Cheratussin AC contains two key active ingredients: codeine and guaifenesin. Let’s explore how each works.
- Codeine: This is an opioid cough suppressant. Codeine acts on the brain to reduce the urge to cough. It’s important to note that codeine is a controlled substance, and its use should be strictly as directed by a doctor. Misuse can lead to serious health risks, including addiction. Guaifenesin: This is an expectorant. Guaifenesin thins and loosens mucus in the airways, making it easier to cough up and clear from your lungs. This helps relieve congestion associated with coughs.
The combined action of codeine and guaifenesin targets both the cough reflex and the mucus build-up, providing relief from the symptoms of a cough associated with the common cold or other upper respiratory tract infections.
Always follow the dosage instructions provided by your doctor or pharmacist. Do not exceed the recommended dose. If you experience any adverse reactions, stop using the medication and consult a healthcare professional immediately.

Remember: Codeine can cause drowsiness and dizziness. Avoid driving or operating machinery until you know how it affects you. Note: This medication may interact with other drugs. Inform your doctor or pharmacist about all medications, including over-the-counter drugs and herbal supplements, you are currently taking.
