The US Food and Drug Administration has recommended tighter controls on prescriptions for painkillers such as Vicodin and Lortab that contain the powerful narcotic hydrocodone.
The change will cut in half the number of refills that patients can get before seeing their doctor to get a new prescription, the agency said.
Patients also will have to take a prescription to their pharmacy to have it filled, rather than have a doctor call it in.
The FDA announced that it will also ask in mid-December that all prescription medications containing hydrocodone be reclassified as "Schedule II" medications.
As Schedule II drugs, these painkillers will be subject to the same type of strict control as other narcotics with the highest potential for abuse, including OxyContin, methadone, fentanyl, Adderall and Ritalin.
The FDA has been spurred to action by epidemic levels of prescription drug abuse in the United States, said Dr Janet Woodcock, director of the agency's Centre for Drug Evaluation and Research.
The agency struggled over the impact that the change might have on patients, she said, but decided that public health concerns have become paramount.
"These are very difficult tradeoffs that our society has to make," Woodcock told The New York Times. "The reason we approve these drugs is for people in pain. But we can't ignore the epidemic on the other side."
One out of every five Americans has used prescription drugs for non-medical purposes at some time, according to the US National Institutes of Health. Some 22 million Americans have misused prescription painkillers since 2002.
About 131 million prescriptions for medications containing hydrocodone were issued to an estimated 47 million patients in 2011. According to government estimates, that's equivalent to about 5 billion pills, the Times reported.
Dr Lynn Webster, president of the American Academy of Pain Medicine, said: "This decision will mean there will be far less hydrocodone prescribed, and far less of it diverted [for abuse]. There will be an increase in health care costs due to more frequent office visits and co-pays, but it will take a bite out of the prescription drug crisis. We can't have status quo. We can't be doing what we have been doing for the last two decades."
The new regulations could take effect as early as next year, Woodcock said. The U.S. Department of Health and Human Services must approve the recommendation before it can be adopted by the U.S. Drug Enforcement Administration, which has been pushing for tougher regulation of hydrocodone medications.
Patients currently can refill a prescription for a drug containing hydrocodone five times during a six-month period before having to return to their doctor for a new prescription.
The new regulations would cut that period down to three months before a new prescription is required.
"There's no question that these are important changes in the right direction," said Dr. G. Caleb Alexander, co-director of the Centre for Drug Safety and Effectiveness at Johns Hopkins School of Public Health in Baltimore. "The FDA plays a critical role in helping to reduce the toll that this epidemic has taken. The clinical community and public health community will welcome these changes."
However, Alexander said doctors and regulators need to keep an eye on problems for patients that result from the tighter control.
"The bottom line is these kind of complex policies are often hard to predict," he said. "They can have both intended or unintended consequences."
Earlier this year, an FDA advisory panel voted 19 to 10 in favour of reclassifying hydrocodone-based painkillers as Schedule II drugs.
