(See Pediatric Use under Cautions and also see Advice to Patients.)

Use with caution and under direction of a clinician in patients with thyroid disease (e.g., hyperthyroidism), heart disease (including angina), hypertension, advanced arteriosclerotic conditions, or diabetes mellitus; in patients experiencing difficulty in urination secondary to prostatic enlargement; or in patients receiving monoamine oxidase (MAO) inhibitors.
