Regulators are changing the look of prescription drug labels.

Rules outlining a new format will be issued soon, said Dr. Scott Gottlieb, the Food and Drug Administration deputy commissioner for medical and scientific affairs.

"This is an important step toward creating an electronic environment for drug safety and drug effectiveness information that will make it easier for doctors and patients to get up-to-date information right at the point of care," Gottlieb told reporters.

Drug makers will have to submit changes to their product labels electronically starting next month in a standard format that makes updating older versions "seamless and automatic," Gottlieb said.
