Shares of Mylan held slightly lower in afternoon trade Thursday, giving up earlier gains of more than 4 percent.

The stock climbed in morning trade after the firm announced expansion of existing cost-cutting programs for its EpiPen, a life-saving device for people with severe allergies.

In late-morning trade, Democratic presidential candidate Hillary Clinton's spokesman told MSNBC that Mylan's EpiPen discounts are "insufficient."
