"We may not be prescribing it widely enough," Dr. Brian Conway, medical director of the Vancouver Infectious Disease Center, told CTV News. According to him, this could be caused by a lack of awareness among both professionals and the public. "There hasn't been a lot of effort to make sure everyone knows what it is," he added.

Paxlovid is an antiviral in pill form that helps reduce severe forms of illness related to COVID-19. Prescribed at the start of the infection, patients must take two daily doses, of two pills, for five days.

In Canada, this drug is approved for people who are COVID-19 positive and who are at risk of developing health problems that may require hospitalization.

Although the provinces determine the eligibility criteria, Health Canada recommends that the drug be offered to people who are elderly, immunosuppressed or have serious underlying diseases, such as obesity or diabetes.

However, in Quebec, the list of criteria is more limited, the drug being reserved for people who are not adequately vaccinated or immunosuppressed. In people under the age of 60 who have not been adequately vaccinated, Paxlovid is reserved for those who have a serious underlying disease.

Each province has the authority to choose who can prescribe the drug, which can make the process simple or complicated depending on the policy in place, Dr. Conway believes. According to him, the simplest approach is to authorize the pharmacist to prescribe Paxlovid, as is the case in Quebec, Alberta, Saskatchewan and Newfoundland and Labrador.

Other provinces, such as Ontario and British Columbia, require the drug to be prescribed by a doctor or nurse practitioner. According to Dr. Conway, the fact that there are not enough professionals entitled to prescribe Paxlovid in the country is another cause of its underuse.

Earlier in July, the Canadian Pharmacists Association's chief pharmacist, Dr. Danielle Paes, called on provincial governments to allow pharmacists to prescribe treatments for COVID-19.

“Quebec was the first jurisdiction in the world to allow pharmacists to prescribe Paxlovid and has seen a marked increase in the use of the antiviral against COVID-19, helping to keep patients out of hospitals,” said , in a press release, Dr. Paes stating that other provinces have followed suit, but that many still do not offer this service.
