The subjective complaint of a metallic taste that can be from many different causes. These include medications such as zinc, metronidazole, and carbonic anhydrase inhibitor, such as acetazolamide. Other causes include peptic ulcer disease, glossodynia (i.e., burning mouth syndrome), and intoxication from various metals/compounds such as mercury or iodine or medications containing these elements.
There are other causes of metallic taste. Cymbalta is associated with causing an abnormal taste in some people. You may wish to discuss this with your prescribing physician and perhaps a switch in medication is indicated.
