What should I avoid while taking Fioricet?
Fioricet 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.
Avoid taking Fioricet with medications that affect your concentration, such as other narcotic pain relievers, general anesthetics, sleeping pills, anti-allergy medications, sedative-hypnotics, and tranquilizers (such as chlordiazepoxide). These may cause further drowsiness.
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 Fioricet, avoid taking diet pills, caffeine pills, or other stimulants (such as ADHD medications) without your doctor’s advice.
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.
