On this episode, I discuss duloxetine pharmacology, adverse effects, and common drug interactions.

Duloxetine is an SNRI that is used for depression, anxiety, and various pain syndromes like neuropathy and fibromyalgia.

Duloxetine can inhibit CYP2D6 which can lead to higher concentrations of clozapine and propranolol and lower activity of tamoxifen.

CYP1A2 inhibitors like ciprofloxacin can raise concentrations of duloxetine leading to an increased potential for adverse effects.
