Canada Facing Nationwide Shortages of Opioid Pain Medication
/By Pat Anson
Pain patients in the United States have been dealing with persistent shortages of opioid pain medication for years. Now their counterparts in Canada face a similar issue.
Health Canada has issued a warning about nationwide shortages of oxycodone and acetaminophen combinations, along with medications that combine codeine with acetaminophen. Acetaminophen and oxycodone are sold under the brand names Percocet and Endocet, while acetaminophen-codeine combinations are often sold as Tylenol #3.
While the opioid shortages in the U.S. appear to be largely driven by a national opioid settlement that rations pain medication at the pharmacy level, the Canadian shortages are being blamed on manufacturing disruptions and increased demand.
“We recognize the importance of having acetaminophen with codeine or oxycodone products available for patients. Addressing this shortage is a top priority,” Health Canada said in a statement.
“We're communicating with health care providers, provincial and territorial governments, and distributors to coordinate the sharing of information about this shortage. We're also working with manufacturers and stakeholders to monitor the supply of acetaminophen with codeine or oxycodone and looking at options for increasing access to these products.”
The Canadian Pharmacists Association (CPA) expects the shortages to last a few more weeks, when a “significant resupply” is expected.
“The shortage is the result of manufacturing issues affecting one major supplier, which has increased pressure on other manufacturers. While the supply situation is expected to improve by mid-August, supply constraints are expected to continue until the end of September,” the CPA said in a statement.
A patient advocate says the opioid shortages don’t appear to be causing many problems for patients, at least not yet.
“As far as the shortages go, at least for those I was able to speak with, they are coping with it,” Barry Ulmer of the Chronic Pain Association of Canada told PNN.
“The real problem is the lack of actual doctors who will prescribe (opioids) and in doses needed. Even though Health Canada and the provincial regulators say opioids are O.K. to use, they still warn doctors about overprescribing and tapering is still a very real reality. Almost every doctor that I have known over the years have now retired or just plain quit because of this ongoing problem.”
Smaller Doses and Tapering Recommended
Until the shortages ease, the CPA is advising pharmacists to suggest non-opioid pain relievers for patients suffering from acute short-term pain, such as headaches and muscle strains.
For long-term pain patients already using oxycodone and codeine combinations, the CPA recommends limiting doses to 90 morphine milligram equivalents (MME) a day. Switching to another opioid and/or tapering is another alternative.
“If the current dose is high, give 50% or less of the new opioid converted to morphine equivalents. Otherwise, start with 60–75% of the previous dose converted to morphine equivalents,” the CPA said.
In the United States, either scenario would be considered a rapid taper, which can raise the risk of an overdose or mental health crisis. The CDC recommends more cautious tapering of patients, with a dose reduction of just 10% a month.
The American Society of Health-System Pharmacists (ASHP) first reported U.S. shortages of oxycodone-acetaminophen combinations in the summer of 2023. Not much has changed in the last two years.
In its June report, the ASHP said several drug manufacturers have oxycodone-acetaminophen combinations on back order, with no estimated resupply date. Only one drug maker, Major Pharmaceuticals, anticipates having new supplies in early August.
Some companies are phasing out the production of opioid medication. Endo Pharmaceutical stopped making Percocet in 2024, while Teva Pharmaceuticals discontinued production of immediate release oxycodone in 2023 and Transmucosal Immediate-Release Fentanyl Medicine (TIRF) in 2024. Opioid litigation has been very costly to Teva and other drug makers. In 2022, Teva paid $4.25 billion to settle thousands of opioid liability lawsuits.
