Can I give my 9yr old 4mg zofran?

But from my experience if he can keep it down for 20-30 and then doesn’t throw up your are good and you can give the other half tablet (2mg) then 6-8 hrs later u can give 2 more mg if needed. At night though I’ll just give him the other 2mg in 30-40 min make sure nausea goes away and put him back to bed. 4 mg is usually a chemo therapy dose in young kids so for stomach bugs it works well if you give 2 mg and it’s not too severe and if during the day just wait 6-8 hrs maybe give another 2mg just in case but at night like I said I just give the other half tab to make sure he is ok through the night! If it’s severe nausea and food poisoning like he keeps throwing up over and over though that he can’t keep it down and that lasts longer than maybe 12 hrs max I would check w a dr he will get dehydrated and some things like listeria salmonella can be dangerous. I am a pharmacist so I just kind of see how it goes and I judge it by symptoms severity and other stuff it’s harder for people if they don’t know as much as I do ab medical stuff so if in doubt and fever also and diarrhea urgent care is probably the best choice. My son never has fever or diarrhea but if he gets all 3 MD should probably be consulted. He woke up tonight for example it’s late he felt nauseous no fever no diarrhea we all ate the same thing and everyone is fine so I am thinking stomach bug. Hopefully we all won’t get it! Gave him 2 mg it’s been 30 min he still feels nauseous but has not thrown up he says it’s starting to get better so it is probably slowly absorbing now. I’ll give him another 20-30 min so 1 hr if he is much better I will probably give him the other half so another 2 mg and put him to bed that should last the night and I’ll see how he feels in am. But again severe food poisoning w diarrhea or fever can’t keep anything down even water for more than few min may be more serious so don’t go more than 8-12 hrs especially like I said w fever also try giving rehydration fluids pedialite ect if he can’t keep that down go to urgent care may need IV and check for salmonella and some other more serious bugs!
