What is the treatment for Covid?

COVID-19 Treatment Guidelines

The treatment of COVID-19 should include corticosteroids (dexamethasone 6mg daily for 10 days) for patients requiring oxygen, combined with IL-6 receptor antagonists (tocilizumab) for those with worsening disease, and antivirals like remdesivir for patients with moderate disease requiring oxygen support. 1

Treatment Algorithm Based on Disease Severity

Mild to Moderate COVID-19 (Non-hospitalized patients)

• For high-risk patients diagnosed within 7 days of symptom onset:
  • Remdesivir: 3-day course 1, 2
  • Alternative: Nirmatrelvir/ritonavir if available 1
  • Monoclonal antibodies for unvaccinated or vaccine non-responders 1

Moderate COVID-19 (Hospitalized, requiring oxygen)

• Remdesivir: 200mg IV loading dose on day 1, followed by 100mg IV daily for 5 days 1, 2
• Dexamethasone: 6mg daily for 10 days 1
• Thromboprophylaxis with LMWH 1

Severe COVID-19 (Requiring high-flow oxygen or worsening despite treatment)

• Dexamethasone: 6mg daily for 10 days 1
• Tocilizumab (IL-6 receptor antagonist) 1
• Remdesivir if within 10 days of symptom onset 1, 2
• Consider higher dose thromboprophylaxis 1
• Consider baricitinib (JAK inhibitor) if tocilizumab unavailable 1

Critical COVID-19 (Requiring mechanical ventilation/ECMO)

• Dexamethasone: 6mg daily for 10 days (reduces mortality from 41.4% to 29.3%) 1
• Tocilizumab if evidence of systemic inflammation 1
• Extended course of remdesivir (10 days) 2
• Therapeutic anticoagulation if no contraindications 1

Important Monitoring and Safety Considerations

• Perform hepatic laboratory testing before starting and during treatment with remdesivir 2
• Monitor prothrombin time before and during remdesivir treatment 2
• Abnormal liver function tests are common in COVID-19 and may indicate higher risk for severe disease 1
• Remdesivir should be administered only in settings where healthcare providers have immediate access to medications to treat severe infusion or hypersensitivity reactions 2

Treatment Caveats and Pitfalls

1. Timing matters: Treatment should be initiated as soon as possible after diagnosis of symptomatic COVID-19 2. Delaying treatment until severe symptoms develop may reduce effectiveness.

2. Corticosteroid caution: Dexamethasone should be avoided in patients not requiring oxygen support as it may be harmful in this population 1.

3. Antibiotic overuse: Empiric antibiotics should only be considered if bacterial superinfection is suspected, not routinely 3.

4. Thromboprophylaxis: All hospitalized COVID-19 patients should receive thromboprophylaxis with LMWH, with higher doses for those with additional risk factors (high BMI, history of VTE, active cancer) 1.

5. Discharge considerations: Resolution of fever for >3 days, improvement of respiratory symptoms, and significant absorption of pulmonary lesions on imaging should be considered before discharge 1.

The COVID-19 treatment landscape continues to evolve, but the current evidence strongly supports the use of corticosteroids, antivirals, and immunomodulators as the mainstay of therapy based on disease severity. Early intervention with appropriate therapies has been shown to reduce mortality and improve outcomes in patients with COVID-19.
