Heartburn, or acid indigestion, is a common condition that affects millions of people. Most people describe heartburn as a burning or painful feeling in the chest. Heartburn can last for a few minutes or for hours and often strikes after a meal or at night, when lying down. Taking Gaviscon can help stop acid breakthrough fast. Gaviscon’s fast foaming action works within seconds of taking it. The smooth & creamy formula forms a protective acid barrier to keep acid down for hours. If reflux occurs, the foam barrier will protect against breakthrough and help to prevent heartburn. Whatever treatment your healthcare professional recommends or prescribes, be sure to follow some simple precautions. Read all medication labels carefully, and check with your doctor or pharmacist before combining any prescription or non-prescription drugs.
