Tylenol with Codeine #4 - 60 mg of codeine per tablet.
11-6. CAUTIONS OF NARCOTIC USE
a. Narcotics should not be used in patients experiencing any form of respiratory
depression (that is, asthma).
b. Narcotics cause an increase in intracranial pressure (pressure within the
skull). Therefore, they should not be used in the presence of head injuries.
c. Narcotics should be used cautiously in combination with other drugs that
depress the central nervous system.
11-7. NARCOTIC ANTAGONISM
a. Explanation. As previously mentioned, narcotics depress the respiratory
system. Sometimes it is necessary to reverse this respiratory depression (that is,
overdose of narcotics) in order to save a patient's life.
b. Naloxone (Narcan). Naloxone (Narcan) is the only true narcotic antagonist
in that it does not possess agonist or morphine-like properties and, most importantly, it
has no respiratory depressant action in therapeutic doses. Because it does not depress
respiration, naloxone is the drug of choice in the treatment of respiratory depression of
unknown causes, but which is suspected of being produced by a narcotic. Narcan is
given in a usual dose of 0.4 mg IM, SC, or IV, and may produce some nausea and
vomiting. It is not a controlled substance, and is available as an injection, 0.4 mg/ml or
0.2 mg/ml for pediatric use.
c. Indications/Uses. Naloxone (Narcan) is indicated/used to reverse
respiratory depression caused by natural and synthetic narcotics, pentazocine
(Talwin), and propoxyphene (Darvon). It is not effective against the respiratory
depression caused by the barbiturates or benzodiazepines. Naloxone is a competitive
