Piriton great for hayfever

Piriton is the trade name of the allergy medication called Chlorphenamine. It used to be called Chlorpheniramine.

It belongs to a group of chemical compounds called alkylamine. This brand of chlorphenamine is manufactured and supplied by GlaxoSmithKline (GSK) Consumer Healthcare Limited.

It is a potent anti-histamine medication.

Anti histamines are medications that help in blocking the actions of a chemical (histamine) produced by special cells in the body called mast cells.

When mast cells release histamines and other group of chemicals, these lead to the development of rashes, swellings, wheezing and other symptoms seen in allergic reactions. When antihistamines are taken, they help stop or minimize such reactions.

Piriton is such a good allergy medication that it is often the first drug of choice prescribed for the relief of symptoms of many allergic diseases.

It is commonly used in following conditions:

  • Hay Fever (allergic rhinitis)
  • Hives and Nettles (Urticaria rash)
  • Insect bite, wasp or bee sting in combination with appropriate antibiotics if indicated
  • Itchy skin conditions in general
