Outpatient Treatments for COVID-19

Three antiviral therapies are currently FDA approved or authorized for outpatient treatment of COVID-19 infection and recommended by the NIH COVID-19 Treatment Guidelines Panel. They are not approved for pre- or post-exposure prophylaxis. Importantly, they retain full activity against the current variant mix in California.

Note: The FDA has removed the requirement for a positive SARS-CoV-2 viral test in order to prescribe these medications. Although the agency still strongly recommends the use of viral testing to help diagnose COVID-19 this change allows for providers to consider treatment in the rare instances where an individual with a known exposure who develops signs and symptoms consistent with COVID-19 presents with a negative test. See FDA product specific FAQs for more information.

Antiviral Medication (in order of preference) FDA Status Mode/duration of Administration Start time from symptom onset Age/Weight Fact sheets/FAQs

Remdesivir (Veklury) is the only treatment approved for children under 12 years of age. It is given as an IV infusion for a total of 3 days initiated as soon as possible and within 7 days of symptom onset.

In clinical trials, remdesivir reduced the risk of hospitalization or death by 87% among high-risk unvaccinated patients with COVID-19 treated within 7 days of symptom onset (Gottlieb, 2021).

Given the emergence of variants resistant to mAbs, providing remdesivir in the outpatient setting may be of particular importance for facilities and providers that see large numbers of immunosuppressed patients such as transplant and oncology centers, or high-risk pediatric populations. Providers are encouraged to order remdesivir to have on hand for patients unable to take Paxlovid.

  • FDA approved for the treatment of COVID-19 in adults and pediatric patients (28 days of age and older weighing at least 3 kilograms) who are:
    • Hospitalized, or
    • Not hospitalized and have mild-moderate COVID-19 and are at high risk for progression to severe COVID-19, including hospitalization and death.
      Note: In December 2022, the FDA revised the remdesivir labeling to remove having a positive SARS-CoV-2 viral test result from the indication.
  • For information regarding purchasing or how to access remdesivir, please email remdesivir@amerisourcebergen.com, or call 1-800-746-6273 or reach out directly to your AmerisourceBergen representative.
  • HHS is asking providers who administer outpatient Veklury (remdesivir) to add their infusion site to the COVID-19 Therapeutics Locator in order to improve public awareness and product access. Only information provided by the infusion site will be visible on the locator. Infusion sites can opt out of being on the locator at any time. Infusion sites can learn more and opt into the therapeutics locator here.
  • CMS has created the Healthcare Common Procedure Coding System (HCPCS) code J0248 for reimbursement when administered in an outpatient setting. This code is available for use by all payers and is effective for dates of service on or after December 23, 2021. Additional information is available here.

Molnupiravir (Lagevrio)

Molnupiravir (Lagevrio) is authorized as an alternative therapy when Paxlovid and remdesivir are not available, feasible to use, or clinically appropriate. It is given as 800 mg (four 200 mg capsules) taken orally every 12 hours for 5 days. Treatment started as soon as possible after diagnosis of COVID-19 and within 5 days of symptom onset.

  • Molnupiravir is a nucleoside analogue that inhibits SARS-CoV-2 replication by viral mutagenesis.
  • Due to concern for side effects and decreased risk reduction compared to other available medications, molnupiravir should only be used if other treatments are not available or not clinically appropriate.
  • Guidance is now available on the provider fact sheet for the preparation and administration of molnupiravir via nasogastric and orogastric tube.
  • Several studies have shown a risk reduction in severe disease after molnupiravir treatment with the most significant benefit in those at highest risk or elderly (≥75 years of age). In addition, there is evidence of more rapid symptom resolution and viral load reductions in people treated with molnupiravir. See table below.
  • Use in adults 18 and older only. Not recommended in pregnancy. If the provider and patient choose to use the product during pregnancy, it is advised that the patient be registered in the Merck Pregnancy Surveillance Program.
  • Females of childbearing potential should use a reliable method of contraception correctly and consistently, as applicable, for the duration of treatment and for 4 days after the last dose of molnupiravir.
  • Males of reproductive potential who are sexually active with females of childbearing potential should use a reliable method of contraception correctly and consistently during treatment and for at least 3 months after the last dose.
  • Providers should carefully review the Fact sheet for health providers before prescribing to ensure that the patient’s condition warrants treatment, that there are no drug interactions, and that there are contraindications to therapy.
