It increases the neurotransmitter serotonin in your brain to treat depression. Caution should be taken when consuming SSRIs with certain other medications including monoamine oxidase inhibitors and, in some cases, thioridazine or orap.
- Serotonin and norepinephrine reuptake inhibitors (SNRIs): it increases the amount of neurotransmitters serotonin and norepinephrine in your brain to treat depression. This should not be taken with MAOIs or if you should discuss with your doctor before taking SNRIs medications if you are suffering from liver or kidney problems or have narrow-angle glaucoma. Examples of SNRIs include desvenlafaxine (Pristiq, Khedezla), duloxetine (Cymbalta, Irenka), levomilnacipran (Fetzima), milnacipran (Savella), and venlafaxine (Effexor XR).

Use caution if you are suffering from narrow-angle glaucoma. TCAs may cause more severe side effects than SSRIs or SNRIs. Examples of tricyclic antidepressants include amitriptyline, doxepin, imipramine, trimipramine, desipramine, nortriptyline, and protriptyline.
