Question please awnser:D?

Marii • Second baby my first baby just turned 1 😯😊💙💜💛💓💓💓💓💖💖
So I think my SO is having some symptoms due to my pregnancy he's very nauseous and his nose bleeds every once in a while I'm taking a medicine for my nausea called ondansetron it's 4 mg I think it's similar to zofran..would it hurt for him to take one?
