Cymbalta vs. Celexa
See how Cymbalta and Celexa compare on approved uses, dosing, side effects, and cost.
Key Takeaways
Cymbalta is an SNRI approved for depression, anxiety, and several chronic pain conditions, while Celexa is an SSRI approved only for major depressive disorder in adults.
Both carry a boxed warning for increased suicidal thinking in young people, but Celexa also carries a dose-dependent QT prolongation warning that Cymbalta's label does not include.
Cymbalta's pain indications and twice-daily option make it useful beyond mood disorders, while Celexa's simple once-daily dosing suits straightforward depression treatment.
Cymbalta vs. Celexa Drug Summary
Cymbalta
Cymbalta (duloxetine) is a serotonin and norepinephrine reuptake inhibitor (SNRI) approved for depression, generalized anxiety, and chronic pain conditions like diabetic neuropathy and fibromyalgia. It is taken as a delayed-release capsule, typically once daily, with some patients splitting the dose twice a day at higher strengths.
Celexa
Celexa (citalopram) is a selective serotonin reuptake inhibitor (SSRI) approved for major depressive disorder in adults. It is taken as a once-daily tablet or oral solution, and clinicians also prescribe it off-label for anxiety and panic disorders despite lacking FDA approval for those uses.

Cymbalta vs. Celexa Indications
Cymbalta
Cymbalta treats major depressive disorder and generalized anxiety disorder, and it is also FDA-approved for several chronic pain conditions. This makes it a common choice when depression or anxiety occurs alongside diabetic nerve pain, fibromyalgia, or musculoskeletal pain.
Major depressive disorder
Generalized anxiety disorder
Diabetic peripheral neuropathic pain
Fibromyalgia
Celexa
Celexa is FDA-approved only for major depressive disorder in adults. It is frequently prescribed off-label for anxiety-related conditions, though those uses are not supported by an FDA label indication.
Major depressive disorder in adults
Generalized anxiety disorder (off-label)
Panic disorder (off-label)
Obsessive-compulsive disorder (off-label)
Cymbalta vs. Celexa Pros and Cons
Cymbalta
Cymbalta's SNRI action extends its use beyond depression into chronic pain management, giving it broader clinical utility than many antidepressants. It requires caution in patients with liver or significant kidney disease, and its side effect profile differs somewhat from standard SSRIs.
Pros
Approved for chronic pain conditions like diabetic neuropathy and fibromyalgia, not just mood disorders
Acts on both serotonin and norepinephrine, which can help pain and mood symptoms together
No QT prolongation warning on its label, unlike Celexa
Cons
Must be avoided in patients with chronic liver disease or severe kidney impairment
Higher rate of nausea reported than Celexa (up to 30% vs 21%)
Discontinuation symptoms can be more pronounced due to its dual-action mechanism
Celexa
Celexa is a long-established SSRI with decades of safety data and predictable once-daily dosing for adults with depression. Its main limitations are a dose ceiling tied to QT prolongation risk and lack of FDA approval for anxiety disorders that are often treated off-label.
Pros
Decades of established safety data as one of the most widely prescribed SSRIs
Simpler once-daily dosing without a twice-daily maintenance option to manage
Available in tablet and oral solution forms for patients who have trouble swallowing pills
Cons
Dose-dependent QT prolongation risk that limits doses above 40 mg per day
Not FDA-approved for anxiety, panic, or OCD despite common off-label use
Maximum dose capped at 20 mg for elderly patients, hepatic impairment, or poor metabolizers
