Question: what is the difference between divalproex extended release and delayed release?
Answer: The “ER” in Depakote ER stands for Extended Release. Available in two strengths, Depakote ER contains the same active ingredient as Depakote Delayed-Release Tablets but it is designed to slowly deliver the medication over a 24-hour period. This means that Depakote ER only has to be taken once a day.
