Nausea, vomiting, abdominal pain, shaking (tremor), shortness of breath, increased urination, lightheadedness, dizziness, drowsiness, or trouble sleeping may occur.
If any of these effects persist or worsen, tell your doctor or pharmacist promptly.
To reduce your risk of dizziness and lightheadedness, get up slowly when rising from a sitting or lying position.
Stop using Fioricet and call your doctor at once if you have:
- confusion, seizure (convulsions);
- shortness of breath;
- a light-headed feeling, like you might pass out; or
- nausea, upper stomach pain, itching, loss of appetite, dark urine, clay-colored stools, jaundice (yellowing of the skin or eyes).
What Are the Possible Side-Effects of Fioricet?
Like any medication, Fioricet can cause side-effects. People who misuse Fioricet or use it compulsively are at greater risk for experiencing the worst side-effects of the medication.
The possible side-effects of Fioricet are:
-
-
- Anxiety
- Dizziness
- Drowsiness
- Feelings of being intoxicated
- Lightheartedness
- Nausea and vomiting
- Shaking and tremors
- Shortness of breath

What are the Symptoms of a Fioricet Overdose?
While butalbital is the addictive ingredient in Fioricet, acetaminophen is the ingredient which is liable to cause an overdose. Unfortunately, people who misuse Fioricet as a recreational drug or as a way to suppress withdrawal are most likely to suffer an overdose.
When a person overdoses on Fioricet, the acetaminophen will damage their liver. In severe cases, an overdose can even provoke fatal liver failure. For this reason, it is dangerous to take Fioricet together with another medication which contains acetaminophen because it increases the risk of overdose and death. Furthermore, drinking alcohol while taking Fioricet may also inflict liver damage.
A Fioricet overdose is a medical emergency, so it’s important to know the symptoms. An overdose on Fioricet and all other forms of liver failure cause jaundice, the yellowing of the skin and eyes. Other symptoms of an overdose include:
-
- Confusion
- Convulsions and seizures
- Fainting
- Irregular heartbeat
- Lack of appetite
- Nausea and vomiting
- Restlessness
- Stomach pain
- Sweating
- Tremors
