Fioricet can cause excessive sleepiness, dizziness, and lightheadedness. Don’t drive or use any heavy machinery until you know how the medication affects you.
Since Fioricet contains some caffeine, be sure to limit how much caffeine you use per day. Too much caffeine can lead to nervousness, shakiness, restlessness, trouble sleeping, and a fast heart rate.
Avoid drinking alcohol while taking Fioricet, since it can cause you to be more drowsy and less alert, and raise your risk of accidental injuries and liver damage.
Many over-the-counter and prescription medications contain acetaminophen. Don’t take more than 3 to 4 grams of acetaminophen per day to avoid liver damage. Ask your provider what your maximum daily amount of acetaminophen is, since this depends on your provider’s instructions.
Use caution if you currently take medications called monoamine oxidase inhibitors (MAOIs), such as phenelzine (Nardil), tranylcypromine (Parnate), or selegiline (Eldepryl). Taking a MAOI with Fioricet can lead to sleepiness, dizziness, and slowed breathing.
If you’re using the oral syrup form of Fioricet, use the dosing cup or syringe provided by your pharmacist to measure out your dose. Don’t use kitchen spoons or cups since they might not give you the most accurate dose.
Store Fioricet at room temperature in a place out of reach from children due to the life-threatening risk of accidental overdose, misuse, and abuse. If you or someone you know accidentally overdoses on Fioricet, get emergency medical help or call your local poison control center at 1-800-222-1222 right away.
