Yes, your vertigo can be related to your medications; drugs like Phenytoin and Sodium Valproate are known to cause dizziness, imbalance, or a spinning sensation in some people, and these symptoms may take a few days to a few weeks to settle after stopping or changing the medicine. Cinnarizine can help control vertigo and is generally safe for short-term use (a few weeks), but long-term use should only be under a doctor's supervision because it can cause side effects like drowsiness or, rarely, movement problems. Since your MRI and tests are normal and your seizure was triggered by hypoglycemia, the vertigo is more likely medication-related, but other causes like inner ear problems, low blood pressure, or anxiety can also contribute, so if the dizziness persists, worsens, or affects walking or vision, you should follow up with your doctor to review your medications, check drug levels if needed, and rule out other causes.
