Loratadina para alergias

About loratadine

Loratadine belongs to a group of medicines called antihistamines - it is an anti-allergy medicine. It stops the effects of a naturally occurring substance called histamine and this helps to relieve the symptoms of allergies such as hay fever and urticaria.

Exposure to substances such as pollen, pet fur, house dust or insect bites can cause your body to produce allergic symptoms. As células no revestimento do seu nariz e olhos liberam histamina quando entram em contato com essas substâncias. Isso leva à inflamação no nariz e nos olhos, o que produz sintomas como espirros e olhos lacrimejantes.

Urticaria is a condition where an itchy skin rash develops. The rash can be triggered by an allergy to a substance such as a soap or a detergent.

Loratadine can be prescribed for you by a doctor or dentist, or you can buy it without a prescription at pharmacies and other retail outlets. Tablet formulations are generally suitable for adults and older children, whereas oral liquid medicine is available for younger children. Loratadine is not suitable for children under 2 years of age.
