What's the pill meclizine used for?

Motion sickness/vert: Meclizine, aka bonine, antivert, (meclizine) menid, dramamine: belongs to a class of meds called antiemtic--used to treat motion sickness ad vertigo. It also has ancholinergic effects, thus can help with itching (mild effect) as well. Meclizine is available otc, because it has relatively low/mild side effects and thus safer for use. If you have additional concern/question, consult doc. Good luck.

Drug experimentation: Dr nyughen was quite clear and accurate about this class of drugs. I wonder why you ask the question, being suspicious that teenage drug experimentation may be at play. If i'm wrong, i apologize. If i'm correct, please take your teen or yourself for drug assessment.
