Recurrent epistaxis after treatment with tadalafil (Cialis)

A 66-year-old male presented to our department with recurrent epistaxis. On examination it was not possible to identify the source of the bleeding, despite various measures. The bleeding stopped spontaneously each time and advice on nose bleeds was given to the patient. During a consultation the patient volunteered that the trigger for the epistaxis appeared to have been energetic sexual activity. To enhance his sexual performance he had taken Viagra; however, on stopping the Viagra and changing to the newer drug Cialis, the episodes of epistaxis continued. We document what we believe to be the first case of epistaxis caused by Cialis.
