Is polyethylene glycol an antihistamine

No, polyethylene glycol (PEG) is not an antihistamine. It is a polymer used primarily as a laxative, in pharmaceuticals, and for various industrial applications. Antihistamines, on the other hand, are medications that block histamine receptors to alleviate allergy symptoms. While PEG may be used in formulations with antihistamines, it does not possess antihistamine properties itself.
