Safety considerations for nirmatrelvir/ritonavir (Paxlovid¨) use in persons living with HIV whether or not on antiretroviral treatment, or persons at risk of HIV while on PrEP who are diagnosed with COVID-19 infection

The COVID-19 therapy Paxlovid¨ consists of the antiviral medication nirmatrelvir co-packaged with the pharmacokinetic enhancer (“booster”) ritonavir, taken as a twice daily, oral, five-day treatment course, with dosage adjustment required for renal impairment (see prescribing information).

Nirmatrelvir/ritonavir treatment is initiated as soon as possible following a positive SARS-CoV-2 test result. Eligibility criteria for nirmatrelvir/ritonavir vary between Canadian provinces and will likely evolve over time. Also, eligibility in British Columbia may be expanded as drug supply increases. Therefore, prescribers are strongly encouraged to refer to current nirmatrelvir/ritonavir prescribing information and local guidelines for treatment eligibility and general contraindications/precautions. In British Columbia, see the BC Centre for Disease Control website: http://www.bccdc.ca/health-professionals/clinical-resources/covid-19-care/clinical-care/treatments

During the Canada Post strike announced September 25, 2025, the following measures will be undertaken to minimize service disruption to BC-CfE clients and providers.

  • The BC-CfE Laboratory has transitioned to private courier for delivery of outgoing reports and documents. Results required urgently can be faxed upon request. (Lab Contact Information: Phone 604-806-8775; FAX 604-806-9463)
  • The BC-CfE Drug Treatment Program (DTP) will fax outgoing forms and documents to the provider’s office. (DTP Contact Information: Phone 604-806-8515; FAX 604-806-9044)
  • St. Paul’s Hospital Ambulatory Pharmacy has transitioned to private courier for delivery of medications. We recommend requesting medication at least 2 weeks in advance in case of delivery delays, particularly to rural/remote parts of BC. (Contact Information: Phone 1-800-547-3622; FAX 604-806-8675)

During the Canada Post strike, we recommend that documents be faxed or couriered to our sites, versus utilization of regular mail service

The BC-CfE Laboratory is streamlining reporting processes for certain tests in order to simplify distribution and record-keeping, and to ensure completeness of results. Beginning September 2, 2025, results for the ‘Resistance Analysis of HIV-1 Protease and Reverse Transcriptase’ (Protease-RT) and ‘HIV-1 Integrase Resistance Genotype’ tests will be combined into a single ‘HIV-1 Resistance Genotype Report’.
