What is Desloratadine?
Desloratadine is an anti-allergy medicine. It contains the active ingredient desloratadine, which is a type of medicine called a non-sedating antihistamine. It works by preventing the actions of histamine. Desloratadine blocks histamine receptors to reduce sensitivity to certain stimuli. Desloratadine is called a non-sedating antihistamine as it doesn’t enter the brain and is therefore unlikely to cause drowsiness or sleepiness. Desloratadine is a prescription-only medicine.
What is Desloratadine used for?
Desloratadine is used to relieve the symptoms of nasal allergies such as hay fever, dust mite allergies or pet allergies, or to reduce hypersensitivity reactions to specific foods. The typical symptoms of these allergies include:
