With a $63 billion merger nearing approval, AbbVie is counting on Allergan and its cash-cow Botox to boost sales—and that superstar could be a long-term winner. But not every drug in Allergan's stable is shining quite so brightly. 

Cosmetic and therapeutic Botox combined for $927.8 million in global sales in the third quarter, a 5.8% increase over the previous year, Allergan said Tuesday. Cosmetic sales in the U.S. grew the most, delivering $237.6 million––a 10% increase from the previous year. 

Botox's success has been a point of pride for AbbVie as it seeks to close its merger with Allergan in early 2020 and add some fresh air to the new company's offerings.
