Singulair May Help Reduce Tonsil and Adenoid Enlargement

Singulair is a medication often prescribed for asthma as well as allergies and works by blocking the leukotriene receptor. This mechanism is different than that found in common allergy medications like claritin and benadryl which work by blocking the histamine receptor (anti-histamine).

Singulair has also incidentally been found to possibly help reduce the size of tonsils and adenoids. Given this beneficial affect, singulair may be a helpful intervention in those kids with mild obstructive sleep apnea or nasal obstruction due to adenoid hypertrophy avoid surgical intervention (tonsillectomy and adenoidectomy).

Steroid nasal sprays have also been found helpful to reduce adenoid size.

However, only an association between singulair use and reduction in adenoid/tonsil size has been found. Double-blind, placebo-controlled studies are required for determination of true benefit.

Singulair can be given from the age of 1 year old.
