Phazyme is used to relieve symptoms of excess gas including bloating, feelings of fullness, pressure, and stomach discomfort. It may be helpful for those experiencing gas from dietary choices (such as beans, cabbage, or carbonated beverages), digestive conditions, or post-operative gas buildup.
Phazyme contains simethicone, an antiflatulent agent that works by reducing the surface tension of gas bubbles in the digestive tract. This allows smaller bubbles to combine into larger ones, making them easier to pass through belching or flatulence and providing relief from associated discomfort.
Phazyme is generally well-tolerated with no known drug interactions. It may reduce absorption of certain oral medications if taken simultaneously—space doses at least 2 hours apart. Not intended for infant colic without medical supervision. Consult a healthcare provider if symptoms persist beyond 2 weeks or are accompanied by severe abdominal pain.
