Vicks VapoRub is generally considered safe to use during pregnancy when applied topically as directed on the chest, throat, and back. It should never be used internally (inside the nose or mouth), as camphor, an active ingredient, can be harmful if ingested or applied internally. Pregnant individuals should avoid applying it to broken or irritated skin and wash their hands after use to prevent accidental ingestion. Other Vicks products such as Vicks VapoPatch and Vicks VapoShower tablets are also considered safe, while nasal sprays containing certain active ingredients like oxymetazoline hydrochloride should be avoided unless advised by a healthcare provider. It's always recommended to consult with a healthcare provider before using any medication or remedy during pregnancy.
