What Is Nexium Used For?

Nexium is a proton-pump inhibitor that reduces the amount of acid your stomach produces. This helps relieve symptoms and allows healing to occur while maintaining normal food digestion.

Primary Uses

Nexium treats reflux oesophagitis (heartburn caused by stomach acid backing up into the food pipe), upper stomach symptoms from NSAID pain medications, peptic ulcers associated with Helicobacter pylori bacteria, the rare Zollinger-Ellison syndrome where the stomach produces excessive acid, and bleeding peptic ulcers.

How It Works

Nexium works by decreasing the amount of acid made by the stomach, providing symptom relief and allowing healing to take place. This does not interfere with normal food digestion.

Good to know: There is no evidence that Nexium is addictive.

How to Take Nexium

Nexium should be taken at about the same time each day to help you remember. It can be taken with food or on an empty stomach.

Dosage Instructions

Tablets: Usually 20 mg or 40 mg once daily. Swallow whole with water – do not crush or chew. If you have trouble swallowing, dissolve in half a glass of non-carbonated water, stir gently, and drink within 30 minutes. Granules: Usually 10-20 mg daily. Empty sachet contents into appropriate amount of water (15 mL for 10 mg, 30 mL for 20 mg), stir, let thicken, stir again, and drink within 30 minutes.

What If You Miss a Dose?

Take the missed dose as soon as you remember, then return to your normal schedule. If it’s almost time for your next dose, skip the missed dose and continue as usual.

Important: Never take a double dose to make up for a missed dose.
