Health Canada reminded the pharmaceutical industry Friday about export rules designed to prevent drug shortages after a major shift in U.S. policy on buying prescription medication from north of the border sparked fears of a supply crunch.

The U.S. Food and Drug Administration announced plans Friday to allow Florida to import millions of dollars worth of pharmaceuticals from Canadian wholesalers as a way to avoid the high cost of drugs in that country.

The decision is not great news for Canada, which has more frequently faced acute drug shortages over the last several years, said Joelle Walker, vice-president of public affairs for the Canadian Pharmacists Association.

The population of Florida is more than half the number of people who live in all of Canada. And beyond Florida, other American states are eyeing similar requests to the FDA to address the cost of drugs.

鈥淭o look to Canada as their pharmacy is just not practical. We can鈥檛 do it, it鈥檚 not possible,鈥� Walker said.

An association of Canadian pharmaceutical companies called Innovative Medicines Canada also expressed serious concerns about what would happen if the U.S. starting buying up Canadian medicines.

鈥淐anada simply can鈥檛 supply drugs to Florida, or any other U.S. states, without significantly increasing the risk and severity of drug shortages nationwide,鈥� said David Renwick, the association鈥檚 interim president.

鈥淭he U.S. market is nearly 10 times bigger than Canada鈥檚, and allowing drugs that were intended for Canadians to be exported to the U.S. would harm Canadian patients and disrupt our health-care system.鈥�

Over the last several years Canada has run short on a range of drugs, from children鈥檚 fever medication, to certain cancer drugs and, more recently, the popular weight-loss and diabetes management drug Ozempic.

Florida鈥檚 proposal includes medications for asthma, chronic obstructive pulmonary disease, diabetes, HIV and AIDS and mental illness.

But the threat is not immediate, Walker said, and people should not rush to refill their prescriptions.

Florida still has more work to do to prove imports would actually save Americans money without sacrificing public safety, as well as test the drugs to make sure they鈥檙e authentic and relabel them so that they comply with U.S. standards.

鈥淭hat in itself could actually be quite cost prohibitive and we hope will be a disincentive for Florida from proceeding,鈥� Walker said.

If a manufacturer wants to export drugs to the U.S., it would need Health Canada鈥檚 approval, which the federal regulator would presumably deny if it feared a shortage.

Health Canada sent a bulletin on Friday that suggests it intends to hold that line.

The message reminded pharmaceutical manufacturers and distributors, as well as pharmacists and others in the sector about existing safeguards against shortages.

Canadian regulations ban the distribution of certain domestically produced pharmaceuticals outside the country if there are 鈥渞easonable grounds to believe that doing so could cause or worsen a drug shortage,鈥� the bulletin said.

鈥淒rugs intended for the Canadian market can continue to be sold for consumption outside of Canada if the sale will not cause or exacerbate a drug shortage in Canada.鈥�

The U.S. pays by far the highest price for patented medicines among members of the Organization for Economic Co-operation and Development, with essentially no government limits on what companies can charge. While Canada pays far less by comparison, its prices still ranked third highest as of 2021.

Americans have long been able to fill prescriptions from Canadian pharmacies, but the newly announced policy change affects mass imports.

The FDA鈥檚 decision follows years of successful lobbying against the idea by the pharmaceutical industry, which said imports would expose U.S. patients to risks of counterfeit or adulterated drugs. The FDA also previously warned of the difficulties of assuring the safety of drugs originating from outside the U.S.

The politics surrounding the issue have shifted in recent years, with both Democrats and Republicans doubling down on the import approach.

The medications would be only for certain people, including foster children, inmates, certain geriatric patients and 鈥� eventually 鈥� Medicaid recipients.
