Product / population
Adult product-specific renal information; not a complete prescribing regimen.
Renal measure
CrCl, mL/min.

RX mirror: this is not independent corroboration of its underlying label. Check dated-label and formulation limitations.

Renal dosing, restrictions and evidence limits

Below CrCl 25 mL/min, use lower individual doses during titration. When an increase is required, increase the individual dose rather than the dosing frequency. The source does not specify a fixed percentage reduction. Monitor for worsening somnolence, dizziness, weakness and dry mouth as possible excess exposure. Keep food administration and formulation consistent. Concomitant strong CYP1A2 inhibitors such as ciprofloxacin or fluvoxamine are contraindicated; renal adjustment does not remove this interaction.
