May take a few days: The time it takes the body to process half of the dose is ~5 hours, but the the duration of action of Meclizine is approx 24hrs. If she was having adverse side effects of meclizine, would expect to gradually improve over 1-3 days or so after stopping it, depending on how efficient her body is at processing it.

Discuss w her MD: Many medical conditions and medications side effect can cause old to get confused. So u need to discuss her condition and expectation with her physician. Good luck.
