Slowly stopping Cymbalta treatment over 2 to 4 weeks is the best way to help avoid withdrawal symptoms like dizziness, nausea or headache. Talk with your doctor first if you want to stop treatment. It is best not to abruptly discontinue Cymbalta (duloxetine).
Cymbalta works in the brain to treat conditions like depression and anxiety. It works by increasing brain chemicals such as serotonin and norepinephrine. When you stop treatment, it can take several weeks for your body to adjust to being without the medicine. During this time, you may experience side effects that can be bothersome (see a list below). Dizziness has been shown to be most common withdrawal side effect with Cymbalta, occurring in over 12% of people.
Slowly discontinuing treatment may not prevent all withdrawal side effects. Contact your healthcare provider again if you are still experiencing withdrawal symptoms, even with a gradual taper as directed by your doctor. They may decide to stop it even more slowly.
How long does Cymbalta withdrawal last?
In studies, most withdrawal side effects (65%) resolved within 7 days of stopping treatment. Nearly all patients rated these side effects as mild-to-moderate in severity.
More patients using the highest 120 mg per day dose of Cymbalta (the maximum prescribed dose for depression or anxiety) reported side effects, but most people do not use a dose this high because it does not add any benefit.
What are the withdrawal symptoms with Cymbalta?
A large review of 6 studies evaluated withdrawal symptoms with duloxetine (Cymbalta) doses ranging from 40 to 120 mg per day for 8 to 9 weeks. The study included 870 patients with a diagnosis of depression, and Cymbalta compared to a placebo (an inactive capsule).
Researchers found that when the medicine was abruptly stopped, withdrawal symptoms occurred in 44% of duloxetine patients compared to 23% of those taking the placebo, a significant difference.
- dizziness (12.4%)
- nausea (5.9%)
- headache (5.3%)
- “pin-and-needles” or burning feeling on skin, called paresthesia (2.9%)
- vomiting (2.4%)
- irritability (2.4%)
- nightmares (2%).
Other withdrawal (discontinuation syndrome) symptoms reported by the manufacturer (in 1% of patients or greater) are: diarrhea, insomnia, anxiety, hyperhidrosis (excessive sweating), and fatigue.
In the period after Cymbalta was approved, the manufacturer has also had reports of confusion, lethargy, emotional lability, hypomania (mild overactive behavior), tinnitus (ringing or noises in the ears), and seizures.
One case report described a seizure occurring a 59 year old woman who abruptly stopped treatment. The author noted the seizure may have been aggravated by low electrolyte levels in the blood. If you have a history of seizures, be sure to tell your doctor before you start treatment.
