administered with tramadol. Steroid administration was excluded from these clinical trials. Serotonin syndrome occurring with overdose of Zofran alone has also been reported. In these trial(s) patients were receiving multiple concomitant perioperative and postoperative medications in both treatment groups. Pediatric cases consistent with serotonin syndrome have been reported after inadvertent oral overdoses of ondansetron (exceeding estimated ingestion of 5 mg per kg) in young children. Reported symptoms included somnolence, agitation, tachycardia, tachypnea, hypertension, flushing, mydriasis, diaphoresis, myoclonic movements, horizontal nystagmus, hyperreflexia, and seizure.
Postoperative 16 mg administered 1 hour before induction of anesthesia. Drug Interaction Studies CYP 3A4 Inducers: Ondansetron elimination may be affected by cytochrome P-450 inducers. Integumentary: Rash (approximately 1 of patients). Tramadol Although no pharmacokinetic drug interaction between ondansetron and tramadol has been observed, data from 2 small trials indicate that when used together, Zofran may increase patient-controlled administration of tramadol. In two trials the response rates to Zofran 4 mg three times a day in patients younger than 12 years was similar to Zofran 8 mg three times daily in patients 12 to 18 years. The background risk of major birth defects and miscarriage for the indicated population is unknown. Pediatric Use The safety and effectiveness of orally administered Zofran have been established in pediatric patients 4 years and older for the prevention of nausea and vomiting associated with moderately emetogenic cancer chemotherapy. Pediatric Trials Three openlabel, single-arm, non-US trials have been performed with 182 pediatric patients aged 4 to 18 years with cancer who were given a variety of cisplatin or noncisplatin regimens.

Nonclinical Toxicology Carcinogenesis, Mutagenesis, Impairment of Fertility Carcinogenic effects were not seen in 2-year studies in rats and mice with oral ondansetron doses up ebuyer promo code january 2019 to 10 mg/kg per day and 30 mg/kg per day, respectively (approximately 4 and 6 times the maximum recommended human oral.
