ADRs: hypoglycemia in vulnerable populations Contraindication: hepatic impairment, Pregnancy Catagory C, not approved in pediatrics. Caution in severe renal impairment and adrenal/pituitary impairment b/c these drugs may exert more glucose-lowering effects.

SSRIs inhibit reuptake of serotonin. SSRIs are 1st line for depression and anxiety (lLONG TERM). Benzodiazepines (xanax, valium) are 1st line for ACUTE symptoms. They bind to GABA receptors; increase the action and decrease excitability. SSRIs are much safer, will not cause dependence like benzo's. SSRIs are used for depression, anxiety, OCD, PTSD, panic disorders, and migraines.
