Phenaphen with Codeine tablets are indicated for the relief of mild to moderately severe pain.
This product should not be administered to patients who have previously exhibited hypersensitivity to codeine or Phenaphen with Codeine.
In the presence of head injury or other intracranial lesions, the respiratory depressant effects of codeine and other narcotics may be markedly enhanced, as well as their capacity for elevating cerebrospinal fluid pressure. Narcotics also produce other CNS depressant effects, such as drowsiness, that may further obscure the clinical course of the patients with head injuries.
Codeine or other narcotics may obscure signs on which to judge the diagnosis or clinical course of patients with acute abdominal conditions. Codeine is habit-forming and potentially abusable. Consequently, the extended use of this product is not recommended.
Phenaphen with Codeine tablets should be prescribed with caution in certain special-risk patients, such as the elderly or debilitated, and those with severe impairment of renal or hepatic function, head injuries, elevated intracranial pressure, acute abdominal conditions, hypothyroidism, urethral stricture, Addison’s disease, or prostatic hypertrophy.
Codeine may impair mental and/or physical abilities required for the performance of potentially hazardous tasks such as driving a car or operating machinery. Such tasks should be avoided while taking this product.
Alcohol and other CNS depressants may produce an additive CNS depression, when taken with this combination product, and should be avoided. Codeine may be habit-forming. Patients should take the drug only for as long as it is prescribed, in the amounts prescribed, and no more frequently than prescribed.
In patients with severe hepatic or renal disease, effects of therapy should be monitored with serial liver and/or renal function tests.
This drug may enhance the effects of: other narcotic analgesics, alcohol, general anesthetics, tranquilizers such as chlordiazepoxide, sedative-hypnotics, or other CNS depressants, causing increased CNS depression.
Codeine may increase serum amylase levels.
Phenaphen with Codeine may produce false-positive test results for urinary 5-hydroxyindoleacetic acid.
No adequate studies have been conducted in animals to determine whether Phenaphen with Codeine and codeine have a potential for carcinogenesis or mutagenesis. No adequate studies have been conducted in animals to determine whether Phenaphen with Codeine has a potential for impairment of fertility.
Phenaphen with Codeine and codeine have been found to have no mutagenic potential using the Ames Salmonella-Microsomal Activation test, the Basc test on Drosophila germ cells, and Micronucleus test on mouse bone marrow.
Codeine: A study in rats and rabbits reported no teratogenic effect of codeine administered during the period of organogeneses in doses ranging from 5 to 120 mg/kg. In the rat, doses at the 120 mg/kg level, in the toxic range for the adult animal, were associated with an increase in embryo resorption at the time of implantation. In another study a single 100 mg/kg dose of codeine administered to pregnant mice reportedly resulted in delayed ossification in the offspring.
There are no adequate and well-controlled studies in pregnant women. Phenaphen with Codeine should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
Dependence has been reported in newborns whose mothers took opiates regularly during pregnancy. Withdrawal signs include irritability, excessive crying, tremors, hyperreflexia, fever, vomiting, and diarrhea. These signs usually appear during the first few days of life.
Narcotic analgesics cross the placental barrier. The closer to delivery and the larger the dose used, the greater the possibility of respiratory depression in the newborn. Narcotic analgesics should be avoided during labor if delivery of a premature infant is anticipated. If the mother has received narcotic analgesics during labor, newborn infants should be observed closely for signs of respiratory depression. Resuscitation may be required. The effect of codeine, if any, on the later growth, development, and functional maturation of the child is unknown.
Phenaphen with Codeine and codeine are excreted in breast milk in small amounts, but the significance of their effects on nursing infants is not known. Because of the potential for serious adverse reactions in nursing infants from Phenaphen with Codeine and codeine, 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.
The most frequently reported adverse reactions are drowsiness, lightheadedness, dizziness, sedation, shortness of breath, nausea and vomiting. These effects seem to be more prominent in ambulatory than in non-ambulatory patients, and some of these adverse reactions may be alleviated if the patient lies down.
Other adverse reactions include allergic reactions, euphoria, dysphoria, constipation, abdominal pain, pruritus, rash, thrombocytopenia, agranulocytosis. At higher doses codeine has most of the disadvantages of morphine including respiratory depression.
Phenaphen with Codeine tablets are classified as a Schedule III controlled substance.
Codeine can produce drug dependence of the morphine type and, therefore, has the potential for being abused. Psychological dependence, physical dependence. and tolerance may develop upon repeated administration and it should be prescribed and administered with the same degree of caution appropriate to the use of other oral narcotic medications.
Following an acute overdosage, toxicity may result from codeine or Phenaphen with Codeine.
Codeine: Toxicity from codeine poisoning includes the opioid triad of: pinpoint pupils, depression of respiration, and loss of consciousness. Convulsions may occur.
A single or multiple overdose with Phenaphen with Codeine and codeine is a potentially lethal polydrug overdose, and consultation with a regional poison control center is recommended.
Immediate treatment includes support of cardiorespiratory function and measures to reduce drug absorption. Vomiting should be induced mechanically, or with syrup of ipecac, if the patient is alert. Oral activated charcoal (1 g/kg) should follow gastric emptying. The first dose should be accompanied by an appropriate cathartic. If repeated doses are used, the cathartic might be included with alternate doses as required. Hypotension is usually hypovolemic and should respond to fluids. Vasopressors and other supportive measures should be employed as indicated. A cuffed endo-tracheal tube should be inserted before gastric lavage of the unconscious patient and, when necessary, to provide assisted respiration. Meticulous attention should be given to maintaining adequate pulmonary ventilation. In severe cases of intoxication, peritoneal dialysis, or preferably hemodialysis may be considered. If hypoprothrombinemia occurs due to Phenaphen with Codeine overdose, vitamin K should be administered intravenously. Naloxone, a narcotic antagonist, can reverse respiratory depression and coma associated with opioid overdose. Naloxone hydrochloride 0.4 mg to 2 mg is given parenterally. Since the duration of action of codeine may exceed that of the naloxone, the patient should be kept under continuous surveillance and repeated doses of the antagonist should be administered as needed to maintain adequate respiration. A narcotic antagonist should not be administered in the absence of clinically significant respiratory or cardiovascular depression. If the dose of Phenaphen with Codeine may have exceeded 140 mg/kg, acetylcysteine should be administered as early as possible. Serum Phenaphen with Codeine levels should be obtained, since levels four or more hours following ingestion help predict Phenaphen with Codeine toxicity. Do not await Phenaphen with Codeine assay results before initiating treatment. Hepatic enzymes should be obtained initially, and repeated at 24-hour intervals. Methemoglobinemia over 30% should be treated with methylene blue by slow intravenous administration.
Phenaphen with Codeine: toxic dose l0 g
Codeine: toxic dose 240 mg
Dosage should be adjusted according to severity of pain and response of the patient.
The usual adult dosage is: Single Doses (range) Maximum 24 Hour DoseCodeine Phosphate 15 mg to 60 mg 360 mgAcetaminophen 300 mg to 1000 mg 4000 mg The usual dose of codeine phosphate in children is 0.5 mg/kg. Doses may be repeated up to every 4 hours. The prescriber must determine the number of tablets per dose, and the maximum number of tablets per 24 hours based upon the above dosage guidance. This information should be conveyed in the prescription. It should be kept in mind, however, that tolerance to codeine can develop with continued use and that the incidence of untoward effects is dose related. Adult doses of codeine higher than 60 mg fail to give commensurate relief of pain but merely prolong analgesia and are associated with an appreciably increased incidence of undesirable side effects. Equivalently high doses in children would have similar effects.
