It’s important to know the difference between seasonal allergies easily treatable with a simple OTC antihistamine and more serious symptoms that may require more attention. Seasonal allergies typically cause a runny nose, itchy or teary eyes, sneezing and sometimes itchy skin or a mild rash, and are caused by pollen or other airborne particles. If more serious symptoms like hives, difficulty breathing, a rapid heartbeat or feeling faint appear suddenly it may be the result of a more serious allergic reaction and immediate medical attention should be sought. Your local pharmacy is always happy to provide you with the medication suitable for your symptoms if appropriate!
