What gastrointestinal side effects should a nurse be concerned about for a client taking erythromycin?

Erythromycin, an antibiotic commonly used to treat various infections, can have gastrointestinal side effects due to its mechanism of action. One of the most notable side effects is the potential for gastrointestinal upset, particularly vomiting. This occurs because erythromycin can stimulate gastrointestinal motility and increase the movement of food through the stomach and intestines, which can lead to discomfort and vomiting in some patients. Therefore, monitoring for signs of vomiting is essential for nurses caring for clients receiving this medication.

In contrast, drowsiness, rash, and headache are not typically associated with erythromycin use. These might occur with other medications or health conditions but are not primary concerns linked directly to this antibiotic. By focusing on gastrointestinal side effects, the nurse can better manage and mitigate the impact of medication side effects on the patient’s overall condition.
