B12 and Kapidex drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take B12 (cobalamin) and Kapidex (dexlansoprazole). Common drug interactions include spinal disorder among females and chronic kidney disease among males.

The phase IV clinical study analyzes what interactions people have when they take B12 and Kapidex. It is created by eHealthMe based on reports of 25 people who take the same drugs from the FDA, and is updated regularly.

What is B12?

B12 has active ingredients of cobalamin. It is often used in vitamin b12 deficiency. eHealthMe is studying from 121,897 B12 users. Check the latest studies of B12.

What is Kapidex?

Kapidex has active ingredients of dexlansoprazole. It is often used in gastroesophageal reflux disease. eHealthMe is studying from 969 Kapidex users. Check the latest studies of Kapidex.
