Remdesivir has been a successful treatment option for adults and children over the age of 12 since its initial emergency use authorization (EUA) in October 2020. Now, the treatment’s use for children has been granted full FDA approval. It’s available for children and infants over 28 days old and weighing at least 7 pounds who test positive for COVID-19, and are hospitalized or at high risk for severe illness.

“This is exciting news, especially for children under the age of 5 who are not currently eligible for vaccination,” Alok Patel, MD, pediatric hospitalist and clinical assistant professor at Lucile Packard Children’s Hospital, told Verywell. “We are hopeful this will expand access to more patients and provide valuable data in treating children under the age of 12.”

Road to Approval

Remdesivir is an antiviral drug previously developed by Gilead Sciences in partnership with the Centers for Disease Control and Prevention (CDC) and the U.S. Army Medical Research Institute of Infectious Diseases to treat RNA-based viruses including:

Severe acute respiratory syndrome (SARS)Middle East respiratory syndrome (MERS)Ebola outbreak in 2015

With the rapid spread of COVID-19, researchers quickly discovered in clinical trials that remdesivir was effective at interrupting the replication cycle of all variants of COVID-19 including Delta, Omicron and its subsequent subvariants.

It allowed patients to recover from illness five days sooner than those that were given a placebo. To help combat severe COVID-19 illness, the FDA issued an EUA for remdesivir in the fall of 2020.

What to Know About Remdesivir

With the FDA expansion of approval for use in children under 12, remdesivir is now fully FDA-approved. This eliminates its current emergency use standing and paves the way for more patients to access the critical COVID-19 treatment.

While remdesivir, which can only be administered intravenously, is a step in the right direction, not everyone who tests positive for COVID-19 is a candidate for the antiviral drug. Currently, the FDA and Gilead Sciences recommend remdesivir if you meet the following criteria:

Over 28 days old and weighing at least 7 poundsHospitalized with COVID-19Non-hospitalized patients who are at high risk for severe COVID-19 illnessAdministered within seven days of symptom onset 

Infants and children considered at high risk for severe illness include those with:

Weakened immune systemAsthma or chronic lung diseaseDiabetesObesitySickle cell diseaseCongenital heart disease

Health experts have reported that nausea is the most common side effect of remdesivir. Other possible side effects include:

Elevated liver enzymes, which can be a sign of liver injuryAllergic reaction resulting in shortness of breath, swelling around lips and eyes, and changes in heart rate and blood pressure

While remdesivir is a significant addition to the healthcare professional’s toolbox in treating COVID-19, Patel warned that it is not a substitute for the COVID-19 vaccination. Antiviral medication is not designed to prevent infection or the spread of COVID-19, they are used to treat people who are already showing symptoms of the disease.

What Parents Can Do

The approval of remdesivir for the pediatric population helps provide vulnerable kids with effective treatment options to help keep them from developing severe COVID-19 complications.

For parents of small children who test positive for COVID-19 and are at high risk for hospitalization, reaching out to your child’s pediatrician to discuss remdesivir as a treatment option is a key to helping stop symptoms from progressing into severe illness and hospitalization.

While COVID-19 safety precautions continue to be lifted, prevention is still the best way to limit exposure and protect vulnerable populations from contracting the virus. Parents of small children and high-risk individuals should continue to:

Wear a mask in crowded environmentsVaccinate those that are eligibleWash hands frequentlyDisinfect high traffic areasAvoid people who are sick

“This should be a relief to parents of kids younger than 5 who are at high risk,” Patel said. “This doesn’t mean they will be asymptomatic, but it will help the specific patients we are worried about.”
