Warnings and precautions

Never stop or change an anti-epileptic on your own. Stopping abruptly can cause prolonged, dangerous seizures. Sodium valproate and divalproex must not be used by anyone who is pregnant or could become pregnant unless a specialist has confirmed there is no alternative — they cause serious birth defects and developmental problems.

Report yellowing of the eyes or skin, persistent vomiting, unusual bruising or severe tiredness at once. Tell your doctor about any change in mood or any thoughts of harming yourself. Take the same brand each time unless your neurologist has agreed to a change; switching can alter seizure control.

Several are not suitable in significant liver disease.
