Codeine Syrup

Codeine syrup is an opioid-containing prescription medicine that may be used for certain cough-related conditions or pain, depending on the specific formulation and the laws and prescribing guidelines in the country where it is supplied. Because codeine can cause sedation, respiratory depression, misuse, and dependence, it should only be used as directed by a qualified healthcare professional.

What Is Codeine Syrup?

Codeine is an opioid medication that acts on the central nervous system. In some prescription cough formulations, it is used as an antitussive to reduce coughing. Other formulations may contain codeine for pain relief, sometimes combined with other active ingredients.

Different products can contain different concentrations and additional medicines. Therefore, the product name and strength should always be checked before use.

Codeine Syrup Uses

Depending on the formulation, codeine may be prescribed for:

• Relief of certain types of cough
• Short-term treatment of moderate pain in selected circumstances
• Symptoms where an opioid-containing medicine has been specifically determined to be appropriate

Codeine is not suitable for every cough or pain condition. A healthcare professional should evaluate the underlying cause of symptoms before recommending an opioid-containing medicine.

Codeine Syrup Side Effects

Possible side effects of codeine include:

• Drowsiness
• Dizziness
• Nausea or vomiting
• Constipation
• Dry mouth
• Confusion
• Reduced alertness
• Slow or shallow breathing

Serious breathing problems can occur, particularly after excessive doses or when codeine is combined with alcohol or other medicines that cause sedation.

Emergency medical attention is necessary if a person develops severe difficulty breathing, cannot be awakened, becomes extremely confused, or shows other signs of a potentially life-threatening reaction or overdose.

Codeine and Drug Interactions

Codeine can interact with other medicines and substances. Combining opioids with alcohol, benzodiazepines, sleeping medicines, or other central nervous system depressants can substantially increase sedation and the risk of respiratory depression.

Tell your doctor or pharmacist about all prescription medicines, over-the-counter products, and supplements you use before taking a codeine-containing medicine.

Is Codeine Addictive?

Codeine has the potential to cause opioid misuse, physical dependence, and addiction. The risk can increase with prolonged or inappropriate use.

Use codeine only according to the prescribed instructions. Never share an opioid prescription with another person, and keep the medicine securely stored away from children and others who could accidentally or intentionally take it.

Codeine vs. Hydrocodone

Codeine and hydrocodone are different opioid medications. They should not be treated as interchangeable medicines.

Hydrocodone is a semi-synthetic opioid that is chemically related to codeine and has historically been used as an analgesic and antitussive. The fact that the medicines are chemically related does not mean that they have identical effects, strengths, dosing requirements, or safety profiles.

A healthcare professional should determine which medication, if any, is appropriate for a particular patient.

Promethazine and Codeine Syrup

Some prescription cough formulations combine promethazine and codeine. Promethazine is an antihistamine with sedating properties, while codeine is an opioid.

Because both ingredients can cause central nervous system depression, the combination can produce significant drowsiness and may increase safety risks. It should be taken only according to the applicable prescription and official product information.
