warnings and cautions
5 WARNINGS AND PRECAUTIONS Radiation Risk : Gallium Ga 68 dotatate contributes to a patient’s overall long-term cumulative radiation exposure. Ensure safe handling and preparation procedures to protect patients and health care workers from unintentional radiation exposure. Restrict close contact with infants and pregnant women during the first 12 hours after administration of gallium Ga 68 dotatate. ( 5.1 ) Hypersensitivity Reactions : Most reported reactions were rash and pruritus and reversible either spontaneously or with routine symptomatic management. ( 5.2 ) Risk for Image Misinterpretation : The uptake of gallium Ga 68 dotatate can be seen in a variety of tumor types other than NETs (e.g., those derived from neural crest tissue), in sites of splenosis or other pathologic conditions, and as a normal physiologic variant (e.g., uncinate process of the pancreas). ( 5.3 ) 5.1 Radiation Risk Gallium Ga 68 dotatate contributes to a patient’s overall long-term cumulative radiation exposure. Long-term cumulative radiation exposure is associated with an increased risk of cancer. Ensure safe handling and preparation radiolabeling procedures to protect patients and health care workers from unintentional radiation exposure [see Dosage and Administration ( 2.1 )] . Avoid close contact with infants and pregnant women during the first 12 hours after administration of gallium Ga 68 dotatate injection. 5.2 Hypersensitivity Reactions Hypersensitivity reactions following administration of somatostatin receptor imaging agents predominantly consisted of cutaneous reactions, such as rash and pruritus. Reactions reversed either spontaneously or with routine symptomatic management. Less frequently hypersensitivity reactions included angioedema or cases with features of anaphylaxis. 5.3 Risk for Image Misinterpretation The uptake of gallium Ga 68 dotatate reflects the level of somatostatin receptor density in NETs. However, uptake can also be seen in a variety of other tumor types (e.g., those derived from neural crest tissue). Increased uptake might also be seen in sites of splenosis or other pathologic conditions (e.g., thyroid disease or subacute inflammation) or might occur as a normal physiologic variant (e.g., uncinate process of the pancreas). PET images with gallium Ga 68 dotatate should be interpreted visually and the uptake may need to be confirmed by histopatholo...

adverse reactions
6 ADVERSE REACTIONS The following clinically significant adverse reactions are described elsewhere in the labeling: Hypersensitivity reactions [see Warnings and Precautions ( 5.2 )] Nausea, vomiting, and injection site pain and burning sensation were all reported during post-approval use. ( 6 ) To report SUSPECTED ADVERSE REACTIONS, contact Novartis Pharmaceuticals Corporation at 1-888-669-6682 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Clinical Trials Experience The safety of gallium Ga 68 dotatate was evaluated in three single center studies [see Clinical Studies ( 14 )] and in a survey of the scientific literature. No serious adverse reactions were identified. 6.2 Postmarketing Experience The following adverse reactions have been identified during post-approval use of NETSPOT or other somatostatin receptor imaging agents. 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 the drug. Gastrointestinal Disorders: Nausea and vomiting General Disorders and Administration Site Conditions: Injection site pain and burning sensation Immune System Disorders: Hypersensitivity reactions, predominantly rash, pruritus, less frequently angioedema or features of anaphylaxis.
