The symptoms associated with admission for gastrointestinal haemorrhage were studied in relation to the intake of non-steroidal, anti-inflammatory drugs (NSAIDs) within fourteen days prior to admission. In a prospective, two-year study we included only those with bleeding due to gastroduodenal ulcers or haemorrhagic erosive gastritis. In 94 patients with a median age of 74 years, NSAID use was stated in 54, but the symptoms in these subjects (degree of epigastric pain, nausea or heartburn) were no different from those without previous NSAID use. Correspondingly, no difference was seen as to the clinical course of the bleeding.
