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.

Conditions Cymbalta Treats

Cymbalta is FDA-approved to treat major depressive disorder and anxiety disorder. It can also be prescribed for other conditions in an off-label capacity. 

Cymbalta Can Treat Symptoms of Anxiety and Depression

Cymbalta is an antidepressant that treats symptoms of anxiety and depression, including the following.

For depression:

  • Feeling sad or hopeless
  • Loss of interest in favorite activities
  • Sleeping or eating more or less than usual
  • Difficulty concentrating
  • Suicidal ideation

For anxiety disorders:

  • Restlessness
  • Fatigue
  • Difficulty concentrating
  • Irritability
  • Muscle tension
  • Sleep disturbances

Off-Label Uses for Cymbalta

Beyond treating major depression and anxiety disorder, Cymbalta can also be prescribed off-label to treat nerve pain associated with diabetes. Off-label use of medications means that while it may not be FDA-approved to treat nerve pain, it has been an effective treatment if other medicines fail.

Licensed providers on Klarity provide personalized treatment. Find a provider that matches your needs and preferences.

Cymbalta Costs

The cost of Cymbalta varies based on your prescribed dose, the pharmacy you use, and your insurance coverage. You can expect to pay anywhere from $3.99 to $50.87 for 30 capsules of 30 mg.
