Your symptoms suggest an allergic condition, possibly involving the airways and eyes. A slightly raised eosinophil count is commonly seen in allergies, asthma, allergic rhinitis, or sometimes parasitic infections. An allergic cough may be dry and triggered by dust, smoke, pollen, weather changes, or strong smells. Red eyes can occur due to allergic irritation or conjunctivitis. Medicines called antihistamines, such as cetirizine, levocetirizine, loratadine, or fexofenadine, are commonly used to reduce allergy symptoms, including cough, sneezing, itching, and eye redness. Lubricating or anti-allergy eye drops may also help soothe the eyes. If nasal allergy or wheezing is present, a doctor may advise inhalers or nasal sprays depending on the severity. It is important to avoid triggers such as dust, smoke, pets, and pollution as much as possible. Keeping rooms clean and using masks in dusty environments may help reduce symptoms. You should consult a doctor if the cough persists for more than a few weeks, or if you develop breathing difficulty, fever, chest pain, or worsening eye redness, as further tests or different treatment may be needed.
