Haylief Loratadine Tablets can relieve allergic symptoms due to hayfever and other airborne allergies such as house dust mite and pet allergies. Loratadine Tablets may also be taken for allergic skin conditions including rash, itching and urticaria (hives). One tablet starts to work within minutes and delivers a full 24 hours relief - MHRA guidelines do not allow the use of the words 'Non-Drowsy' but Loratadine remains a Non-sedating anti-histamine.
