- Supply MUST be ordered on a named patient basis by pharmacy following initiation by completion of the form attached to this monograph by ward pharmacist.

Available preparations
Veklury 100mg vial
Reconstitution
Water for injection 19ml per 100mg vial (final concentration upon addition is 5mg/ml i.e. 100mg in 20ml)
- Discard the vial if a vacuum doses not pull the sterile water for injection into the vial
- Immediately shake the vial for 30 seconds
- Allow the contents 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 more
- Dilute further prior to administration
Infusion fluids
Sodium chloride 0.9%
Methods of intravenous administration
Intermittent intravenous infusion
- Withdraw and discard a volume of infusion fluid from the bag equal to the volume of drug solution being added
- Add the required volume of drug solution to the infusion bag
- Gently invert the bag 20 times to mix the solution in the bag
- Do not shake
- Infuse over 30 to 120 minutes as per table below. Slower infusion rates, with a maximum infusion time up to 120 minutes can be considered to potentially prevent hypersensitivity reactions
- After the infusion is complete, flush line with at least 30ml Sodium chloride (at the same rate of infusion as the drug was being given at)
- Extravasation is likely to cause tissue damage due to low pH of remdesivir infusion (particularly when diluted in 100ml) -monitor the infusion site (ref 1)

Monitoring
Hypersensitivity reactions
- Infusion-related and anaphylactic reactions have been observed
- Slower infusion rates, with a maximum infusion time up to 120 minutes can be considered to potentially prevent hypersensitivity reactions
- If signs and symptoms of a clinically significant hypersensitivity reaction occur, immediately discontinue administration of the drug and initiate appropriate treatment
Transaminase elevations
- Liver function should be determined prior to starting remdesivir and should be monitored throughout treatment.
