Taste alteration (dysgeusia) is associated with over 200 drugs and can have a major impact on quality of life. This side effect is often overlooked by clinicians.
Most common offending classes of medications are antibiotics, antifungals and antivirals, cardiac medications, chemotherapy agents, Parkinsonian and migraine agents, thyroid medications, and psychotropics.
