When used together, these two medications can provide effective relief for symptoms such as cough, congestion, and runny nose. However, it is important to use this medication as directed by your healthcare provider, as misuse or overuse can lead to serious side effects.

Common side effects of Codeine and Chlorpheniramine may include drowsiness, dizziness, constipation, and dry mouth. It is important to avoid driving or operating heavy machinery while taking this medication, as it can impair your ability to perform these tasks safely.

If you experience any severe side effects such as difficulty breathing, chest pain, or confusion, it is important to seek medical attention immediately. Additionally, it is important to inform your healthcare provider of any other medications you are taking, as they may interact with Codeine and Chlorpheniramine.

Overall, Codeine and Chlorpheniramine can be an effective treatment option for relieving symptoms of the common cold and allergies. However, it is important to use this medication responsibly and under the guidance of a healthcare provider to ensure safe and effective treatment.
