Scheduled for a colonoscopy monday. have to prep tomorrow . feel a cold sore coming on,on my mouth. ok to take valtrex (valacyclovir) tonite and tomorrow ?

No problem: While Valtrex (valacyclovir) is efficaciaous in treating sores in the mouth it also causes some GI complaints. Since you are taking a bowel prep to clean the bowel prior to colooscopy it might be worth while to take one tab tonight and hold off taking the second unless the inflammation in your mouth becomes much worse and actually interfers with the prep intake.
