Can eczema flare-up be due to valtrex or yeast die-off?

[Guest guest]

Cade has eczema that I can keep under control but never goes away. 8

days ago I started him on Diflucan because he was getting extremely

OCD, he was frustrated and pitching fits, he just wasn't himself and I

thought it might be yeast. Within 2 days I saw a big change--his

behavior was wonderful (I was afraid he would be horrible because of

die-off). He still has some OCD things going on but they're not as

severe. Anyway, I started him on Valtrex yesterday morning (250 mg 2x

a day for a week, then upping it to 250 mg 3x a day). By yesterday

evening, his eczema had flared up really bad. It's very red and has

spread to places it's never been before. He also had splotchy red

cheeks today as well (but I don't think it was eczema). This is the

worst it's been in a looong time. I'm wondering if this could be

related to the Valtrex or maybe from the Diflucan? He's also just

getting over a slight cold so maybe that has something to do with it?

Thanks for any input you can give!
