A cold and cough that stops quickly can usually be improved by drinking plenty of water and using cough suppressants. 1. If a cough develops as a result of a cold, no special treatment is usually needed. Colds are self-limiting and usually recover on their own. Resting during the course of the illness and drinking plenty of fluids can help relieve the sore throat caused by coughing on the one hand, and speed up the metabolism on the other, which can improve the symptoms. 2. However, if the cough is more severe, and the severe dry cough affects rest and work, it is necessary to control the cough with cough suppressants, such as dextromethorphan, etc. If the cough is accompanied by mucous sputum that is not easy to cough up, it is usually self-limiting. If accompanied by mucus sputum is not easy to cough out, you can use aminobromine and other medications, which can significantly control the cough symptoms, improve the general state, and avoid further aggravation of symptoms. If the symptoms do not improve or even worsen after a cold, it is recommended to seek medical advice and use medication under the guidance of a doctor.
