Remdesivir

Renal Impairment No dosage adjustment of VEKLURY is recommended in patients with any degree of renal impairment, including patients on dialysis. VEKLURY may be administered without regard to the timing of dialysis [see Dosage and Administration and Use in Specific Populations (8.4 , 8.6) ].

Testing Before Starting and During Treatment with VEKLURY Perform hepatic laboratory testing in all patients before starting VEKLURY and while receiving VEKLURY as clinically appropriate [see Warnings and Precautions and Use in Specific Populations ]. Determine prothrombin time in all patients before starting VEKLURY and monitor while receiving VEKLURY as clinically appropriate [see Adverse Reactions ].

Dosage and Administration Overview VEKLURY may only be administered in settings in which healthcare providers have immediate access to medications to treat a severe infusion or hypersensitivity reaction, such as anaphylaxis, and the ability to activate the emergency medical system (EMS), as necessary [see Dosage and Administration , Warnings and Precautions ] .

Administer VEKLURY for the treatment of COVID-19 in adults and pediatric patients (birth to less than 18 years of age weighing at least 1.5 kg) by intravenous infusion only. Do not administer by any other route. VEKLURY for injection must be reconstituted with Sterile Water for Injection prior to diluting with 0.9% sodium chloride injection.

Dosage Preparation and Administration Reconstitution Instructions Remove the required number of single-dose vial(s) from storage. For each vial: Inspect the vial to ensure the container closure is free from defects. Aseptically reconstitute VEKLURY lyophilized powder by adding 19 mL of Sterile Water for Injection using a suitably sized syringe and needle per vial, and insert the needle in the center of the vial stopper.

Only use Sterile Water for Injection to reconstitute VEKLURY lyophilized powder. Discard the vial if a vacuum does not pull the Sterile Water for Injection into the vial. Immediately shake the vial for 30 seconds. Allow the contents of the vial to settle for 2 to 3 minutes. A clear, colorless to yellow solution, free of visible particles, should result.

If the contents of the vial are not completely dissolved, shake the vial again for 30 seconds and allow the contents to settle for 2 to 3 minutes. Repeat this procedure as necessary until the contents of the vial are completely dissolved. Discard the vial if the contents are not completely dissolved. Following reconstitution, each vial contains 100 mg/20 mL (5 mg/mL) of remdesivir solution.

Use reconstituted product immediately to prepare the diluted drug product. Detailed dilution and administration instruction based on patient’s weight is provided below. Dilution Instructions for Adults and Pediatric Patients Weighing at Least 40 kg Care should be taken during admixture to prevent inadvertent microbial contamination.

As there is no preservative or bacteriostatic agent present in this product, aseptic technique must be used in preparation of the final parenteral solution. It is always recommended to administer intravenous medication immediately after preparation when possible. Reconstituted VEKLURY for injection, containing 100 mg/20 mL remdesivir solution, must be further diluted in either a 100 mL or 250 mL 0.9% sodium chloride injection infusion bag.

Inspect the reconstituted VEKLURY for injection vial to ensure the solution is free of particulate matter. Withdraw the required volume of reconstituted VEKLURY for injection from the VEKLURY vial following instructions in Table 2, using an appropriately sized syringe. Discard any unused portion remaining in the reconstituted vial.

Transfer the required volume of reconstituted VEKLURY for injection to the selected infusion bag. Gently invert the bag 20 times to mix the solution in the bag. Do not shake. The prepared infusion solution can be stored for 24 hours at room temperature (20°C to 25°C [68°F to 77°F]) or 48 hours at refrigerated temperature (2°C to 8°C [36°F to 46°F]) prior to administration.

Administration Instructions for Adults and Pediatric Patients Weighing at Least 40 kg Do not administer the prepared diluted solution simultaneously with any other medication. The compatibility of VEKLURY injection with intravenous solutions and medications other than 0.9% sodium chloride injection, USP is not known. Administer VEKLURY via intravenous infusion over 30 to 120 minutes.

Administration should be under conditions where management of severe hypersensitivity reactions, such as anaphylaxis, is possible. Monitor patients during infusion and observe patients for at least one hour after infusion is complete for signs and symptoms of hypersensitivity as clinically appropriate [see Warnings and Precautions ] .

Administer the diluted solution with the infusion rate described in Table 3. [See table below.] Dilution Instructions for Pediatric Patients (Birth to Less than 18 Years of Age) Weighing 1.5 kg to Less than 40 kg Care should be taken during admixture to prevent inadvertent microbial contamination. As there is no preservative or bacteriostatic agent present in this product, aseptic technique must be used in preparation of the final parenteral solution.

It is always recommended to administer intravenous medication immediately after preparation when possible. Inspect the reconstituted VEKLURY for injection vial to ensure the reconstituted solution is free of particulate matter. For pediatric patients (birth to less than 18 years of age) weighing 1.5 kg to less than 40 kg, the 100 mg/20 mL (5 mg/mL) remdesivir reconstituted solution should be further diluted to a fixed concentration of 1.25 mg/mL using 0.9% sodium chloride injection.

The final required infusion volume concentration of 1.25 mg/mL remdesivir diluted solution for infusion is based on the pediatric weight-based dosing regimens. Small 0.9% sodium chloride injection infusion bags (e.g., 25, 50, or 100 mL) or an appropriately sized syringe should be used for pediatric dosing. The recommended dose is administered via intravenous infusion in a total volume dependent on the dose to yield the target remdesivir concentration of 1.25 mg/mL.

A syringe and syringe pump may be used for infusion volumes less than 50 mL. Infusion with IV Bag Determine the total infusion volume needed to achieve a final infusion volume concentration of 1.25 mg/mL of remdesivir diluted solution based on the patient's calculated dose. Select an appropriately sized infusion bag (either prefilled with 0.9% sodium chloride injection or empty) to prepare VEKLURY diluted solution.

If using a prefilled 0.9% sodium chloride injection infusion bag, withdraw and discard the amount of diluent equal to the volume of reconstituted VEKLURY solution needed per patient's dose plus a quantity sufficient to achieve a 1.25 mg/mL final volume concentration of remdesivir diluted solution. Withdraw the required volume of reconstituted VEKLURY solution into an appropriately sized syringe.

Transfer the required volume of reconstituted VEKLURY solution to the 0.9% sodium chloride injection infusion bag. Gently invert the bag 20 times to mix the solution in the bag. Do not shake. If using an empty infusion bag, transfer the required volume of reconstituted VEKLURY solution to the bag, followed by a volume of 0.9% sodium chloride injection sufficient to achieve a 1.25 mg/mL final volume concentration of remdesivir diluted solution.

The prepared infusion solution is stable for 24 hours at room temperature (20°C to 25°C [68°F to 77°F]) or 48 hours at refrigerated temperature (2°C to 8°C [36°F to 46°F]). Infusion with Syringe Determine the total infusion volume needed to achieve a final infusion volume concentration of 1.25 mg/mL of remdesivir diluted solution based on patient's calculated dose.

Select an appropriately sized syringe equal to or larger than the calculated total infusion volume of 1.25 mg/mL remdesivir solution needed. Withdraw the required volume of reconstituted VEKLURY solution from the vial into the syringe based on patient's calculated dose, followed by the required volume of 0.9% sodium chloride injection needed to achieve a 1.25 mg/mL final volume concentration of remdesivir diluted solution.

Gently invert the syringe 20 times to mix the solution in the syringe. Do not shake. The prepared diluted solution should be used immediately. Administration Instructions for Pediatric Patients (Birth to Less than 18 Years of Age) Weighing 1.5 kg to Less than 40 kg The prepared diluted solution should not be administered simultaneously with any other medication.

The compatibility of VEKLURY with IV solutions and medications other than 0.9% sodium chloride injection, USP is not known. Administer VEKLURY via intravenous infusion over 30 to 120 minutes. The rate of infusion (mL/min) should be calculated based on the total infusion volume and total infusion time. Administration should be under conditions where management of severe hypersensitivity reactions, such as anaphylaxis, is possible.

Monitor patients during infusion and observe patients for at least one hour after infusion is complete for signs and symptoms of hypersensitivity as clinically appropriate [see Warnings and Precautions ] .

Storage of Prepared Dosages After reconstitution, use vials immediately to prepare diluted solution. The diluted VEKLURY solution in the infusion bags can be stored up to 24 hours at room temperature (20°C to 25°C [68°F to 77°F]) prior to administration or 48 hours at refrigerated temperature (2°C to 8°C [36°F to 46°F]).

IMPORTANT: This product contains no preservative. Any unused portion of a single-dose VEKLURY vial should be discarded after a diluted solution is prepared.
