What is the common side effect of taking butalbital?
Not many other medicines have been able to help, but butalbital does. I would call it about 95% effective, in most of the cases. It works the best when taken at the beginning of pain, but that is not always convenient for me, as this medication makes me quite tired. It is the only side effects which I have felt. I find that if I fall asleep after taking it, I feel much better when I wake-up.
