5 WARNINGS AND PRECAUTIONS Hypersensitivity Reactions: Hypersensitivity reactions including dyspnea, edema, rash, erythema, and pruritus have been reported. Have treatment measures available prior to Ioflupane I 123 Injection administration. ( 5.1 ) Thyroid Accumulation of Iodine-123: Thyroid uptake of iodine-123 may result in an increased long-term risk for thyroid neoplasia. ( 2.2 , 5.2 ) Radiation Risk: Ensure safe handling to minimize radiation exposure to the patient and healthcare providers. Advise patients to hydrate before and after administration and to void frequently after administration. ( 2.1 , 5.3 ) 5. 1 Hypersensitivity Reactions Hypersensitivity reactions, including dyspnea, edema, rash, erythema, and pruritus, have been reported following Ioflupane I 123 Injection administration [ see Adverse Reactions ( 6.2 ) ]. The reactions have generally occurred within minutes of Ioflupane I 123 Injection administration and have either resolved spontaneously or following the administration of corticosteroids and antihistamines. Ioflupane I 123 Injection is contraindicated in patients with known serious hypersensitivity to ioflupane I-123 [ see Contraindications ( 4 ) ]. Have treatment measures available and monitor patients for symptoms or signs of a hypersensitivity reaction. 5.2 Thyroid Accumulation of Iodine-123 Ioflupane I 123 Injection may contain up to 6% of free iodide (iodine-123). Thyroid uptake of iodine-123 may result in an increased long-term risk for thyroid neoplasia. To decrease thyroid accumulation of iodine-123, block the thyroid gland before administration of Ioflupane I 123 Injection [ see Dosage and Administration ( 2.2 ) ]. 5.3 Radiation Risk Ioflupane I 123 Injection contributes to a patient’s overall long-term cumulative radiation exposure. Long-term cumulative radiation exposure is associated with an increased risk for cancer. Ensure safe handling to minimize radiation exposure to patients and healthcare providers. Advise patients to hydrate before and after administration and to void frequently after administration [see Dosage and Administration ( 2.1 )].

6 ADVERSE REACTIONS The following clinically significant adverse reaction is described elsewhere in the labeling: • Hypersensitivity Reactions [ see Warnings and Precautions ( 5.1 ) ] The following adverse reactions were reported at ≤1%: headache, nausea, vertigo, dry mouth and dizziness.

The data from clinical trials reflect exposure to Ioflupane I 123 Injection in 942 subjects with a mean age of 66 years (range 25 years to 90 years). Among these subjects, 42% were female and 99% White. Subjects received 88 MBq to 287 MBq (2 mCi to 8 mCi) [median 173 MBq (4.7 mCi)] intravenously as a single dose. The recommended dose of Ioflupane I 123 Injection is 111 MBq to 185 MBq (3 mCi to 5 mCi) [ see Dosage and Administration ( 2.3 ) ]. The following adverse reactions were reported at a rate of 1% or less: headache, nausea, vertigo, dry mouth, and dizziness. 6.2 Postmarketing Experience The following adverse reactions have been identified during postapproval use of Ioflupane I 123 Injection. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
