What medicines are available to treat an acutely unwell person with COVID-19 in the primary care setting to reduce the risk of hospital admission?
This question will be reassessed on a regular basis due to the fast changing evidence
What the research says:
The monoclonal antibodies casirivimab and imdevimab are recommended by the WHO as a one off dose (subcutaneous or intravenous) for patients with non-severe COVID-19 at the highest risk of hospitalisation (WHO 2021). In the USA, the monoclonal antibody sotrovimab has been granted emergency authorisation* for use in the community setting for the treatment of children aged >12 years and adults with mild-to-moderate COVID-19 illness who are at risk for severe disease (GSK 2021). The oral antiviral agents molnupiravir and ritonavir-boosted nirmatrelvir (Paxlovid) are approved for use in the UK (MHRA, 4 November 2021; MHRA, 31 December 2021), and both agents have been granted emergency use authorisation for use in the USA (CDC 2021), in patients with mild to moderate COVID-19 who are at the beginning of symptom onset and at higher risk of progression to severe disease. A range of medicines are under evaluation for use in primary care with a view to i) symptom relief/control, ii) reducing the likelihood of hospitalisation iii) reducing the need for intensive care unit care and of death.
*An Emergency Use Authorization permits the use of a medical product that has either not yet received regulatory approval or has not received regulatory approval for a specific indication, to be used in an emergency situation to diagnose, treat, or prevent serious or life-threatening diseases or conditions

Although no specific studies have been conducted on the efficacy and safety of paracetamol it remains widely used as part of a standard of care for symptoms of COVID-19, with no reports of safety concerns identified. Similarly, for ibuprofen, despite initial concerns, no data indicating safety concerns exist in the context of COVID-19 infection.
What this means for your clinical practice:
- The monoclonal antibodies casirivimab and imdevimab are recommended by the WHO as a one off dose (subcutaneous or intravenous) for patients with non-severe COVID-19 at the highest risk of hospitalisation.
- In the USA, following FDA emergency authorisation, sotrovimab may be considered for the treatment of children aged >12 years and adults with mild-to-moderate COVID-19 illness who are at risk for severe disease (GSK 2021).
- The oral antiviral agents molnupiravir and ritonavir-boosted nirmatrelvir (Paxlovid) are approved for use in the UK and both have been granted emergency use authorisation for use in the USA.
- Medicinal treatment of acute COVID-19 should currently focus on symptomatic relief.
- Standard antipyretics, paracetamol or ibuprofen, can be used for the management of fever and pain, there is no evidence to suggest they halt progression to more severe disease.
- Diarrhoea and nausea should be managed according to local standard of care.
- Antibiotic stewardship remains important during the COVID-19 pandemic. Antibiotic prophylaxis is not advised and antibiotics should not be prescribed unless there is a clinical suspicion of a bacterial infection
- At the present time there is no evidence to support the use of oral steroids or prophylactic oral anticoagulants for the treatment of patients with COVID-19 in the community setting.
- While a phase 2 study in 146 patients has shown inhaled budesonide used within 7 days of COVID-19 symptom onset reduced the need for hospitalisation, larger studies are ongoing to determine whether this agent is appropriate for routine use in the primary care setting.
