For Healthcare Professionals
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]
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]
Cardiac arrhythmias, especially increased ventricular ectopy, have been associated with PEG-ELS use.
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]
Cardiovascular side effects of PEG-ELS have included arrhythmias and asystole.[Ref]
A 70-year-old male developed shortness of breath, wheezing, skin flushing, and lowered blood pressure after drinking a second glass of PEG-ELS.[Ref]
Other side effects with PEG-ELS have included rhinorrhea.[Ref]
The manufacturer notes isolated reports of 'butterfly-like' infiltrate on chest X-ray following vomiting and aspiration of PEG-ELS and sudden dyspnea with pulmonary edema in geriatric patients (equal to or greater than 60-years-old).[Ref]
Tonic-clonic seizures have been reported in patients with and without previous history of seizures following administration of PEG-ELS (4 liters).[Ref]
