Loratadine is a drug used to treat
allergies, and marketed for its nonsedating properties. It is marketed by
Schering-Plough under several trade names such as Claritin, Claritine, Clarityn or Clarityne depending on the market; by
Lek as Lomilan; by
Ranbaxy as Roletra; and by
Wyeth as Alavert. It is also available as a generic. In a version marketed as Claritin-D or Clarinase, loratadine is combined with
pseudoephedrine, a decongestant; this makes it somewhat useful for colds as well as allergies, but adds a potential side-effect of
insomnia, nervousness and anxiety.
