Codeine is an opioid pain reliever and cough suppressant found in various prescription medications. It is often combined with other ingredients, such as acetaminophen or ibuprofen, to enhance its pain-relieving effects.
What are common prescription medications containing codeine?
Several combination medications include codeine. For instance, acetaminophen and codeine is a common prescription for mild to moderate pain [1]. Examples of brand names for this combination include Tylenol with Codeine and Capital-de-T. Another combination, guaifenesin and codeine, is used to relieve cough and chest congestion [2]. This is often found under brand names like Robitussin AC and Mytussin AC.
Can I buy medications with codeine over-the-counter?
In the United States, medications containing codeine generally require a prescription [1][2]. While some formulations might have been available over-the-counter in the past, current regulations typically classify them as prescription-only due to their opioid nature and potential for misuse.
What are the risks associated with codeine medications?
Codeine, being an opioid, carries risks of dependence, addiction, and overdose [3]. Side effects can include drowsiness, dizziness, nausea, constipation, and respiratory depression, especially at higher doses or when combined with other central nervous system depressants [3]. It is crucial to use these medications only as prescribed by a healthcare professional and to store them securely to prevent diversion.
How does codeine work for pain and cough?
Codeine acts on the central nervous system to relieve pain and suppress cough [4]. In the body, codeine is converted to morphine, which then binds to opioid receptors, altering the perception of pain and reducing the urge to cough [4]. The effectiveness of codeine can vary between individuals due to genetic differences in how their bodies metabolize the drug.
