There is no maximum time you can stay on prednisone but it's recommended that if you are declared prednisone dependent and all other medical options have failed, that you consider surgery. The problem wiht prednisone is that the longer you are on it the more potential for developing long lasting side effects. Often the damage that prednisone causes is not realized until one is successfully weaned from it. In that now is not a good time to consider surgery you might want to do a couple of things to protect yourself. First, try to get down to the lowest dose that will keep you from flaring. Ideally that would be below 10mg. The other thing you can do to help yourself is engage in regular weight bearing exercise. Whether that's regular walking or lifting weights, you need to protect your bones. Also, you might consider taking calcium citrate.
