What is acetaminophen, dextromethorphan, guaifenesin, and phenylephrine (Cold & Cough PE, Non-Pseudo Cold Relief, Phenflu DM, Sudafed PE Cold & Cough, Tylenol Cold Head Congestion Severe, Tylenol Cold Multi-Symptom Severe, Tylenol Cold Multi-Symptom Severe Daytime)?
Guaifenesin is an expectorant. It helps loosen congestion in your chest and throat, making it easier to cough up.
Phenylephrine is a decongestant. It constricts (shrinks) blood vessels (veins and arteries). This reduces the blood flow to certain areas, which decreases swelling and allows nasal and respiratory (breathing) passages to open up.
The combination of acetaminophen, dextromethorphan, guaifenesin, and phenylephrine is used to treat stuffy nose, sinus congestion, cough, chest congestion, and pain or fever caused by the common cold or flu, or conditions such as bronchitis or sinusitis.
