When you have a runny nose and sneezing in the morning, you may have an infection or an allergic reaction. When an allergic reaction occurs, it is often caused by exposure to allergic substances in the air, and the eosinophils in the body may rise significantly. If you take anti-allergy medication, the effect is very obvious and the relief is very fast. In adults, loratadine, paracetamol, cetirizine hydrochloride can be used for treatment. In children, dexloratadine can be used for anti-allergic treatment. In case of infection, C-reactive protein tends to be significantly elevated. If the nose is clear, it indicates a viral cold and can be treated with cold medication, such as aminophenanthramine pellets or aminophen pseudomal dispersible tablets. If pus nasal discharge occurs, it indicates a bacterial cold and needs to be treated with antibiotics for better results, such as cefixime or cefaclor.
