What is Chlorphenamine used to treat?

This medicine contains the active ingredient chlorphenamine maleate, which works by inhibiting the action of histamine in your body.
Histamine is a natural chemical in the body which is a natural defence system against foreign bodies. In most instances, histamine is beneficial to the body, but when you come into contact with an allergy trigger it can cause unpleasant symptoms. This is the cause of hay fever and other allergic reactions.
