What should you know about prescribed heartburn medicine?

A clinician may prescribe an acid-reducing medicine when burning behind the breastbone is frequent, persistent, or interfering with sleep. Different medicines work in different ways: some neutralise acid already present, while others reduce acid production for longer. Treatment may be used for acid reflux, irritation of the stomach lining, or an ulcer, but heartburn can have several causes. A hiatus hernia can make reflux easier, and excess weight may increase pressure on the stomach.

Follow the label for timing and dose, and do not stop a regular course suddenly without checking with the prescriber. Tell the clinician or pharmacist about every medicine, supplement, and painkiller you use, because some combinations need spacing or review. Smaller meals, avoiding lying down soon after eating, and identifying personal trigger foods may support symptom control. Keep a note of breakthrough symptoms, swallowing discomfort, and any unwanted effects. Do not keep treating recurring symptoms yourself without reassessment; gastritis and peptic ulcer disease may need a different plan.

Arrange medical review if symptoms continue despite the prescription, return soon after treatment, or come with repeated vomiting, difficulty swallowing, unexplained weight loss, or black stools. Seek urgent help for severe chest pressure, breathlessness, fainting, or pain spreading to the arm or jaw, because these symptoms can have causes unrelated to reflux.

Ask what the medicine is treating, when it should be taken in relation to meals, how long the planned course lasts, and what to do if a dose is missed. You can also ask whether another condition, such as [Gastritis](/conditions/gastritis/), needs assessment.
