Warnings

Caution in patients with diabetes mellitus (monitor glucose closely), glaucoma, hepatic/renal impairment, thyroid dysfunction
Some MAOIs have contributed to hypoglycemic episodes in diabetic patients receiving insulin or other blood-glucose-lowering agents; monitor blood glucose in patients receiving both this drug and blood-glucose-lowering agents; a reduction of the dosage of such agents may be necessary
Seizures reported with therapy withdrawal after abuse, and with overdose; patients with history or at risk for seizures should be monitored accordingly
Drug may worsen psychosis in patients with bipolar disorder
Therapy may aggravate coexisting symptoms in depression, such as anxiety and agitation
Although excretion of this drug is rapid, inhibition of MAO may persist up to 10 days following discontinuation; this should be taken into account when considering use of potential interacting substances or consumption of tyramine-rich food or beverages or when interpreting adverse reactions observed after discontinuation; care should be taken to differentiate symptoms of persistent MAO inhibition from withdrawal symptoms
Activation of mania/hypomania may be precipitated by antidepressant treatment in patients with bipolar disorder; screen patients prior to treatment, prior to initiating treatment, screen patients for any personal or family history of bipolar disorder, mania, or hypomania
Hypotension and hypertension during anesthesia and perioperative care may occur; it is recommended that therapy be discontinued at least 10 days prior to elective surgery
