There are many meclizine hydrochloride products available (Antivert®, Bonine®, Dramamine® Less Drowsy Formula). Some are available over-the-counter and approved to treat motion sickness, while others are available by prescription only and licensed to treat both motion sickness and vertigo.
There are two different forms of the drug: oral tablets and chewable tablets. Both medications are taken by mouth, typically once or twice a day. Prescription oral meclizine tablets are available in three strengths, while the non-prescription tablets and chewable tablets are only available in one strength.
Both tablet forms of meclizine should be stored at room temperature, away from moisture and heat. If you are taking this drug on a regular schedule and forget a dose, take your missed dose as soon as you remember. If it is almost time for your next dose, skip the missed dose and continue with your regular schedule. Do not take a double dose of meclizine, as an overdose with this medication can cause serious problems.
