Unfortunately YES. You can be dependency on Fioricet.
The reason for this is that one of the ingredients in Fioricet is butalbital. Barbiturate have been known to cause dependency if they are used for longer periods of time.
If you use Fioricet for longer periods of time, you may develop dependency to it. Luckily, your doctor can help you discontinue the drug without experiencing withdrawal symptoms by slowly tapering down the drug.
The best way to avoid becoming dependency on Fioricet is to only take the medication as prescribed.
If you start to notice that Fioricet is getting less effective at treating your headaches, talk to your doctor about alternative options.
