Is Prevacid an antihistamine

No, Prevacid is not an antihistamine. It is a proton pump inhibitor (PPI) that is primarily used to treat conditions related to excess stomach acid, such as gastroesophageal reflux disease (GERD) and peptic ulcers. Antihistamines, on the other hand, are medications that block the action of histamine and are typically used to treat Allergies and motion sickness.
