Cymbalta® side effects include nausea, dry mouth, sleepiness, fatigue, constipation, dizziness, decreased appetite, and increased sweating. Cymbalta® raises levels of the neurotransmitters serotonin and norepinephrine in the brain. Studies have shown that in rare cases, youths up 24 years of age may develop suicidal tendencies while taking Cymbalta®.[1]

Cymbalta® is a prescription medication used to combat depression and Generalized Anxiety Disorder (GAD) - a condition characterized by excessive worry and tension that can interfere with everyday activities and lasts for half a year or more. Cymbalta® also treats pain and tingling caused by diabetic nerve damage and fibromyalgia. In addition, the drug is used to treat ongoing bone or muscle pain like lower back pain or osteoarthritis.[1]

About Drug Side Effects

Details about side effects from prescription drugs like Cymbalta

Cymbalta Allergic Reactions

Cymbalta® can cause a form of Erythema multiforme called Stevens-Johnson syndrome, which is characterized by fever, itching of the skin, joint pain, and multiple skin lesions. The lesions may resemble hives, but may also appear as nodules or a sore surrounded by bulls-eye rings. Stevens-Johnson syndrome can be fatal.[5] [6] Other patients may develop Cymbalta® allergic symptoms such as skin rash, blisters, or sores inside the mouth.[7]

Cymbalta Withdrawal

Some patients have experienced side effects after discontinuing Cymbalta®. These withdrawal symptoms included mood changes, dizziness, nausea, headache, exhaustion, nerve pain, confusion, vomiting, nightmares, insomnia, diarrhea, anxiety, excessive sweating, vertigo, tinnitus, and seizures.[8] To minimize SSRI withdrawal symptoms, Cymbalta® is generally discontinued gradually, with a physician tapering down the dosage over a period of several weeks.[9] Some physicians will switch the patient from Cymbalta® to Prozac before beginning the taper, as Prozac has a longer half-life, making the effect on the brain more gradual.[10]
