Cats with inflammatory bowel disease (IBD) are at risk for vitamin B12 deficiency because chronic inflammation caused by IBD interferes with and may completely block absorption of vitamin B12 in the intestines. Vitamin B12 injections are administered subcutaneously (under the skin), and can be given up to once weekly. Vitamin B12 is water soluble, so it is a very safe medication. We have seen significant improvements with many cats that have chronic gastrointestinal problems or pancreatitis.
This injectable vitamin B12 is 3000 mcg/ml and includes syringes and needles.
