Fioricet Dosing

Fioricet Dosing an introduction

How to Take Fioricet

Doses of Fioricet work differently in different people. The dose should therefore be made on an individual basis, weighing the possible benefit of a higher dose with possible side effect risks including drug dependence.

It may be helpful to keep track of your tension or migraine headaches using a migraine journal each day when you first begin taking Fioricet. Record your headache pain symptoms as they occur. This will help you know if the medicine is working for you at the dose you are taking.

Recommended Fioricet Dosage

Take 1 or 2 tablets every 4 hours as needed for pain. Total daily dosage should not exceed 6 tablets.

Long-term and repeated use of Fioricet is not recommended because it can lead to drug dependence.

Caution when using Acetaminophen

The maximum daily dose of acetaminophen (an ingredient in Fioricet) if you do not have liver problems is 4000 mg (4 g) per day for adults.

Many over the counter and prescription drug products contain acetaminophen. Always be aware of the components of any drug you are taking and check with your doctor of pharmacist if you are unsure about acetaminophen total daily dose. Taking more than the maximum daily dose of acetaminophen may cause serious liver damage that could lead to death. If you have any of the following symptoms of liver damage, call your doctor immediately:

  • Persistent nausea or vomiting
  • Yellowing of your eyes or skin
  • Dark-colored urine
  • Severe abdominal pain or stomach pain
  • Extreme fatigue


Work with your doctor to determine the best dose of Fioricet to start at for your individual needs and be sure to tell your doctor about all the drugs you are taking.

Fioricet is Not Recommended for Children

The safety and effectiveness of Fioricet in children under the age of 12 has not been proven.


Fioricet Use in Older Adults

Studies of Fioricet did not include enough people age 65 and older to determine if they respond differently to the medicine than younger people. If you are an older adult using Fioricet, you should usually start at the lowest possible dose recommended by your doctor. Older adults are at increased risk of liver, kidney and heart conditions and often have other health conditions and are taking other medications.

Butalbital (an ingredient in Fioricet) is heavily removed from the body by the kidney, and the risk of toxic reactions to Fioricet may be greater in people who have kidney damage. Because older adults are more likely to have kidney damage, they should usually start with the lowest possible dose recommended by their doctor. Older adults may also want to have their kidney function monitored while they are taking Fioricet.
