MedlinePlus states that suddenly stopping Cymbalta can lead to withdrawal symptoms such as nausea, vomiting, diarrhea, anxiety, dizziness, tiredness, headache, pain, irritability, difficulty falling asleep or staying asleep, sweating, nightmares, and burning, numbness or tingling in the hands or feet. To prevent these symptoms from occurring, the dose of Cymbalta is usually gradually decreased. Cymbalta should only be stopped under a doctor's direction.
MedlinePlus reveals that Cymbalta is part of a class of medications called selective serotonin and norepinephrine reuptake inhibitors, or SNRIs. Cymbalta increases the amount of serotonin and norepinephrine in the brain, which helps maintain better mental balance and stops the movement of pain signals in the brain. Cymbalta is commonly used to treat depression, generalized anxiety disorder, and pain and tingling caused by diabetic neuropathy. It is also helpful in reducing pain caused by fibromyalgia and is sometimes used to treat chronic bone or muscle pain, such as lower back pain or osteoarthritis.
According to MedlinePlus, Cymbalta interacts with many other prescription and non-prescription medications and supplements, so it is crucial for a patient starting Cymbalta to inform his physician of all drugs he is taking. Coordination, thinking and judgment may be altered by taking Cymbalta, so driving or performing other activities that require alertness should be avoided until these effects are known.
