- Bronchospasm, depression, decreased exercise tolerance, Raynaud’s phenomenon
- May increase triglyceride levels and insulin resistance, and decrease HDL levels
Warnings
Anesthesia/surgery (myocardial depression); chronically administered beta-blocking therapy should not be routinely withdrawn prior to major surgery, however the impaired ability of the heart to respond to reflex adrenergic stimuli may augment the risks of general anesthesia and surgical procedures
Use caution in cerebrovascular insufficiency, well-compensated CHF, liver disease, renal impairment, peripheral vascular disease
Use caution in nonallergic bronchospasm; may block bronchodilation produced by endogenous or exogenous catecholamine stimulation of beta receptors
Beta-adrenergic blockade may prevent appearance of premonitory signs and symptoms (eg, tachycardia and blood pressure changes) of acute hypoglycemia; this is especially important with labile diabetics; beta-blockade also reduces release of insulin in response to hyperglycemia; dose adjustment of antidiabetic drugs may be necessary
