this manual.
DOSAGE
Adults:
- General use:
- usual dose - 0.5 mg/kg/24 hours or 10 mg IM, IV or SC
- may repeat 2 to 4 times/day
- Small bowel intubation:
- 10 mg IV 15 minutes prior to intubation or, preferably, when tip of tube reaches
pyloric region
- Prevention of emesis due to chemotherapy (mild to moderate emetogenic agents):
- 10-60 mg IV, 15-30 minutes prior to chemotherapy and repeated every 4 hours as
required
- Prevention of emesis due to highly emetogenic agents:
- 1-2 mg/kg 30 min prior to and every 4 hours after chemotherapy administration
(maximum = 10mg/kg/day)
- if vomiting is controlled, subsequent doses may be reduced to 1 mg/kg/dose
- Chronic nausea:

- Total daily dose in children should not exceed 0.5 mg/kg
Reduce dosage in renal impairment:
| Creatinine clearance |
Dose |
| 10-50 mL/min |
75% of usual dose |
| < 10 mL/min |
50% of usual dose |
POTENTIAL HAZARDS OF PARENTERAL ADMINISTRATION
- parkinsonism and/or other extrapyramidal effects with high doses and/or in renal
impairment
- sedation, diarrhea; anxiety, agitation with rapid IV administration
IMPORTANT IMPLICATIONS
- may accelerate the absorption of drugs from the small bowel (e.g. diazepam, levodopa,
lithium)
- may decrease the absorption of drugs from the stomach (e.g.
digoxin)
- may enhance sedative effects of concurrently administered sedatives, hypnotics, or
tranquillizers
- may increase seizure frequency in epileptics
- may increase release of catecholamines; use with caution in patients with
pheochromocytoma or receiving MAO inhibitors
