People who struggle with general or social anxiety or prolonged depression may be able to control their symptoms by using a medication called Cymbalta. Cymbalta is a prescription medication that contains duloxetine, a type of selective serotonin and norepinephrine reuptake inhibitor. This medication helps balance a patient's brain levels of two mood-balancing chemicals: serotonin and norepinephrine. Patients should take Cymbalta as prescribed by a medical professional. Patients who abruptly stop taking Cymbalta may experience unpleasant medical side effects associated with withdrawal.
Headache or Dizziness
Patients who suddenly stop taking this medication may experience headache or dizziness as side effects of withdrawal, PubMed Health warns. Uncomfortable headache pain can make it difficult for patients to remain alert or focused during normal daily work, school, home or social activities. Sensations of dizziness could exacerbate headache pain and might cause patients to appear disoriented, confused or unstable while attempting to move about normally.
Sleeping Problems
Sleeping problems may arise in patients who are not properly weaned off of Cymbalta treatment, according to the U.S. Food and Drug Administration. Affected patients may experience insomnia, which causes difficulty falling asleep and staying asleep through the night. Certain patients may also experience bizarre or unpleasant nightmares, a side effect that could worsen insomnia.
Upset Stomach
Abruptly ending treatment with Cymbalta can cause upset stomach side effects in patients. According to RxList.com, these gastrointestinal complications include nausea, vomiting or diarrhea. Patients who experience diarrhea may also experience abdominal cramping, pain or bloating.
Unusual Body Sensations
Patients who suddenly stop taking this medication may develop unusual sensations throughout the body. The hands or feet may feel abnormally tingly or numb, which could be uncomfortable.
Sweating
Excessive sweating, or hyperhidrosis, could occur in patients who end treatment with Cymbalta without first consulting a doctor. Increased perspiration may cause a patient's skin to appear moist or flushed and cool or clammy to the touch. This side effect could also interfere with a patient's ability to sleep soundly through the night.
Irritability or Anxiety
Abruptly ending treatment with Cymbalta can cause mood-related side effects, including increased irritability or anxiety, PubMed Health warns. These mood changes may have a negative impact on a patient's daily interactions with family members, friends or colleagues. Patients who experience severe, sudden mood changes should receive further evaluation and care from a medical professional.
