How does this medication work? What will it do for me?
Erythromycin ethylsuccinate belongs to the class of medications known as macrolide antibiotics. It works by killing the bacteria or preventing their growth. It is used to treat many bacterial infections, including chest infections such as pneumonia, skin infections, throat infections such as strep throat, diphtheria, ear infections, and certain sexually transmitted infections such as syphilis or chlamydia.
Erythromycin ethylsuccinate may also be used to prevent heart problems after dental work for people with heart disease.
Under normal circumstances, your infection should improve (e.g., reduced symptoms or temperature) within 24 to 48 hours. If this does not happen, call your doctor. Like other antibiotics, erythromycin ethylsuccinate is not effective against viruses such as those that cause the common cold.
