It is used to treat such diseases as pneumonia caused by fungi, and streptococcus and syphilis infections, especially where the patient is allergic to penicillin.

Erythromycin

 

a macrolide antibiotic, the chief producer of which is the soil-inhabiting organism Streptomyces erythreus. Erythromycin is active against most grampositive bacteria (such as staphylococci, streptococci, and pneumococci), certain gram-negative bacteria (such as brucellae), rickettsiae, and large viruses. It fights staphylococci that are resistant to penicillin, antibiotics of the tetracycline group, and streptomycin. Erythromycin is used for treating pneumonia and other infectious diseases.

Recommended alternatives are erythromycin base, 250 mg orally four times a day for 14 days, or erythromycin ethylsuccinate, 800 mg orally four times a day for 7 days, or erythromycin ethylsuccinate 400 mg orally four times a day for 14 days; if the patient cannot tolerate erythromycin, amoxicillin can be tried, even though its efficacy is questionable.
