            Warnings

            Black Box Warnings

            In short-term studies, antidepressants increased the risk of suicidal thinking and behavior in children, adolescents, and young adults (<24 yr of age) taking antidepressants for major depressive disorders and other psychiatric illnesses

            This increase was not seen in patients aged >24 years; a slight decrease in suicidal thinking was seen in adults >65 years

            In children and young adults, risks must be weighed against the benefits of taking antidepressants

            Patients should be monitored closely for changes in behavior, clinical worsening, and suicidal tendencies; this should be done during initial 1-2 months of therapy and dosage adjustments

            The patient’s family should communicate any abrupt changes in behavior to the healthcare provider

            Worsening behavior and suicidal tendencies that are not part of the presenting symptoms may require discontinuation of therapy

            This drug is not approved for use in pediatric patients

            Contraindications

            Hypersensitivity

            Severe cardiovascular disorders

            Narrow angle glaucoma

            Within 14 days of MAO inhibitors may cause serotonin syndrome

            Any drugs or conditions that prolong QT interval

            Acute recovery post-MI

            Cautions

            Caution in BPH, urinary/GI retention, increased IOP, hyperthyroidism, open-angle glaucoma, seizure disorder, brain tumor, respiratory impairment

            Clinical worsening & suicide ideation may occur despite medication in adolescents & young adults (18-24 years)

            Risk of anticholinergic side-effects

            May cause sedation (may impair physical and mental abilities), orthostatic hypotension, and anticholinergic effects

            Pregnancy & Lactation

            Pregnancy Category: B

            Lactation: avoid during breastfeeding

            Pregnancy Categories

            A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.

            B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.

            C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.

            D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.

            X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.

            NA: Information not available.
