Topiramate’s adverse effects are dominated by CNS-related and metabolic/sensory changes, with unique risks that guide safety concerns. The drug often causes cognitive dulling, slowed thinking, fatigue, and confusion due to its central nervous system activity. It also frequently leads to paresthesias and taste changes (dysgeusia), and it can reduce appetite with weight loss. Some patients experience flushing as well. A key safety aspect is the increased risk of nephrolithiasis (kidney stones) from carbonic anhydrase inhibition, and there is a known teratogenic risk, so it should be avoided in pregnancy. While nausea, dizziness, and rash can occur, they don’t capture the full, characteristic adverse-effect profile of topiramate, which centers on cognitive/psychomotor effects, sensory/weight changes, and stone/ pregnancy risks.
