There are several medications that can interfere with how well your body absorbs vitamin B12, possibly increasing your risk of vitamin B12 deficiency. Among the drugs that may reduce your body's level of vitamin B12 are medicines used to lower cholesterol, treat ulcers, decrease stomach acid, reduce risk of seizures and treat cancer and diabetes.
Certain antibiotics (including tetracycline), if taken at the same time as vitamin B12 supplements, may decrease your body's absorption of vitamin B12. The supplement may also decrease your body's absorption of the antibiotic, making it less effective. Taking the antibiotic and the supplement at separate times of the day may lessen these interactions. Talk to your doctor before taking vitamin B12 supplements or any dietary supplement. Always be sure that your doctor is aware of all of the medications and supplements you take.
