Is there a safe anti-nausea medication i can give my 9 month old daughter with the stomach virus?

Not over the counter: For a 9 month old, there's no safe over the counter medication. You can see your pediatrician and upon evaluation if the nausea is severe and she can't tolerate anything by mouth, she might need IV fluids. There are also some medications in the form of injection, syrup or suppository that might help your daughter at very low and measured doses (based on her body weight) to help with her nausea.
