To assess the relationship between nonsteroidal anti-inflammatory drugs (NSAIDs) and spontaneous epistaxis in adults over 50 years old, a case control study was carried out by using a record linkage database for the population of Tayside, Scotland, which included 319,465 people. The study group consisted of 326 patients who were hospitalized with epistaxis between May 1989 and December 1992, but who had not previously been hospitalized with this diagnosis. Six community controls and 4 hospital controls, matched for age and sex to each case, were used. Previous exposure to prescribed aspirin and other NSAIDs was investigated. There was a significant association between aspirin exposure and epistaxis when either community or hospital controls were used (p < .001). Patients who had aspirin prescriptions had a relative risk of hospital admission for epistaxis of between 2.17 and 2.75, depending on the control group used. No association between non-aspirin NSAIDs and epistaxis was evident with either control group.
