Although each medication has its own side effect profile, there are some common features for anti-seizure medications. These medicines may cause tiredness, dizziness, or balance problems. Some are also associated with changes to mood or thought processing. However, the vast majority of side effects are mild and short-lived, so if you continue taking the medication, your body will adjust. Always reach out to your care team for any concerning side effects, particularly if you're experiencing severe mood changes as a change might be needed. The goal of care at NCES is to prevent seizure activity while maintaining quality of life!
