Is Dramamine useful to treat nausea or dry heaving?

Dramamine is an over-the-counter (OTC) medication that is traditionally used to treat the symptoms that are associated with motion sickness eg. dizziness, nausea and vomiting. Dramamine can also be taken to reduce mild nausea associated with other illnesses like flu or food poisoning.

Dramamine can be used "when required" for treatment of occasional nausea symptoms, or taken regularly to prevent chronic nausea.
