The Half Life of Caffeine in healthy adults is about 5.7 hours [1]. "However, at higher doses (e.g. 250–500mg single dose), the clearance of caffeine is significantly reduced and its elimination half-life is prolonged, indicating non-linearity" [2].

"The t1/2 (beta) was significantly prolonged in women on OCS (10.7 +/- 3.0 hr vs. 6.2 +/- 1.6)" [3] unrelated to weight or height of female participants.
