1. What Aciclovir is and what it is used for
Aciclovir contains a medicine called aciclovir. This belongs to a group of medicines
called antivirals. It works by killing or stopping the growth of viruses.
Aciclovir can be used to:
• treat Varicella Zoster infestations (chickenpox).
• treat severe cases of genital herpes.
• prevent and treat Herpes Simplex infections (cold sores and genital herpes) in people whose immune systems work less well, which means their bodies are less able to fight infections.
• treat Herpes Simplex infections in children up to 3 months of age. This can rarely be caused by the virus responsible for cold sore infection and genital herpes.
• treat Herpes encephalitis (inflammation of the brain. This can rarely be caused by the virus responsible for cold sore infection and genital herpes).

The following information is intended for healthcare professionals only:
Shelf-life on the in-use stability after reconstitution and dilution
Chemical and physical in-use stability has been demonstrated for 12 hours at 15° - 25°C.
From a microbiological point of view, the product should be used immediately. If not used immediately, in-use storage times and conditions prior to use are the responsibility of the user.
Special precautions for disposal and other handling
Reconstitution:
Aciclovir should be reconstituted using the following volumes of either Water for Injections or Sodium Chloride Intravenous Injection (0.9% w/v) to provide a solution containing 25 mg aciclovir per ml:
Formulation Volume of fluid for reconstitution 250 mg vial 10 ml
500 mg vial 20 ml
From the calculated dose, determine the appropriate number and strength of vials to be used. To reconstitute each vial add the recommended volume of infusion fluid and shake gently until the contents of the vial have dissolved completely.
Administration:
The required dose of Aciclovir should be administered by slow intravenous infusion over a one-hour period.
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 fluid 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 fluid.
For adults, it is recommended that infusion bags containing 100 ml of infusion fluid 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 fluids and stable for up to 12 hours at room temperature (15°C to 25°C):
• Sodium Chloride Intravenous Infusion (0.45% and 0.9% w/v)
• Sodium Chloride (0.18% w/v) and Glucose (4% w/v) Intravenous Infusion
• Sodium Chloride (0.45% w/v) and Glucose (2.5% w/v) Intravenous Infusion
• Compound Sodium Lactate Intravenous Infusion (Hartmann's Solution).
Aciclovir when diluted in accordance with the above schedule will give an aciclovir concentration not greater than 0.5% w/v.
Since no antimicrobial preservative is included, reconstitution and dilution must be carried out under full aseptic conditions, immediately before use, and any unused solution discarded.
The reconstituted or diluted solutions should not be refrigerated.
Should any visible turbidity or crystallisation appear in the solution before or during infusion, the preparation should be discarded.
