###Human: How can eosinophilia be treated ? ###Assistant: Hi. High eosinophils are found in conditions with allergic reactions. I would recommend you to please see your doctor and if your chest is congested, they would help you with antibiotics, short steroids, anti-allergic, and nebulizer. If you are asymptomatic with just mild cough, a short course of two weeks with antiallergics like a combination of Levocetirizine and Montelukast works wonders.
