Acid Reflux

Shop acid reflux and heartburn relief products from a UK based and regulated pharmacy. Orders are sent by Royal Mail in discreet packaging, with free delivery on orders over £20. This collection brings together over-the-counter options you can use as directed for short-term symptom relief—whether discomfort flares after meals, when bending, or overnight.

Most options fit into three practical groups: antacids for quick, temporary relief, alginate-style products that may help reduce reflux backflow after meals or at bedtime, and reflux control (PPI) tablets for adults where suitable (short-course use only). Always check age limits, warnings, interactions and maximum treatment duration on the pack, and ask a pharmacist if symptoms keep returning.

Popular types of acid reflux products

  • Soft chew antacids (easy-to-take chews for temporary relief)
  • Antacid liquids and suspensions (a liquid format some people find easier to take)
  • Chewable antacid tablets often chosen for quick, occasional symptoms
  • Salts, powders or sachets mixed with water for occasional indigestion/heartburn support as directed
  • Reflux control tablets for adults (PPIs for short-term treatment where suitable)

How to choose the right option

  • Start with when it happens: after-meal or night-time reflux may suit an alginate-style option; occasional daytime symptoms may suit an antacid chew, tablet or liquid.
  • Check who it’s for: guidance can differ for children, pregnancy/breastfeeding and certain health conditions—follow the label carefully.
  • Review your medicines: antacids can affect absorption of some medicines, so follow spacing advice and ask a pharmacist if you take prescriptions.
  • Avoid doubling up: don’t combine products with similar active ingredients unless the leaflet says it’s appropriate.
  • Use the correct duration: reflux control tablets are intended as a short course for adults—don’t exceed the stated treatment length.
  • Escalate when needed: frequent, persistent or worsening symptoms should be reviewed by a pharmacist or GP.

FAQs

What’s the difference between acid reflux and heartburn?

Acid reflux is when stomach contents flow back towards the oesophagus. Heartburn is the burning sensation this can cause. Symptoms are often worse shortly after eating, when lying down, or when bending forward.

Which product type is usually chosen for fast, occasional relief?

For occasional symptoms, many people start with an antacid chew, tablet or liquid for quick, temporary relief. If reflux backflow after meals or at night is a main issue, an alginate-style product may be worth considering, following pack directions.

How long can I take reflux control tablets such as omeprazole or esomeprazole for?

Over-the-counter reflux control (PPI) tablets are usually intended for adults as a short course. Always follow the patient leaflet for the maximum treatment duration, and seek advice from a pharmacist or GP if symptoms continue or keep returning.

Can acid reflux be linked to a cough or sore throat?

Reflux can sometimes be associated with throat irritation, hoarseness or a cough. If these symptoms are new, persistent, worsening, or you’re unsure of the cause, it’s best to speak to a pharmacist or GP for tailored advice.

How often is “too often” for heartburn or reflux?

If symptoms are frequent, persistent, changing, or you find you’re repeatedly self-treating, it’s best to speak to a pharmacist or GP to check the cause and the safest next step.

What about acid reflux during pregnancy or breastfeeding?

Heartburn can be common in pregnancy, but not every product is suitable. Check the label carefully and speak to a pharmacist or GP before choosing medicines during pregnancy or while breastfeeding.

When should I seek urgent medical advice?

Seek urgent help if you have chest pain, difficulty swallowing, persistent vomiting, vomiting blood, black stools, unexplained weight loss, or severe/worsening symptoms. If symptoms are frequent or persistent despite correct short-term use, speak to a pharmacist or your GP.

Important: This information supports responsible self-care and does not replace medical advice. Always read the label and patient leaflet, follow dose and duration guidance, and check suitability if you are pregnant or breastfeeding, buying for a child, or taking other medicines. If symptoms are persistent, unusual or worsening, speak to a pharmacist or GP. In an emergency, call 999 or attend A&E.
