VARIBAR THIN HONEY
Clinical safety rating: caution
Comprehensive clinical and safety monograph for VARIBAR THIN HONEY (VARIBAR THIN HONEY).
Barium sulfate is a radiopaque agent that coats the mucosal surfaces of the gastrointestinal tract, absorbing or scattering X-rays to provide contrast in radiographic imaging.
| Metabolism | Not metabolized; excreted unchanged in feces. |
| Excretion | Barium sulfate is insoluble and not absorbed; >99% eliminated unchanged in feces via gastrointestinal transit. No renal or biliary elimination. |
| Half-life | Not applicable (non-absorbed contrast agent). |
| Protein binding | 0% (not absorbed, no systemic exposure). |
| Volume of Distribution | 0 L/kg (confined to gastrointestinal lumen due to lack of absorption). |
| Bioavailability | 0% via oral route (not absorbed systemically). |
| Onset of Action | Oral administration: within 1 hour for gastrointestinal opacification. |
| Duration of Action | 4–6 hours for small bowel follow-through; up to 24 hours for colonic transit, depending on motility. |
20-40 mL orally as a single dose; may repeat if necessary.
| Dosage form | SUSPENSION |
| Renal impairment | No dose adjustment required for renal impairment. |
| Liver impairment | No dose adjustment required for hepatic impairment. |
| Pediatric use | Weight-based: 0.5-1 mL/kg orally as a single dose; maximum 40 mL. |
| Geriatric use | No specific dose adjustment; use with caution due to aspiration risk. |
| 1st trimester | Consult provider |
| 2nd trimester | Consult provider |
| 3rd trimester | Consult provider |
Clinical note
Comprehensive clinical and safety monograph for VARIBAR THIN HONEY (VARIBAR THIN HONEY).
| Breastfeeding | Excreted in breast milk only in negligible amounts; M/P ratio not applicable due to lack of systemic absorption; considered compatible with breastfeeding. |
| Teratogenic Risk | No fetal risk in any trimester as barium sulfate is not absorbed systemically; no known teratogenic or embryotoxic effects. |
| Fetal Monitoring | Routine fetal monitoring not required; ensure adequate hydration before and after procedure; monitor for allergic reactions if administering via oral route. |
■ FDA Black Box Warning
None.
| Serious Effects |
["Known or suspected gastrointestinal perforation","Known or suspected gastrointestinal obstruction","Known hypersensitivity to barium sulfate"]
| Precautions | ["Risk of aspiration leading to pneumonitis or granuloma formation","Risk of bowel perforation if administered in patients with known or suspected gastrointestinal perforation or obstruction","Possible allergic reactions in patients with hypersensitivity to barium sulfate"] |
