Extract
Sildenafil is used to treat erectile dysfunction, and prescription on the NHS is restricted. We are conducting a study of prescription event monitoring for sildenafil in England, the first phase of which investigates possible short term effects in a cohort of about 5000 users. In view of the interest in myocardial infarction as a possible short term side effect, we report on an analysis of selected cardiovascular events reported in the first phase.
KEY WORDS - sildenafil, prescription-event monitoring, erectile dysfunction, cardiovascular events
