I am prescribed .25mg (very low dose) of xanax (alprozolam) for anxiety. From many of the posts I have read, it has been said that xanax is a terrible long term drug. I only take .25mg of the drug maybe twice a week at the most sometimes going for months without it because i only take it as needed. at this rate will my body build a tolerance to the drug? I really want to continue to use the drug as needed in the long term (years), considering how little I take xanax is this okay to use for many years to come or should I look into switching medications?
