Duloxetine is also called cymbalta and is for major depressive disorder and anxiety disorder and pain associated with depression.
it might not be the right medication for your intermittent explosive disorder.
you might benefit from another type of medication such as an SSRIs such as fluoxetine, fluvoxamine, or sertraline
and a GABAergic mood stabilizer or anticonvulsive drugs such as gabapentin, lithium, carbamazepine, or divalproex might help stabilize your moods better.
I would talk to your doctor about these other drug options to help your condition.
let me know if you have other questions.
I am glad you are reaching out for additional hepl.
