These insights are based on 1,279 comments about Cymbalta from MyDepressionTeam members. These are the experiences of a small number of individuals and are not meant to be medical advice.
Cymbalta is an antidepressant that works by increasing serotonin and norepinephrine activity in the central nervous system, which includes the brain and spinal cord. The exact way it works is not fully known.
Doctors prescribe Cymbalta for adults with major depressive disorder. By affecting the brain chemicals serotonin and norepinephrine, Cymbalta may help improve depression symptoms.
Cymbalta is given as a delayed-release capsule by mouth, typically once daily or twice daily. Some people start with a lower daily schedule for the first week before moving to the usual daily schedule. Cymbalta capsules should be swallowed whole.
Don’t crush, chew, or open the capsule, and do not sprinkle the contents on food or mix them with liquids.
The recommended starting dose of Cymbalta for major depressive disorder is 40 milligrams per day, given as 20 milligrams twice daily, to 60 milligrams per day, given either once daily or as 30 milligrams twice daily.
For people who respond to treatment, the recommended maintenance dose is 60 milligrams per day, given once daily or as 30 milligrams twice daily.
For some people, a doctor may start treatment at 30 milligrams once daily for one week before increasing to 60 milligrams once daily. The maximum dose is 120 milligrams per day. When stopping treatment, doctors usually recommend lowering the dose gradually instead of stopping suddenly.
This information is based on the prescribing information, but your healthcare provider may tailor your treatment plan. Always follow their guidance.
Members who use Cymbalta often say the most helpful approach is to stay in close contact with your doctor, especially when side effects, dose changes, or medication switches come up. Many members also say it helps to expect some trial and error, pay attention to how your body responds, and avoid stopping Cymbalta suddenly.
Give it some time, but keep track of how it’s working.
“I’ve been on Cymbalta for nine months, and after about three weeks, I started to feel better, more energized.”
Talk to your doctor before changing or stopping Cymbalta.
“My doctor said it’s dangerous to just stop taking it. You have to be weaned off of it.”
Keep your healthcare provider updated about side effects and dose changes.
“My PA doubled it, and now I feel better. My pain is almost zilch. It’s for chronic depression, anxiety, and pain as well.”
Pay attention to side effects that affect daily life.
“It has suppressed my appetite a great deal.”

In adult clinical trials for major depressive disorder and generalized anxiety disorder, some side effects were reported more often with Cymbalta than with placebo (an inactive treatment).
These side effects occurred in about 6 percent to 23 percent of people taking Cymbalta:
Cymbalta can cause serious side effects that require immediate medical attention. These include:
Get medical help right away if you think you are having a serious reaction.
Talk with your healthcare provider, pharmacist, or insurance plan about ways to reduce the cost of Cymbalta. They may be able to help you compare coverage, generic options, or pharmacy pricing.
You can also check the manufacturer’s website and your health plan’s prescription benefits for current savings information and coverage details.
Tell your doctor if you have any allergies to duloxetine or any ingredients in Cymbalta.
Tell your doctor about all medicines you take, including prescription drugs, over-the-counter medicines, and supplements.
Do not take Cymbalta if you take a monoamine oxidase inhibitor (MAOI), including linezolid or intravenous methylene blue. Do not take an MAOI within five days of stopping Cymbalta, and do not start Cymbalta within 14 days of stopping an MAOI.
Tell your doctor if you drink a lot of alcohol, have liver disease, have kidney problems, have diabetes, or have a condition that slows stomach emptying. Cymbalta may not be right for people with heavy alcohol use, chronic liver disease, or severe kidney problems. Your doctor may check your blood pressure before and during treatment.
Cymbalta is also FDA approved to treat generalized anxiety disorder, diabetic peripheral neuropathic pain, fibromyalgia, and chronic musculoskeletal pain.
If you miss a dose, take it as soon as you remember. If it is almost time for your next dose, skip the missed dose. Do not take two doses at the same time.
If you are pregnant, planning to become pregnant, or breastfeeding, talk with your doctor about the risks and benefits. Taking Cymbalta near delivery may raise the risk of heavy bleeding after childbirth. Babies exposed late in pregnancy may have breathing trouble, feeding problems, shaking, irritability, or other symptoms after birth.
Cymbalta can pass into breast milk, so breastfed babies should be watched for sleepiness, poor feeding, or poor weight gain.

How effective is Cymbalta for major depressive disorder?
In four short-term studies in adults with major depressive disorder, Cymbalta was better than placebo at improving depression symptoms based on changes in the 17-item Hamilton Depression Rating Scale, a standard measure of depression severity. In a maintenance study, people taking Cymbalta had a statistically significantly longer time between relapses of depression than people taking placebo.
How long does Cymbalta take to work for major depressive disorder?
In adult studies of major depressive disorder, improvement in depression symptoms was measured at the end of short-term studies. The earliest documented endpoint was eight weeks. In those eight-week studies, people taking Cymbalta had greater improvement in depression scores than people taking placebo.
Other short-term studies measured improvement at nine weeks.
Can Cymbalta cause sweating with major depressive disorder?
Yes. Increased sweating, called hyperhidrosis, was one of the most common side effects in adults, occurring in 6 percent of people taking Cymbalta compared with 1 percent taking placebo. Sweating is also listed among the most common side effects in the Medication Guide.
