Different medications for
GERD work in different ways. Your doctor may prescribe a combination of over the counter and prescription medications to help treat and control your GERD.
Proton Pump Inhibitors
H-2 Blockers CimetidineFamotidineNizatidineRanitidine
Antacids Alka-SeltzerMaalox Advanced Regular StrengthPepto-BismolTumsRolaidsMylanta
Common brand names include: OmeprazoleLansoprazolePantoprazoleRabeprazoleEsomeprazoleDexlansoprazole
PPIs block stomach acid production created by the stomach’s acid-making cells. By greatly decreasing the amount of stomach acid, PPIs reduce the symptoms of GERD and help prevent damage that occurs from acid reflux into the esophagus.
Side effects may include: DiarrheaConstipationStomach painNausea or vomitingHeadacheIncreased risk of fracture in older adults, especially in people who take PPIs in high doses for longer than a year
Common brand names include: CimetidineFamotidineNizatidineRanitidine
H-2 blockers decrease the amount of acid secreted by the stomach by blocking histamine release. This decrease in stomach acid reduces the symptoms of GERD and helps prevent damage to the esophagus that acid reflux can cause.
Side effects may include: HeadacheDiarrheaNauseaDrowsinessConfusion
Common brand names include: Alka-SeltzerMaalox Advanced Regular StrengthPepto-BismolTumsRolaidsMylanta
Antacids are a combination of 3 basic salts—magnesium, calcium, and aluminum—combined with hydroxide or bicarbonate ions. Antacids come in chewable tablet and liquid forms. Antacids help control the symptoms of GERD by
neutralizing stomach acid.
Side effects may include: Diarrhea or constipationHigh blood levels of calcium
(if the antacid contains calcium)
or other kidney problems
Common brand names include: BethanecholMetoclopramide
Prokinetics help control acid reflux by strengthening the lower esophageal sphincter muscle and/or
emptying the contents of the stomach faster. This shortens the time during which reflux can occur. Prokinetics are usually given along with other GERD medications.
Side effects may include: DrowsinessRestlessnessDiarrheaNausea
