More information
- Caution with this switch is necessary, because fluvoxamine slows the metabolism of mirtazapine via CYP1A2, CYP2C9, CYP2D6 and CYP3A4.
- ↑ Switches are based on literature references on this page and expert opinions of the authors. The authors have used pharmacokinetic and receptor affinity properties to determine the switch schedules
