For patients with acute upper respiratory tract infections, a combination cold preparation that relieves the symptoms of many colds can be used. A combination cold preparation containing pseudoephedrine hydrochloride and paracetamol is more effective in treating patients with symptoms of nasal congestion, itchy nose, sneezing and runny nose. It should be noted that medication should always be taken at a regular hospital under the guidance of a doctor and on time and in the right amount to ensure safety.
