Remdesivir | Covid-19 Treatment

EMA recommends authorisation for remdesivir to combat COVID-19

Generic name: remdesivir (rem DES i veer)

Remdesivir is used to treat people with coronavirus disease 2019 (COVID-19) who are in a hospital.

Remdesivir is approved for use in adults and children at least 12 years old who weigh at least 88 pounds (40 kilograms).

The US Food and Drug Administration (FDA) has authorized emergency use of remdesivir in children younger than 12 years old who weigh at least 8 pounds (3.5 kg) and are hospitalized with COVID-19. Remdesivir has not been FDA-approved to treat COVID-19 in these younger patients, especially outside of a hospital.

Remdesivir may also be used for purposes not listed in this medication guide.


Remdesivir is for use only in people with COVID-19 who are in a hospital. You must remain under the care of a doctor while receiving remdesivir.

Before taking this medicine

You should not be treated with remdesivir if you are allergic to it.

Tell your doctor if you have ever had:

  • liver disease; or
  • kidney disease.

Tell your doctor if you are pregnant or plan to become pregnant, or if you are breastfeeding.

How is remdesivir given?

Your doctor will perform blood tests to make sure you do not have conditions that would prevent you from safely using remdesivir.

Remdesivir is given as an infusion into a vein. A healthcare provider will give you this injection.

remdesivir must be given slowly, and the infusion can take 30 to 120 minutes to complete.

Remdesivir is usually given once per day for 5 to 10 days.

You will need frequent blood tests to check your liver function.

You must remain under the care of a doctor while you are being treated with remdesivir for COVID-19.

What happens if I miss a dose?

Because you will receive remdesivir in a clinical setting, you are not likely to miss a dose.

What happens if I overdose?

Since remdesivir is given by a healthcare professional in a medical setting, you will be treated quickly if an overdose occurs.

What should I avoid while receiving remdesivir?

Follow your doctor's instructions about any restrictions on food, beverages, or activity.

For Healthcare Professionals

Applies to remdesivir: intravenous powder for injection, intravenous solution


The most common side effect in healthy subjects was increased transaminases. The most common side effects in patients with coronavirus disease 2019 (COVID-19) were nausea, increased AST, and increased ALT.


In studies in healthy subjects, increases in ALT, AST, or both in those who received this drug were grade 1 (10%) or grade 2 (4%). In a clinical study of patients with COVID-19, the incidence of at least grade 3 nonserious side effects of increased aminotransferase levels (including ALT, AST, or both) was 4% with this drug compared to 6% with placebo. In a clinical trial in hospitalized patients with severe COVID-19 receiving this drug for 5 or 10 days, any grade (at least 1.25 times the upper limit of normal [1.25 x ULN]) laboratory abnormalities of increased AST and increased ALT were reported in 40% and 42% of patients, respectively; at least grade 3 (at least 5 x ULN) laboratory abnormalities of increased AST and increased ALT were both reported in 7% of patients. In a clinical trial in hospitalized patients with moderate COVID-19 receiving this drug for 5 or 10 days compared to standard of care, any grade laboratory abnormalities of increased AST and increased ALT occurred in 32% and 33% of patients, respectively, receiving this drug and 33% and 39% of patients, respectively, receiving standard of care; at least grade 3 laboratory abnormalities of increased AST and increased ALT occurred in 2% and 3% of patients, respectively, receiving this drug and 6% and 7%, respectively, receiving standard of care.

Very common (10% or more): Increased transaminases, increased ALT, increased AST

Common (1% to 10%): Increased aminotransferase levels (including ALT, AST, or both), increased bilirubin

Uncommon (0.1% to 1%): Increased hepatic enzyme, hypertransaminasemia, increased liver function tests


Very common (10% or more): Decreased CrCl (based on Cockcroft-Gault formula; up to 19%), decreased estimated glomerular filtration rate (eGFR; up to 18%), increased creatinine (up to 15%)

Uncommon (0.1% to 1%): Decreased GFR, acute kidney injury

What other drugs will affect remdesivir?

Tell your doctor if you also take chloroquine or hydroxychloroquine. Either of these other medicines could make remdesivir less effective.

Other drugs may affect remdesivir, including prescription and over-the-counter medicines, vitamins, and herbal products. Tell your doctor about all your current medicines and any medicine you start or stop using.

Considerations in Pregnancy

  • Pregnant patients were excluded from the clinical trials that evaluated the safety and efficacy of remdesivir for the treatment of COVID-19, but preliminary reports of remdesivir use in pregnant patients from the remdesivir compassionate use program are reassuring.
  • Among 86 pregnant and postpartum hospitalized patients with severe COVID-19 who received compassionate use remdesivir, the therapy was well tolerated, with a low rate of serious adverse events.8
  • Remdesivir should not be withheld from pregnant patients if it is otherwise indicated.

Considerations in Children

  • The safety and effectiveness of using remdesivir to treat COVID-19 have not been evaluated in pediatric patients aged <12 years or weighing <40 kg.
  • Remdesivir is available through an FDA EUA for the treatment of COVID-19 in hospitalized pediatric patients weighing 3.5 kg to <40 kg or aged <12 years and weighing ≥3.5 kg.
  • A clinical trial is currently evaluating the pharmacokinetics of remdesivir in children ( Identifier NCT04431453).

Clinical Trials

Several clinical trials that are evaluating the use of remdesivir for the treatment of COVID-19 are currently underway or in development.
