Qdenga Caution For Usage

Incompatibilities: In the absence of compatibility studies, this medicinal product must not be mixed with other vaccine or medicinal products except for the diluent (solvent) provided.
Instructions for Use/Handling: Instructions for reconstitution of the vaccine with the diluent (solvent) presented in vial: Qdenga is a 2-component vaccine that consists of a vial containing lyophilised vaccine and a vial containing diluent (solvent). The lyophilised vaccine must be reconstituted with diluent prior to administration.
Use only sterile syringes for reconstitution and injection of Qdenga. Qdenga should not be mixed with other vaccines in the same syringe.
To reconstitute Qdenga, use only the diluent (0.22% sodium chloride solution) supplied with the vaccine since it is free of preservatives or other anti-viral substances. Contact with preservatives, antiseptics, detergents, and other anti-viral substances is to be avoided since they may inactivate the vaccine.
Remove the vaccine and diluent (solvent) vials from the refrigerator and place at room temperature for approximately 15 minutes.
Remove the caps from both vials and clean the surface of stoppers on top of the vials using an alcohol wipe.
Attach a sterile needle to a sterile 1 mL syringe and insert the needle into the diluent (solvent) vial. The recommended needle is 23G.
Slowly press the plunger completely down.
Turn the vial upside down, withdraw the entire contents of the vial and continue to pull plunger out to 0.75 mL. A bubble should be seen inside of the syringe.
Remove the needle syringe assembly from the diluent vial.
Invert the syringe to bring the bubble back to the plunger.
Insert the needle of the syringe assembly into the lyophilised vaccine vial.
Direct the flow of the diluent (solvent) toward the side of the vial while slowly depressing the plunger to reduce the chance of forming bubbles.
Release the finger from the plunger and, holding the assembly on a flat surface, gently swirl the vial in both directions with the needle syringe assembly attached.
DO NOT SHAKE. Foam and bubbles may form in the reconstituted product.
Let the vial and syringe assembly sit for a while until the solution becomes clear. This takes about 30-60 seconds.
Following reconstitution, the resulting solution should be clear, colourless to pale yellow, and essentially free of foreign particulates. Discard the vaccine if particulates are present and/or if it appears discoloured.
Withdraw the entire volume of the reconstituted Qdenga solution with the same syringe until an air bubble appears in the syringe.
Remove the needle syringe assembly from the vial.
Hold the syringe with the needle pointing upwards, tap the side of the syringe to bring the air bubble to the top, discard the attached needle and replace with a new sterile needle, expel the air bubble until a small drop of the liquid forms at the top of the needle. The recommended needle is 25G 16 mm.
Qdenga is ready to be administered by subcutaneous injection.
Qdenga should be administered immediately after reconstitution. Chemical and physical in-use stability have been demonstrated for 2 hours from the time of reconstitution of the vaccine vial. After this time period, the vaccine must be discarded. Do not return it to the refrigerator.
Instructions for reconstitution of the vaccine with diluent (solvent) presented in pre-filled syringe: Qdenga is a 2-component vaccine that consists of a vial containing lyophilised vaccine and diluent (solvent) provided in the pre-filled syringe. The lyophilised vaccine must be reconstituted with diluent prior to administration.
Qdenga should not be mixed with other vaccines in the same syringe.
To reconstitute Qdenga, use only the diluent (0.22% sodium chloride solution) in the pre-filled syringe supplied with the vaccine since it is free of preservatives or other anti-viral substances. Contact with preservatives, antiseptics, detergents, and other anti-viral substances is to be avoided since they may inactivate the vaccine.
Remove the vaccine vial and pre-filled syringe diluent (solvent) from the refrigerator and place at room temperature for approximately 15 minutes.
