Overview

Persistent heartburn or acid reflux can wear you down — turning meals into worry, nights into discomfort, and everyday life into a battle with burning pain. Esomeprazole is a trusted treatment designed to give you lasting relief by targeting the root cause: excess stomach acid. By calming acid production, it helps soothe irritation, protect your oesophagus, and restore comfort so you can eat, sleep, and live without constant disruption.


At SwiftMedi, your order will always be reviewed by a UK-registered prescriber after a secure online consultation, with discreet next-day delivery available.


What is Esomeprazole


Esomeprazole is a medicine from the group known as proton pump inhibitors (PPIs). It works by blocking the acid pumps in the stomach, reducing the amount of acid produced and helping to protect the stomach lining. By lowering stomach acid, it also allows the oesophagus (food pipe) to heal if it has been irritated by reflux.

Esomeprazole is commonly prescribed for frequent heartburn, acid reflux and gastro-oesophageal reflux disease (GORD), as well as for the treatment and prevention of stomach and duodenal ulcers. It is also used to help protect against acid-related problems in people taking long-term NSAIDs.

Many patients experience fast and long-lasting relief, often noticing improvements within just a few days of starting treatment, making esomeprazole a trusted option for ongoing acid control.

Directions

  • Esomeprazole is usually taken once daily (morning is best), with or without food.
  • Tablets should be swallowed whole with water — do not chew or crush.
  • Typical dose: 20mg to 40mg daily, depending on severity and prescriber advice.
  • For GORD, treatment may be needed for 4–8 weeks. Some people may require longer-term use under medical guidance.


Always follow the exact instructions given by your prescriber.

Side Effects

Like all medicines, esomeprazole can cause side effects, although not everyone will experience them. Most are mild, short-lived, and improve as your body adjusts to treatment.

Common (may affect up to 1 in 10 people):

  • Headache – usually mild and temporary.
  • Stomach pain, constipation, diarrhoea, or nausea – digestive upset is among the most common effects but is generally mild.
  • Bloating or wind (flatulence) – some people may experience discomfort from excess gas.


Uncommon (may affect up to 1 in 100 people):

  • Dizziness or tiredness – may affect alertness; avoid driving or operating machinery if you feel unwell.
  • Dry mouth – usually mild and temporary.
  • Swelling of ankles or feet (oedema) – caused by fluid retention in some patients.


Rare but serious (seek urgent medical advice):

  • Severe allergic reaction (anaphylaxis) – symptoms include swelling of the face, lips, tongue, or throat, difficulty breathing, or a sudden rash.
  • Severe stomach pain or persistent vomiting – may indicate bleeding or complications from ulcers.
  • Signs of liver problems (jaundice) – yellowing of the skin or eyes, dark urine, or persistent tiredness.


Most people tolerate esomeprazole well, and side effects (if they do occur) are usually mild. If you are concerned about any symptoms, or if they do not improve, speak to your doctor, pharmacist, or prescriber.

 Disclaimer: This is not a complete list of side effects. Always read the patient information leaflet provided with your medicine for full details. If you experience severe or worrying symptoms, seek medical advice straight away. In an emergency, call 999 or go to A&E.
