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)Kidney stones
or other kidney problems
Common brand names include: BethanecholMetoclopramide
Prokinetics help control acid reflux by strengthening the lower esophageal sphincter muscle and/or
