Things to note about Fioricet
Fioricet can be habit-forming, so you should use extreme caution if you decide to take it. Additionally, some people who take barbituates or opioids for extended periods can experience rebound headaches, which can increase in severity. These are also known as MOH, or medication overuse headaches.1
Barbituates can cause drowsiness, and their effect can be increased by alcohol use. It is important not to drive or use heavy machinery until you know how this drug affects you.2
Before taking Fioricet, tell your doctor if you:
- Are allergic to any ingredients in the medication
- Are taking blood thinners, antidepressants, antihistamines, or other sedatives like sleeping pills or tranquilizers.
- Are taking pain medications. Many over-the-counter pain relievers contain acetaminophen, and too much of this drug can be harmful.
- Have ever had liver disease, porphyria, or depression
- Are pregnant, plan to become pregnant, or are breastfeeding2
You should begin no medication or supplement without first checking with your health care provider and should let them know of any other prescriptions, OTCs, and herbals you are taking to ensure there are no interactions.
Fioricet is available in tablet form. Total dosage should not exceed 6 tablets. Butalbital is habit-forming. Consequently, the extended use of this product is not recommended. The CNS effects of butalbital may be enhanced by monoamine oxidase (MAO) inhibitors. Fioricet may enhance the effects of other narcotic analgesics, alcohol, general anesthetics, and tranquilizers such as chlordiazepoxide, sedative-hypnotics, or other CNS depressants. This product should be given to pregnant women only when clearly needed. Because of the potential for serious adverse reactions in nursing infants, a decision should be made whether to discontinue nursing or to discontinue the drug.
