Esomeprazole is a medicine used to treat acid reflux, heartburn and indigestion or to prevent stomach ulcers. It is sometimes taken for a rare condition called Zollinger-Ellison syndrome.
Esomeprazole belongs to a drug class called proton pump inhibitors. It is also available as a branded product called Nexium. The full name of the drug is esomeprazole magnesium.
Esomeprazole acid reflux tablets work by blocking the action of the proton pump in the stomach. This means that your stomach produces less acid, which is what causes a burning feeling in the chest, or regurgitation when it backs up into the oesophagus.
The dose of esomeprazole used to treat acid reflux is 20mg once daily. You may take esomeprazole long term if you have chronic acid reflux, however, you will require a prescription from your doctor.
Please note: You should not take esomeprazole for more than 14 days unless your doctor has advised you to. If your symptoms do not improve or get worse, you should speak to your doctor as you may need to have tests carried out, such as a gastroscopy.
You should take one tablet around 30-60 minutes before breakfast. The best time to take esomeprazole is in the morning. You should sit upright when taking a tablet and swallow it whole with a glass of water. If you are unable to swallow tablets, you can crush the tablet and dissolve it in water.
If you miss a dose of esomeprazole, you should take a tablet as soon as you remember. If it is close to the time of your next dose, skip the missed dose and go back to your normal regimen. Do not take 2 doses at the same time or extra doses to make up for the missed dose.
It can take around 2-3 days for the effects of esomeprazole to kick in. However, you should give it around a month for the full effect to be seen. If you do not feel better after 14 days, you should see your doctor.
