You may be required to take a COVID-19 test during your appointment to determine eligibility.

For more information on whether you possibly qualify read this fact sheet.

To be considered for treatment, you must have tested positive for COVID-19 (by polymerase chain reaction (PCR) or rapid antigen test), and a health care provider must assess you to determine if treatment is right for you, which includes whether or not you are at higher risk of developing severe symptoms.

You may be at higher risk if you are:

  • over 18 years old and immunocompromised (have an immune system that is weakened by a health condition or medications)
  • over 70 years old
  • over 60 years old with fewer than three vaccine doses
  • over 18 years old with fewer than three vaccine doses and at least one of the following risk conditions:
    • obesity
    • diabetes

    • chronic respiratory disease (including cystic fibrosis)
    • cerebral palsy
    • intellectual or developmental disabilities
    • sickle cell disease
    • moderate or severe kidney disease
    • moderate or severe liver disease
    • pregnant and unvaccinated (zero doses)

Patients who may be at higher risk should contact a health care professional to be assessed as soon as possible. These patients should either:

  • contact their primary care provider;
  • call Telehealth Ontario at 1-866-797-0000; or
  • visit a COVID-19 clinical assessment centre

Treatment with Paxlovid must begin within five days of symptom onset to be effective. A full course of treatment is three pills twice daily for five days in a row.

Paxlovid is not a replacement for vaccination. This antiviral is a treatment that is intended for those who are at a higher risk of severe outcomes that may lead to hospitalization.

Before you are approved for Antiviral treatment:

  • An appropriate health care provider, often a pharmacist, will determine if you qualify.
  • If you are deemed to qualify for oral Antiviral treatment with Paxlovid. A health care provider and pharmacist will review your current medications and determine if any changes to your other medications are necessary to safely take Paxlovid.
  • You may require additional lab work to review liver and kidney function prior to being approved for treatment.
