Brief description/objective

Five patients with adverse reactions to peak flow monitoring are presented: 2 patients had herniation of abdominal content, while the others presented with vasovagal syncope, minor depression and neurotic preoccupation with peak flow values, respectively. As a result, 3 of the 5 patients became noncompliant. For nonpsychological somatic adverse reactions, we calculated an incidence of 1.1 cases/1,000 patients started on peak flow monitoring. Adverse reactions with a psychological background may be more frequent. Clinicians should bear in mind that patients noncompliant with peak flow monitoring may have discontinued because of adverse reactions.
