Codeine Side Effects

Codeine is a member of the drug class opiates. Opiates include all naturally occurring drugs with morphine-like effects such as codeine and all semi and fully synthetic drugs with morphine-like effects such as heroin and meperidine (Demerol). Addiction is a major risk with prolonged use (over 2-3 weeks) of Codeine.

Codeine induces an "opioid analgesia" by altering the perception of pain at the spinal cord and brain. It also affects emotional responses to pain. Codeine has stimulating effects as well because it blocks inhibitory neurotransmitters. Repeated use of Codeine can cause long-term changes in the way the nervous system functions.
