What is Cymbalta?

Cymbalta is an SNRI known as duloxetine in its generic form. SNRIs block the reabsorption of neurotransmitters like serotonin and norepinephrine, which contribute to our overall mood and energy. When reuptake is stopped, higher levels of these neurotransmitters in our system help us feel better and more energized.

Common Doses and Forms of Cymbalta

Cymbalta comes as a delayed-release capsule, and your dosage varies based on your current symptoms, health history, and the recommendation of your care provider. Always take Cymbalta exactly as prescribed to avoid adverse side effects.

For people experiencing depression, you may be prescribed 30 to 60 mg a day. If you have anxiety symptoms, your dose may be 30 to 120 mg daily. Your care provider may start you on a lower dose and gradually increase the amount as you progress through your treatment plan.
