First of all, there is a lot of phlegm after a cold. It is generally considered that there may be bronchitis or lung inflammation, which will lead to a lot of phlegm. Some anti-inflammatory drugs, such as amoxicillin or cephalosporin antibiotics and levofloxacin, can be used, and should be treated with drugs that clear the lungs and dissipate phlegm. Drink more warm boiled water, eat as light as possible, avoid spicy and stimulating food, and eat more pears, because pears can play the role of phlegm. We should eat less spicy and irritating food in our diet. If the effect is still not good after active treatment, we can take a chest X-ray for examination to rule out pneumonia. If pneumonia exists and the effect of drug treatment is not good, it can be treated by infusion in hospital, because the blood concentration of the drug given by infusion is relatively high, which can achieve the purpose of cure. Generally, the course of treatment is one to two weeks.
