Does Cymbalta cause withdrawal symptoms?
It is common for individuals to experience withdrawal symptoms when stopping an antidepressant medication, such as Cymbalta (duloxetine). The risk of withdrawal symptoms occurring is increased if the medication is stopped abruptly, so gradual dose reduction is recommended.
The risk and severity of withdrawal symptoms are often related to the half-life of the medication. The half-life refers to how long it takes for the medication to be excreted from the body. Medications with a shorter half-life tend to be more likely to cause withdrawal symptoms, as the effects of the medication stop in a shorter time.
Cymbalta (duloxetine) has a short half-life of 12 hours, meaning that half of the medication is excreted in 12 hours and almost all of the medication has left the body in 2-3 days. Because of this, it is likely to cause withdrawal symptoms, particularly with abrupt stoppage or rapid dosage reduction.
Cymbalta (duloxetine) works by impacting the levels of serotonin and norepinephrine, which are responsible for several functions within the brain and body. With prolonged use, the function of these neurotransmitters is altered significantly. As such, when the medication is stopped, the body must adjust to the lack of the medication, which can cause several physical and emotional effects.
Cymbalta withdrawal symptoms
When stopping antidepressant medication, it is common to experience some withdrawal symptoms, especially if the medication is stopped suddenly. Typically, these symptoms will be mild and will resolve within two to three weeks.
Changes in appetite
Electric shock sensations in the brain and body
Vivid dreams or nightmares
In some cases, withdrawal symptoms can be more severe or long-lasting. When stopping Cymbalta (duloxetine), if withdrawal symptoms occur that severely impact daily functioning or last longer than a month, contact the prescribing doctor for advice.
Severely depressed mood
Extreme mood changes
New or worsening suicidal ideation
Persistent or severe pain or headaches
Dizziness that leads to falls or fainting
Persistent vomiting or diarrhea
Cymbalta withdrawal timeline
When stopping Cymbalta (duloxetine), it is common for withdrawal symptoms to begin within 1-4 days. If the medication is reduced gradually, it may take longer for withdrawal symptoms to emerge, if at all.
Withdrawal symptoms, such as flu-like symptoms, shaking, nausea, and dizziness, are likely to be at their most severe within the first two weeks. After this, these symptoms are likely to be alleviated, leaving no residual withdrawal symptoms.
However, for some people, withdrawal symptoms do not improve after two to three weeks and may continue for several months or even years. It is not known why some people experience very severe and persistent withdrawal symptoms, although it may be linked to the treatment duration and dosage.
Cymbalta cessation timeline
A safe reduction in the dosage of Cymbalta (duloxetine) will likely vary from person to person. Some people may experience severe withdrawal symptoms and require a very slow and minimal dosage reduction, while others could experience little or no withdrawal symptoms and manage larger and faster dose reductions.
It is advised to taper off Cymbalta (duloxetine) gradually over several weeks at a minimum. Some people may need to continue this process over several months. Cessation timelines could involve a dosage reduction of between 5-50% every two to four weeks.
Typically, a daily dose of Cymbalta (duloxetine) is around 60mg. A cessation timeline for this dosage could include:
Week 1 and 2: 50% reduction of the original dose at 30mg per day
Week 3 and 4: 50% reduction of the previous dose at 15mg per day
Week 5 and 6: 50% reduction of the previous dose at 7.5mg per day
Week 7 and 8: Complete cessation if appropriate or a further 50% reduction in dosage
If a 50% reduction of the initial dose causes severe withdrawal symptoms, making smaller and more gradual reductions may be necessary. For example, this could involve a 5mg reduction every four weeks, allowing time for withdrawal symptoms to reduce before the next dosage change.
The prescribing doctor will closely monitor for any physical or mental health changes throughout this process. It is important to report withdrawal symptoms to the prescribing doctor to ensure safe cessation with minimal risks.
Cymbalta detox treatment
When stopping Cymbalta (duloxetine), your doctor will ask about your physical and mental well-being to monitor for any withdrawal symptoms. If you experience severe withdrawal symptoms, they may choose to:
Increase the dose of your medication
Pause cessation or wait longer before further reducing your dose
Introduce a different medication with a longer half-life, such as fluoxetine
Continue with cessation and advise you with managing your symptoms
During this time, you may find it helpful to utilize various self-care techniques, which can help to reduce the impact of withdrawal symptoms. This could include:
Planning: It can be helpful to learn more about the medication and potential withdrawal symptoms that you may experience. This can make it easier to plan for the cessation process, reduce concerns about symptoms that may occur, and provide information to loved ones so that they can provide appropriate support.
Healthy lifestyle choices: Adopting healthy habits can help to improve mental and physical well-being and reduce the impact of withdrawal symptoms. This can include eating a healthy diet, exercising regularly, avoiding alcohol and drugs, and getting plenty of sleep.
Talking to others: Utilizing a support system can help to manage emotional distress that may occur as a result of withdrawal symptoms or underlying mental health conditions. This could include speaking with friends and family, seeking professional help, or attending a support group.
Calming activities: Utilizing calming and relaxation activities can help to reduce the physical and emotional impact of withdrawal symptoms. This could include breathing exercises, meditation, yoga, reading, walking, and listening to music.
