Prescription-only medicine. Supplied only if appropriate following an online consultation reviewed by a UK-registered prescriber.
You finish a meal, settle down for the evening and suddenly feel that familiar burning in your chest. Or perhaps you wake up with a sour taste in your mouth and wonder why your stomach is causing so much discomfort.
If this sounds familiar, you may have started looking into acid reflux medicines such as esomeprazole.
Esomeprazole is a medicine that reduces the amount of acid your stomach produces. It is used to treat conditions such as gastro-oesophageal reflux disease (GORD), which can cause heartburn, acid reflux and irritation in the food pipe.
Esomeprazole 20mg may be prescribed when your symptoms need treatment or when reducing stomach acid is part of managing your condition. However, it is not suitable for everyone, and the right treatment depends on your symptoms, medical history and other medicines you may take.
On this page, you can learn how esomeprazole works, what it is used for, how it is normally taken and what to consider before treatment. If you are considering esomeprazole tablets in the UK, you can also find out more about the online consultation process.
A consultation does not automatically mean you will receive a prescription. A UK prescriber must first assess whether the medicine is appropriate for you.
Esomeprazole is the active ingredient in this medicine. It belongs to a group of medicines called proton pump inhibitors, commonly shortened to PPIs.
PPIs work by reducing the amount of acid produced by your stomach. This can help manage symptoms caused by excess stomach acid and give acid-related irritation time to improve.
Esomeprazole is used for several conditions, including:
The medicine may also be used for other purposes under medical supervision.
This product page focuses on esomeprazole 20mg. Your prescriber may recommend a different strength or treatment schedule depending on the condition being treated and your individual circumstances.
One of the main reasons people look for esomeprazole is to manage recurring heartburn or acid reflux.
When stomach acid moves back into the oesophagus, it can cause irritation and a burning sensation. If this happens regularly, it may be linked to GORD.
By reducing stomach acid, esomeprazole can help manage acid-related symptoms and support healing where the oesophagus has been damaged by reflux.
However, not every burning sensation or stomach discomfort is caused by excess acid. This is why a proper assessment matters before choosing treatment.
Your stomach needs acid to help digest food. However, too much acid in the wrong place can cause problems, particularly when it moves into the oesophagus.
Inside the stomach, specialised cells produce acid. Esomeprazole works by blocking a protein in these cells called the proton pump. This reduces the amount of acid released into the stomach.
You do not need to remember the medical details to understand the main point: esomeprazole reduces stomach acid rather than simply neutralising acid that is already there.
This is different from antacids, which neutralise stomach acid and may provide quicker relief for occasional symptoms.
Esomeprazole is generally used as part of a treatment plan when reducing acid production is appropriate. How quickly you notice an improvement can vary, and it may not provide immediate relief from every episode of heartburn.
Your prescriber or pharmacist can explain what to expect based on your symptoms and the treatment you have been advised to use.
Esomeprazole 20mg is a proton pump inhibitor used to reduce stomach acid. It may be prescribed for acid reflux, heartburn and GORD, as well as certain ulcers and other acid-related conditions.
The correct dose and length of treatment depend on why you have been prescribed esomeprazole. Some people need short-term treatment, while others may need longer-term management under medical supervision.
Esomeprazole does not treat every possible cause of chest discomfort, stomach pain or indigestion. If your symptoms are new, severe, persistent or unusual for you, speak to a healthcare professional rather than assuming that acid reflux is the cause.
There are several medicines used to manage heartburn and acid reflux. They work in different ways, so the most suitable option depends on your symptoms and medical needs.
Antacids work by neutralising stomach acid that is already present. They may be useful for occasional symptoms but usually have a shorter effect.
Alginates can form a protective layer over the stomach contents. This may help reduce the amount of reflux moving into the oesophagus.
Proton pump inhibitors, such as esomeprazole and omeprazole, reduce the amount of acid produced by the stomach. They are often considered when symptoms happen regularly or when acid-related irritation needs treatment.
H2-receptor antagonists are another type of medicine that reduces stomach acid. A prescriber may consider them depending on your symptoms, medical history and previous treatment.
These medicines are not interchangeable in every situation. Do not change from one treatment to another, combine medicines or increase your dose without checking with a prescriber or pharmacist.
Your treatment usually begins with a discussion about your symptoms. Your prescriber may ask how often you experience heartburn, whether you have acid coming into your mouth, when symptoms occur and whether they affect your sleep or daily activities.
You may also be asked about other medicines, previous treatments and any medical conditions that could affect your care.
If esomeprazole is considered suitable, your prescriber will decide whether the 20mg strength and recommended treatment period are appropriate.
The medicine may be used to manage symptoms or to help treat irritation caused by stomach acid. Your treatment plan may be different from someone else's, even if you both experience heartburn.
A prescription is only issued when the prescriber considers the treatment appropriate following an assessment.
Your symptoms should be reviewed if they do not improve, return frequently or become worse. You may need further assessment to check whether another condition is contributing to your symptoms.
If you have been taking esomeprazole for a longer period, your healthcare professional may also review whether you still need it and whether your treatment should change.
Do not stop long-term treatment, change your dose or take esomeprazole more often without medical advice. The best approach depends on the reason for treatment and how your body responds.
If your symptoms continue despite treatment, speak to your prescriber instead of simply taking more medicine.
Esomeprazole can be one part of managing acid reflux and related conditions. Your treatment plan may also include changes to eating habits, meal timing, sleeping arrangements and other lifestyle factors.
The medicine reduces stomach acid, but it does not remove every possible trigger for reflux. Keeping track of when symptoms occur can help you and your healthcare professional understand whether your treatment is working as expected.
Esomeprazole can reduce stomach acid, but some everyday habits may also affect how often you experience reflux. Small changes may help you understand and manage your symptoms alongside the treatment recommended by your healthcare professional.
Large meals can increase pressure in your stomach and may make reflux more likely. You may find it helpful to eat smaller meals and avoid eating more than you need.
Try to notice whether particular foods or drinks make your symptoms worse. Common triggers can include fatty foods, spicy meals, coffee, alcohol and chocolate, although triggers vary from person to person.
You do not necessarily need to remove every potential trigger from your diet. Focus on the foods and habits that appear to affect your own symptoms.
Reflux may become more noticeable when you lie down shortly after a meal. If you experience symptoms at night, try to leave some time between your evening meal and going to bed.
Raising the head of your bed may also help some people who experience nighttime reflux. Using extra pillows alone may not provide the same support and can sometimes increase pressure around your stomach.
Smoking, excess weight and certain clothing that puts pressure around the abdomen may contribute to reflux symptoms in some people. If any of these factors apply to you, a healthcare professional can discuss practical changes that may be appropriate.
These adjustments are not a replacement for prescribed treatment, particularly if you have ongoing symptoms or irritation in the oesophagus.
Your prescriber will explain how much esomeprazole to take and how long you should use it. Follow the instructions on your prescription and the medicine packaging.
Esomeprazole is usually taken regularly rather than only when symptoms appear, depending on the reason for treatment. The timing and duration can vary, so do not assume that the instructions for another person will be suitable for you.
Swallow the medicine as directed with water. Do not chew or crush gastro-resistant tablets, as this can affect how the medicine is released. If you have difficulty swallowing tablets, ask your pharmacist or prescriber for advice rather than altering the medicine yourself.
If you forget a dose, follow the instructions in the patient information leaflet or ask a pharmacist what to do. Do not take a double dose to make up for a missed dose unless a healthcare professional has specifically advised you to do so.
If you are looking to buy esomeprazole online in the UK, you will need to complete a clinical assessment before a prescription-only medicine can be supplied.
During the consultation, you may be asked about your symptoms, existing health conditions, allergies and any medicines or supplements you currently use. Answer these questions accurately, including information about treatments you have already tried.
A prescriber will review the information and decide whether esomeprazole is suitable. They may recommend another treatment or advise you to speak to your GP if your symptoms need further investigation.
Completing a consultation does not guarantee that a prescription will be issued. The decision depends on your individual circumstances and the clinical assessment.
Esomeprazole is not suitable for everyone. Tell your prescriber if you have a history of liver problems, allergies to esomeprazole or other medicines, or if you take regular prescription or non-prescription treatments.
It is particularly important to mention medicines that may interact with esomeprazole. Your prescriber will consider your current medicines before deciding whether treatment is appropriate.
You should also seek medical advice if you have warning signs such as unexplained weight loss, difficulty swallowing, repeated vomiting, vomiting blood, black stools or persistent chest pain. These symptoms should not automatically be treated as ordinary acid reflux.
If you experience sudden or severe chest pain, especially with breathlessness, sweating or pain spreading to your arm or jaw, seek urgent medical help.
Like all medicines, esomeprazole can cause side effects, although not everyone will experience them.
Some side effects are mild and may improve as your body gets used to the medicine. Commonly reported side effects can include headache, stomach pain, diarrhoea, constipation, feeling sick, vomiting and wind.
If you notice a side effect that is troublesome, does not go away or is getting worse, speak to your pharmacist or prescriber. They can help you decide whether you should continue treatment or whether another option may be more suitable.
Some symptoms need more urgent attention. Seek medical advice if you develop signs of a serious allergic reaction, such as swelling of the face, lips, tongue or throat, difficulty breathing or a severe skin reaction.
You should also speak to a healthcare professional if you develop severe or persistent diarrhoea, particularly if it occurs with fever or significant abdominal pain.
If you are taking esomeprazole for a long period, your healthcare professional may monitor your treatment from time to time. Long-term use of PPIs can be associated with certain risks, so treatment should be reviewed when appropriate.
Esomeprazole can affect how some medicines work, and some medicines can affect esomeprazole.
Before starting treatment, tell your prescriber or pharmacist about everything you take. This includes prescription medicines, medicines bought from a pharmacy or supermarket, vitamins and herbal products.
Esomeprazole and Mounjaro (tirzepatide) are different medicines used for different purposes, and they may sometimes be prescribed at the same time.
Mounjaro can affect how quickly food leaves the stomach. Some people taking it experience nausea, indigestion, burping or reflux symptoms. If you already experience acid reflux, it is worth telling your prescriber, particularly if your symptoms change after starting Mounjaro.
Your healthcare professional can check your medicines together and decide whether esomeprazole is appropriate for you.
Do not start, stop or change either medicine simply because you have read that they can be used together. Your treatment should be based on your own medical history and the reason each medicine has been prescribed.
If you are pregnant, planning to become pregnant or breastfeeding, tell your prescriber before taking esomeprazole.
Heartburn and acid reflux can be common during pregnancy, but not every medicine is suitable for use during pregnancy. Your healthcare professional can help you choose an appropriate treatment based on your symptoms and circumstances.
If you are breastfeeding, ask your doctor or pharmacist whether esomeprazole is appropriate for you. They can take your treatment needs and the available safety information into account.
Esomeprazole is not designed to provide instant relief in the same way as some antacids.
It reduces the amount of acid your stomach produces, so it may take some time before you notice the full effect. Some people start to feel better within a few days, while symptoms caused by irritation of the oesophagus may take longer to settle.
If you have been taking esomeprazole as prescribed but your symptoms are not improving, speak to your prescriber or pharmacist.
Do not simply increase the dose or take extra tablets because you are still experiencing symptoms.
If your symptoms continue despite treatment, it does not necessarily mean that you need a stronger dose.
There are several possible reasons why reflux symptoms may continue. The medicine may not be the right treatment for the cause of your symptoms, you may have another condition causing similar symptoms, or lifestyle factors may still be contributing to reflux.
Your prescriber may review your symptoms, check how you are taking the medicine and decide whether you need further assessment.
Persistent symptoms should not be managed by repeatedly increasing your medicine without medical advice.
If you have been taking esomeprazole for a longer period, do not stop treatment suddenly without discussing it with your healthcare professional.
When stomach acid has been suppressed for some time, stopping a PPI can sometimes cause a temporary increase in acid-related symptoms. This is sometimes called rebound acid secretion.
Whether you should stop, reduce or continue treatment depends on why you were prescribed esomeprazole and how long you have been taking it.
Your prescriber can advise you on the most appropriate way to change your treatment.
Occasional heartburn is common, but ongoing symptoms should not always be treated as a simple acid problem.
Speak to your GP or another healthcare professional if your symptoms keep coming back, do not improve with treatment or are affecting your sleep and daily life.
Sudden or severe chest pain, particularly when accompanied by breathlessness, sweating, dizziness or pain spreading to the arm, jaw, neck or back, needs urgent medical attention.
Esomeprazole 20mg is a proton pump inhibitor that reduces the amount of acid produced by the stomach. It is commonly used for acid reflux, GORD and other acid-related conditions.
It is usually taken regularly according to the treatment plan rather than only when symptoms appear. The right dose and treatment length depend on the condition being treated.
Esomeprazole can be an effective part of managing acid-related symptoms, but it is not suitable for every person or every type of digestive problem. Your symptoms, medical history and other medicines should be considered before treatment.

The appropriate dose depends on the condition being treated, so some people may be prescribed a different strength or treatment schedule.
They are not automatically interchangeable. If you are considering changing from one to the other, speak to your prescriber or pharmacist.
The appropriate medicine and dose depend on your condition, symptoms, other medicines and how you respond to treatment. Your prescriber can recommend the option that is appropriate for you.
How often you should take it and how long you should continue depends on the reason for treatment. Follow the instructions on your prescription and speak to your healthcare professional before making changes.
However, it is not intended to treat every type of chest discomfort. If you have new, severe or unusual chest pain, do not assume that it is heartburn. Seek appropriate medical advice.
The right approach depends on why you are taking esomeprazole and how often you experience symptoms.
If you notice that alcohol triggers your heartburn or acid reflux, reducing your intake may help. If you are taking other medicines as well, check with a pharmacist because alcohol can interact with some medicines or make certain side effects more noticeable.
Unexplained weight loss is more important to discuss promptly, particularly if you also have ongoing reflux, difficulty swallowing or persistent digestive symptoms.
If diarrhoea is severe, persistent or accompanied by fever or significant abdominal pain, seek medical advice. Do not assume that ongoing digestive symptoms are simply a normal side effect.
If it is nearly time for your next dose, you may be advised to skip the missed dose and continue as normal.
Do not take two doses together to make up for a missed dose unless your healthcare professional has specifically told you to do so.
Because this is a prescription-only medicine, a UK-registered prescriber must decide whether it is suitable for you before it can be supplied.
If you use an online pharmacy, check that it is properly registered and that you understand who is responsible for prescribing and dispensing your medicine.
If you are obtaining esomeprazole through an online pharmacy, you will normally need to complete a clinical assessment before a prescription-only product can be supplied.
