What is it indicated for?

Bentrio is intended to treat hay fever and allergy sufferers by promoting alleviation of mild allergic symptoms (i.e., mild nasal irritation including itchy, runny, or congested nasal passages) triggered by the inhalation of various airborne allergens including indoor and outdoor environmental pollens, house dust, animal hair and dust mites.

Application of Bentrio produces a mucous-like gel barrier that coats the nasal membranes, traps inhaled allergens within the nasal cavity and helps with their clearance.

Indications for use as stated in the FDA summary.
