The following information is intended for healthcare professionals only.
TECHNICAL LEAFLET
Aciclovir 25mg/ml powder for solution for infusion

Special precautions for disposal and other handling
Reconstitution: Aciclovir should be reconstituted using the following volumes of either Water
for Injections or Sodium Chloride 9 mg/ml (0.9% w/v) solution for infusion to provide a solution
containing 25 mg aciclovir per ml:
Formulation

Volume of solution for reconstitution

250 mg vial

10 ml

500 mg vial

20 ml

From the calculated dose, determine the appropriate number and size of vials to be used. To
reconstitute each vial add the recommended volume of infusion solution and shake gently until
the contents of the vial have dissolved completely.
Administration:
After reconstitution Aciclovir may be administered by a controlled-rate infusion pump.
Alternatively, the reconstituted solution may be further diluted to give an aciclovir concentration
of not greater than 5 mg/ml (0.5% w/v) for administration by infusion:
Add the required volume of reconstituted solution to the chosen infusion solution, as
recommended below, and shake well to ensure adequate mixing occurs.
For children and neonates, where it is advisable to keep the volume of infusion solution to a
minimum, it is recommended that dilution is on the basis of 4 ml reconstituted solution (100 mg
aciclovir) added to 20 ml of infusion solution.
For adults, it is recommended that infusion bags containing 100 ml of infusion solution are used,
even when this would give an aciclovir concentration substantially below 0.5% w/v. Thus one
100 ml infusion bag may be used for any dose between 250 mg and 500 mg aciclovir (10 and 20
ml of reconstituted solution) but a second bag must be used for doses between 500 mg and 1000
mg.
When diluted in accordance with the recommended schedules, Aciclovir is known to be
compatible with the following infusion solutions and stable for up to 24 hours at room
temperature (25°C):

Sodium Chloride 4.5 mg/ml (0.45%) and 9 mg/ml (0.9% w/v) solution for infusion
Sodium Chloride 1.8 mg/ml (0.18% w/v) and Glucose (4% w/v) solution for infusion
Sodium Chloride 4.5 mg/ml (0.45% w/v) and Glucose (2.5% w/v) solution for infusion
Compound Sodium Lactate (Hartmann's Solution) solution for infusion.
Aciclovir when diluted in accordance with the above schedule will give an aciclovir
concentration not greater than 0.5% w/v.
This medicinal product is for single use only.
Aciclovir contains no antimicrobial preservative. Reconstitution and dilution should therefore be
carried out under full aseptic conditions immediately before use and any unused solution
discarded. The reconstituted or diluted solutions should not be refrigerated.
The medicinal product is to be visually inspected prior to use (also after dilution). Only clear
solutions practically free from particles should be used. Should any visible turbidity or
crystallisation appear in the solution before or during infusion, the preparation should be
discarded.
Displacement value for the powder is 0.50mL and the final volume in the container after
reconstitution is 10.50mL
Shelf life
2 years
Following dilution: Chemical and physical in-use stability has been demonstrated for 24 hours at
25°C. From a microbiological point of view, the product should be used immediately. If not used

For reconstituted solutions, chemical and physical in-use stability has been demonstrated for at
least 12 hours at 25°C.
