Thank you for your query at AskTheDoctor.com
I understand your concern.
The rate of the metabolism of the drug differs, as if she is taking it for the first time, it will be rapidly metabolised, while if she is habituated, the metabolism will be slower.
So, since this is the first time, it won't be present in her blood stream more than a week.
Hope this was helpful,
