( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Orphalan at 1-800-961-8320 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Common Adverse Reactions Table 3 presents common adverse reactions over a 24-week period from Trial 1, a prospective, randomized, multi-center study that was conducted in adult patients with Wilson's disease who were de-coppered and tolerant to penicillamine [see Clinical Studies (14) ] . Patients were either switched to receive CUVRIOR (N=26) or continued to receive penicillamine (N=27). Table 3: Common Adverse Reactions Adverse reactions that occurred in >5% of…

CUVRIOR is contraindicated in patients with hypersensitivity to trientine or to any of the excipients in CUVRIOR [see Warnings and Precautions (5.4) ] . Hypersensitivity to trientine or to any of the excipients in CUVRIOR. ( 4 )

Mineral Supplements (e.g. iron, zinc, calcium, magnesium): Avoid concomitant use. If concomitant use is unavoidable ( 2.2 , 7.1 ): Iron : Take CUVRIOR at least 2 hours before or 2 hours after iron. Other Mineral Supplements : Take CUVRIOR at least 1 hour before or 2 hours after other mineral supplements. Other Drugs for Oral Administration : Take CUVRIOR at least 1 hour apart from any other oral drug. ( 2.2 , 7.1 ) 7.1 Mineral Supplements and Other Oral Drugs CUVRIOR has the potential to chelate non-copper cations in mineral supplements and other oral drugs, and could be rendered ineffective prior to systemic absorption. Mineral Supplements Avoid concomitant use of mineral supplements such as iron, zinc, calcium, or magnesium with CUVRIOR because they may reduce the absorption of CUVRIOR. However, if iron deficiency develops [see Warnings and Precautions (5.3) ], iron supplementation may be given in short courses, but because iron and CUVRIOR each inhibit absorption of the other, administer CUVRIOR at least 2 hours before or 2 hours after administration of an iron supplement [see Dosage and Administration (2.2) ]. If concomitant use of other mineral supplements is unavoidable, administer CUVRIOR at least 1 hour before or 2 hours after administration of other mineral supplements. Other Drugs for Oral Administration Administer CUVRIOR at least 1 hour apart from any other oral drug.
