What are the uses of Loratadine?
Generally, antihistamines are used to treat symptoms of allergies. It works by blocking the action of histamines which are released by the body’s immune system in response to an infection. Usually, histamines help protect our body from infections, but sometimes histamine can be released when the immune system mistakenly fights off harmless substances (allergens) such as dust and pollen.
The general uses of Loratadine comprise of :
- Allergic rhinitis (nose inflammation due to allergens such as pollen)
- Allergic skin reactions such as urticaria or eczema
- Allergic conjunctivitis (eye inflammation)
- Allergic fever, also known as hay fever
However, Loratadine cannot be used to treat severe allergic reactions (anaphylaxis). Anaphylaxis requires immediate medical intervention.
