Generic Name: aspirin/butalbital/caffeine (AS-pir-in/byoo-TAL-bi-tal/kaf-EEN)
Brand Name: Examples include Farbital and Fiorinal
Children and teenagers should not use aspirin, aspirin-containing, or aspiring-related medicines for flu symptoms or chickenpox without first consulting a doctor. A rare but serious illness known as Reye syndrome may occur.
Farbital is used for:
Treating tension headaches. It may also be used for other conditions as determined by your doctor.
How these medicines work is not completely understood. Aspirin reduces pain and inflammation. Caffeine may work by constricting blood vessels that may cause headaches. Butalbital has a depressant effect that reduces anxiety and causes relaxation.
Do NOT use Farbital if:
- you are allergic to nonsteroidal anti-inflammatory drugs (NSAIDs) (eg, ibuprofen) or any ingredient in Farbital
- you have Von Willebrand disease, porphyria, or bleeding or blood clotting problems
- you are taking sodium oxybate (GHB), heparin, probenecid, or sulfinpyrazone
- your child has the flu, chickenpox, or joint problems
Contact your doctor or health care provider right away if any of these apply to you.

This may not be a complete list of all interactions that may occur. Ask your health care provider if Farbital may interact with other medicines that you take. Check with your health care provider before you start, stop, or change the dose of any medicine.
How to use Farbital:
Use Farbital as directed by your doctor. Check the label on the medicine for exact dosing instructions.
- Take Farbital by mouth with or without food. If stomach upset occurs, take with food to reduce stomach irritation. Taking it with food may not decrease the risk of stomach or bowel problems (such as bleeding or ulcers) that may occur while taking Farbital. Talk with your doctor or pharmacist if you experience persistent stomach upset.
- Do not take Farbital if it has a strong vinegar-like smell, or if any vinegar smell remains after leaving the bottle open for 10 minutes.
- If you miss a dose of Farbital and you are taking it regularly, take it as soon as possible. If several hours have passed or if it is almost time for your next dose, do not double the dose to catch up, unless advised to do so by your doctor. Do not take 2 doses at once.
Ask your health care provider any questions you may have about how to use Farbital.
Important safety information:
- Farbital may cause drowsiness or dizziness. These effects may be worse if you take it with alcohol or certain medicines. Use Farbital with caution. Do not drive or perform other possibly unsafe tasks until you know how you react to it.
- Do not drink alcohol or use medicines that may cause drowsiness (eg, sleep aids, muscle relaxers) while you are using Farbital; it may add to their effects. Ask your pharmacist if you have questions about which medicines may cause drowsiness.
- Serious stomach ulcers or bleeding can occur with the use of Farbital. Taking it in high doses or for a long time, smoking, or drinking alcohol increases the risk of these side effects. Taking Farbital with food will NOT reduce the risk of these effects. Contact your doctor or emergency room at once if you develop severe stomach or back pain; black, tarry stools; vomit that looks like blood or coffee grounds; or unusual weight gain or swelling.
- Tell your doctor or dentist that you take Farbital before you receive any medical or dental care, emergency care, or surgery.
- Farbital has aspirin in it. Before you start any new medicine, check the label to see if it has aspirin in it too. If it does or if you are not sure, check with your doctor or pharmacist.
- Do NOT take more than the recommended dose or use for longer than prescribed without checking with your doctor. Taking more than the recommended dose or taking Farbital for longer than prescribed may be habit-forming.
- Aspirin has been linked to a serious illness called Reye syndrome. Do not give Farbital to a child or teenager who has the flu, chickenpox, or a viral infection. Contact your doctor with any questions or concerns.
- Hormonal birth control (eg, birth control pills) may not work as well while you are using Farbital. To prevent pregnancy, use an extra form of birth control (eg, condoms).
- Use Farbital with caution in the ELDERLY; they may be more sensitive to its effects.
- Farbital should not be used in CHILDREN younger than 12 years old; safety and effectiveness in these children have not been confirmed.
- PREGNANCY and BREAST-FEEDING: If you become pregnant, contact your doctor. You will need to discuss the benefits and risks of using Farbital while you are pregnant. Farbital is not recommended during the last 3 months (third trimester) of pregnancy because it may cause harm to the fetus. Farbital is found in breast milk. If you are or will be breast-feeding while you use Farbital, check with your doctor. Discuss any possible risks to your baby.
When used for long periods of time or at high doses, Farbital may not work as well and may require higher doses to obtain the same effect as when originally taken. This is known as TOLERANCE. Talk with your doctor if Farbital stops working well. Do not take more than prescribed.
Some people who use Farbital for a long time may develop a need to continue taking it. People who take high doses are also at risk. This is known as DEPENDENCE or addiction. If you suddenly stop taking Farbital, you may experience WITHDRAWAL symptoms, including anxiety, muscle twitching, trembling hands and fingers, weakness, dizziness, hallucinations, nausea, vomiting, sleeplessness, lightheadedness, or seizures.
