It will be fine. My doctor used to prescribe me a vial of cyanocobalamin to give myself injections at home. The vial lasted a good 6 months and remained potent at room temperature. I now take my dosage in liquid form sublingually with a dropper, 5000mcg a day. It is just as effective as the injections. You might want to consider this way of ingesting it. "G"
