Nexium (Esomeprazole UK) x14 Tablets

Description

Nexium is the brand name for esomeprazole magnesium, a proton pump inhibitor (PPI) that reduces stomach acid. It’s a refined version of omeprazole (Prilosec) and is often considered more effective in some patients due to better absorption.

2. What Is Nexium Used For?

Gastroesophageal Reflux Disease (GERD):

Treats symptoms like heartburn and acid regurgitation.

Helps heal erosive esophagitis (damage to the esophagus caused by acid).

Stomach and Duodenal Ulcers:

Especially those caused by H. pylori (used alongside antibiotics).

Zollinger-Ellison Syndrome:

A rare condition where the stomach produces too much acid.

NSAID-related ulcer prevention:

For people taking long-term NSAIDs like ibuprofen who are at risk of ulcers.

3. How Nexium Works

It blocks the H+/K+ ATPase enzyme (also called the “proton pump”) in the stomach lining, which reduces acid secretion. This allows damaged tissue to heal and prevents further irritation.

4. Dosage and Administration

Typical doses:

20 mg or 40 mg once daily.

Some conditions may require twice-daily dosing.

When to take:

At least 1 hour before meals (usually breakfast).

5. Side Effects

Common:

Headache

Nausea

Abdominal pain

Less common but serious:

Vitamin B12 deficiency (with long-term use)

Magnesium deficiency (can cause muscle spasms or irregular heartbeat)

Increased risk of bone fractures (hip, wrist, spine)

Kidney problems (rare but possible)

C. difficile infection (from disrupted gut bacteria)

6. Drug Interactions

Clopidogrel (Plavix): Nexium may reduce its effectiveness.
