Codeine is also effective as a cough suppressant, as it acts on the brain's cough center and reduces the urge to cough. It is commonly prescribed for dry, non-productive coughs that may result from conditions like the common cold or respiratory infections.

While codeine can provide effective pain relief and alleviate coughing, it carries certain risks and side effects. Common side effects include drowsiness, dizziness, constipation, and nausea. Codeine can also cause respiratory depression, especially when taken in higher doses or mixed with other depressants like alcohol. Therefore, it is important to follow the prescribed dosage and avoid activities that require alertness when taking codeine.

Codeine is classified as a controlled substance due to its potential for abuse and dependence. Prolonged or improper use can lead to addiction, tolerance, and withdrawal symptoms when the drug is discontinued. It is crucial to use codeine only as prescribed and to consult with a healthcare professional if any concerns or issues arise.
