Renal dosing, restrictions and evidence limits
At CrCl 60-89 or 30-59, reduce the total daily dose by 25-50%. In severe impairment below 30 or hemodialysis, reduce by 50% or more. Renal clearance varies substantially, so further individualization may be necessary. Tapering and withdrawal precautions remain separate from this renal adjustment. The percentage rule does not establish that every extended-release presentation can deliver the required dose.
