The common cold is caused by typical viruses or bacteria that infect the upper respiratory tract. Following a cold, the airways can become inflamed, leading to the secretion of mucus, consequently causing symptoms like a runny nose, sneezing, coughing, and phlegm production. Currently, many multi-ingredient cold medications on the market not only treat cold symptoms such as runny nose and nasal congestion but also effectively alleviate coughs caused by the cold. For example, medications like Phenol Anisamine Methylamine tablets and Acetaminophen Codeine tablets effectively treat coughs induced by the common cold. (Please use medication under the guidance of a professional physician.)
