Claritin is a Brand name of Loratadine which was developed by Schering-Plough in 1981 and marketed not until 1993, when it was listed among the World Health Organization’s List of Essential Medicines.  It is basically used to fight Histamines “chemical” released into your body system as part of an allergic reaction. Such allergies includes:-

  • allergic rhinitis (hay fever)
  • pollen
  • sneezing
  • watery eyes
