Will Fioricet help back pain?

Yes, it may as it contains butalbital, which is a mild narcotic. It is not as effective as other pain medications, but at my job as a neurologic assistant, I see many patients that have told me it improves their back pain. But as Robert said, it is indicated for headaches.

I have not heard of this medicine, so I'm sorry I can't answer your question. Just
Google that name in tho, and you will get a lot o information about it.

It may but fiorinal is most often used for treating headaches.
