butalbital / acetaminophen / caffeine
Fioricet is a headache medication that contains butalbital (a barbiturate), acetaminophen (a pain reliever), and caffeine (a stimulant). It's used to treat tension headaches in adults and children ages 12 and older. Fioricet comes as brand-name capsules as well as generic tablets, capsules, and oral solution. It's usually taken by mouth every 4 hours as needed. Common side effects include sleepiness and dizziness. Fioricet isn't a first-choice treatment because it can be habit-forming and cause "rebound headaches" if used too often.

How Fioricet works
Fioricet contains three medications that work together to help relieve headache pain.
-
Butalbital is a barbiturate. It works by helping to calm activity in your brain.
-
Acetaminophen is an analgesic. It blocks certain chemicals in your brain to help ease pain.
-
Caffeine is a type of stimulant called an adenosine antagonist. It blocks a natural chemical in your body called adenosine, which might play a role in headache pain. While it's not clear exactly how caffeine helps with headaches, it might also help acetaminophen work better to relieve pain.

Pharmacist tips for Fioricet
- Take Fioricet exactly as your prescriber tells you to. Don't take more than prescribed or take it more often than directed. Taking too much can cause serious side effects, including overdose.
- Avoid taking Fioricet too often. Taking it for 10 days or more per month can raise your risk of rebound headaches. This means your headaches can happen more often or get worse. Tell your prescriber if you need Fioricet more often than usual. They can help you find better options for headache relief.
- For Fioricet and generic pills: Take Fioricet capsules and tablets as directed. Swallow capsules whole; don't open or crush them. Ask your prescriber or pharmacist before cutting or crushing tablets.
- For the generic liquid form: Measure each dose with a medication cup or oral syringe from your pharmacy. Don't use kitchen spoons because you might take the wrong dose.
- Fioricet can make you feel sleepy, dizzy, or lightheaded. Don't drive or use any heavy machines until you know how the medication affects you.
- Avoid alcohol while taking Fioricet. Alcohol can make you more sleepy or dizzy. This can raise your risk of accidents, overdose, and liver damage.
- It's a good idea to limit other sources of caffeine while taking Fioricet. Each capsule or tablet contains 40 mg of caffeine. The liquid contains 40 mg of caffeine per 15 mL. Too much caffeine can cause a fast heartbeat, shaking, or trouble sleeping. Keep track of how much caffeine you get from things like coffee, tea, and energy drinks.
- Tell your prescriber and pharmacist about all the medications you take and plan to take. Taking Fioricet with medications like opioids or sleep medications can cause severe sleepiness or slow breathing. Antidepressants called monoamine oxidase inhibitors (MAOIs) can also raise your risk of side effects. Check with your care team before starting any new medications.
- Check medication labels before taking other pain, headache, or cold medications with Fioricet. Many of these products contain acetaminophen, which is also in Fioricet. Look for “acetaminophen” or “APAP” on the label. Taking more than one product with acetaminophen can raise your risk of liver damage. Ask your prescriber or pharmacist before taking these products together.
- Don't stop taking Fioricet suddenly if you've been using it regularly. Talk to your prescriber first. Stopping too quickly can cause withdrawal symptoms, like restlessness or even seizures. Your prescriber can help you stop taking Fioricet safely.
- Store Fioricet in a safe place at room temperature, away from children. Accidental use can cause a life-threatening overdose. If you don't need to take Fioricet anymore, use a medication take-back program to get rid of it safely.
- Get emergency medical help if someone takes too much Fioricet. You can also call Poison Control at 1-800-222-1222 for help. Don't wait for symptoms to appear.
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 with acetaminophen | Taking more than one medication containing acetaminophen | Taking too much Fioricet | Liver problems
Fioricet contains acetaminophen (Tylenol). Taking too much acetaminophen can cause serious and sometimes life-threatening liver damage. For healthy adults, the maximum amount of acetaminophen is usually 4,000 mg in 24 hours. But some people might meed a lower limit, such as 2,000 mg, depending on their risk of liver damage.
Check with your prescriber or pharmacist before taking other medications that contain acetaminophen. Look for "acetaminophen" or "APAP" on medication labels. Taking more than one product with acetaminophen can make it easier to take too much. Avoid alcohol while taking Fioricet because it can raise your risk of liver damage. Tell your prescriber if you have liver problems before taking Fioricet.
Get medical help right away if you take too much acetaminophen, even if you feel fine. Also get medical help right away if you notice signs of liver problems. These can include dark urine, severe tiredness, nausea, stomach pain, or yellow skin or eyes.
Extreme sleepiness and trouble concentrating
- Risk factors: Age 65 years or older | Drinking alcohol | Taking high doses of Fioricet | Taking other medications that can cause sleepiness or slow your body down
Fioricet can make you feel very sleepy. It can also make it harder to think, react quickly, and focus. Medications that make you sleepy, like sedatives and muscle relaxants, can make the effects worse. Alcohol can also make these side effects stronger.
Don't drive or do anything that requires you to be alert until you know how Fioricet affects you. Avoid drinking alcohol or taking other medications that can cause "brain fog" unless your prescriber says it's safe. Tell your care team right away if you feel very sleepy while taking Fioricet.
Serious allergic reactions or skin reactions
- Risk factors: Allergy to acetaminophen (Tylenol) | Allergy to butalbital | Allergy to caffeine
Fioricet contains acetaminophen (Tylenol). This ingredient can cause serious allergic reactions. Don't take Fioricet if you're allergic to acetaminophen or any of Fioricet's other ingredients.
Get emergency help right away if you have signs of a severe allergic reaction called anaphylaxis. Signs include swelling of your face, lips, or tongue, trouble breathing, tightness in your throat, or hives.
Acetaminophen can also cause rare but serious skin reactions. Stop taking Fioricet and get medical help right away if you notice a painful rash, red skin, blisters, or peeling skin.
Risk of 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. Taking Fioricet for a long time, especially at high doses, can lead to physical dependence. This means your body gets used to the medication and needs it to feel normal.
Over time, you might also build tolerance to Fioricet. This means you might need higher doses to get the same effect. This raises your risk of taking too much Fioricet. It can raise your risk of overdose and death. Get emergency medical help if you have signs of an overdose, such as extreme sleepiness, confusion, or trouble breathing. To lower these risks, don't take Fioricet more often, at higher doses, or for longer than prescribed.
If you suddenly stop taking Fioricet after taking it for a long time, you might have withdrawal symptoms. These include restlessness, trouble sleeping, shaking, or seizures. Talk to your prescriber first before stopping Fioricet. They can help you stop the medication safely.
