Qudexy is FDA-approved for partial-onset seizures and primary generalized tonic-clonic seizures in adults and children, as well as for migraine headache prevention in adults. It may also be used as part of combination therapy for other conditions as determined by a healthcare provider.
As a seizure medication, Qudexy works through multiple mechanisms in the brain, including blocking sodium channels, enhancing GABA activity, and inhibiting carbonic anhydrase. These actions help reduce abnormal electrical activity that causes seizures and migraines.
Qudexy may cause drowsiness, dizziness, or vision changes; avoid alcohol during treatment. It can increase the risk of birth defects if taken during pregnancy. Do not stop taking Qudexy abruptly without medical supervision, as this may increase seizure frequency. Adequate hydration is important, especially in warm weather, to reduce the risk of kidney stones.
