How Does Dramamine Work?

Depending on the formulation, Dramamine may contain either dimenhydrinate or meclizine as the main ingredient.

The active ingredient in regular Dramamine is dimenhydrinate.

It blocks histamine receptors in the brain and gut, preventing nausea and vomiting.

The active ingredient in Dramamine Less Drowsy is meclizine.

Meclizine is also an antihistamine, but it is formulated to provide relief for 24 hours while minimizing drowsiness.
