Fioricet with Codeine (Page 5 of 12)
5.13 Risks of Use in Patients with Increased Intracranial Pressure, Brain Tumors, Head Injury, or Impaired Consciousness
In patients who may be susceptible to the intracranial effects of CO2 retention (e.g., those with evidence of increased intracranial pressure or brain tumors), FIORICET with CODEINE may reduce respiratory drive, and the resultant CO2 retention can further increase intracranial pressure. Monitor such patients for signs of sedation and respiratory depression, particularly when initiating therapy with FIORICET with CODEINE.
Opioids may also obscure the clinical course in a patient with a head injury. Avoid the use of FIORICET with CODEINE in patients with impaired consciousness or coma.
5.14 Risks of Use in Patients with Gastrointestinal Conditions
FIORICET with CODEINE is contraindicated in patients with known or suspected gastrointestinal obstruction, including paralytic ileus.
The codeine in FIORICET with CODEINE may cause spasm of the sphincter of Oddi. Opioids may cause increases in serum amylase. Monitor patients with biliary tract disease, including acute pancreatitis for worsening symptoms.
5.15 Increased Risk of Seizures in Patients with Seizure Disorders
The codeine in FIORICET with CODEINE may increase the frequency of seizures in patients with seizure disorders and may increase the risk of seizures occurring in other clinical settings associated with seizures.
Monitor patients with a history of seizure disorders for worsened seizure control during FIORICET with CODEINE therapy.
Do not abruptly discontinue FIORICET with CODEINE in a patient physically dependent on opioids. Rapid tapering of FIORICET with CODEINE in a patient physically dependent on opioids may lead to a withdrawal syndrome and return of pain [see Dosage and Administration (2.4), Drug Abuse and Dependence (9.3)].
Additionally, avoid the use of mixed agonist/antagonist (e.g., pentazocine, nalbuphine, and butorphanol) or partial agonist (e.g., buprenorphine) analgesics in patients who are receiving a full opioid agonist analgesic, including FIORICET with CODEINE. In these patients, mixed agonist/antagonist and partial agonist analgesics may reduce the analgesic effect and/or precipitate withdrawal symptoms.
When discontinuing FIORICET with CODEINE, in a physically-dependent patient, gradually taper the dosage [see Dosage and Administration (2.4)]. Abrupt discontinuation of butalbital can cause seizures [see Drug Abuse and Dependence (9.3)].
5.17 Risks of Driving and Operating Machinery
FIORICET with CODEINE may impair the mental or physical abilities needed to perform potentially hazardous activities such as driving a car or operating machinery. Warn patients not to drive or operate dangerous machinery unless they are tolerant to the effects of FIORICET with CODEINE and know how they will react to the medication.
5.18 Serious Skin Reactions
Rarely, acetaminophen may cause serious skin reactions such as acute generalized exanthematous pustulosis (AGEP), Stevens-Johnson Syndrome (SJS), and toxic epidermal necrolysis (TEN), which can be fatal. Patients should be informed about the signs of serious skin reactions, and use of the drug should be discontinued at the first appearance of skin rash or any other sign of hypersensitivity.
There have been post-marketing reports of hypersensitivity and anaphylaxis associated with the use of acetaminophen. Clinical signs included swelling of the face, mouth, and throat, respiratory distress, urticaria, rash, pruritus, and vomiting. There were infrequent reports of life-threatening anaphylaxis requiring emergency medical attention. Instruct patients to discontinue FIORICET with CODEINE immediately and seek medical care if they experience these symptoms. Do not prescribe FIORICET with CODEINE for patients with acetaminophen allergy.
5.20 Drug/Laboratory Test Interactions
Codeine: Codeine may increase serum amylase levels.
Acetaminophen: Acetaminophen may produce false positive test results for urinary 5‑hydroxyindoleacetic acid.

The following adverse reactions associated with the use of butalbital, acetaminophen, caffeine, and codeine phosphate were identified in clinical studies or post-marketing reports. Because some of these reactions were reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
The most frequently reported adverse reactions were drowsiness, lightheadedness, dizziness, sedation, shortness of breath, nausea, vomiting, abdominal pain, and intoxicated feeling.
All adverse events tabulated below are classified as infrequent.
Central Nervous: headache, shaky feeling, tingling, agitation, fainting, fatigue, heavy eyelids, high energy, hot spells, numbness, sluggishness, seizure. Mental confusion, excitement or depression can also occur due to intolerance, particularly in elderly or debilitated patients, or due to overdosage of butalbital.
Autonomic Nervous: dry mouth, hyperhidrosis.
Gastrointestinal: difficulty swallowing, heartburn, flatulence, constipation.
Musculoskeletal: leg pain, muscle fatigue.
Miscellaneous: pruritus, fever, earache, nasal congestion, tinnitus, euphoria, allergic reactions.
The following adverse reactions have been voluntarily reported as temporally associated with Butalbital, Aspirin, Caffeine, and Codeine Phosphate Capsules, a related product containing aspirin, butalbital, caffeine, and codeine phosphate.
Central Nervous: abuse, addiction, anxiety, disorientation, hallucination, hyperactivity, insomnia, libido decrease, nervousness, neuropathy, psychosis, sexual activity increase, slurred speech, twitching, unconsciousness, vertigo.
Autonomic Nervous: epistaxis, flushing, miosis, salivation.
