Patient was educated on the side effects of using Erythromycin as follows:
- Nausea and vomiting
 
- This is the most common side effect of Erythromycin. Taking the antibiotic with some food and water can minimize the effects of nausea and vomiting.
 
- Diarrhea
 
- Human intestines have a lot of bacteria, both good and bad, living in a sensitive balance with each other.
 - This helps maintain the normal natural intestinal environment.
 - Erythromycin works by killing the bacteria. While doing this, Erythromycin does not differentiate between good and bad bacteria.
 - Consequently, apart from killing the bad infectious bacteria, Erythromycin also kills the good bacteria in the intestinal system, thus compromising the balance between good and bad bacteria.
 - This can result in reduction in the number of good bacteria and increase in the number of Erythromycin resistant bad bacteria, leading to irritation of the intestinal mucosa and diarrhea.
 - Diarrhea secondary to the clostridium difficile bacteria in the intestines, is a standard example for this.
 
- Renal damage
 
- Long term Erythromycin intake can lead to renal damage, thus compromising kidney function.
 - Renal injury and altered kidney function can result in increased creatinine levels in the body, accumulation of other wastes resulting in altered levels of consciousness, and reduced urine formation.
