warnings and cautions
5 WARNINGS AND PRECAUTIONS Cardiac Function Abnormalities : Increased risk for higher degree of atrioventricular blocks. Consider cardiac monitoring in patients receiving octreotide acetate injection intravenously. Bradycardia, arrhythmias, or conduction abnormalities may occur. Use with caution in at-risk patients. Dosage adjustment of cardiac medications may be necessary. ( 5.1 ) Cholelithiasis and Complications of Cholelithiasis : Monitor periodically. Discontinue if complications of cholelithiasis are suspected. ( 5.2 ) Glucose Metabolism : Hypoglycemia or hyperglycemia may occur. Glucose monitoring is recommended and anti-diabetic treatment may need adjustment. ( 5.3 ) Thyroid Function : Hypothyroidism may occur. Monitor thyroid levels periodically. ( 5.4 ) Steatorrhea and Malabsorption of Dietary Fats : New onset steatorrhea, stool discoloration, loose stools, abdominal bloating, and weight loss may occur. If new occurrence or worsening of these symptoms are reported, evaluate for potential pancreatic exocrine insufficiency. ( 5.5 ) 5.1 Cardiac Function Abnormalities Complete Atrioventricular Block Patients who receive octreotide acetate injection intravenously may be at increased risk for higher degree atrioventricular blocks. In postmarketing reports, complete atrioventricular block was reported in patients receiving IV octreotide acetate injection during surgical procedures. In the majority of patients, octreotide acetate injection was given at higher than recommended doses and/or as a continuous IV infusion. The safety of continuous IV infusion has not been established in patients receiving octreotide acetate injection for the approved indications. Consider cardiac monitoring in patients receiving octreotide acetate injection intravenously. Other Cardiac Conduction Abnormalities Other cardiac conduction abnormalities have occurred during treatment with octreotide acetate injection. In acromegalic patients, bradycardia (< 50 bpm) developed in 25%; conduction abnormalities occurred in 10% and arrhythmias occurred in 9% of patients during octreotide acetate injection therapy [see Adverse Reactions (6) ] . Other electrocardiogram (ECG) changes observed included QT prolongation, axis shifts, early repolarization, low voltage, R/S transition, and early R-wave progression. These ECG changes are not uncommon in acromegalic patients. Dose adjustments in ...

adverse reactions
6 ADVERSE REACTIONS The following clinically significant adverse reactions are described elsewhere in the labeling: • Complete Atrioventricular Block [see Warnings and Precautions (5.1) ] • Cholelithiasis and Complications of Cholelithiasis [see Warnings and Precautions (5.2) ] • Hyperglycemia and Hypoglycemia [see Warnings and Precautions (5.3) ] • Thyroid Function Abnormalities [see Warnings and Precautions (5.4) ] • Steatorrhea and Malabsorption of Dietary Fats [see Warnings and Precautions (5.5) ] • Changes in Vitamin B12 Levels [see Warnings and Precautions (5.6) ] Most common adverse reactions (incidence > 10%) in patients with acromegaly are gallbladder abnormalities, sinus bradycardia, diarrhea, loose stools, nausea, abdominal discomfort, hyperglycemia, and hypothyroidism. In other patients, most common adverse reactions (incidence > 10%) are gallbladder abnormalities. ( 6.1 ). To report SUSPECTED ADVERSE REACTIONS, contact Gland Pharma Limited at 864-879-9994 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. Gallbladder Abnormalities Gallbladder abnormalities, especially stones and/or biliary sludge, frequently develop in patients on chronic octreotide acetate injection therapy [see Warnings and Precautions (5.1) ]. In clinical trials (primarily patients with acromegaly or psoriasis), the incidence of biliary tract abnormalities was 63% (27% gallstones, 24% sludge without stones, 12% biliary duct dilatation). The incidence of stones or sludge in patients who received octreotide acetate injection for 12 months or longer was 52%. Less than 2% of patients treated with octreotide acetate injection for 1 month or less developed gallstones. Cardiac In acromegalics, sinus bradycardia (< 50 bpm) developed in 25%; conduction abnormalities occurred in 10% and arrhythmias developed in 9% of patients during octreotide acetate injection therapy [see Warnings and Precautions (5.1) ]. Gastrointestinal Diarrhea, loose stools, nausea, and abdominal discomfort were each seen in 34% to 61% of acromegalic patients in U.S. studies. 2.6% of the patients discontinued therapy due...
