title: How disturbing are side effects of beta blockers.
abstract: Drug side effects are notoriously difficult to evaluate accurately. In this particular context there are further problems arising from the exclusion of many patients in some of the few published series of populations exposed to beta-blocking drugs. In some of these same series, placebo side effects appear to affect almost as many patients as the active drug. However, detailed breakdown of these side effects show significant differences in the actual complaints made by patients of each group. Apart from the well known major complications of beta-blocking drugs, the lesser but still disturbing ones to mention include generalized fatigue, muscle weakness, cold extremities, nightmares and impotence. A change of beta-blocking preparation or else lowering the dosage often ameliorates these problems.
