Allerfast M Tablet belongs to a class of medication called 'anti-allergic' medication primarily used to treat allergic symptoms like sneezing, runny nose, congestion, stuffy nose or watery eyes. An allergy is a condition that occurs when the immune system reacts to a foreign substance that is typically not harmful to your body. These foreign substances are known as ‘allergens.’ Some might be allergic to certain foods and seasonal allergies like hay fever, pollen or pet dander. One of the main symptoms of allergy is cough, and it acts as a reflex action in the throat when there is any mucus or foreign irritant entry into the respiratory system.

Allerfast M Tablet is a combination of two drugs, namely Montelukast (leukotriene receptor antagonist) and Fexofenadine (antihistamine). Montelukast belongs to the class of leukotriene receptor antagonists that works by blocking the action of chemicals called leukotrienes that are released from the lungs causing inflammation (swelling) and increased mucus production in the airways. Thereby, reduces inflammation, mucus production and narrowing in the airways. Fexofenadine belongs to the class of antihistamines (anti-allergic drugs) that works by blocking the action of histamine, a substance responsible for causing allergic reactions.  It helps to provide relief from symptoms of allergy such as sneezing, running nose, watery eyes, itching, swelling, and congestion or stiffness.
