This information is designed to support medical practitioners, including General Practitioners, to prescribe COVID-19 treatments and to refer patients for consideration of medicines supply from the National Medical Stockpile for the early intervention of COVID-19.

COVID-19 treatments

There are currently five therapies, available from the National Medical Stockpile, provisionally registered by the Therapeutics Goods Administration (TGA) for the treatment of mild COVID-19:

  • nirmatrelvir plus ritonavir (Paxlovid®)
  • molnupiravir (Lagevrio®)
  • remdesivir (Veklury®)
  • sotrovimab (Xevudy®)
  • casirivimab plus imdevimab (Ronapreve®)

Supplies from the National Medical Stockpile can vary according to outbreaks and demand. In the setting of limited supply certain risk factors or patients with greater than one risk factor may be prioritised for treatment.

The Commonwealth Government has provided a supply of National Medical Stockpile medicines directly to Residential Aged Care Facilities.

COVID-19 Pre-Exposure Prophylaxis (PrEP): tixagevimab-cilgavimab (Evusheld®)

A limited supply of tixagevimab and cilgavimab (Evusheld®) from the National Medical Stockpile (NMS) is available in South Australia for use in high-risk people for pre-exposure prophylaxis (PrEP) of COVID-19.

Tixagevimab and cilgavimab (Evusheld®) is currently available to Tier 1 and Tier 2 priority patients; refer to the Clinical Guideline and/or Eligibility Declaration Form for complete eligibility criteria.

Evusheld® is available for eligible patients through public hospitals and some private hospitals - contact the relevant specialist or the site’s pharmacy department for further information.

Referrals for eligible patients for Evusheld® administration can also be made to a small number of Priority Care Centres (PCCs).

To refer eligible patients for pre-exposure prophylaxis tixagevimab and cilgavimab (Evusheld®) at a Priority Care Centre, please submit a completed Eligibility Declaration Form through the  Evusheld® Treatment Referral Portal.

Antiviral treatments

Nirmatrelvir plus ritonavir (Paxlovid®) and molnupiravir (Lagevrio®)

Nirmatrelvir plus ritonavir (Paxlovid®) and molnupiravir (Lagevrio ®) are oral antiviral medications which reduce SARS-CoV-2 replication. When commenced within five days of symptom onset, in patients at high risk of progressing to severe illness, nirmatrelvir plus ritonavir and molnupiravir have been shown to reduce hospitalisations and death from COVID-19 by approximately 88% and 30% respectively.

Paxlovid® and Lagevrio® are both listed on the Pharmaceutical Benefits Scheme (PBS) for the following groups of patients with COVID-19 not requiring supplemental oxygen:

  • People 50 years of age or older, with two additional risk factors for developing severe disease;
  • People 30 years of age or older, identifying as Aboriginal or Torres Strait Islander, with two additional risk factors for developing severe disease; and
  • People 18 years of age or older, with moderate to severe immunocompromise;
    where treatment is commenced within 5 days of the onset of signs/symptoms.
  • People 70 years of age or older, where treatment is commenced within 5 days of the onset of symptoms, or where asymptomatic, treatment is initiated as soon as possible after diagnosis is confirmed.

Further PBS information

Remdesivir

Remdesivir is an intravenous antiviral which inhibits SARS-CoV-2 replication. When given within seven days of symptom onset remdesivir decreased hospitalisation in outpatients with mild COVID-19 by 72%. Three intravenous doses of remdesivir on consecutive days is recommended.

Guidelines for outpatient COVID-19 treatment

The following COVID-19 Mild Illness treatment guidelines have been developed by the Central Adelaide Local Health Network Antimicrobial Stewardship Committee and initially endorsed for SA Health use by the South Australia Medicines Advisory Committee on 19 January 2022, the guidelines have been updated to reflect changes in clinical evidence, national and international guidelines and patient access pathways such as updates to the Pharmaceutical Benefits Scheme (PBS).

Australian guidelines and recommendations

Medication recommendations for COVID-19 can change rapidly due to demand and supply constraints, ongoing research and as novel agents are discovered. For the most up to date Australian guidelines and recommendations refer to:

Patient eligibility criteria

The COVID-19 Medication Management of Mild Illness in the Outpatient Setting Clinical Guideline (PDF 1415KB) provides guidance on patient eligibility criteria and treatment options.

Refer to ATAGI clinical guidance for COVID-19 vaccine providers for the latest updates from ATAGI, including clinical recommendations for COVID-19 vaccines, and information on vaccination status.

Refer your patient

To refer COVID-19 positive adult patients to SA Health for consideration of treatment with available medicines from the Commonwealth’s National Medical Stockpile for the early intervention of COVID-19, complete referrals through the COVID-19 Outpatient Treatment Referral Portal

This process will require information about you as the referrer and will require the patient to be on hand when entering information.

Note: Patients eligible for PBS access to oral antiviral therapy who are clinically appropriate for treatment with oral medication should NOT be referred via this pathway, except where needing specific consideration of NMS treatments not available via PBS (eg. remdesivir or non-Medicare non-PBS  patients ).

Please review the patient education information below and speak to your patient regarding the treatment chosen as part of the referral process.

The following patients should NOT be referred for treatment using this form:

  • Patients who are eligible for PBS supply of oral antiviral treatment AND who are clinically appropriate for treatment with oral medication, except where needing specific consideration of NMS treatments not available via PBS (e.g. remdesivir or monoclonal antibody infusions)
  • Patients under 18 years of age (for children who may require COVID-19 treatment, please discuss with the COVIDKids service at the Women’s and Children’s Hospital), or
  • Patients with a new or increased oxygen requirement. (Note: patients who are ordinarily on oxygen and do not have an increased need ARE eligible for referral).

What happens after the referral is made?

Step 1: Application submitted by referring clinician.

Step 2: Review of application by clinical team (and follow up with referrer, if required).

Step 3: If referral meets the criteria, patients who decide to proceed will be contacted by SA Health staff to discuss treatment options and arrange access to treatment.

Step 4: You will be advised by the relevant treating facility to inform you of the progress of the referral.
