Can I take Esomeprazole and Vitamin C together?

Why this happens

Vitamin C (ascorbic acid) needs an acidic environment in the stomach to be absorbed most effectively. Esomeprazole works by reducing stomach acid, which can make it slightly harder for the body to take in the vitamin.

You can continue taking both together. If you are concerned about your Vitamin C levels, you can take your Vitamin C supplement at a different time of day than your esomeprazole, or simply ensure you have a diet rich in fruits and vegetables.

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.

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.

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.

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 you are taking esomeprazole to treat.

Caffeine (Coffee, Tea, Energy drinks)

Caffeine can trigger or worsen acid reflux and heartburn symptoms. If you are taking esomeprazole for these conditions, you may find that reducing caffeine intake helps the medicine work more effectively.

Iron-rich foods (e.g., red meat, spinach, fortified cereals)

Vitamin C significantly increases the absorption of iron from plant-based sources (non-heme iron). While often beneficial, patients with conditions like haemochromatosis (iron overload) should be cautious with high doses of Vitamin C.
