CMV Prophylaxis
"I am immune-compromised from ME/CFS for 17 years. This drug at a dose of 1500 mg/day restored my cognitive clarity to 100%.  At only 1000 mg/day my cognitive clarity fell off substantially...a 20 point IQ drop, perhaps.  When my MD took away my Valtrex one time because she thought my kidneys were at risk after I had white cells in a urine test, I became pseudo-demented and had to use a three-wheeled walker without Valtrex!  I also have vestibular migraine that is treated with 350 mg/day of topamax  and it gets worse without the Valtrex. As soon as I went back on the Valtrex, I perked up immediately and didn&#039;t need the walker."
