It sounds like I am going to be prescribed erythromycin, and I want to know what this drug does to the body. I was originally going to get penicillin but for some reason the doctor now mentioned erythromycin instead. What are the side effects of this antibiotic? What are the differences between erythromycin and penicillin?
You know, the usual suspects. The side effects of erythromycin are normally nausea and even vomiting, diarrhea of course, headaches, stomach upsets and abdominal pain and unlike other antibiotics, these side effects are very common in erythromycin. It has also been said that erythromycin is linked to deafness, but that is rare.
