I developed alexia due to a brain clot and previously had seizures, which are now controlled. I currently take Phenytoin 100 mg and Levetiracetam 1000 mg. For the past 2-3 days, I have been experiencing ataxia. Could this be a side effect of my medications, and should my treatment be adjusted?

Have a query?

Yes, your recent ataxia (unsteadiness or poor balance) can be related to your medicines, especially Phenytoin, which is well known to cause imbalance, coordination problems, and dizziness, particularly if the blood level becomes high. Levetiracetam is less likely to cause ataxia but can contribute to dizziness in some people. Since your seizures are controlled, this side effect is important to address, and you should see your doctor soon to check phenytoin blood levels and review your doses, as adjustment or switching medicines may be needed. Do not stop the medicines suddenly, but avoid activities like driving until you are steady, and seek urgent care if the imbalance worsens, or if you develop slurred speech, severe drowsiness, or vision problems.
