Acetaminophen, caffeine, and dihydrocodeine (Oral route)
a-seet-a-MIN-oh-fen, KAF-een, dye-hye-droe-KOE-deen bye-TAR-trate
Acetaminophen/caffeine/dihydrocodeine bitartrate expose patients and other users to the risks of opioid addiction, abuse and misuse, which can lead to overdose and death; assess risk prior to prescribing, and monitor for development of these behaviors and conditions. Serious, life-threatening, or fatal respiratory depression may occur; monitor closely, especially upon initiation or following a dose increase. Accidental ingestion, especially by children, can result in a fatal overdose. Prolonged treatment during pregnancy can cause neonatal withdrawal syndrome, which may be life threatening. Respiratory depression and death have occurred in children who received codeine following tonsillectomy and/or adenoidectomy and had evidence of being ultra-rapid metabolizers of codeine due to CYP2D6 polymorphism. Acetaminophen has been associated with cases of acute liver failure, at times resulting in liver transplant and death. Most of the cases are associated with the use of acetaminophen at doses that exceed 4,000 milligrams per day, and often involve more than one acetaminophen-containing product. The effects of concomitant use or discontinuation of cytochrome P450 3A4 inducers, 3A4 inhibitors, or 2D6 inhibitors with codeine are complex and requires careful consideration. Concomitant use of may result in altered drug concentrations, potentially causing opioid toxicity, opioid withdrawal or reduced analgesic efficacy. Concomitant use of opioids with benzodiazepines or other central nervous system depressants, including alcohol, may result in profound sedation, respiratory depression, coma, and death. If concomitant use is necessary, minimize dose and duration, and monitor patients for signs and symptoms of respiratory depression and sedation .
Uses of This Medicine:
Acetaminophen, caffeine, and dihydrocodeine combination is used to relieve severe pain.
Acetaminophen is used to relieve pain and reduce fever in patients. It does not become habit-forming when taken for a long time. But acetaminophen may cause other unwanted effects when taken in large doses, including liver damage. Caffeine is a CNS stimulant that is used with pain relievers to increase their effect. It has also been used for migraine headaches. Dihydrocodeine belongs to the group of medicines called narcotic analgesics (pain medicines). It acts on the central nervous system (CNS) to relieve pain.
When dihydrocodeine is used for a long time or in large doses, it may become habit-forming, causing mental or physical dependence. However, people who have continuing pain should not let the fear of dependence keep them from using narcotics to relieve their pain. Mental dependence (addiction) is not likely to occur when narcotics are used for this purpose. Physical dependence may lead to withdrawal side effects if treatment is stopped suddenly. However, severe withdrawal side effects can usually be prevented by gradually reducing the dose over a period of time before treatment is stopped completely.
This medicine is available only with your doctor's prescription.
Before Using This Medicine:
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines.

Appropriate studies have not been performed on the relationship of age to the effects of Trezix™ in the pediatric population. Safety and efficacy have not been established.
Trezix™ should not be used to relieve pain after surgery removal of tonsils and/or adenoids in any children. Severe breathing problems and deaths have been reported in some children who received codeine after tonsil or adenoid surgery.
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of acetaminophen, caffeine, and dihydrocodeine combination in the elderly. However, elderly patients are more likely to have age-related lung, liver, kidney, or heart problems, which may require caution and an adjustment in the dose for patients receiving acetaminophen, caffeine, and dihydrocodeine combination in order to avoid potentially serious side effects.

Codeine is changed to morphine in the body. Some people change codeine to morphine more quickly than others. These individuals are called "ultra-rapid metabolizers of codeine". Contact your doctor immediately if you experience extreme sleepiness, confusion, or shallow breathing. These symptoms may indicate that you are an "ultra-rapid metabolizer of codeine". As a result, there is too much morphine in the body and more side effects of morphine than usual. Children may be especially sensitive to this effect.
