Abstract
Incidence/prevalence NSAIDs are widely used. Almost 10% of people in the Netherlands had used a non-aspirin NSAID in 1987; the overall use was 11 defined daily doses (see box) per 1000 persons a day.1 In Australia in 1994, overall use was 35 defined daily doses per 1000 persons a day, with 36% of the people receiving NSAIDs for osteoarthritis, 42% for sprain and strain or low back pain, and 4% for rheumatoid arthritis; 35% were aged over 60 years.2
