General bacterial pneumonia, not very serious pneumonia, usually need to go through antibiotic treatment, such as penicillin, cephalosporin, after 2-3 days of medication to restore the body temperature to normal, you can continue to use drugs, the general course of treatment for 5-7 days. If you are allergic to penicillin, you can use anti-inflammatory drugs such as cotrimoxazole and erythromycin for treatment. But if for more stubborn bacteria, such as Staphylococcus aureus, and other pathogenic infections, such as fungal infections, in the use of separate anti-bacterial and anti-fungal drugs, it may take a month or even a month and a half to get better.
