Here you go and notice that age is a factor in the half-life of this drug so for safety purpose's I would use the one close to your age group.compared with subjects 18 to 45 years old. Inter-subject variability in AUC∞ was higher in elderly subjects than in healthy adult subjects 18 to 45 years (58% and 37%, respectively). The mean half-life value was longer in subjects ≥65 years old than in subjects 18 to 45 years old (34.4 hours versus 23.5 hours) like up to 45 a week would be close enough to be out of your system and if 65 years old could be as long as 12 to 14 days to clear your system.. good luck

SO ANYWAY you look at it the best is think of it as 1 to 2 weeks for it to be all out of your system. free discount card
