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. |
| Molecular Weight | 233.39 |
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 | No known fetal harm; barium sulfate is not absorbed systemically. Use only if clearly needed. |
| 2nd trimester | Considered safe; minimal systemic absorption. |
| 3rd trimester | Considered safe; avoid if risk of aspiration due to thick consistency. |
Clinical note
Comprehensive clinical and safety monograph for VARIBAR THIN HONEY (VARIBAR THIN HONEY).
| Placental transfer | No significant placental transfer; barium sulfate remains in GI tract and is not absorbed. |
| Breastfeeding | Barium sulfate is not absorbed from the GI tract, thus not expected to be excreted into breast milk. Compatible with breastfeeding. |
| Lactation Rating |
■ FDA Black Box Warning
None.
| Serious Effects |
Known or suspected gastrointestinal perforationKnown or suspected gastrointestinal obstructionKnown hypersensitivity to barium sulfateSevere asthma or respiratory compromise (risk of aspiration)
| 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 |
| Food/Dietary | Avoid food and drink for 4 hours prior to administration. After the procedure, increase fluid intake to facilitate barium excretion. No specific dietary restrictions otherwise. |
Loading safety data…
| L1 |
| 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. |
| Fertility Effects | No known effects on fertility based on lack of systemic absorption and inert nature of barium sulfate. |
| Clinical Pearls |
| VARIBAR THIN HONEY is a barium sulfate suspension used for opacification of the gastrointestinal tract. Use thin honey viscosity for patients with mild dysphagia who can tolerate nectar-thick liquids. Monitor for aspiration risk; have suction equipment ready. Ensure adequate hydration before and after study to prevent barium impaction. |
| Patient Advice | Do not eat or drink anything for at least 4 hours before the procedure. · Inform your provider if you have a history of bowel obstruction or perforation. · You may experience a metallic taste or transient constipation after the exam. · Drink plenty of fluids after the procedure to help eliminate barium. |
