Why is there a weird taste in your mouth like you’ve been sucking on old pennies? In the medical community, this is referred to as dysgeusia (also called parageusia), which can develop suddenly or over a period of time. It is characterized by an unusual taste in the mouth that is typically metallic or rancid.
Dysgeusia can develop for a number of reasons. Most of the time, the cause is benign and the unpleasant taste will go away all on its own. In some cases, though, the metallic tang is a symptom of a more serious underlying disease or disorder that may require treatment, especially when it accompanies other symptoms.
Here are 13 possible reasons for that funky taste in your mouth…
You’re on Medication
Certain medications can cause dysgeusia. Some contain metals that are excreted through saliva. Others decrease saliva production or interfere with signals sent to the brain from the taste buds.
Drugs known to cause a metallic taste in the mouth include lithium (a psychiatric medication), allopurinol (for kidney stones and gout), and certain blood pressure medications and antibiotics.
