Was taking Depakote ER 500mg 2X day for three months for seizures. Begining of fourth month noticed significant hair loss. Fifth month medication was been changed to topamax. Hair loss has slowed but not stopped yet with no sign of regrowth. At this poit have lost about 20-25% of hair on top of my head and texture is very limp. Has anyone been through this? My doctor thinks it will come back, but he does not seem to have any information beyond that.
