4 Contraindications

Additions and/or revisions underlined:

ZELAPAR is contraindicated in patients with:

  • Concomitant use of opioid drugs (e.g., meperidine, tramadol, or methadone). Serotonin syndrome, a potentially serious condition, which can result in death, has been reported with concomitant use of meperidine (e.g., Demerol and other trade names). At least 14 days should elapse between discontinuation of ZELAPAR and initiation of treatment with these medications [see Warnings and Precautions (5.2)].

  • Concomitant use of other drugs in the monoamine oxidase inhibitor (MAOI) class or other drugs that are potent inhibitors of monoamine oxidase, including linezolid), because of an increased risk for hypertensive crisis [see Warnings and Precautions (5.1)]. At least 14 days should elapse between discontinuation of ZELAPAR and initiation of treatment with any MAO inhibitor.

  • Concomitant use of St. John’s wort or cyclobenzaprine (a tricyclic muscle relaxant).

  • Concomitant use of dextromethorphan, because of reported episodes of psychosis or bizarre behavior.

5 Warnings and Precautions

5.10 Risk for Patients with Phenylketonuria

Additions and/or revisions underlined:

Phenylalanine can be harmful to patients with phenylketonuria (PKU). ZELAPAR contains phenylalanine, a component of aspartame. Each ZELAPAR 1.25 mg tablet contains 1.25 mg phenylalanine. Patients taking the 2.5 mg dose of ZELAPAR will receive 2.5 mg phenylalanine. Before prescribing ZELAPAR to a patient with PKU, consider the combined daily amount of phenylalanine from all sources, including ZELAPAR.

6 Adverse Reactions

6.1 Clinical Trials Experience

Additions and/or revisions underlined:

Table 1: Adverse Reactions* in Double-Blind, Placebo-Controlled Trials with an Incidence greater than or equal to 2% of Patients Treated with ZELAPAR and More Frequent than the Placebo Group

7 Drug Interactions

Additions and/or revisions underlined:

7.1 Opioid Drugs

Because serious, sometimes fatal reactions have been precipitated with concomitant use of opioid drugs (e.g., meperidine and its derivatives, methadone, or tramadol) and MAOIs, including selective MAO-B inhibitors, concomitant use of these drugs with ZELAPAR is contraindicated [see Contraindications (4) and Warnings and Precautions (5.2)]. At least 14 days should elapse between discontinuation of ZELAPAR and initiation of treatment with these drugs.

Additions and/or revisions underlined:

7.3 MAO Inhibitors

ZELAPAR is contraindicated for concomitant use with other drugs in the MAOI class or other drugs that are potent inhibitors of monoamine oxidase (including linezolid, an oxazolidinone antibacterial, which also has reversible nonselective MAO inhibition activity) because of the increased risk for hypertensive crisis [see Contraindications (4) and Warnings and Precautions (5.1)]. At least 14 days should elapse between discontinuation of ZELAPAR and initiation of treatment with other MAOIs.

8 Use in Specific Populations

8.1 Pregnancy

PLLR conversion; additions and/or revisions underlined:

Risk Summary

There are no adequate data on the developmental risk associated with the use of ZELAPAR in pregnant women. In animal studies, administration of selegiline during pregnancy was associated with developmental toxicity (decreased embryofetal and postnatal offspring growth and survival) at doses greater than those used clinically.

In the U.S. general population, the estimated background risk of major birth defects and of miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. The background risk of major birth defects and miscarriage in the indicated population is unknown.

8.2 Lactation

PLLR conversion; additions and/or revisions underlined:

Risk Summary

There are no data on the presence of selegiline or its metabolites in human milk, the effects on the breastfed infant, or the effects on milk production. Selegiline and metabolites were detected in rat milk at levels higher than those in maternal plasma.

Because of the potential for serious adverse reactions in breastfed infants from ZELAPAR, including the potential for hypertensive reactions, advise a woman that breastfeeding is not recommended during treatment with ZELAPAR and for 7 days after the final dose.
