What Kind of Medicine Is Dexbrompheniramine?
Simply put, dexbrompheniramine is an antihistamine medicine. When you experience an allergy trigger, your body releases a natural chemical called histamine. This chemical is the main cause behind your sneezing, runny nose, and itchy eyes.
Dexbrompheniramine works by blocking the activity of histamine in your body. As a result, your allergy symptoms gradually fade away, giving you much-needed relief. It helps calm your immune system response so you can go about your day comfortably.
