When we talk about pneumonia, we usually mean that the symptoms gradually disappear. Because the natural course of pneumonia itself is only about 1-2 weeks, the body temperature can drop or gradually subside after 5-10 days of illness, and after treatment with effective antibacterial drugs, the body temperature will return to normal within 1-3 days, and other accompanying symptoms, such as cough and sputum, will gradually decrease or disappear. In fact, the absorption process of pneumonia is relatively slow, because most of the cases can be completely dissipated only after 3-4 weeks after the onset of the disease. In this case, you can continue to take oral phlegm-suppressing drugs, such as aminoglutethimide hydrochloride and acetylcysteine effervescent tablets, for phlegm-suppressing treatment.
