Temporary relief of nasal and sinus congestion, sneezing, runny nose, itchy or watery eyes, and other allergic symptoms associated with the common cold, hay fever, or other upper respiratory allergies
The antihistamines (chlorpheniramine and pyrilamine) block histamine receptors to reduce allergic symptoms, while phenylpropanolamine constricts blood vessels in the nasal passages to reduce swelling and congestion. Ascorbic acid may support immune function during illness.
