Simplovir 250 IV Infusion

It is recommended that Acyclovir IV Injection for Intravenous Infusion should be administered for five to seven days in the treatment of most infections and for at least ten days in the treatment of Herpes simplex encephalitis.

Acyclovir IV Injection after reconstitution may be injected directly into a vein over one hour by a controlled-rate infusion pump or be further diluted for administration by infusion. For intravenous infusion each vial of Acyclovir IV Injection should be reconstituted and then, wholly or in part according to the dosage required, added to and mixed with at least 50 mL-100 ml infusion solution. A maximum of 250 mg & 500 mg of Acyclovir may be added to 50 ml & 100 ml infusion solution respectively. After addition of Acyclovir IV Injection to an infusion solution the mixture should be shaken to ensure thorough mixing. Acyclovir IV Injection when diluted in accordance with the above schedule will give an Acyclovir concentration not greater than 0.5% w/v.

Acyclovir IV Injection is known to be compatible with the following infusion fluids and stable for up to 12 hours at room temperature (below 25°C) when diluted to a concentration not greater than 0.5% w/v Acyclovir.
