What is Cymbalta?

Cymbalta Review

Cymbalta is a medication that contains the active ingredient duloxetine, which belongs to the class of drugs called serotonin-norepinephrine reuptake inhibitors (SNRIs). This medication is used to treat various conditions, such as major depressive disorder, generalized anxiety disorder, diabetic peripheral neuropathic pain, fibromyalgia, and chronic musculoskeletal pain.

Cymbalta is manufactured by Eli Lilly and Company, a global pharmaceutical leader founded in 1876. Eli Lilly has a long history of developing innovative medicines to address significant unmet medical needs and improve the quality of life for patients across the globe.

The development of Cymbalta began in the late 1990s, with the aim to create a new antidepressant that could address some shortcomings of the selective serotonin reuptake inhibitors (SSRIs). The hope was that by targeting both serotonin and norepinephrine, this new drug could provide better efficacy and fewer side effects.

Eli Lilly successfully developed duloxetine, which was later given the brand name Cymbalta. The US Food and Drug Administration (FDA) first approved Cymbalta in 2004 for the treatment of major depressive disorder.

How Does It Works?

Cymbalta works by increasing the levels of serotonin and norepinephrine in your brain. These neurotransmitters help regulate mood, pain, and other important aspects of both mental and physical well-being. By targeting both of these neurotransmitters, Cymbalta is able to provide a more balanced approach to treating various conditions.

When taking Cymbalta, it’s essential to follow your healthcare provider’s instructions and be patient, as it may take several weeks for the medication to fully take effect. It’s also important to keep your doctor informed of any side effects or concerns, so they can monitor your progress and make any necessary adjustments to your treatment.


Cymbalta, also known as duloxetine, is a medication prescribed for various conditions such as depression, anxiety, and pain management. In this section, you will learn about the key active ingredient in Cymbalta as well as some of the inactive ingredients that aid in the medication’s effectiveness and stability.
