The reason I'm asking about
antihistamines is because I read the below show article and my sister who was diagnosed with GERD finds much relief when she takes Zyrtec. I know it's weird.
Antihistamines are also used to treat acid reflux. Stomach walls produce histamine. Histamine accelerates acid production by binding specific receptors present on acid producing cells of stomach. Antihistamine drugs bind to these receptors and block histamine binding that in turn reduces the acid production. Ranitidine, Famotidine, Cimetidine and Nizatidine are commonly used antihistamines or histamine antagonists. They are available without prescription as over-the-counter (OTC) but the dose of OTC is lower than those available by prescription. Antihistamine drugs are taken 30 minutes earlier than meal. This will make antihistamine available in higher concentration when stomach is actively producing acids to digest food. Antihistamine gives fast relief from primary heartburn and inflammation of esophagus.
