Timing of Clozapine Levels Levels should be a steady state, trough level. Clozapine reaches a steady-state concentration at 5-7 days. Levels should be drawn 12 hours (± 2 h) after the last dose. Relationship between Clozapine Levels and Efficacy Clozapine blood levels are correlated with both clozapine effectiveness and side effects.

Nov 30, 2016 · It involves measurement of plasma levels of clozapine and norclozapine (N-desmethyl-clozapine, a major metabolite of clozapine) six hours or more after the last dose of the drug (a ‘trough’ sample). Monitoring of clozapine level has been suggested if the dose is 600 mg per day or more,48) which can be done 3 monthly. Author: Nilamadhab Kar, Socorro Barreto, Rahul Chandavarkar Publish Year: 2016

Conclusions: The exact range of clozapine levels that corresponds to toxicity remains unclear. However, levels between 350 µg/L and 1000 µg/L achieved with gradual upward titration are more likely to be effective and less likely to cause toxicity. Ongoing clozapine level monitoring is indicated, especially when (i) prescribing higher doses (> 600 mg/day) of clozapine, (ii) there … Author: Anne Stark, James Scott, James Scott, James Scott Publish Year: 2012

Measure clozapine as steady-state trough levels. I usually draw them 12 hours after the last dose (such as in the morning after the nightly dose) and several days after treatment begins. When you order a clozapine level, most laboratories report 3 numbers: clozapine, norclozapine, and their sum. The literature addresses only the clinical use of clozapine levels and ignores the much …

• it is a trough level • clozapine has reached steady state levels. Time of the last dose has a significant influence on serum clozapine levels and clozapine to NOR ratios. NOR levels are less influenced by the time because it has a longer plasma half-life and shows less day-to-day variation when compared with clozapine. 13

Clozapine levels Clozapine levels are best performed after the initial titration stage, once the dose has been stable for at least a week6. For meaningful results, the sample should be taken as a trough level immediately before the next dose or in the morning after an evening dose. Although clozapine plasma levels are
