Hi and Welcome- Yes, Fioricet can lead to physical dependence and addiction at the dose you're taking; especially taking it every day.
Only take it when you absolutely need it and do read the drug info that came with this RX, as Openmind suggested. Fioricet can and does cause rebound headaches and shouldn't be abruptly stopped. I don't think stopping after one week would be problematic but taper off to be safe. Good luck!
It contains a barbiturate. It causes psychological dependence, and physical dependence if taken long enough. It's not to be stopped suddenly. If and when you want to stop it you'll need to do a long slow and gradual taper program. When you get your scripts you should have an info sheet that goes along with it. I hope the prescription helps you with your headache pain. Those can be really rough. I wish you the best.
