Boxed Warning

Physician Labeling Rule (PLR conversion); additions and/or revisions underlined:

WARNING: SUICIDAL THOUGHTS AND BEHAVIORS and HYPERTENSIVE CRISIS WITH SIGNIFICANT TYRAMINE USE

Suicidal Thoughts and Behaviors

Antidepressants increased the risk of suicidal thoughts and behaviors in pediatric and young adult patients in short-term studies. Closely monitor all antidepressant-treated patients for clinical worsening, and for emergence of suicidal thoughts and behaviors. PARNATE is not approved for use in pediatric patients.

Hypertensive Crisis with Significant Tyramine Use

Excessive consumption of foods or beverages with significant tyramine content or the use of certain drugs with PARNATE or after PARNATE discontinuation can precipitate hypertensive crisis. Monitor blood pressure and allow for medication-free intervals between administration of PARNATE and interacting drugs. Instruct patients to avoid ingestion of foods and beverages with high tyramine content.

4 Contraindications

PLR Conversion; Revised as below into subsections.

Table 1: Products Contraindicated with the Use of Parnate added – please refer to label for complete information.

4.1 Combination with Certain Drugs

Concomitant use of PARNATE or use in rapid succession with the products in Table 1 is

contraindicated. Such use may cause severe or life-threatening reactions such as hypertensive crises or serotonin syndrome. Medication-free periods between administration of PARNATE and contraindicated agents are recommended.

Table 1: Products Contraindicated with the Use of PARNATE

4.2 Pheochromocytoma and Catecholamine-Releasing Paragangliomas

PARNATE is contraindicated in the presence of pheochromocytoma or other catecholamine- releasing paragangliomas because such tumors secrete pressor substances and can lead to hypertensive crisis.
