What should you know about types of acid reflux medicine?

Antacids neutralise acid already in the stomach and may help occasional symptoms quickly. Alginates form a floating barrier that can reduce reflux after meals. H2 blockers reduce acid production for a longer period. Proton pump inhibitors reduce acid production more strongly and are often used when symptoms are frequent or the oesophagus needs time to heal. The right choice depends on symptom pattern, other medicines, pregnancy, and health conditions. [Acid Reflux](/conditions/acid-reflux/) can also be associated with a [Hiatus Hernia](/conditions/hiatus-hernia/).

Follow the product instructions or your prescriber’s directions, including whether a medicine should be taken before food or only when symptoms occur. Do not combine several acid medicines routinely without checking with a pharmacist or clinician. Review treatment if symptoms continue, return soon after stopping, or interfere with sleep. Smaller meals, avoiding personal triggers, and allowing time between eating and lying down may also help. Reflux can sometimes contribute to [Cough](/symptoms/cough/) or [Difficulty Sleeping](/symptoms/difficulty-sleeping/).

Arrange medical assessment for trouble swallowing, food sticking, repeated vomiting, unexplained weight loss, black stools, or vomiting blood. Do not assume new [Chest Tightness](/symptoms/chest-tightness/) is reflux: sudden, severe, or exertional chest symptoms need urgent assessment. Persistent [Abdominal Pain](/symptoms/abdominal-pain/) also deserves review, particularly if it is worsening or accompanied by fever.

Ask which medicine fits your symptom pattern, how long to try it, when to take it, which interactions matter, and how to step down or stop treatment safely.
