ABSTRACT The evacuant solution (ES) is a drug that has been used to clean the colon. The most common described side effects when using this drug are abdominal symptoms; skin rash is rare. We report on two patients who presented urticaria and angioedem after the intake of an evacuant solution to make a rectoscopy. We performed allergy studies: skin prick tests with common inhalants, pure ES and the components (polyethylene glycol 4000 (PEG 4000), KCI, NaCO3, NaPO3, NaSO3, NaCI, neohesperydine…

Allergy to PEG should be considered in painters who develop urticarial or other systemic symptoms after handling PEG-containing products, including male painter who visited an outpatient clinic after developing a distinct skin reaction 15 min after the ingestion of a laxative solution containing polyethylene glycol prior to colonoscopy.

Contact Urticaria with Systemic Symptoms due to Hexylene Glycol in a Topical Corticosteroid: Case Report and Review of Hypersensitivity to Glycols

We report a case of severe contact urticaria with systemic involvement resembling an anaphylactic reaction, following the application of a topical corticosteroid. This was caused by hexylene glycol,

This first comprehensive review provides practical information for allergists and other healthcare professionals by describing the clinical picture of 37 reported cases of P EG hypersensitivity since 1977, summarizing instances where PEG hypersensitivity should be considered and proposing an algorithm for diagnostic management.

The safety of osmotically acting cathartics in colonic cleansing

The available evidence indicates that PEG–ELS-based products are the safest option, but these products should be administered with caution to elderly individuals and patients who are prone to develop disturbances in water and electrolyte balance.
