butalbital / acetaminophen / caffeine
Fioricet is a combination medication containing butalbital, acetaminophen, and caffeine. It's taken by mouth as needed, typically every 4 hours, to treat tension headaches. But it's not a first-choice option because it can become habit-forming and can worsen headaches if taken too frequently. In addition, Fioricet can cause side effects, such as sleepiness and dizziness. It's available as pills and an oral syrup.
What is Fioricet?
What is Fioricet used for?
- Tension headaches
How Fioricet works
Fioricet is a combination of three medications that work together to help relieve headache pain.
- Butalbital is a barbiturate that works by raising the levels of chemicals that cause your brain to relax.
- Acetaminophen is an analgesic. It stops the production of certain chemicals in your brain, which can help relieve pain.
- Caffeine is an adenosine antagonist. It blocks a natural chemical in your body called adenosine. It's unclear exactly how caffeine works to treat headaches, but it's thought to boost the pain-relieving activity of acetaminophen.

Pharmacist tips for Fioricet
- Fioricet can make you sleepy, dizzy, and lightheaded. Don't drive or use any heavy machinery until you know how the medication affects you.
- Avoid alcohol while taking Fioricet because it can make you more drowsy and dizzy, raise your risk of accidental injuries and liver damage, and worsen headaches
- Take Fioricet exactly as your provider instructed you to. Don't change your dose or stop taking Fioricet without talking to your provider first. To stop the medication, they might need to lower your dose slowly before stopping it completely. This lowers your risk of getting withdrawal symptoms, such as seizures, hallucinations, and worsening of headaches.
- Make sure to tell your provider about all of the medications you're taking before starting Fioricet. Don't start any new medications while taking Fioricet without talking to your provider first to make sure the combination is safe to take.
- Many over-the-counter and prescription medications contain acetaminophen. Don't use other medications containing acetaminophen unless your provider specifically said it was okay for you to do so. Ask your provider or pharmacist if you aren't sure if a certain medication contains acetaminophen.
- Store Fioricet at room temperature in a place out of reach from children due to the life-threatening risk of accidental overdose and misuse. If you don't need to take Fioricet anymore, choose a medication take-back option to get rid of it safely.
- 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.
- For the liquid form: Make sure to only use a medication dose cup or oral syringe from the pharmacy to measure out your dose. Don't use household spoons because they aren't accurate and might cause you to take the wrong dose.
Risks and warnings for Fioricet
Fioricet can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Liver damage
- Risk factors: Drinking alcohol | Taking other medications containing acetaminophen | Taking too much Fioricet | History of liver problems
Taking too much acetaminophen can cause liver damage that can be permanent and life-threatening. For adults, the maximum amount of acetaminophen is 3 or 4 grams in a 24-hour period, depending on your provider's instructions.
Speak to your provider before using Fioricet if you have liver problems since it can cause further damage to your liver. Also, avoid drinking alcohol while taking Fioricet because this combination can harm your liver too.
Signs of liver problems include dark urine, feeling tired, upset stomach or stomach pain, or yellowing of the skin or whites of the eyes. If you notice any of these symptoms, call your provider right away.
Difficulty concentrating and extreme sleepiness
- Risk factors: Taking high doses of Fioricet | Age 65 years or older | Drinking alcohol | Taking other medications that can cause sleepiness
Fioricet can cause extreme sleepiness and lower your ability to think, react, and focus. Don't drink alcohol or take other medications that can cause sleepiness or "brain fog", such as pain medications or antidepressants, with Fioricet. Doing so can worsen these side effects. Make sure you know how this medication affects you before driving a car or doing activities that require your concentration. Talk to your healthcare provider right away if you feel too sleepy from taking Fioricet.
Serious skin or allergic reactions
- Risk factors: History of serious skin reactions | Allergy to acetaminophen (Tylenol)
Fioricet contains acetaminophen (Tylenol), which can rarely cause life-threatening skin reactions and allergic reactions. If you're allergic to acetaminophen, don't take Fioricet. If you develop symptoms of an allergic reaction, such as swelling of the face, mouth, or throat, trouble breathing, itchy red rash (hives), or vomiting, stop taking Fioricet and call for emergency medical help right away. If you develop symptoms of a skin reaction, such as a reddening or peeling of the skin, painful rash, or fluid-filled blisters, stop taking Fioricet and go to the emergency room right away.
Misuse, dependence, and withdrawal
- Risk factors: Taking Fioricet longer than prescribed | Taking higher doses of Fioricet than prescribed | Taking Fioricet more often than prescribed
Fioricet contains butalbital, which can be habit-forming. Misuse of Fioricet can lead to dependence, accidental overdose, and even death. Doing so can also cause withdrawal symptoms, like seizures, restlessness, trouble sleeping, and shakiness, if you lower your dose or stop taking the medication suddenly. To lower the risk of physical dependence, don't take Fioricet longer than prescribed, at higher doses than prescribed, or more often than prescribed.
Call for emergency medical help if you have any symptoms of taking too much butalbital, including sleepiness, trouble breathing, dizziness, confusion, or loss of consciousness. If you no longer want to take Fioricet, talk to your healthcare provider so they can instruct you on how to stop taking the medication safely. Speak to your healthcare provider about alternative treatments if you have concerns about taking Fioricet.
