How should I take Fioricet?

Take Fioricet exactly as prescribed. Follow all directions on your prescription label.

Do not take more of this medication than recommended. An overdose can damage your liver or cause death. Tell your doctor if the medicine seems to stop working as well in relieving your pain.

Butalbital may be habit-forming. Never share Fioricet with another person, especially someone with a history of drug abuse or addiction. Keep the medication in a place where others cannot get to it. Selling or giving away Fioricet is against the law.

Take Fioricet with food or milk if it upsets your stomach.

Store Fioricet at room temperature away from moisture and heat.

Keep track of the amount of medicine used from each new bottle. Butalbital is a drug of abuse and you should be aware if anyone is using your medicine improperly or without a prescription.

What should I avoid while taking Fioricet?

This medication can cause side effects that may impair your thinking or reactions.

Be careful if you drive or do anything that requires you to be awake and alert.

Avoid drinking alcohol.  It may increase your risk of liver damage while taking acetaminophen.

Ask a doctor or pharmacist before using any other cold, allergy, pain, or sleep medication. Acetaminophen (sometimes abbreviated as APAP) is contained in many combination medicines.

Taking certain products together can cause you to get too much acetaminophen which can lead to a fatal overdose. Check the label to see if a medicine contains acetaminophen or APAP.

While you are taking this medication, avoid taking diet pills, caffeine pills, or other stimulants (such as ADHD medications) without your doctor’s advice.

Before taking Fioricet

Do not use Fioricet if you have taken an MAO inhibitor in the past 14 days. A dangerous drug interaction could occur. MAO inhibitors include isocarboxazid, linezolid, phenelzine, rasagiline, selegiline, and tranylcypromine.

You should not use Fioricet if you are allergic to acetaminophen, butalbital, or caffeine, if you have porphyria, or if you have recently used alcohol, sedatives, tranquilizers, or other narcotic medications.

To make sure Fioricet is safe for you, tell your doctor if you have:

    • liver disease, cirrhosis, a history of alcoholism or drug addiction, or if you drink more than 3 alcoholic beverages per day;
    • kidney disease;
    • asthma, sleep apnea, or other breathing disorder;
    • stomach ulcer or bleeding;
    • a history of skin rash caused by any medication;
    • a history of mental illness or suicidal thoughts; or
    • if you use medicine to prevent blood clots.

It is not known whether Fioricet will harm an unborn baby. If you use butalbital while you are pregnant, your baby could become dependent on the drug.

This can cause life-threatening withdrawal symptoms in the baby after it is born. Babies born dependent on habit-forming medicine may need medical treatment for several weeks. Tell your doctor if you are pregnant or plan to become pregnant.
