For quick relief from severe acidity and stomach pain, a liquid antacid containing a combination of aluminum hydroxide, magnesium hydroxide, and simethicone is highly effective. Liquid formulations work faster than tablets because they quickly coat the stomach lining, neutralizing acid and breaking up painful gas bubbles. For sharper pain, an antacid containing oxetacaine (a local anesthetic) can temporarily numb the stomach lining to provide rapid relief. Please follow the package instructions for dosage. If your pain is unusually severe, persistent, or accompanied by vomiting, it is important to consult a doctor to rule out other conditions.
