Common Allergies and Medications

A summary of common medication for treating allergies grouped by their purpose:

Active ingredient: Guaifenesin (400-600 mg)
Thins and loosens mucus, making it easier to be coughed out. [1]

(Nasal) Decongestant
Active ingredient: Phenylephrine (10 mg), Pseudoephedrine (part of Decondine)
Relieves nasal congestion in the upper respiratory tract by constricting blood vessels and reducing the blood supply to nasal mucous membranes. This reduces nasal congestion, stuffiness, and runny noses. [1]

Active ingredient: Loratadine (10 mg), Triprolidine (part of Decondine)
Reduce or block histamines. Histamine is an organic compound produced by local immune responses. It results in running nose and sneezing. [1] [2] [3]

Active ingredient: Dextromethorphan (20 mg)
Used for temporarily cough relief; suppresses cough reflex. [1]

Pain Reliever
Active ingredient: Acetaminophen (650 mg)
Main purpose is to treat headaches and minor body pain. Also reduces fever.

The physiological mechanism of allergic reactions is the same, however, in everyone. Allergens enter the body -- either through ingestion, inhalation or contact with the skin or mucous membranes. This causes white blood cells to release an antibody which then binds to what are known as mast cells. The mast cells rupture – and in the process, release biochemical substances including histamine.
