Synlor M Tablet belongs to the class of medications ‘antiallergic’ used in the treatment of allergic rhinitis. Allergic rhinitis (hay fever) is an allergic response to certain foods or pollen, pet dander, or other allergens.  Allergic condition varies from person to person. It is typically characterized by allergic symptoms such as a runny nose, sneezing, red, watery, itchy, and swollen eyes.

Synlor M Tablet is a combination of two medicines: Desloratadine and Montelukast. Desloratadine is an antihistamine and acts by blocking histamine's action (chemicals causing allergic symptoms) and reducing the allergic reaction. It provides quick relief from allergic symptoms. Montelukast is a leukotriene antagonist, which blocks a chemical messenger (leukotriene) and reduces inflammation and swelling in the nose.

You should take this medicine as prescribed by your doctor. The common side-effects of Synlor M Tablet are abdominal pain, headache, fatigue, and dry mouth.
