How Cetirizine + Dextromethorphan + Phenylephrine works
Cetirizine + Dextromethorphan + Phenylephrine is a multi-action cold, flu, and allergy relief combination.
Cetirizine, an antihistamine, works by blocking histamine. Histamine is a substance our bodies produce during an allergic reaction that can lead to symptoms like a runny nose or sneezing. By blocking it, Cetirizine helps reduce these symptoms.
Dextromethorphan is a cough suppressant that acts on the brain's cough centre. It helps to decrease the urge to cough, particularly beneficial for dry, non-productive coughs.
Phenylephrine is a decongestant that reduces inflammation and swelling in the nasal passages. It does this by constricting the small blood vessels in the nose. This action helps mucus drain and relieves nasal congestion.
Together, these three active ingredients help manage multiple symptoms associated with common cold, flu, and allergies like sneezing, runny nose, itchiness, coughing, and nasal or sinus congestion.
