Can I take Omeprazole and Vitamin B12 together?

لماذا يحدث هذا

Vitamin B12 is naturally bound to proteins in food. To release the vitamin so your body can use it, you need stomach acid. Omeprazole works by reducing the amount of acid your stomach produces. With less acid available, the B12 stays 'locked' in the food and passes through your system without being fully absorbed.

If you take omeprazole for more than 2 to 3 years, ask your doctor to check your vitamin B12 levels with a blood test. You should also watch for signs of low B12, such as feeling very tired, having a sore tongue, or feeling 'pins and needles'. If you need a supplement, high-dose oral tablets or B12 injections usually work well because they don't rely as much on stomach acid for absorption.

Vitamin B12 deficiency

Long-term use of omeprazole can prevent your body from absorbing Vitamin B12 properly, which may lead to nerve damage or anaemia.

إسهال شديد

Contact your doctor immediately if you develop severe or persistent watery diarrhoea, as omeprazole can increase the risk of a serious bowel infection called Clostridium difficile.

Lupus (SLE)

Seek medical advice if you develop a skin rash, especially in areas exposed to the sun, as omeprazole can trigger or worsen a rare autoimmune condition called Subacute Cutaneous Lupus Erythematosus.

الكحول

It is best to avoid or strictly limit alcohol while taking omeprazole. Alcohol can increase the amount of acid your stomach produces, which may worsen your symptoms or make the medicine less effective. Additionally, both alcohol and omeprazole can irritate the stomach lining.

It is best to avoid or strictly limit alcohol while taking Vitamin B12. Heavy alcohol consumption can interfere with the body's ability to absorb Vitamin B12 from the gut and can reduce the amount of the vitamin stored in the liver.

General Food Timing

Omeprazole works best if you take it 30 to 60 minutes before a meal, preferably breakfast. Taking it with food can slow down how quickly the medicine starts to work.
