            Warnings

            Black Box Warnings

            Prescribing physicians should understand severe and fatal toxicities of chrysotherapy

            Thorough patient discussion explaining adverse reactions is essential; encourage patients to report any adverse reactions

            Monitor for signs of gold toxicity (ie, decreased hemoglobin, leukopenia <4,000/cu.mm, granulocytes <1,500/cu.mm, platelets <150,000/cu.mm, proteinuria, hematuria, pruritus, rash, stomatitis, persistent diarrhea) and establish baseline measurements before prescribing

            Should be reserved for use in certain patients with active rheumatoid arthritis

            Contraindications

            Hypersensitivity to gold

            Pts who have had previous gold-induced disorders (anaphylaxis, necrotizing enterocolitis, pulmonary fibrosis, dermatitis, bone marrow suppression, or other hematologic disorder)

            Cautions

            Not to be used as sole agent in Tx of RA

            No evidence gold compounds induce remission of RA

            Gold toxicity:

            • Hemoglobin (decr)
            • Leukopenia (WBC <4000/cu.mm) [4 x10^9/L]
            • Granulocytes (<1500/cu.mm) [1.5 x10^9/L]
            • Platelets (<150 x 10^3/cu.mm) [150 x10^9/L]
            • Proteinuria, hematuria, pruritus, rash, stomatitis, chronic diarrhea

            D/C if evidence of anaphylaxis

            If nitritoid reaction (flushing, tachycardia, faintness) w/in minutes of inj, resume Tx only with caution in pts w/compromised CV status
