Codeine is an opioid cough suppressant, meaning it reduces the urge to cough. It is available in prescription cough syrups, often in combination with other active ingredients.
What cough syrups contain codeine?
Several prescription cough syrups contain codeine. Common examples include:
* Promethazine DM with Codeine: This syrup typically combines codeine with promethazine (an antihistamine) and dextromethorphan (a cough suppressant).
* Hydrocodone/Homatroprine: While hydrocodone is a different opioid, it is also used for cough suppression.
* Prescription Cough Syrups with Guaifenesin and Codeine: Some formulations pair codeine with guaifenesin, an expectorant that helps thin mucus.
It is important to note that codeine-containing cough syrups are controlled substances due to the potential for abuse and dependence. They are available only by prescription from a healthcare provider.
Why is codeine used in cough syrups?
Codeine works by acting on the cough center in the brain, reducing the sensitivity of the cough reflex. This effect helps to suppress persistent, dry coughs that can be disruptive and uncomfortable [1].
What are the risks associated with codeine cough syrup?
Codeine is an opioid, and its use carries risks, including:
* Dependence and Addiction: Regular use can lead to physical dependence and addiction.
* Respiratory Depression: Opioids can slow breathing, which can be dangerous, especially at higher doses or when combined with other sedatives.
* Drowsiness and Dizziness: These are common side effects that can impair the ability to drive or operate machinery.
* Constipation: A frequent side effect of opioid use.
Due to these risks, codeine cough syrups are typically prescribed for short-term use and for severe coughs that do not respond to other treatments.

Are there non-codeine alternatives for cough relief?
Yes, there are several alternatives to codeine for cough relief. These include over-the-counter cough suppressants like dextromethorphan, which acts on the cough center in the brain but is not an opioid. Expectorants, such as guaifenesin, can help thin mucus, making it easier to cough up. Non-pharmacological remedies like honey, lozenges, and humidifiers can also provide relief for cough symptoms [1].
How is codeine regulated?
Codeine is a Schedule V controlled substance in the United States, and its distribution is regulated by the Drug Enforcement Administration (DEA). In many other countries, it is also a prescription-only medication. Regulations aim to balance its therapeutic use with measures to prevent misuse and diversion [3].
