss; however, the rate was not determined to statistically significant.
Dr. Gerald McGwin, the lead author in the study, suggests that increased blood flow associated with Viagra use may be the mechanism responsible for damage to the auditory system. He goes on to warn “it is prudent that patients using these medications be warned about the signs and symptoms of hearing impairment and be encouraged to seek immediate medical attention to potentially forestall permanent damage”.
