Abstract
BACKGROUND: The published literature is lacking in data on the frequency and severity of medication side effects in the general asthma population. METHODS: Questionnaires regarding asthma severity, treatment, and medication side effects were answered by 1230 and 604 pediatric and adult asthmatics, respectively, 70% to 75% of whom were consulting a specialist. RESULTS: Most respondents (58%-79%) reported unwanted side effects from their bronchodilators, most of which had been racemic albuterol prescribed in either generic or name brand form. Side effects were most common in nebulizer users of all ages and in pediatric patients using oral medications. The most common troublesome side effects were jitteriness (58%), restlessness (57%), tachycardia (56%) and cough (56%) in the pediatric patients and tachycardia (64%), jitteriness (60%), shaky hands (43%), and restlessness (42%) in the adult respondents. Most patients had spoken to their physicians about their side effects, and the most common response was to change brands within the same class of medication, adjust the dose, or advise the patients to tolerate the side effects because the medications were necessary and side effects were to be expected. Fewer than 4% of all respondents viewed their physicians as "caring/sympathetic/willing to listen/discuss their bronchodilator side effects." Twenty-five to thirty percent of patients had reduced their bronchodilator dose on their own, and 14% to 24% had skipped doses to avoid unwanted side effects. Hospitalizations were infrequent and were most commonly seen in the nebulizer users, who were also rated by their physicians as more likely to have severe asthma. Other markers of asthma control (such as emergency room visits, unscheduled doctor visits, and being sent home from school/work for asthma symptoms) were not only common in the nebulizer user group but also in children who used oral medications. This group was more likely to have been classified by their physicians as having mild asthma, suggesting perhaps a need for more intensive asthma education in this group. CONCLUSION: Medication side effects are common in individuals with asthma and are most often ascribed by the patients to their bronchodilators. There is a need for new, rapid-acting bronchodilators with fewer side effects.
