Instant heartburn relief medicine: what to know

Heartburn is a burning feeling behind the breastbone caused when stomach contents move upward and irritate the food pipe. Antacids can act quickly for occasional symptoms. Products containing alginates may form a floating barrier that helps limit upward movement. Acid-reducing medicines are used for symptoms that recur or last longer, but they are not interchangeable and may not give immediate comfort. Read the label, check active ingredients, and tell a pharmacist about regular medicines or kidney problems. Repeated heartburn can occur with acid reflux, gastritis, a hiatus hernia, or a peptic ulcer; the symptom alone cannot identify its cause.

Take only the labelled dose and use the measuring device supplied with liquid medicine. Leave the recommended spacing between an antacid and other tablets because absorption can be affected. Eat smaller meals, avoid lying down soon after eating, and notice whether spicy or fatty foods, coffee, alcohol, or smoking trigger symptoms. Raise the head of the bed if symptoms disturb sleep. A pharmacist can help choose an option for occasional symptoms; ask a clinician if you need medicine repeatedly or symptoms return after stopping it. More detail is available on [Acid Reflux Medication](/treatments/medical-management/acid-reflux-medication/) and [Heartburn](/symptoms/heartburn/).

Seek emergency help for chest pressure, severe breathlessness, fainting, sweating, or pain spreading to the arm, jaw, or back. Arrange prompt medical assessment for vomiting blood, black stools, persistent vomiting, trouble or pain when swallowing, unexplained weight loss, or severe abdominal pain. A new pattern of burning chest discomfort should not be self-treated until a clinician has considered heart and digestive causes.

Ask which product fits your symptoms, how long to try it, whether it interacts with your current medicines, and whether recurring symptoms need testing for reflux or another digestive condition.
