How Does It Work?

Clemastine belongs to a class of drugs called antihistamines. Specifically, it is an H1 receptor antagonist. This means that it blocks a specific type of histamine receptor in the body (known as H1 receptors). Since allergic reactions are partly caused by the release of histamine from certain cells in the body, clemastine can help relieve or prevent allergy symptoms.
 
Clemastine also blocks acetylcholine receptors, an action which produces some of the unpleasant side effects of the medication (such as dry mouth or difficulty urinating) but also helps to relieve a runny nose.
