Beta-blockers are known to commonly cause insomnia, in addition to clonidine, theophylline, certain antidepressants, decongestants, stimulants, and certain over-the-counter and herbal remedies. Because of this, a patient's full medication history should be reviewed.
Other clues to underlying medical disorders predisposing patients to insomnia may be offered by physical examination. For example, a careful head and neck examination is warranted if the patient complains of symptoms suggestive of sleep apnea. A neurologic examination should look for symptoms of restless legs syndrome, periodic limb movement disorder, and any other neurologic disorder.
