How does loratadine work in the body? How long does loratadine last?

Loratadine is an antihistamine.  Antihistamines work to control allergy symptoms by blocking histamine receptors in the body.  Histamine is released by the body as part of allergic reactions. Since the histamine released by the body cannot reach the receptors, symptoms do not occur or are less severe.loratadine-how-long-does-it-last-how-does-it-work

Loratadine starts to work within 1 to 3 hours after taking.  The effect of the medicine peaks at about 8 to 12 hours, the duration of the the effect is 24 hours or longer. That means one dose should provide relief for 24 hours.
