Looking over various resources online it says that you should take 4g valacyclovir and 900mg valganciclovir if you have additional coinfections (CMV and HSV6) on top of the an EBV infection. Different resources also say that you should add these drug together the the documents I have that show the doses don't say that explicitly. Is that understanding correct that patients should be adding these mega doses together or, if you have all three infections should you just switch to the 900mg valganciclovir and drop valacyclovir? Does anyone have a resource that shows the dose necessary for adding these drugs together? Should you decrease it by weight? My doctor is willing to try putting me on these drugs but the protocol we have doesn't clarify this. I've looked through the posts on this site but could only find mostly people's personal experiences/doses.
