II. Indications

Opioid Analgesic

-
Cough Suppressant (Antitussive)
- Often abused (other agents are preferred)

- References
- FDA Drug Safety Communication (4-20-2017)
IV. Preparations: Codeine 30 with Acetaminophen 300 tablets
- Dose: 1-2 tablets orally every 4-6 hours
- Avoid due to low efficacy and increased toxicity risk
V. Preparations: Acetaminophen with Codeine Elixir (not recommended)
- Risk of Opioid induced respiratory depression and other Overdose adverse effects (especially in children)
- Deaths in children have occurred with codeine Analgesics following Tonsillectomy and adenoidectomy
- Resulted in FDA black box warning in 2013
- (2013) Presc Lett 20(4): 21
- FDA Drug Safety Communication
- Components
- Acetaminophen (120 mg/5ml Elixir)
- Codeine (12 mg/5ml Elixir)
- Dosing
- Age 3 to 6 years: 5 ml/dose every 4 hours prn
- Age 7 to 12 years: 10 ml/dose every 4 hours prn
VI. Efficacy
- Acetaminophen is a safe and effective Analgesic
- Codeine is no more effective than standard NSAIDs
- Naprosyn is as effective in post-operative pain
- Ouellette (1986) Curr Ther Res 39(5):839 [PubMed]
- Busquets (1988) Curr Ther Res 43(2):311 [PubMed]
- Codeine offers no significant benefit to Tylenol
- Adding Codeine to Tylenol increases adverse effects
- Codeine 60 mg equivalent to Aspirin 650 mg
VII. Precautions
- Weak Analgesic, with abuse potential and risk of death in ultrarapid CYP2D6 metabolizers
- Other agents are preferred: NSAIDs, Acetaminophen, short acting Morphine, Hydrocodone, Oxycodone
- Non-responders to Codeine: 10% of patients
- Lack endogenous enzyme to convert to Morphine
- Risk of Opioid induced respiratory depression and other Overdose adverse effects (especially in children)
- Associated with CYP2D6 ultrarapid metabolization (fast metabolizers) found in 5-30% (depending on ethnicity)
- Deaths in children have occurred with codeine Analgesics following Tonsillectomy and adenoidectomy
- Deaths likely related to ultrarapid metabolizers with underlying airway disorders (e.g. Sleep Apnea)
- Resulted in FDA black box warning in 2013
- AAP recommends no use of Codeine products under age 18 years old

Ontology: Codeine (C0009214)
Definition (NCI) | A naturally occurring phenanthrene alkaloid and opioid agonist with analgesic, antidiarrheal and antitussive activities. Codeine mimics the actions of endogenous opioids by binding to the opioid receptors at many sites within the central nervous system (CNS). Stimulation of mu-subtype opioid receptors results in a decrease in the release of nociceptive neurotransmitters such as substance P, GABA, dopamine, acetylcholine and noradrenaline; in addition, the codeine metabolite morphine induces opening of G-protein-coupled inwardly rectifying potassium (GIRK) channels and blocks the opening of N-type voltage-gated calcium channels, resulting in hyperpolarization and reduced neuronal excitability. Stimulation of gut mu-subtype opioid receptors results in a reduction in intestinal motility and delayed intestinal transit times. Antitussive activity is mediated through codeine's action on the cough center in the medulla. |
Definition (MSH) | An opioid analgesic related to MORPHINE but with less potent analgesic properties and mild sedative effects. It also acts centrally to suppress cough. |
Definition (CSP) | opioid analgesic related to morphine but with less potent analgesic properties and mild sedative effects; also acts centrally to suppress cough. |

Definition (NCI) | A synthetic p-aminophenol derivative combined with codeine, with anti-inflammatory and analgesic activites. Acetaminophen with codeine is used against inflammatory conditions, fever, and pain. Codeine is an opium alkaloid with analgesic properties. Acetaminophen appears to inhibit prostaglandin biosynthesis in the central nervous system and less in peripheral tissues. |
