Yes, both medications contain the exact same active ingredients: sodium valproate and valproic acid in a controlled-release formula. However, different brands can use different inactive ingredients or manufacturing processes. This can slightly alter how your body absorbs the medication, which may cause temporary side effects like nausea and dizziness after a switch. Please do not stop or change your dosage on your own, as keeping a consistent level of medication is crucial for seizure control. I highly recommend discussing these symptoms with your doctor; they can help you manage these side effects or safely adjust your treatment.
