Meclizine
chemical compound
Meclizine, sold under the brand name Bonine, among others, is an antihistamine used to treat motion sickness and dizziness (vertigo). It is taken by mouth. Effects generally begin in an hour and last for up to a day.
Common side effects include sleepiness and dry mouth. Serious side effects may include allergic reactions. Use in pregnancy appears safe, but has not been well studied; use in breastfeeding is of unclear safety. It is believed to work in part by anticholinergic and antihistamine mechanisms.
Meclizine was patented in 1951 and came into medical use in 1953. It is available as a generic medication and often over the counter. In 2023, it was the 137th most commonly prescribed medication in the United States, with more than 4 million prescriptions.
This brief starts where responsible research should: with the source description of “Meclizine” as chemical compound. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as chemical compound. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Jul 21, 2026. The linked authority identifier is Q386441. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1951, 1953 and 2023.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
