Acyclovir dosage for Hand Foot Mouth

[dasu]

My two kids had IVIG December 2014 and have gradually been improving. However, they got an infection of some kind in early February causing a flare. Per Dr L's instruction we did a 5 day steroid burst, and symptoms remitted. Last week we noticed symptoms beginning to increase again and then noticed classic signs of hand foot and mouth - sores on hands, feet and mouth. It hit us parents too. Our local physician prescribed Acyclovir 600 mG 4x day = 2.4G/day to be taken for one week. They are 72 and 54 pounds. I noticed from other posts here that most prescriptions were for longer periods - 10 or 20 days, and seemingly lower dosage, although weight was not recorded.

 

Should we ask our doctor for a lower dose and longer duration? Also the steroids were prescribed for use at our discretion, for use during a flare caused by an infection post-IVIG. Is it recommended to do another burst just 3 weeks after our last burst?
