Can I take Esomeprazole and Indapamide together?

Why this happens

Indapamide is a 'water pill' (diuretic) that helps your body get rid of excess salt and water, but it also causes you to lose potassium and magnesium through your urine. Esomeprazole is a proton pump inhibitor (PPI) that can reduce the amount of magnesium your body absorbs from food. When used together, these effects can add up, leading to a deficiency.

What you should do

You can take these medicines together, but your doctor may want to monitor your mineral levels with occasional blood tests. If you experience unusual muscle weakness, spasms, or a fluttering feeling in your chest (palpitations), you should contact your doctor. Do not stop taking your medication without speaking to a healthcare professional first.

Important precautions

Sulphonamide allergy

Do not take this medicine if you have a known allergy to sulphonamide antibiotics (such as sulfamethoxazole), as you may have a similar allergic reaction to indapamide.

Low potassium (Hypokalaemia)

Indapamide lowers potassium levels in your blood. You must have regular blood tests, as low potassium can cause serious heart rhythm problems, especially if you also take digoxin.

Vitamin B12 deficiency and bone fractures - esomeprazole

Long-term use (over a year) can weaken bones and lead to low magnesium or B12 levels; your doctor should monitor these if you are on long-term treatment.

Severe kidney or liver disease

Your doctor may need to prescribe a lower dose, as your body will take longer to clear esomeprazole.

Severe diarrhoea

If you develop severe, watery, or persistent diarrhoea, contact your doctor immediately. Esomeprazole can increase your risk of a serious bowel infection called Clostridium difficile.

Magnesium deficiency

Taking esomeprazole for more than three months can cause your blood magnesium levels to drop significantly, leading to fatigue, muscle spasms, or dizziness.

Masking stomach cancer symptoms

Esomeprazole can hide the symptoms of stomach cancer. You must tell your doctor if you have unexplained weight loss, persistent vomiting, or difficulty swallowing before starting this medicine.

Food and drink warnings

Alcohol

Drinking alcohol while taking indapamide may increase the medicine's blood-pressure-lowering effect. This can make you feel dizzy, lightheaded, or faint, especially when standing up quickly. It is best to keep your alcohol intake within recommended limits and see how the medicine affects you before drinking.

While alcohol does not directly interact with esomeprazole, it can increase stomach acid production and irritate the stomach lining, which may worsen the symptoms your medicine is intended to treat. It is best to limit alcohol intake.

Caffeine

Caffeine (found in coffee, tea, and some fizzy drinks) can trigger or worsen acid reflux and heartburn. This may make esomeprazole less effective at managing your symptoms.

Salt (Sodium)

Eating a diet very high in salt can make indapamide less effective at lowering your blood pressure. Try to avoid adding extra salt to your food.
