ABSTRACT
We aimed to study the prevalence of the side-effects of statins among Iranians patients admitted to a cardiac-specialized hospital and had taken statins prior to hospitalization. Data was collected between September 2007 and March 2008 and 200 patients were enrolled. A questionnaire was completed using the patients' records and by interviewing the patients. The mean age of the participants was 61.5 [SD 12.3] years and 63% were males. The most commonly used statins was atrovastatin [99% of the patients]. In all, 63.5% of the participants reported experiencing side-effects due to statins. The reported side-effects were respiratory [4%]] and gastrointestinal effect [18.5%], headache [16.5%], rash [0.5%] and allergic reactions [5%]; 9.5% reported muscle-related side-effects such as myalgia. Although, the clinical benefits outweigh the small risk of liver failure and myopathy, clinicians should be aware of the side-effects of statins
