Butalbital is a barbiturate sedative sold only in combinations, such as Fioricet (with acetaminophen and caffeine) and Fiorinal (with aspirin and caffeine), for tension headaches. Fiorinal is Schedule III; most acetaminophen versions are exempt from federal scheduling. Frequent use causes rebound headaches and dependence, and stopping suddenly can cause seizures.

Fioricet uses: what butalbital is prescribed for

Butalbital combinations relieve tension-type headache. Butalbital relaxes muscles and causes sedation; the other ingredients relieve pain.[1]

The American Headache Society advises against butalbital for migraine and limits its use because of rebound headaches, dependence, and withdrawal risks. Most countries do not sell it.[1]

Fioricet dosage: how butalbital is usually prescribed

The figures below come from the FDA-approved label and describe how prescribers typically use butalbital. They are not personal dosing advice. A prescriber sets the dose for each person and adjusts it over time.[1]

ProductTypical adult doseNotes from the label
Fioricet (50 mg butalbital, 300 to 325 mg acetaminophen, 40 mg caffeine)1 or 2 capsules every 4 hoursMaximum 6 capsules a day
Fiorinal (with 325 mg aspirin)1 or 2 capsules every 4 hoursMaximum 6 a day
FrequencyNo more than a few days a monthMore frequent use causes medication overuse headache

Fioricet (butalbital) side effects and risks

FDA boxed warnings

  • Acetaminophen-containing products: liver failure, sometimes requiring transplant or causing death, from doses above 4,000 mg of acetaminophen a day.
  • Codeine-containing products carry the opioid boxed warnings, including addiction, slowed breathing, and danger with benzodiazepines.

Common side effects include drowsiness, dizziness, lightheadedness, and nausea.[1]

Medication overuse headache: taking butalbital on more than a few days a month makes headaches more frequent.

Dependence: regular use leads to barbiturate dependence; daily high doses can cause life-threatening withdrawal.

Fioricet overdose: signs of butalbital overdose and what to do

Overdose causes drowsiness, confusion, slowed breathing, low blood pressure, and coma. Acetaminophen overdose may cause no early symptoms but can destroy the liver over 1 to 3 days, so seek care immediately.[1]

If someone may have overdosed

  • Call 911 if the person is unresponsive, hard to wake, or breathing slowly.
  • For advice when the person is awake and stable, call Poison Help at 1-800-222-1222 (US, free, 24 hours).
  • If opioids could be involved, including pills not from a pharmacy, give naloxone if you have it. Naloxone does not reverse butalbital, but it will not harm the person.
  • Stay with the person and place them on their side if they are drowsy or vomiting.

Fioricet withdrawal timeline: how long butalbital withdrawal lasts

People who take butalbital daily, especially at high doses, can become physically dependent. Barbiturate withdrawal can be dangerous.[1]

  1. Day 1 to 2Symptoms beginAnxiety, rebound headache, tremor, weakness, nausea, and insomnia.
  2. Days 2 to 5Peak riskSeizures and delirium can occur after heavy use.
  3. 1 to 2 weeksResolvesSymptoms ease with a supervised taper.

Warning: Stopping high-dose daily butalbital suddenly can cause seizures. Withdrawal should be managed by a clinician, often with phenobarbital.

Can you order Fioricet (butalbital) online legally?

Yes, but only with a valid prescription and only from a pharmacy licensed in your state. Many licensed pharmacies, including mail-order pharmacies run by insurers, fill butalbital prescriptions online and ship them. Buying butalbital from a website that does not require a prescription is illegal, and the product is often fake.[5][7]

  1. See a licensed clinicianA clinician evaluates you in person or by telemedicine and decides whether butalbital is appropriate.
  2. The prescription goes to a pharmacyPrescriptions are usually sent electronically, straight from the prescriber to the pharmacy you choose.
  3. The pharmacy checks and fills itA pharmacist verifies the prescription and your identity, then dispenses the medicine in person or by mail.

Signs that an online seller is illegal:

  • It sells butalbital with no prescription, or after only a short online questionnaire.
  • It takes orders through social media, messaging apps, or email.
  • It asks for payment in cryptocurrency, gift cards, or money transfers.
  • It has no US street address, no state pharmacy license, and no pharmacist to speak to.
  • Its prices are far below those of ordinary pharmacies, or it ships from another country.

The FDA's BeSafeRx tool links to each state's license lookup, and the National Association of Boards of Pharmacy lists verified online pharmacies.[5][6]

Fioricet price: how much does Fioricet (butalbital) cost without insurance?

Generic butalbital combinations are inexpensive.

What you pay depends on the strength, the number of doses, your insurance plan, and the pharmacy. Cash prices for the same prescription can differ several times over between pharmacies in the same town, so check current prices before you fill it.

Ways to pay less, legally:

  • Ask the prescriber whether a generic butalbital is available. FDA-approved generics work the same way as the brand and usually cost much less.
  • Compare cash prices between pharmacies before you fill the prescription.
  • Use a free prescription discount card, such as GoodRx or SingleCare, when you pay cash. These cards cannot be combined with insurance on the same fill.
  • For brand-name medicines, check the manufacturer's savings program or patient assistance program.
  • Ask about a 90-day supply or your insurer's mail-order pharmacy, which often lowers the cost per dose when your prescriber agrees it is appropriate.

Warning: A price far below what licensed pharmacies charge, especially with no prescription required, is a strong sign of an illegal seller and counterfeit medicine.[5]

Common questions about Fioricet (butalbital)

Is Fioricet a controlled substance?

Most Fioricet products are exempt from federal scheduling, but Fiorinal and codeine versions are Schedule III, and some states control all of them.

Is Fioricet (butalbital) good for migraine?

No. Headache specialists advise against it for migraine; triptans and other treatments work better.

Can Fioricet (butalbital) cause rebound headaches?

Yes. Frequent use is a common cause of medication overuse headache.

Is Fioricet (butalbital) a barbiturate?

Yes. It is a short-to-intermediate acting barbiturate.

Can you stop Fioricet (butalbital) suddenly?

Occasional users can, but people taking it daily should taper with a clinician because of seizure risk.

Can you buy Fioricet (butalbital) without a prescription?

No. Fioricet (butalbital) is a Schedule III controlled substance in the US, so it is illegal to buy or possess it without a valid prescription. Websites and social media sellers that offer it without one are not legal pharmacies, and the DEA warns that pills sold this way are often counterfeit and can contain fentanyl. The legal route is a visit with a licensed clinician, in person or by telehealth, and a prescription filled at a state-licensed pharmacy. The FDA's BeSafeRx tool and the NABP's safe pharmacy list help confirm an online pharmacy is real.
