Generalized anxiety disorder (GAD), is characterized by unrealistic or excessive anxiety and worry about two or more life circumstances for at least six months.

B. Other features of GAD include insomnia, irritability, trembling, dry mouth, and a heightened startle reflex.

Pharmacologic causes of anxiety include salicylate intoxication, NSAI Ds antihistamine intoxication/withdrawal, phenylpropanolamine pseudo-ephedrine, psychotropics (akathisia), stimulants, selective serotonin reuptake inhibitors. Caffeine, cocaine, amphetamines, theophylline, beta-agonists, over-the-counter decongestants, steroids, and marijuana can cause anxiety.

A. Chemistry profile (glucose, calcium, phosphate), TSH.
