Which medication category is associated with changes in taste and smell and other effects including tinnitus?

• A. Antibiotics
• B. Antiseizure drugs
• C. Antihistamines
• D. Diuretics

Answer: (B)

Sensory changes such as altered taste and smell, along with tinnitus, are documented adverse effects of many antiseizure medications. For example, topiramate is well known for causing dysgeusia—a metallic or distorted taste—which can affect appetite and nutrition. Tinnitus can also appear with some anticonvulsants as part of broader central nervous system or ototoxic-type effects, especially when used long term or with other meds. Because taste and smell changes can influence intake and overall well-being, recognizing this pattern helps in monitoring patient response, assessing for dose-related effects, and guiding counseling or adjustments. While other drug classes can occasionally cause taste or ear-related symptoms, the combination described is most consistently associated with antiseizure medications.
