I am also wondering about the new higher ph, sharper needle formula. I have heard about it but have not been able to find out when it might be available. I will check with the pharmacy and see. I just got a new months supply and looked all through the patient insert stuff but found no mention of new and improved. I will have been on rebif for a year this January and while each injection seems different (a place hurts one time but not the next) it does seem that my body is tolerating it better. Also, I read something about a new autoinjector that will allow you to adjust the needle depth which I would give me more places to inject ( that don't have as much fat). I have seen a picture of it, I believe it may be available in the UK.
