Story 40 Epival (divalproex) for bipolar disease

A psychiatrist in SW Ontario writes:

Yesterday, I had a long conversation with a local pharmacy and they are out of Epival, generic, until Feb 26 at the earliest.  They ordered in 125 mg tabs of the parent drug for my patient.  Nobody has 250 mg tabs and for many people, they will be unavailable.  Epival is one of the drugs used with Bipolar patients and is used extensively in Psychiatry for other problems.  I am haunted by the thought of a number of previously stable people becoming ill through this problem.
