A patient is taking colchicine for the treatment of gout. Due to colchicine's effects on the intestinal mucosa, the patient should be instructed to increase his intake of which vitamin?

Vitamin B12

Explanation

• Colchicine alters the function of the ileal mucosa and interferes with intrinsic factor, causing malabsorption of vitamin B12.

• The patient may need to take vitamin B12 supplements in the form of a sublingual tablet in order to bypass the intestinal tract.
