A member asked:
I accidentally took an expired (18 months ago!) zyrtec pill. should i take the correct (unexpired) one nowbad well or should i wait 24 hours?

Wait: Medication can lose it's effectiveness past expiration date, but I would not expect it to not be effective at all; especially if only 18 months expired. It will not be harmful at all that you took an expired zyrtec. It will probably still be almost as effective as it was prior to expiration, so I would just wait and take a new one at your normal time the next day. Hope this helps!
