Naloxone , a narcotic antagonist , can reverse respiratory depression and coma associated with opioid overdose. 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.
Serum acetaminophen levels should be obtained, since levels four or more hours following ingestion help predict acetaminophen toxicity. Do not await acetaminophen assay results before initiating treatment.
