Codeine and paracetamol

What are the uses of this medicine?

• Acetaminophen/Codeine is a pain medicine that contains an opioid (narcotic) that is used to manage mild to moderate pain, when other pain treatments such as non-opioid pain medicines do not treat your pain well enough or you cannot tolerate them.
• An opioid pain medicine that can put you at risk for overdose and death.
• Even if you take your dose correctly as prescribed, you are at risk for opioid addiction, abuse, and misuse that can lead to death.

How does this medicine work?

Codeine:

• Codeine is an opioid agonist relatively selective for the mu-opioid receptor, but with a much weaker affinity than morphine.
• The analgesic properties of codeine have been speculated to come from its conversion to morphine, although the exact mechanism of analgesic action remains unknown.

Acetaminophen:

• Acetaminophen (a seet" a min' oh fen), which is known as paracetamol in Europe, is an aminophenol that is believed to act centrally as an analgesic and antipyretic agent.
