If that enzyme is inhibited while you have alprazolam in your system, it will remain more active than it otherwise would have. That is to say, its half-life will be extended. If you take the grapefruit before the alprazolam, you will have an additional effect, as 3A4 also exists in the intestinal wall. You will have an effect as if you took more alprazolam than you actually did, and, you will have the prolonged effect due to the extended half-life.
The grapefruit effect might last as long as 24 hours, or as little as six hours, depending both on dose and your own genetic makeup.
