The following dose adjustments are recommended:
Table 1: Dose adjustment of intravenous aciclovir in adults and adolescents with impaired kidney function

| Patients undergoing hemodialysis | In patients undergoing hemodialysis, the recommended dose (5 or 10 mg/kg) should be reduced by half and administered every 24 hours, with an additional dose after dialysis. |
Table 2: Dose adjustment of intravenous aciclovir in newborns, infants, and children with impaired kidney function
| Creatinine clearance | Dose |
| 25 to 50 ml/min/1.73 m2 | The recommended dose (250 or 500 mg/m2 or 20 mg/kg) should be administered every 12 hours. |
| 10 to 25 ml/min/1.73 m2 | The recommended dose (250 or 500 mg/m2 or 20 mg/kg) should be administered every 24 hours. |

Duration of treatment
Treatment with Aciclovir Altan usually lasts for 5 days, but this may be changed depending on the patient's condition and response to treatment.
Treatment for herpes simplex encephalitis usually lasts for 10 days.
Treatment for neonatal herpes simplex virus infections usually lasts for 14 days for skin and mucous membrane lesions and 21 days for disseminated or central nervous system disease.
The duration of prophylactic treatment with Aciclovir Altan depends on the duration of the risk period.
Administration
The solution is administered intravenously, continuously, but very slowly, over at least one hour.
Reconstitution and/or dilution should be performed immediately before use.
Due to the lack of preservatives, any unused solution should be discarded.
If the solution becomes cloudy or crystals form during or after reconstitution, the solution should be discarded.
Reconstituted or diluted solutions should not be stored in the refrigerator.
Preparation of the solution
The vial of Aciclovir Altan for intravenous administration containing 250 mg of lyophilized aciclovir should be reconstituted by adding 10 ml of water for injection or 0.9% sodium chloride solution for infusion.
After reconstitution, a solution with a concentration of 25 mg/ml is obtained.
Route of administration
Intravenous administration
After reconstitution, the solution is administered using an infusion pump with controlled infusion rate over at least one hour.
Infusion
The reconstituted solution can be further diluted for infusion.
Dilution, total or partial, depending on the dose, should be performed by adding or mixing with at least 50 ml of infusion solution, to obtain a maximum concentration of 0.5% (250 mg/50 ml).
The contents of 2 vials (500 mg of aciclovir) can be added to 100 ml of infusion solution.
If a dose greater than 500 mg is required, a second infusion solution can be used.
Aciclovir is compatible with the following infusion solutions:
sodium chloride 4.5 mg/ml (0.45%) solution
sodium chloride 9 mg/ml (0.9%) solution
sodium chloride 1.8 mg/ml (0.18%) and glucose (4% w/v) solution
sodium chloride 4.5 mg/ml (0.45%) and glucose (2.5% w/v) solution
multi-electrolyte solution (Hartmann's solution)
After adding aciclovir to the infusion solution, it should be shaken well to ensure complete mixing of the contents.
After incorrect administration of intravenous aciclovir, severe swelling of the tissue around the vein may occur, which may be followed by ulceration.
Infusion using a mechanical pump is associated with a higher risk than gravity infusion.
Phlebitis and swelling at the injection site may occur.
