Indications and Usage for Acetaminophen Caffeine Dihydrocodeine
Acetaminophen, caffeine, and dihydrocodeine bitartrate tablets are indicated for the relief of moderate to moderately severe pain.
Selection of patients for treatment with Acetaminophen, Caffeine and Dihydrocodeine Bitartrate Tablets should be governed by the same principles that apply to the use of similar opioid/non-opioid fixed combination analgesics. As with any such opioid analgesic, the dosing regimen should be adjusted for each patient [see Dosage and Administration]. This combination product should be used with caution in elderly or debilitated patients or those with any of the following conditions: acute alcoholism; adrenocortical insufficiency (e.g., Addison's disease); asthma; central nervous system depression or coma; chronic obstructive pulmonary disease; decreased respiratory reserve (including emphysema, severe obesity, cor pulmonale, or kyphoscoliosis); delirium tremens; head injury; hypotension; increased intracranial pressure; myxedema or hypothyroidism; prostatic hypertrophy or urethral stricture; and toxic psychosis. The benefits and risks of using opioids in patients taking monoamine oxidase inhibitors and in those with a history of drug abuse should be carefully considered. The administration of an analgesic containing an opioid may obscure the diagnosis or clinical course in patients with acute abdominal conditions. This combination product may aggravate convulsions in patients with convulsive disorders and, like all opioids, may induce or aggravate seizures in some clinical settings.
Acetaminophen is relatively non-toxic at therapeutic doses, but should be used with caution in patients with severe renal or hepatic disease. Care should be observed when using large doses of acetaminophen in malnourished patients or those with a history of chronic alcohol abuse because they may be more susceptible to hepatic damage similar to that observed with toxic overdosage. Caffeine in high doses may produce central nervous system and cardiovascular stimulation and gastrointestinal irritation.
Dihydrocodeine with Other Central Nervous System Depressants:
Patients receiving other opioid analgesics, sedatives or hypnotics, muscle relaxants, general anesthetics, centrally acting anti-emetics, phenothiazines or other tranquilizers, or alcohol concomitantly with this combination product may exhibit additive depressant effects on the central nervous system. When such combined therapy is contemplated, the dose of one or both agents should be reduced.
Dihydrocodeine with Monoamine Oxidase Inhibitors:
Dihydrocodeine, like all opioid analgesics, interacts with monoamine oxidase inhibitors causing central nervous system excitation and hypertension.
Dihydrocodeine with Mixed Agonist/Antagonist Opioid Analgesics:
Agonist/antagonist analgesics (i.e., pentazocine, nalbuphine, butorphanol and buprenorphine) may reduce the analgesic effect of this combination product.
Acetaminophen Drug Interactions:
Chronic and excessive consumption of alcohol may increase the hepatotoxic risk of acetaminophen. The potential for hepatotoxicity with acetaminophen also may be increased in patients receiving anticonvulsants that induce hepatic microsomal enzymes (including phenytoin, barbiturates, and carbamazepine) or isoniazide. Chronic ingestion of large doses of acetaminophen may slightly potentiate the effects of warfarin and indandione- derivative anticoagulants. Severe hypothermia is possible in patients receiving acetaminophen concomitantly with phenothiazines.
Caffeine Drug Interactions:
Caffeine may enhance the cardiac inotropic effects of beta-adrenergic stimulating agents. Co-administration of caffeine and disulfiram may lead to a substantial decrease in caffeine clearance. Caffeine may increase the metabolism of other drugs such as phenobarbital and aspirin. Caffeine accumulation may occur when products or foods containing caffeine are consumed concomitantly with quinolones such as ciprofloxacin.
Information for Patients/Caregivers:
Patients receiving acetaminophen, caffeine and dihydrocodeine bitartrate tablets should be given the following information:
- Patients should be advised that acetaminophen, caffeine and dihydrocodeine bitartrate tablets may impair the mental or physical abilities required for the performance of potentially hazardous tasks such as driving a car or operating machinery.
- Patients should be advised to report adverse experiences occurring during therapy.
- Patients should be advised not to adjust the dose of acetaminophen, caffeine and dihydrocodeine bitartrate tablets without consulting the prescribing professional.
- Patients should not combine acetaminophen, caffeine and dihydrocodeine bitartrate tablets with alcohol or other central nervous system depressants (sleep aids, tranquilizers) except by the orders of the prescribing physician, because additive effects may occur.
- Women of childbearing potential who become, or are planning to become, pregnant should be advised to consult their physician regarding the effects of analgesics and other drug use during pregnancy on themselves and their unborn child.
- Patients should be advised that acetaminophen, caffeine, and dihydrocodeine bitartrate tablets are a potential drug of abuse. They should protect it from theft, and it should never be given to anyone other than the individual for whom it was prescribed.
- Do not take acetaminophen, caffeine, and dihydrocodeine bitartrate tablets if you are allergic to any of its ingredients.
- If you develop signs of allergy such as rash or difficulty breathing stop taking acetaminophen, caffeine, and dihydrocodeine bitartrate tablets and contact your healthcare provider immediately.
- Do not take more than 4,000 milligrams of acetaminophen per day. Call your doctor if you took more than the recommended dose.
Advise patients that some people have a genetic variation that results in dihydrocodeine changing into dihydromorphine more rapidly and completely than other people. Most people are unaware of whether they are an ultra-rapid dihydrocodeine metabolizer or not. These higher-than-normal levels of dihydromorphine in the blood may lead to life-threatening or fatal respiratory depression or signs of overdose such as extreme sleepiness, confusion, or shallow breathing. Children with this genetic variation who were prescribed codeine after tonsillectomy and/or adenoidectomy for obstructive sleep apnea may be at greatest risk based on reports of several deaths in this population due to respiratory depression. Dihydrocodeine-containing products are contraindicated in all children who undergo tonsillectomy and/or adenoidectomy. Advise caregivers of children receiving dihydrocodeine-containing products for other reasons to monitor for signs of respiratory depression.
Advise patients that nursing mothers taking dihydrocodeine can also have higher dihydromorphine levels in their breast milk if they are ultra-rapid metabolizers. These higher levels of dihydromorphine in breast milk may lead to life-threatening or fatal side effects in nursing babies. Advise nursing mothers to watch for signs of dihydromorphine toxicity in their infants including increased sleepiness (more than usual), difficulty breastfeeding, breathing difficulties, or limpness. Instruct nursing mothers to talk to the baby’s doctor immediately if they notice these signs and, if they cannot reach the doctor right away, to take the baby to an emergency room or call 911 (or local emergency services).
Teratogenic Effects – Pregnancy Category C. Animal reproduction studies have not been conducted with acetaminophen, caffeine and dihydrocodeine bitartrate tablets. It is also not known whether this combination product can cause fetal harm when administered to pregnant women or can affect reproduction capacity in males and females. This combination product should be given to pregnant women only if clearly needed, especially during the first trimester.
Labor and Delivery:
Acetaminophen, caffeine and dihydrocodeine bitartrate tablets are not recommended for use by women during and immediately before labor and delivery because oral opioids may cause respiratory depression in the newborn.
Dihydrocodeine bitartrate is secreted into human milk. In women with normal dihydrocodeine metabolism (normal CYP2D6 activity), the amount of dihydrocodeine secreted into human milk is low and dose-dependent. However, some women are ultra-rapid metabolizers of dihydrocodeine. These women achieve higher-than-expected serum levels of dihydrocodeine’s active metabolite, dihydromorphine, leading to higher-than-expected levels of dihydromorphine in breast milk and potentially dangerously high serum dihydromorphine levels in their breastfed infants. Therefore, maternal use of dihydrocodeine can potentially lead to serious adverse reactions, including death, in nursing infants.
The risk of infant exposure to dihydrocodeine and morphine through breast milk should be weighed against the benefits of breastfeeding for both the mother and baby. Caution should be exercised when dihydrocodeine is administered to a nursing woman. If a dihydrocodeine containing product is selected, the lowest dose should be prescribed for the shortest period of time to achieve the desired clinical effect. Mothers using dihydrocodeine should be informed about when to seek immediate medical care and how to identify the signs and symptoms of neonatal toxicity, such as drowsiness or sedation, difficulty breastfeeding, breathing difficulties, and decreased tone, in their baby. Nursing mothers who are ultra-rapid metabolizers may also experience overdose symptoms such as extreme sleepiness, confusion or shallow breathing. Prescribers should closely monitor mother-infant pairs and notify treating pediatricians about the use of dihydrocodeine-containing products during breastfeeding [see Warnings].
Dihydrocodeine bitartrate, acetaminophen and caffeine are also excreted in breast milk in small amounts. Because of the potential for serious adverse reactions in nursing infants from this combination product, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.
Safety and effectiveness of acetaminophen, caffeine and dihydrocodeine bitartrate tablets in pediatric patients have not been established.
Respiratory depression and death have occurred in children with obstructive sleep apnea who received codeine in the post-operative period following tonsillectomy and/or adenoidectomy and had evidence of being ultra-rapid metabolizers of codeine (i.e., multiple copies of the gene for cytochrome P450 isoenzyme CYP2D6 or high morphine concentrations). These children may be particularly sensitive to the respiratory depressant effects of codeine that has been rapidly metabolized to morphine.
Dihydrocodeine-containing products are contraindicated for post-operative pain management in all pediatric patients undergoing tonsillectomy and/or adenoidectomy [see Contraindications].
Acetaminophen, Caffeine and Dihydrocodeine Bitartrate Tablets should be given with caution to the elderly.
Acetaminophen, caffeine and dihydrocodeine bitartrate tablets should be given with caution to patients with hepatic insufficiency. Since dihydrocodeine is metabolized by the liver and since acetaminophen potentially causes hepatotoxicity, the effects of this combination product should be monitored closely in such patients.
Acetaminophen, caffeine and dihydrocodeine bitartrate tablets should be used with caution and at reduced dosage in the presence of impaired renal function.
Pancreatic/Biliary Tract Disease:
Opioids may cause spasms of the sphincter of Oddi and should be used with caution in patients with biliary tract disease including pancreatitis.
