How Duloxetine Works

Duloxetine works by increasing the levels of serotonin and norepinephrine, two natural substances in the brain that help maintain mental balance and stop the movement of pain signals in the brain.

By blocking the reuptake of these neurotransmitters, it helps improve mood and reduce pain perception.

This dual action makes it effective for treating both mood disorders and certain types of pain.
