If within a few days of the expiration date, I suggest contacting your pharmacist for an opinion. ...Read more

What would happenif you take an expired valtrex (valacyclovir)?

Probably nothing: All medicines degrade with time. Just cause it expired doesn't mean its poisonous. Just won't work as well as unexpired medicine. Actually, it really depends on how old the medicine is. If its relatively soon after the expiration date, I'm sure its still good. All bets are off its over a year past. ...Read more

I have been diagnosed with bells but didn't fill the Valtrex (valacyclovir) prescription due to cost is this going to hinder my recovery in any way?

I have been diagnosed with bells but didn't fill the Valtrex (valacyclovir) prescription due to cost is this going to hinder my recovery in any way?

Maybe not: If your bells' palsy is caused by the reactivation of chicken-pox virus (shingle) or herpes simplex (unusual), Valtrex (valacyclovir) may help but probably won't hinder healing if not taken. Acyclovir is an alternative which is very cheap--less than 20 bucks for 10 days. May need to check for lyme disease too. Please consult doc for re-eval and possible change of med. Good luck. ...Read more
