What it is and what it is used for

for

The active substance in Veklury is remdesivir. It is an antiviral medicine used for treating COVID-19. COVID-19 is caused by a virus called a coronavirus. Veklury stops the virus multiplying in cells and this stops the virus multiplying in the body. This can help your body to overcome the virus infection, and may help you get better faster. Veklury will be given to treat COVID-19 in adults and children (who are at least 4 weeks of age and weighing at least 3 kg):  who have pneumonia, and need extra oxygen to help them breathe, but who are not on artificial ventilation (where mechanical means are used to assist or replace spontaneous breathing at start of treatment).  who do not need extra oxygen to help them breathe and are at increased risk for progressing to severe COVID-19. 2.

What you need to know before you take it

Veklury

You will not usually be given Veklury:  if you are allergic to remdesivir, or any of the other ingredients of this medicine (listed in section 6)  Talk to your doctor or nurse as soon as possible, if this applies to you. Warnings and precautions Talk to your doctor or nurse before starting on Veklury:  if you have kidney problems. Your doctor may monitor you if you have kidney problems to ensure your safety.  If you are immunocompromised. Your doctor may monitor you more closely if your immune system is not working properly to ensure the treatment is working.

Reactions following the infusion Veklury can cause allergic reactions following and during the infusion, including anaphylactic reactions (sudden life-threatening allergic reactions). Allergic reactions have been seen rarely. For anaphylactic reactions frequency cannot be estimated from the available data. Symptoms can include:  Changes to blood pressure or heart rate  Low oxygen level in blood  High temperature  Shortness of breath, wheezing  Swelling of the face, lips, tongue or throat (angioedema)  Rash  Feeling sick (nausea)  Being sick (vomiting)  Sweating  Shivering  Tell your doctor or nurse straight away if you notice any of these effects. Blood tests before and during treatment If you are prescribed Veklury, you may be given blood tests before treatment starts. Patients being treated with Veklury may have blood tests during their treatment as determined by their healthcare professional. These tests are to check for kidney problems. Children and adolescents Veklury is not to be given to children under 4 weeks old or to children who weigh less than 3 kg. Not enough is known for it to be given to these children. Other medicines and Veklury Tell your doctor or nurse about any other medicines you are taking, or have recently taken. Do not take chloroquine or hydroxychloroquine at the same time as Veklury.  Tell your doctor if you are taking any of these medicines Pregnancy and breast-feeding Tell your doctor or nurse if you are pregnant, or if you might be. There is not enough information to be sure that Veklury is safe for use in first trimester of pregnancy. Veklury will only be given if the potential benefits of treatment outweigh the potential risks to the mother and the unborn child. Discuss with your doctor the need to use effective contraception during treatment with Veklury. Tell your doctor or nurse if you are breast-feeding. Veklury passes into human breast milk in very small amounts. Because there is limited experience with use during breast-feeding, you should carefully discuss with your doctor whether to continue or interrupt breast-feeding during treatment with Veklury. Driving and using machines Veklury is not expected to have any effect on your ability to drive. Veklury contains a cyclodextrin This medicine contains 3 g betadex sulfobutyl ether sodium in each 100 mg dose of Veklury (6 g in the starting dose). This ingredient is a cyclodextrin emulsifier that helps the medicine to disperse in the body.

Veklury contains sodium This medicine contains 212 mg sodium (main component of cooking/table salt) in each 100 mg dose unit. This is equivalent to 10.6 % of the recommended maximum daily dietary intake of sodium for an adult.

Possible side effects

. Reconstitute the powder For each single-use vial, the powder must be reconstituted and then diluted under aseptic conditions.  Add 19 mL of sterile water for injections to the vial, using a suitably sized syringe and needle for each vial, and insert the needle in the centre of the vial stopper.  This produces a solution of 5 mg/mL of remdesivir. ◦ Discard the vial if a vacuum does not pull the sterile water into the vial.  Only use sterile water for injection to reconstitute remdesivir powder.  Immediately shake the vial for 30 seconds.  Allow the contents of the vial to settle for 2 to 3 minutes. A clear solution 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.  Inspect the vial to ensure the container closure is free from defects.  The solution should only be used if it is clear and free from particles.  Dilute immediately after reconstitution. Dilute the concentrate with sodium chloride solution Reconstituted Veklury must be diluted with sodium chloride 9 mg/mL (0.9%) solution for injection under aseptic conditions. Dilution instructions for adults and paediatric patients weighing at least 40 kg Using Table 3, decide how much sodium chloride solution 9 mg/mL (0.9%) to withdraw from the infusion bag.

Note: 100 mL infusion should only be used for patients with severe fluid restrictions.

    

Withdraw and discard the required volume of sodium chloride solution from the infusion bag using an appropriately sized syringe and needle. See Table 3. Withdraw the required volume of reconstituted Veklury from the vial using an appropriately sized syringe. See Table 3. Transfer the reconstituted Veklury to the infusion bag. Gently invert the bag 20 times to mix the solution in the bag. Do not shake. Administer the diluted solution immediately, or as soon as possible after preparation. The diluted solution is stable for 24 hours at room temperature (20°C to 25°C) or 48 hours in a fridge (2°C to 8°C).

Dilution instructions for paediatric patients at least 4 weeks of age and weighing at least 3 kg but less than 40 kg   



Further dilute the 100 mg/20 mL (5 mg/mL) remdesivir concentrate to a fixed concentration of 1.25 mg/mL using 0.9% sodium chloride. The total required infusion volume of the 1.25 mg/mL remdesivir solution for infusion is calculated from the paediatric weight-based dosing regimens of 5 mg/kg for the loading dose and 2.5 mg/kg for each maintenance dose. Small 0.9% sodium chloride infusion bags (e.g., 25, 50, or 100 mL) or an appropriately sized syringe should be used for paediatric dosing. The recommended dose is administered via IV infusion in a total volume dependent on the dose to yield the target remdesivir concentration of 1.25 mg/mL. A syringe may be used for delivering volumes < 50 mL.

Administer the infusion    

Use under conditions where treatment of severe hypersensitivity reactions, including anaphylaxis, is possible. Administer the diluted solution over 30 to 120 minutes at the rate described in Table 4 or Table 5. After infusion is complete, flush with at least 30 mL of 9 mg/mL (0.9%) sodium chloride solution. The diluted solution should not be administered simultaneously with any other medicines in the same intravenous line. The compatibility of Veklury with IV solutions and medications other than sodium chloride is not known.
