What is Esomeprazole?

Esomeprazole is a medication that is used to treat acid reflux and other conditions caused by excess stomach acid, like gastro-oesophageal reflux disease. Like other medications used to treat acid reflux, Esomeprazole is a proton pump inhibitor. Esomeprazole is the generic version of the brand-name drug Nexium. Esomeprazole is a cheaper version of Nexium tablets.

How does Esomeprazole work?

Esomeprazole contains the active ingredient esomeprazole. It belongs to a group of medicines known as proton pump inhibitors (PPIs). PPIs limit the amount of acid produced in the stomach. This then reduces the amount of acid that travels up the oesophagus and causes the symptoms associated with acid reflux. Esomeprazole is a reliable Nexium alternative.

How do you take Esomeprazole?

Always take this medication as it has been prescribed to you by your doctor or pharmacist. If you are taking this medication for a long period of time, your doctor will want to monitor you. If you have been instructed to take this medication as and when you need it, tell your doctor if your symptoms change.


The typical dose of this medication is one tablet daily, preferably at the same time each morning. Esomeprazole can be taken with or without food. Do not exceed more than directed.

How effective is Esomeprazole in treating acid reflux?

Esomeprazole, like other proton pump inhibitors (PPIs) is an effective way of managing acid reflux. In addition to taking Esomeprazole, there are some lifestyle factors worth considering when suffering from acid reflux. These include:

  • avoiding spicy or fatty foods
  • quitting smoking
  • losing weight

It is worth considering taking these additional measures to limit the occurrence of acid reflux.

What are the most common side effects of Esomeprazole?

Like all medicines, this medicine can cause side effects. However, not everyone will experience side effects. Side effects of Esomeprazole are usually mild to moderate and only last for a short period of time.


The most common side effects of Esomeprazole are:

  • Headaches
  • Stomach aches, diarrhoea, constipation, flatulence
