Metallic smell may be due to medication, anxiety

DEAR DR. GOTT: I am a 54-year-old female in fairly good health. The only medications I take are Buspar and Dexilant.
I would like to know if you could tell me why I smell metal all the time. My husband and son don’t, but I do. Do I need to have blood work done to find the cause? Thank you for your response.

DEAR READER: One of your medications may cause this smell. The Dexilant is commonly used for erosive esophagitis caused by acid reflux. Reflux can cause bad breath and a metallic taste (and possibly scent). The medication itself can also cause breath odor.
