Amid an uproar over the steep increase in the cost of the EpiPen, a lifesaving injection device for people with severe allergies, Hillary Clinton announced a plan on Friday to crack down on unwarranted rises in price for prescription drugs that have long been available.

As part of the plan, Mrs. Clinton would create a team of federal officials that would seek to protect consumers by monitoring price increases. The plan also lays out several actions that the government would be able to make in response to “excessive” rises in price, including taking steps to expand access to treatments and imposing penalties on drug companies, such as fines.

“Over the past year, we’ve seen far too many examples of drug companies raising prices excessively for longstanding, lifesaving treatments with little or no new innovation or R. & D.,” Mrs. Clinton said in a statement. “It’s time to move beyond talking about these price hikes and start acting to address them.”

The price of EpiPens has risen to about $600 for a pack of two, from about $100 in 2007, when the pharmaceutical company Mylan acquired the product.
