I took a valacyclovir 500 mg tablet that expired 8/8/15. will the medicine still be effective?

No!: The expiration date is the date up until which the drug manufacturer can guarantee that the medicine is fully potent and that it is safe to take based on product testing. Therefore you should discard the medicine after the expiration date and have it replaced if you still need it. I wish you well with your health!
