Route of administration

Value:Intravenous

Remdesivir is administered via IV infusion

Remdesivir is indicated for the treatment of COVID-19 in adults and pediatric patients who are hospitalized or at high risk of severe disease progression. It is typically used in patients requiring supplemental oxygen, mechanical ventilation, or extracorporeal membrane oxygenation (ECMO).

Remdesivir is a prodrug that gets converted to its active form inside cells. It acts as an adenosine nucleoside analog that interferes with the viral RNA-dependent RNA polymerase, inhibiting viral replication of SARS-CoV-2.

Remdesivir is administered via intravenous infusion, usually once daily for 5 to 10 days depending on clinical status. Common side effects may include nausea, elevated liver enzymes, and infusion-related reactions. It is contraindicated in patients with known hypersensitivity to the drug. Liver function and renal function should be monitored during treatment. Safety and effectiveness in pediatric patients under 12 years old are still being established.
