Meclazine is used in hydrochlorate form, as an anti-emetic: it's one of the various antihistamines on the market, widely used as preventative against dizzyness, motion sickness, those sorts of things. Side effects are the usual drousyness associated with antihistamines, but YMMV, of course. It is also supposedly tasteless, which to my personal experience is a vast improvement over the previously-widely used Drammamine.
