What is Ondansetron 4mg used for?

Dosage instructions
Dosage depends on age, medical condition, and reason for use. Ondansetron 4mg may be taken once or multiple times a day at set intervals. Follow the exact dosing schedule given by your healthcare provider. Taking more than prescribed does not improve results and increases side-effect risk. Missed doses should be taken as soon as remembered unless it is near the next dose.
Side effects
Common side effects of Ondansetron 4mg include headache, constipation, dizziness, and mild tiredness. Some people may experience stomach discomfort or flushing.

Drug interactions
Ondansetron 4mg may interact with medicines that affect heart rhythm, such as certain antibiotics, antidepressants, and anti-arrhythmic drugs.
