Medicamentos para alergia

Uma reação alérgica happens when your immune system over-reacts to a foreign particle or chemical that is usually harmless. Allergic reactions range from mild symptoms of sneezing or itching to severe symptoms of anafilaxia, affecting your breathing and circulation. People at risk of anaphylaxis should carry an auto-injetor de adrenalina at all times. Most allergies can be treated or prevented with antihistamines such as loratadina ou clorfenamina. Other useful treatments include colírio de cromoglicato de sódio and steroid nasal sprays such as beclometasona ou fluticasona.
