How This Drug Works
Antihistamines, H1
Histamine antagonists or antihistamines are drugs that relieve allergy symptoms. Histamine is a chemical used to identify and remove substances that trigger an allergic response.
Histamine antagonists or antihistamines are drugs that relieve allergy symptoms.<br><br>Histamine is a chemical used to identify and remove substances that trigger an allergic response.  There are four histamine receptors &#40;designated H<sub>1</sub>, H<sub>2</sub>, H<sub>3</sub>, H<sub>4</sub>&#41;. When histamine activates H<sub>1</sub> receptors, symptoms such as rashes, itching, watery eyes and trouble breathing may begin. <br><br>Antihistamines prevent histamine from stimulating the H<sub>1</sub> receptors located in the eyes, nose and throat to relieve swelling and stop leaking fluid.  First generation antihistamines were non-selective for H<sub>1</sub> receptors and crossed into the brain resulting in drowsiness.  Newer antihistamines are more selective, reducing this side effect.

Only drug effective for my hay fever
For me this drug simply outperforms any other drug on the market. It controls my hay fever without drowsiness or dry mouth that is so common with other drugs.
