Other Comments

Administration advice:
-Take orally with or without food
-Oral measuring devices should be used to ensure accuracy in dosing; a household teaspoon should not be considered an accurate measuring device

Storage requirements:
-Protect from moisture and light

General:
-Patients who are ultra-rapid metabolizers of codeine due to a CYP450 2D6 polymorphism, will convert codeine more rapidly and completely to morphine resulting in unexpectedly high morphine levels, which may be life-threatening.
-Codeine use is contraindicated in the postoperative period in children who have undergone tonsillectomy and/or adenoidectomy.

Monitoring:
-Cardiovascular: Monitor for signs of hypotension, especially in those whose blood pressure is compromised
-Respiratory: Monitor for respiratory depression
-Gastrointestinal: Monitor for constipation and decreased bowel motility
-Patients should be monitored for the development of addiction, abuse, or misuse.

Patient advice:
-Patients should understand that codeine use can result in addiction, abuse, and misuse.
-Patients should understand risks of life-threatening respiratory depression and when this risk is greatest; patients should be aware that a genetic mutation may result in greater codeine toxicity in some patients; breastfed infants of women who have this genetic mutation are also at risk.
-Patients should be instructed to pay close attention to drugs labels, particularly to the active ingredients section to ensure they are not receiving duplicate therapy.
-Women who are breastfeeding, pregnant, or planning to become pregnant should speak to their healthcare provider before using this product.
-This drug may cause drowsiness, dizziness, or impair thinking or motor skills; patients should avoid driving or operating machinery while taking this drug.
-Concomitant use of alcohol, sedatives, and tranquilizers may increase drowsiness; patients should avoid alcohol and consult with their healthcare provider regarding concomitant use of CNS depressants.
