Can I take Esomeprazole and Fexofenadine together?

Why this happens

Esomeprazole is a proton pump inhibitor that reduces stomach acid, while fexofenadine is a non-drowsy antihistamine. They are processed by different pathways in the body and do not interfere with each other's absorption, metabolism, or effectiveness.

You can take both medications as prescribed or directed on the packaging. No special precautions are necessary when using them at the same time.

Severe diarrhoea (C. difficile) - esomeprazole

Seek medical help if you develop severe or persistent watery diarrhoea, as this medicine can increase the risk of a serious bowel infection.

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.

Indigestion remedies (antacids)

Do not take indigestion remedies containing aluminium or magnesium within 2 hours of taking fexofenadine. These can lower the amount of medicine your body absorbs.

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.

Alcohol

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.

While fexofenadine is a non-drowsy antihistamine, it is best to avoid or strictly limit alcohol while taking it. Combining the two can increase the risk of side effects like dizziness or sleepiness, and may affect your ability to perform tasks safely.

Grapefruit, orange, and apple juice

Drinking large amounts of fruit juice (especially grapefruit, orange, or apple) can reduce the amount of fexofenadine absorbed by your body, making the medicine less effective. It is best to avoid these juices for a few hours before and after taking your tablet.

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.
