Fluoxetine is an SSRI used in the management of depression, anxiety, OCD, PTSD, and other psychiatric conditions.

Fluoxetine has a very long half-life which can impact clinical management. I discuss how this matters in this podcast episode.

Fluoxetine inhibits CYP2D6 which can alter the concentrations of many drugs.

Prodrugs like codeine and tamoxifen can have their effects reduced because of fluoxetine. I explain this further in the episode.

By inhibiting CYP2D6 concentrations of many drugs can be raised by the use of fluoxetine.
