5
Q
digoxin level
A
The correct answer is At least 6 hours after last dose. Digoxin has a large volume of distribution and requires time to equilibrate between the blood and tissues. This process takes approximately six hours, so taking a sample before this time will not give an accurate reflection of the steady-state concentration in the body.
