nirmatrelvir / ritonavir (Paxlovid)

Paxlovid is recommended for adults over 18 if they:

  • have developed symptoms that began in the last 5 days, and
  • have tested positive for COVID-19, and
  • are at higher risk of severe outcomes.

Patients may be considered at higher risk of severe outcomes if they:

  • are not fully vaccinated,
  • are an older adult – your risk increases with age,
  • have one or more chronic medical conditions,
  • are moderate to severely immunocompromised, due to a medical condition or treatment.

Pharmacists may refuse to fill a prescription for Paxlovid from another prescriber due to a drug interaction, medical condition or if the patient is determined to be ineligible for Paxlovid. Pharmacists are eligible to claim a refusal to fill fee using the PIN listed in the Claim Submission section.
