How does dramamine work?
gpt
Dramamine is an antihistamine. It reduces the sensitivity of your inner ear, the part of your body that controls balance and orientation. By making your inner ear less sensitive, it means you will also be less sensitive to movements that are causing your nausea in the first place. That's why Dramamine only works for motion sickness and not other kinds of nausea.
