Possibly: But may loose potency after expiration. It is best not to take medications after their expiration date especially if they are long expired.

Will 1 year expired Valtrex (valacyclovir) still work?

Dont take it: Please get a new script, not supposed to take meds expired that long if it was one month expired while you are still not supposed to take that one, a 1 month expired med should usually be ok.
