It is true that patients with severe pneumonia are more likely to be cured by combining the use of immunoglobulin while actively fighting infection. Immunoglobulin is a kind of globulin with antibody activity, which can improve the body’s immunity. Pneumonia patients who play immunoglobulin can promote the recovery of the disease, but it is not possible to rely solely on immunoglobulin to cure pneumonia. If the pneumonia is more serious, need to use drugs according to the type of pathogen, for bacterial pneumonia, can use penicillin or cephalosporin antibiotic drugs, such as penicillin V potassium, cephalosporin benzyl and so on. For mycoplasma pneumonia, macrolide antibiotic drugs can be used, such as roxithromycin, azithromycin, and with immunoglobulin. However, if the pneumonia is mild, immunoglobulin is usually not needed. Pneumonia patients are advised to consult the doctor in time, and must cooperate with the doctor to take treatment, not to self-medicate arbitrarily.
