A member asked:
Is zofran (ondansetron) 4mg safe if you have a healthy heart? how long after stopping the drug (i took one dose) does the risk for cardiac issues cease?
A doctor has provided 1 answer
Ondansetron: Zofran (ondansetron) in doses greater than 16 mg at a time has been implicated in prolonging the qt interval. This effect would last for a few hours while the drug was in the system. A single 4 mg dose does not carry this risk.
