Cymbalta (duloxetine) is an antidepressant and antianxiety medication that is also used to treat diabetic neuropathy and fibromyalgia. It belongs to the class of drugs known as serotonin and norepinephrine reuptake inhibitors (SNRIs). SNRIs have a profound effect on the brain, increasing the activity of norepinephrine and serotonin neurotransmitters. Some people develop withdrawal symptoms when they stop taking SNRIs.
When you stop taking Cymbalta, your brain may take some time to acclimate to being without it. You may have flu-like symptoms and dizziness during this period. In the days and weeks after your last dose of Cymbalta, you may have headaches, vomiting, and nausea. Nightmares or unsettling dreams, as well as pins and needles sensations that appear and disappear throughout the body, are more upsetting symptoms.
Withdrawal can be mild, severe, or prolonged. Discuss this risk before reducing or stopping treatment; the term “antidepressant discontinuation syndrome” also refers to withdrawal symptoms.
According to a pooled study of six distinct placebo-controlled research trials, 44.3 percent of patients who stopped taking duloxetine (Cymbalta) experienced withdrawal-like symptoms, as opposed to 22.9 percent of those who took the placebo. Dizziness was the most prevalent symptom, second by headache and nausea.
The majority of individuals in the duloxetine (Cymbalta) studies described their complaints either as mild or moderate. Around 65 percent of those reporting withdrawal symptoms indicated their problems went away in roughly a week.
Since SNRIs like duloxetine do not produce a euphoric “high” like other prescription medications, they are not commonly abused.
Taking more duloxetine than prescribed is misuse and can cause harm. Cymbalta is a delayed-release capsule: swallow it whole and do not crush, chew, open it, or mix its contents into a drink.
The following behaviors or symptoms warrant clinical review. Symptoms alone do not establish misuse; they may reflect side effects, withdrawal, or another condition:
- Increasing the dose without seeking medical advice
- As a result of ingesting duloxetine, you may experience drowsiness or pass out.
- Vomiting
- Blood pressure fluctuations
- Bloodshot eyes
- Slurring of speech
- Changes in physical looks that happen unexpectedly
- Changes in sleep habits that are noticeable
Seizures require emergency help. Suicidal thoughts need urgent assessment; call local emergency services if there is immediate danger or you cannot stay safe. Depression or taking more than one antidepressant does not by itself establish misuse; medication combinations require prescriber review for interactions.
The body adapts to duloxetine, and symptoms can occur when a dose is reduced or stopped. Their timing and duration vary. Tell your prescriber about new symptoms so they can assess withdrawal, side effects, or a return of the treated condition.
It’s important to keep in mind that any physical reliance you may have acquired is not your fault and is not something to be embarrassed about. Your mental and physical health is far more essential than any guilt or shame you may feel about revealing you’re experiencing duloxetine withdrawal symptoms. Your physicians want the ideal for you, therefore they will do everything they can to assist you in overcoming your dependency.
You may have a variety of symptoms throughout this time, such as:
- Dizziness
- Headaches and lightheadedness
- Nausea
- Needles and pins
- Vomiting
- Nightmares
- Anxiety
- Unusual sensations such as buzzes in the head
- Sleeping problems
- Irritability
Symptoms may begin within days of a reduction or missed doses, but timing and duration vary. Gradual reduction lowers the risk and can still be accompanied by withdrawal symptoms.
Duloxetine can cause severe or prolonged withdrawal symptoms. These should not be dismissed as effects specific to another antidepressant.
Some of the widespread and severe symptoms from duloxetine withdrawal constitute a syndrome called Cymbalta Discontinuation Syndrome, which is a well-known issue. As mentioned, according to a 2005 study on generic duloxetine, 44 percent of participants had withdrawal symptoms. Eli Lilly paid lawsuits in 2016 from patients who claimed that the seriousness of the withdrawal symptoms was misrepresented to them.
Severe or unexpected symptoms need clinical assessment; a seizure requires emergency care. Do not alter Cymbalta delayed-release capsules or combine their contents with a drink.
One record of a withdrawal seizure and one account of withdrawal symptoms that came and went over a ten-month period have been reported in research studies on Cymbalta withdrawal.
It’s also important to remember that because duloxetine is an antidepressant, any abrupt dosage adjustments might cause severe psychological withdrawal symptoms. Rebound anxiety, worsening depression, sleeplessness, and suicidal ideation are examples. Because of the severity of these possible withdrawal symptoms, it’s usually advisable to go off duloxetine gradually under the guidance of a medical practitioner.
There is no average withdrawal timetable that applies to everyone. Symptoms often begin within the first few days after a reduction or missed doses, but their duration varies. Many resolve within a shorter period, while some people experience symptoms for weeks or months. Treatment should be adjusted according to the individual response rather than a fixed detox calendar.
The Initial Signs
Withdrawal symptoms can begin after a dose reduction, an abrupt stop or sometimes missed doses, but they do not reliably start at 12 hours and severity cannot be predicted from a simple half-life calculation. The timing varies with dose, duration, formulation, metabolism and individual sensitivity.
24 Hours Later
Symptoms such as nausea, agitation, and sweating may follow a dose reduction or missed doses, but timing varies and is not fixed at 24 hours.
The Following Weeks
Symptoms and their duration vary considerably. A return of the original depression or anxiety can also occur, and it may be difficult to distinguish relapse from withdrawal without looking at timing, symptom pattern and clinical history. Suicidal thoughts require prompt assessment regardless of whether they are thought to reflect withdrawal, relapse or another cause.
There Is No Such Thing As A Universal Timeline
The severity of Cymbalta withdrawal and the time it takes to cease experiencing symptoms are determined by the individual characteristics of each patient. It’s hard to predict how each person will react to the withdrawal of duloxetine. As a result, medical monitoring is urgently recommended to assist the patient in quitting duloxetine without causing harm to their health.
Duloxetine withdrawal requires medical assistance and supervision. Many people assume they can wean themselves off of antidepressants. Stopping any antidepressant, unfortunately, carries the risk of health consequences. There are also chances of consequences if a person switches drugs without medical supervision. It can also apply when a patient ceases using duloxetine in conjunction with other medications, like Cymbalta and Wellbutrin.
Duloxetine should generally not be stopped abruptly. Withdrawal symptoms are more common after sudden discontinuation, so the prescribing information recommends a gradual reduction when treatment is no longer needed. The pace should be adjusted to the person’s dose, treatment duration, symptoms and clinical situation rather than treating “cold turkey” and tapering as equivalent options.
Quitting Cold Turkey
Knowing how risky it is to discontinue Cymbalta cold turkey, it may seem strange that people would explore this option. This is not always through choice, though. There’s a chance that if someone loses their insurance or can’t afford the next month’s drugs, they won’t have another alternative.
Sudden discontinuation can cause dizziness, sensory disturbances, sleep problems, anxiety or agitation, nausea, headache and other withdrawal symptoms. Some people experience severe or prolonged symptoms. New suicidal thoughts, severe agitation, marked confusion, a seizure or an inability to stay safe requires urgent clinical assessment rather than being assumed to be a routine withdrawal effect.
If someone feels they have no option but to go cold turkey, they should speak with their doctor to see if there is anything they can do to assist them to quit taking it safely.
Tapering Off
The safest way to discontinue taking Cymbalta is to taper off the medication, often known as weaning off the pill. It should, however, be performed under medical supervision. There are appropriate and inappropriate ways to taper, and adhering to the patient’s specific taper timetable is crucial to success. It takes a few weeks for some patients to taper down, while it takes months for others.
The following principles can guide a taper planned with the prescriber:
- There is no universal sequence of 90, 60, 30, 20 and 10 mg that is appropriate for every patient.
- The prescribing information recommends gradual dose reduction, while the exact steps depend on the dose, formulation, duration of treatment and response to each reduction.
- If withdrawal symptoms become difficult to tolerate, the prescriber may pause the reduction or return temporarily to the previous dose before reducing more gradually.
Every taper should be individualized with the prescriber and adjusted to symptoms and clinical needs; there is no standard schedule for all patients.
Reduce Cymbalta gradually with your prescriber, adjusting the pace to symptoms. A fixed 2-to-4-week taper is not suitable for everyone, and gradual reduction cannot guarantee that withdrawal symptoms will be avoided.
Cymbalta is a drug that acts in the brain to alleviate anxiety and depression. It works by boosting norepinephrine and serotonin levels in the brain. It may take many weeks for your body to adapt to function normally without the medicine once you stop using it. You may encounter side effects that are uncomfortable at this time. The most prevalent withdrawal adverse effect of Cymbalta has been shown to be dizziness, which affects over 12 percent of patients.
Slowly stopping treatment may not be enough to avoid all withdrawal symptoms. Even after a slow taper as suggested by your doctor, if you are still having withdrawal symptoms, seek medical advice again. They might opt to slow things down even more.
You and your doctors may decide to switch your therapy to another prescription in addition to a gradual withdrawal.
- There are numerous alternatives for treating anxiety and depression, as well as other applications for this medication.
- When quitting treatment, you may wish to talk to a therapist or seek counseling (talk therapy) to help you manage anxiety, mood swings, and other issues.
- Inform your friends and family that you will be gradually discontinuing treatment over many weeks or months, so they are aware that you may experience side effects.
- To keep your body strong and prepare yourself, eat properly, get plenty of sleep, exercise, and talk to your doctor as soon as your depression symptoms return.
Duloxetine has an average elimination half-life of about 12 hours, with individual variation. This does not predict when withdrawal begins or ends, or establish when pregnancy is safe.
Drug-test detection and clinical recovery are different questions:
- Blood. Blood concentrations depend on timing, metabolism, and the test used; they do not set a withdrawal or conception timetable.
- Urine. Urine testing does not establish recovery from withdrawal or reproductive safety.
- Saliva. There is no universal saliva-detection window that can guide when to conceive.
- Hair. Hair testing cannot determine whether a medicine remains active or whether pregnancy is safe.
If you are planning pregnancy or become pregnant, discuss duloxetine with your prescriber. It may be appropriate after weighing medication risks against the risks of untreated illness or relapse. Do not stop abruptly or use a drug-test detection window to decide when to conceive.
