Used to temporarily relieve symptoms associated with the common cold, flu, and upper respiratory infections, including fever, headache, body aches, sore throat, cough, chest congestion, and nasal congestion.

Each ingredient works through a different mechanism: acetaminophen inhibits pain and fever signals in the nervous system; codeine acts on the brain's cough reflex to suppress coughing; guaifenesin thins and loosens mucus in the lungs and airways; and phenylephrine constricts blood vessels in the nasal passages to reduce swelling and congestion.

This medication contains codeine, an opioid that carries risks of dependence, drowsiness, and respiratory depression. It should not be combined with alcohol or other CNS depressants. Patients should avoid driving or operating machinery until they know how this medication affects them. Codeine is not recommended for children under 12 years old or for adolescents after certain surgeries. Due to the acetaminophen component, patients with liver disease should use caution. Always follow prescribed dosages carefully and consult a healthcare provider before use.
