Divalgress-ER 250 Tablet (divalproex sodium extended release 250 mg) is prescribed for conditions such as epilepsy, bipolar disorder, and migraine prevention. The duration of use depends on the condition being treated, your response to therapy, and your doctor’s assessment. In some cases, it may be required for a few months, while in others, such as epilepsy or bipolar disorder, it may need to be continued long-term. Always follow your doctor’s instructions, and do not stop or change the dose on your own, as sudden discontinuation can worsen symptoms or trigger relapse.
