Overview
INDICATIONS AND USAGE VARIBAR THIN LIQUID is indicated for modified barium swallow examinations to evaluate the oral and pharyngeal function and morphology in adult and pediatric patients. VARIBAR THIN LIQUID is a radiopaque contrast agent indicated for use in modified barium swallow examinations to evaluate the oral and pharyngeal function and morphology in adult and pediatric patients ( 1 )
Indications & Usage
VARIBAR THIN LIQUID is indicated for modified barium swallow examinations to evaluate the oral and pharyngeal function and morphology in adult and pediatric patients. VARIBAR THIN LIQUID is a radiopaque contrast agent indicated for use in modified barium swallow examinations to evaluate the oral and pharyngeal function and morphology in adult and pediatric patients ( 1 )
Dosage & Administration
For oral use only– once reconstituted, administer by infant bottle, syringe, spoon, or cup. The recommended dose is: ● Adults: 5 mL ● Pediatric patients 6 months and older: 1 mL to 3 mL ● Pediatric patients younger than 6 months of age: 0.5 mL to 1 mL During a single modified barium swallow examination, multiple doses may be administered Maximum cumulative dose: 80 mL ( 2.1 ) Must reconstitute supplied powder with water prior to use. See Full Prescribing Information for reconstitution instructions ( 2.2 ) 2.1 Recommended Dosing and Administration Instructions The recommended dose of reconstituted VARIBAR THIN LIQUID administered orally by infant bottle, syringe, spoon, or cup is: Adults: 5 mL Pediatric patients 6 months and older: 1 mL to 3 mL Pediatric patients younger than 6 months of age: 0.5 mL to 1 mL During a single modified barium swallow examination, multiple doses of VARIBAR THIN LIQUID may be administered, to assess the patient during multiple swallows and different radiographic views. The maximum cumulative dose is 80 mL. For oral use only Advise patients to hydrate following the barium sulfate procedure. 2.2 Instructions for Reconstitution The VARIBAR THIN LIQUID powder must be reconstituted prior to administration by a healthcare provider according to the following instructions: Add water to the fill line on the bottle label Replace the lid securely Invert the bottle and tap with fingers to mix the powder into the water Shake vigorously for 30 seconds. Let stand for 5 minutes Refill with water to the fill line on the bottle label and reshake thoroughly. Once reconstituted, write the discard after date on the immediate container label. After reconstitution, store in refrigerator at 2°C to 8°C (36ºF to 46ºF) for up to 72 hours. Reconstitution yields approximately 300 mL of VARIBAR THIN LIQUID oral suspension containing 0.4 grams of barium sulfate per mL (40% w/v) and should be homogeneous and white to lightly colored.
Warnings & Precautions
Hypersensitivity reactions: Emergency equipment and trained personnel should be immediately available ( 5.1 ) Intra-abdominal leakage: May occur in conditions such as GI fistula, ulcer, inflammatory bowel disease, appendicitis or diverticulitis, severe stenosis or obstructing lesions of the GI tract ( 5.2 ) Delayed GI transit and obstruction: Patients should maintain adequate hydration in days following barium sulfate procedure to avoid obstruction or impaction ( 5.3 ) Aspiration pneumonitis: Aspiration may occur during the modified barium swallow examination, monitor the patient for aspiration ( 5.4 ) 5.1 Hypersensitivity Reactions Barium sulfate preparations contain a number of excipients, including natural and artificial flavors and may induce serious hypersensitivity reactions. The manifestations include hypotension, bronchospasm and other respiratory impairments, and dermal reactions including rashes, urticaria and itching. A history of bronchial asthma, atopy, food allergies, or a previous reaction to a contrast agent may increase the risk for hypersensitivity reactions. Emergency equipment and trained personnel should be immediately available for treatment of a hypersensitivity reaction. 5.2 Intra-abdominal Barium Leakage The use of VARIBAR THIN LIQUID is contraindicated in patients at high risk of perforation of the GI tract [see Contraindications ( 4 )] . Administration of VARIBAR THIN LIQUID may result in leakage of barium from the GI tract in the presence of conditions such as carcinomas, GI fistula, inflammatory bowel disease, gastric or duodenal ulcer, appendicitis, or diverticulitis, and in patients with a severe stenosis at any level of the GI tract, especially if it is distal to the stomach. The barium leakage has been associated with peritonitis and granuloma formation. 5.3 Delayed Gastrointestinal Transit and Obstruction Orally administered barium sulfate may accumulate proximal to a constricting lesion of the colon, causing obstruction or impaction with development of baroliths (inspissated barium associated with feces) and may lead to abdominal pain, appendicitis, bowel obstruction, or rarely perforation. Patients with the following conditions are at higher risk for developing obstruction or baroliths: severe stenosis at any level of the GI tract, impaired GI motility, electrolyte imbalance, dehydration, on a low residue diet, taking medications that delay GI motility, constipation, pediatric patients with cystic fibrosis or Hirschsprung disease, and the elderly [see Use in Specific Populations ( 8.4 , 8.5 )]. To reduce the risk of delayed GI transit and obstruction, patients should maintain adequate hydration after the barium sulfate procedure. 5.4 Aspiration Pneumonitis The use of VARIBAR THIN LIQUID is contraindicated in patients with trachea-esophageal fistula [see Contraindications ( 4 )] . Oral administration of barium is associated with aspiration pneumonitis, especially in patients with a history of food aspiration or with compromised swallowing mechanism. Vomiting following oral administration of barium sulfate may lead to aspiration pneumonitis. In patients at risk for aspiration, begin the procedure with a small ingested volume of VARIBAR THIN LIQUID. Monitor the patient closely for aspiration, discontinue administration of VARIBAR THIN LIQUID if aspiration is suspected, and monitor for development of aspiration pneumonitis. 5.5 Systemic Embolization Barium sulfate products may occasionally intravasate into the venous drainage of the GI tract and enter the circulation as a "barium embolus" leading to potentially fatal complications which include systemic and pulmonary embolism, disseminated intravascular coagulation, septicemia and prolonged severe hypotension. Although this complication is exceedingly uncommon after oral administration of a barium sulfate suspension, monitor patients for potential intravasation when administering barium sulfate.
Contraindications
VARIBAR THIN LIQUID is contraindicated in patients with: known or suspected perforation of the gastrointestinal (GI) tract known obstruction of the GI tract high risk of GI perforation such as those with a recent GI perforation, acute GI hemorrhage or ischemia, toxic megacolon, severe ileus, post GI surgery or biopsy, acute GI injury or burn, or recent radiotherapy to the pelvis high risk of aspiration such as those with known or suspected tracheo-esophageal fistula or obtundation known severe hypersensitivity to barium sulfate or any of the excipients of VARIBAR THIN LIQUID Known or suspected perforation of the gastrointestinal (GI) tract ( 4 ) Known obstruction of the GI tract ( 4 ) Conditions associated with high risk of GI perforation or aspiration ( 4 ) Known hypersensitivity to barium sulfate or any of the excipients of VARIBAR THIN LIQUID ( 4 )
Adverse Reactions
The following adverse reactions have been identified from spontaneous reporting or clinical studies of barium sulfate administered orally. Because the reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or to establish a causal relationship to drug exposure: Nausea, vomiting, diarrhea and abdominal cramping Serious adverse reactions and fatalities include aspiration pneumonitis, barium sulfate impaction, intestinal perforation with consequent peritonitis and granuloma formation, vasovagal and syncopal episodes Common adverse reactions include nausea, vomiting, diarrhea and abdominal cramping ( 6 ) To report SUSPECTED ADVERSE REACTIONS, contact Bracco Diagnostics Inc at 1-800-257-5181 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch
