what is loratadine
If an allergy sufferer finds that their medicine isnât effective for them, they should consider trying a different active ingredient. Loratadine is an antihistamine used to treat allergies and relieve the symptoms of hay fever (allergy to pollen, dust, or other substances in the air) and other allergies. This ingredient works by blocking the action of histamine, which is a chemical naturally produced by the human body.
