IMPORTANT INFORMATION ABOUT TUZISTRA XR


INDICATIONS AND USAGE


TUZISTRA XR is a combination of codeine, an opiate agonist antitussive, and chlorpheniramine, a histamine-1 (H1) receptor antagonist indicated for relief of cough and symptoms associated with upper respiratory allergies or a common cold.

IMPORTANT SAFETY INFORMATION


WARNING

DEATH RELATED TO ULTRA-RAPID METABOLISM OF CODEINE TO MORPHINE and RISKS FROM CONCOMITANT USE WITH BENZODIAZEPINES OR OTHER CNS DEPRESSANTS


Ultra-Rapid Metabolism

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 a CYP2D6 polymorphism.


Concomitant Use with Benzodiazepines, CNS Depressants

Concomitant use of opioids with benzodiazepines or other central nervous system (CNS) depressants, including alcohol, may result in profound sedation, respiratory depression, coma, and death. Avoid use of opioid cough medications in patients taking benzodiazepines, other CNS depressants, or alcohol.


CONTRAINDICATIONS

Postoperative pain management of children undergoing tonsillectomy and/or adenoidectomy.

Patients with known hypersensitivity to codeine, chlorpheniramine, or any of the product components of TUZISTRA XR.


WARNINGS AND PRECAUTIONS


Risk of death in individuals who are ultra-rapid metabolizers: Conversion of codeine into its active metabolite, morphine, may occur more rapidly and completely resulting in higher than expected morphine levels and respiratory depression or death. Some individuals CYP2D6 genotype, which prevalence varies widely, and is estimated at 0.5 to 1% in Chinese and Japanese, 0.5 to 1% in Hispanics, 1 to 10% in Caucasians, 3% in African Americans, and 16 to 28% in North Africans, Ethiopians, and Arabs.

Risks from concomitant use with benzodiazepines or other CNS depressants: Concomitant use of opioids with benzodiazepines or other CNS depressants, including alcohol, may result in profound sedation, respiratory depression, coma, and death.

Dose-related respiratory depression: Use with caution, including when used postoperatively, in patients with pulmonary disease or shortness of breath, or whenever ventilator function is depressed. Overdose of codeine in adults has been associated with fatal respiratory depression, and the use of codeine in children, have been associated with fatal respiratory depression. If respiratory depression occurs, discontinue the drug and use naloxone hydrochloride or other supportive measures as necessary.

Drug dependence: Prescribe with caution that is appropriate to the use of other opioids.

Head injury and increased intracranial pressure: Avoid in patients with head injury, intra-cranial lesions, or increased intracranial pressure.

Activities requiring mental alertness: Avoid engaging in hazardous tasks requiring complete mental alertness such as driving or operating heavy machinery. Avoid concurrent use of alcohol or other central nervous system depressants.

Obstructive bowel disease: Chronic use of opioids, including codeine, may result in constipation or chronic obstructive bowel disease, especially in patients with underlying intestinal motility disorders.

Acute abdominal conditions: Use with caution in patients with acute abdominal conditions.

Dosing: Measure dose with an accurate milliliter measuring device; a household teaspoon is not accurate and could lead to over dosage, resulting in serious adverse reactions.

Special risk patients: Caution in elderly patients and those with asthma, hypothyroidism, Addison's disease, prostatic hypertrophy or urethral stricture.


ADVERSE REACTIONS


Common adverse reactions of TUZISTRA XR include: nausea and vomiting, constipation, abdominal distension, abdominal pain, blurred vision, diplopia, visual disturbances, confusion, dizziness, depression, drowsiness, sedation, headache, euphoria, facial dyskinesia, feeling faint, light-headedness, general feeling of discomfort or illness, excitability, nervousness, agitation, restlessness, somnolence, insomnia, dyskinesia, irritability, tremor.
