Pseudoephedrine/loratadine, sold under the brand name Claritin-D among others, is an orally administered combination medication used for the treatment of allergic rhinitis (hay fever) and the common cold.[1] Pseudoephedrine, one of the naturally occurring alkaloids of ephedra, is a sympathomimetic used as a decongestant.[medical citation needed] It produces a decongestant effect that is facilitated by the vasoconstriction in the mucosal capillaries of the upper respiratory areas.[medical citation needed] Loratadine is a long-acting antihistamine (H1 histamine antagonist) that is less sedating than older substances of its type.[medical citation needed]
In 2022, it was the 289th most commonly prescribed medication in the United States, with more than 500,000 prescriptions.[2][3]
