What Causes a Metallic Taste When I Cough?

When people experience a metallic taste when they cough, it can be disconcerting and cause them to worry. However, the sensation is usually temporary and can be relieved with a variety of treatment options.

Tasting blood when you cough is a medical condition called hemoptysis. It occurs when the irritation and inflammation in the respiratory system causes small amounts of blood to leak into the lungs, causing a sour or metallic flavor in the mucus that is coughed up. This is a common symptom of bronchitis, pneumonia, lung cancer, or tuberculosis.

Metalic tastes associated with a cough can also be caused by certain medications and underlying health conditions. If you are taking any medication that induces a metallic taste as a side effect, consult your healthcare provider to ensure proper dosage and alternatives.

Acid reflux (GERD) can cause a metallic taste when you cough because it damages the lining of your throat. Managing your diet, making lifestyle changes, and taking prescribed medications can help manage this condition and alleviate the accompanying symptoms.

Using an oral rinse formulated to combat the metallic taste during coughing, such as MetaQil, can provide relief from this uncomfortable symptom. The rinse can be swished around the mouth for the recommended period of time and then spit out, to relieve the metallic taste during coughing episodes.

The underlying health conditions that can trigger the metallic taste when you cough include allergies, asthma, and acid reflux. Managing these conditions by following your treatment plan, taking appropriate medications, and avoiding trigger foods can help reduce the frequency of the metallic taste sensation and its severity.
