Gastrointestinal

Gastrointestinal side effects have been reported the most frequently. These have included nausea (17.1%), cramping (9.1%), abdominal fullness (22.3%), vomiting (5.9%) and overall discomfort (19.1%).

A small percentage of patients who received PEG-ELS have reportedly experienced Mallory-Weiss tears of the esophagus and esophageal perforation. In addition, at least one case of rectal prolapse has been reported.^[Ref]

Mallory-Weiss tears are quite rare with administration of PEG-ELS. In one study it occurred in only 0.06% of over 3,000 patients.

Complete rectal prolapse was reported in a 71-year-old who had been given 4 L of PEG-ELS. The patient was observed for 2 days and had no recurrence of the prolapse.

During administration of PEG-ELS (4 liters) two deaths occurred in patients with end-stage renal failure following the development of vomiting, diarrhea and dysnatremia.^[Ref]

Dermatologic

Dermatologic side effects reported with PEG-ELS have rarely included urticaria and dermatitis.^[Ref]

Cardiovascular

Cardiovascular side effects of PEG-ELS have included arrhythmias and asystole.^[Ref]

The manufacturer notes an isolated case of asystole following ingestion of PEG-ELS in a geriatric patient (equal to or greater than 60 years of age).^[Ref]
