Last month, the jury awarded Barton $3.75 million in compensatory damages and found Wyeth willfully hid evidence of a cancer link.
The punitive award for Barton, of Peoria, Ill., had been sealed until Monday because of another Prempro case under way in the same courthouse.
A spokesman for Pfizer Inc., which recently acquired Wyeth, says the company will challenge the Barton verdict, and another verdict also announced Monday.
Barton's case is one of a handful of Prempro lawsuits to go to trial out of several thousand filed across the country.
