Fexona 120 120mg Tablet is an antihistamine used to treat allergies in adults and children. It alleviates allergy symptoms, like hay fever , by reducing histamine activity, a substance causing allergic reactions (such as watery eyes, runny nose, itching eyes/nose, sneezing, hives, and itching). Fexona 120 120mg Tablet is a non-drowsy antihistamine, meaning it’s less likely to cause sleepiness compared to other antihistamines.
