Codeine is used to treat mild to moderate pain. [4] It is commonly used to treat post-surgical dental pain. [13]Weak evidence indicates that it is useful in cancer pain, but it may have increased adverse effects, especially constipation, compared to other opioids. [14]
Those allergic to codeine may also be allergic to oxycodone. [16] Use of oxycodone in early pregnancy appears relatively safe. [16] Opioid withdrawal may occur if rapidly stopped. [16] Oxycodone acts by activating the μ-opioid receptor. [19] When taken by mouth, it has roughly 1.5 times the effect of the equivalent amount of morphine. [20]
Opioid-induced hyperalgesia (OIH) or opioid-induced abnormal pain sensitivity, also called paradoxical hyperalgesia, is an uncommon condition of generalized pain caused by the long-term use of high dosages of opioids [1] such as morphine, [2] oxycodone, [3] and methadone.
Codeine/paracetamol, also called codeine/acetaminophen and co-codamol, is a compound analgesic, comprising codeine phosphate and paracetamol (acetaminophen). Codeine/paracetamol is used for the relief of mild to moderate pain when paracetamol or non-steroidal anti-inflammatory drugs (NSAIDs; such as ibuprofen, aspirin, and naproxen) alone do not sufficiently relieve symptoms.
While all opioids cause constipation, there are some differences between drugs, with studies suggesting tramadol, tapentadol, methadone and fentanyl may cause relatively less constipation, while with codeine, morphine, oxycodone or hydromorphone constipation may be comparatively more severe.
Codeine analogues of morphine-based drugs often serve as prodrugs of the stronger drug, as in codeine and morphine, hydrocodone and hydromorphone, oxycodone and oxymorphone, nicocodeine and nicomorphine, dihydrocodeine and dihydromorphine, etc.
