How long are etodolac pills safe to use after expiring date?

Well common sense tells me that the expiring date is there to notify you of when the pills are no longer safe to use, but since your talking about anti-flammatory pills that are nonsteroidal I would give them a month of leniency time.

I would suggest that you discard the pills once they expire as manufacturers do not guarantee the quality or efficacy of pills past their expiry date.
