However the benefit of a salicylate-free diet remains a contentious issue. Asthma Adult asthmatics, particularly in their 3 rd or 4 th decade, are more prone to develop a salicylate intolerance than children. Initially, an intense rhinitis with very watery and intermittent rhinorrhoea is experienced, and this is followed after a few months by chonic nasal congestion. Nasal polyposis may be found on examination in these patients. Asthma and occasionally conjunctivitis develops later on.
Symptoms occur up to an hour after ingestion of aspirin.
The asthma precipitated may be life threatening. Asthma and nasal polyposis associated with salicylates follows a protracted course even if aspirin is avoided thereafter. Paradoxically aspirin has been reported to relieve asthma in some patients. Children with asthma may also be affected by aspirin. Chronic Urticaria Aspirin has been found to be a trigger factor in a percentage of adult patients with chronic urticaria.
