As with most other drugs, serum levels should not be checked until drug concentrations have reached steady state, the point at which drug absorption equals drug clearance.Digoxin has an average half-life of 38 hours, so levels should be drawn five to seven days after initiation or changes in digoxin dose.In patients with renal failure, half-life may be prolonged, consequently delaying the time to reach steady state.he has no complaints and is requesting refills for her digoxin 0.125 mg daily, lisinopril 20 mg daily, metoprolol 50 mg twice daily and glyburide 10 mg daily.
