What you should know while taking Fioricet if you are a senior
For butalbital: Certain side effects, such as confusion, excitement, or mental depression, may be especially likely to occur in elderly patients, who are usually more sensitive than younger adults to the effects of the butalbital in this combination medicine.
For acetaminophen: Acetaminophen has been tested and has not been shown to cause different side effects or problems in older people than it does in younger adults.
For caffeine: Many medicines have not been studied specifically in older people. Therefore, it may not be known whether they work exactly the same way they do in younger adults or if they cause different side effects or problems in older people. There is no specific information comparing use of caffeine in the elderly with use in other age groups.
