Cymbalta Ruined My Life–What it is and What You Should Know

- 11 sections

Medically Verified: May 15, 2025

All of the information on this page has been reviewed and verified by a certified addiction professional.

If you struggle with mental health, you are not alone. According to the National Institute on Mental Health (NIMH), “more than one in five U.S. adults live with a mental illness.”[1]

Two of the most common mental health conditions are major depressive disorder and generalized anxiety disorder. If you have one or both of these disorders, you might be prescribed a medication called Cymbalta (duloxetine).

Cymbalta is a serotonin-norepinephrine reuptake inhibitor (SNRI) that is mainly used to treat depression and anxiety.[2] Like any medication, it can cause side effects. Unfortunately, some people have found the side effects so severe that they say, “Cymbalta ruined my life.”

While Cymbalta is not addictive in the traditional sense, it can lead to physical dependence. This means you could experience withdrawal symptoms when you stop using it. Other adverse reactions to Cymbalta include sexual dysfunction, liver damage, high blood pressure, muscle pain, seizures, or serotonin syndrome.

Thankfully, it is possible to overcome the effects of Cymbalta. You can talk to your healthcare provider about tapering off the medication and finding an alternative method of treatment for your depression or anxiety disorder.

In this article, you will learn:

  • What is duloxetine?
  • What does Cymbalta treat?
  • Why do people say, “Cymbalta ruined my life?”
  • Does Cymbalta cause allergic reactions?
  • Can you get addicted to duloxetine?
  • What are the Cymbalta withdrawal symptoms?
  • What are the long-term effects of duloxetine?
  • How to recover from the effects of Cymbalta
  • What are the alternative medications to duloxetine?

What is Cymbalta?

Cymbalta is the brand name for duloxetine, a prescription medication that belongs to the serotonin-norepinephrine reuptake inhibitor (SNRI) class. These medications work by increasing serotonin and norepinephrine levels in the brain.

By increasing these neurotransmitters, Cymbalta can lessen anxiety symptoms and increase your happiness, making depression less severe.

If you receive Cymbalta, you’ll be given delayed-release capsules. They are only to be taken orally; you should swallow them whole. Breaking them into pieces can lessen their efficacy. The dose you are given will vary depending on how severe your symptoms are and what condition duloxetine is treating.

It is important to note that, like other antidepressants, Cymbalta carries a box warning about a potential risk for suicidal thoughts and behaviors in children, adolescents, and young adults.

What Does Cymbalta Treat?

Cymbalta increases the level of norepinephrine and serotonin in your brain. This makes it effective in managing a few different conditions.

The main conditions that Cymbalta can treat include:

  • Major Depressive Disorder (MDD) – Alleviates the symptoms of depression by increasing serotonin to cause happiness and lessening fatigue by affecting norepinephrine
  • Generalized Anxiety Disorder (GAD) – Reduces excessive worry and tension by increasing serotonin
  • Diabetic Peripheral Neuropathic Pain (DPNP) – Manages nerve pain caused by diabetic neuropathy.
  • Fibromyalgia – Eases muscle pain, stiffness, and fatigue by increasing norepinephrine.
  • Chronic Musculoskeletal Pain – Helps manage ongoing pain in muscles and bones.

If you have diabetic neuropathy, anxiety, muscle pain, or depression, a healthcare provider might prescribe Cymbalta. While taking Cymbalta can manage these conditions, it’s not effective for everyone. If you find yourself saying, “Cymbalta ruined my life,” it might be time to ask your healthcare provider to find you a new medication.

Why Do People Say “Cymbalta Ruined My Life?”

People say, “Cymbalta ruined my life” when they experience an array of adverse reactions from the medication. It’s a common phrase among people who have experienced severe withdrawal symptoms, ongoing side effects, or haven’t experienced benefits from the medication.

One of the common negative side effects associated with Cymbalta is emotional numbness, which can make it difficult for people to maintain close relationships with others. If duloxetine caused you to experience emotional numbness, you might come off as cold to your loved ones. This can lead to intense strains in relationships, making you feel as though Cymbalta ruined your life.

Even further, if you forget to take duloxetine, you might experience withdrawal symptoms. Examples of symptoms you might notice include brain zaps, flu-like symptoms, emotional instability, and chronic insomnia. Having these symptoms can lead you to begin believing the idea that “Cymbalta ruined my life.”

Lastly, duloxetine carries a black box warning, which is the most severe warning issued by the FDA. This warning states that Cymbalta can cause new or worsened suicidal thoughts.[3] This warning urges caregivers and loved ones to closely monitor the person consuming Cymbalta for any changes in mood, behavior, or the emergence of suicidal ideation during the initial months of treatment or following dose adjustments.

Can Cymbalta Cause Allergic Reactions?

Cymbalta can lead to allergic reactions, making it vital that you pay attention to your symptoms when you first begin taking it. The symptoms can range from mild to severe.

The mild allergy symptoms associated with Cymbalta include:

  • Itchiness
  • Mild skin rashes
  • Flushing of the skin
  • Swelling in the eyelids, lips, hands, or feet

Severe allergic reactions to Cymbalta include symptoms like:

  • Swelling of the mouth, tongue, or throat, leading to breathing issues
  • Severe skin reactions like Stevens-Johnson syndrome
  • Toxic epidermal necrolysis
  • Anaphylaxis, a life-threatening reaction

If you have these symptoms, consider discontinuing Cymbalta immediately. If your symptoms are severe, contact emergency medical services for assistance. If you develop breathing problems or anaphylaxis, you could die without medical intervention.

One of the severe side effects of Cymbalta is Stevens-Johnson syndrome.[4] This condition causes painful sores and rashes in the mouth, throat, eyes, and genitals. It can be life-threatening without medical assistance.

Is Cymbalta Addictive?

If a healthcare provider prescribes you Cymbalta, you might find yourself wondering whether it is addictive. Thankfully, duloxetine is not addictive in the traditional sense. It will not cause a mind-altering high, no matter what dose you consume.

That said, it can cause physical dependence. When you take any medication daily, your brain and body become dependent on it to function properly. If you suddenly stop consuming it, you will experience withdrawal symptoms.

Because sudden cessation of Cymbalta can cause withdrawal symptoms, you should contact your healthcare provider before you stop taking it. They will help you get on a tapering schedule that will prevent you from experiencing withdrawal.

Even though Cymbalta does not cause a high, some people might try to abuse it. You must avoid taking high doses of duloxetine, as this could lead to serotonin syndrome and a life-threatening overdose.

Cymbalta Withdrawal Symptoms

If you are taking Cymbalta, you should never stop it suddenly. Doing this can lead to the development of withdrawal. While Cymbalta is not addictive, the withdrawal symptoms associated with it can be intense.

The common withdrawal symptoms of Cymbalta include:

  • Brain Zaps- Often described as electrical sensations in the brain. Common among SNRIs and selective serotonin reuptake inhibitors (SSRIs).
  • Dizziness- You might experience dizziness or vertigo when standing up quickly, making daily tasks difficult.
  • Flu-Like Symptoms- You could have chills, muscle aches, and a fever during duloxetine withdrawal.
  • Emotional Instability- Because your body has lower levels of serotonin and norepinephrine than it’s used to, you might experience mood swings, irritability, anxiety, and severe depression.
  • Insomnia- Insomnia and vivid dreams are common withdrawal symptoms of Cymbalta. The lack of sleep can contribute to making your other symptoms more severe.
  • Fatigue- A lack of energy and extreme tiredness are common, making it difficult to complete daily activities.
  • High Blood Pressure- Because you are no longer managing your anxiety, your blood pressure could increase. This can be dangerous, especially if you already struggle with blood pressure issues.
  • Digestive Issues- It is common to experience withdrawal symptoms like nausea, vomiting, diarrhea, and appetite changes.

If you are experiencing withdrawal symptoms, you should ask a healthcare provider for help. They can provide you with a tapering schedule to get you off of duloxetine the healthy way. Tapering will minimize withdrawal symptoms and make it possible for you to continue with your daily life.

Adverse Effects of Cymbalta: Long-Term

If you find yourself saying, “Cymbalta ruined my life,” knowing the long-term effects of the medication can make it easier for you to understand what you are going through.

The most common long-term effects of Cymbalta include:[5,6,7,8,9]

  • Increased Risk of Falls- Among older adults, duloxetine is associated with an increased risk of falls and injuries.
  • Emotional Numbing- While Cymbalta is supposed to improve mental health disorders, sometimes it has an emotional numbing effect. Even though your depression or anxiety feels better, you might be unable to feel any emotion at all. This can make life lose its spark, causing you to be indifferent towards everything.
  • Sexual Dysfunction- Many medications for mental health disorders have this effect. You might experience difficulty getting aroused or a complete disinterest in sex altogether.
  • Weight Gain- Whether you are taking Cymbalta to treat fibromyalgia or a mental health condition, it can lead to significant weight gain over time. This is because the medication increases your appetite, causing you to eat more than usual.
  • Suicidal Behaviors- While you might be taking Cymbalta to treat depression, sometimes the medication makes it worse. You might experience new or worsening thoughts of suicide, which can be incredibly dangerous.
  • Cardiovascular Disease- Cymbalta has been linked to a few cardiovascular risks, like increased blood pressure, heart attacks, stroke, and more. If you are already experiencing cardiovascular issues, avoid taking duloxetine altogether.
  • Kidney Disease- If you are taking Cymbalta for nerve pain or another condition, long-term use can lead to worsened kidney disease.
  • Liver Damage- Cymbalta can cause physical health issues like liver damage when used long-term. For example, your liver has to work hard to process duloxetine, causing strain and damage over time.

While these effects can be severe, you should avoid stopping Cymbalta without talking to a doctor. The potential withdrawal symptoms (i.e., mood changes, panic attacks, severe nausea, trouble sleeping, worsening depression, chronic pain, and more) can be difficult to cope with, making it important that a medical professional helps you get on a tapering schedule to minimize withdrawal symptoms.

How to Recover From Cymbalta

While Cymbalta can lessen pain signals and improve pain response to treat chronic pain conditions and help manage depression or anxiety, it’s not right for everyone. Some people have a hard time when they are on duloxetine, dealing with intense side effects and severe withdrawal complications. If you feel like Cymbalta is ruining your life, it’s time to talk to a doctor about getting off of it.

Discontinuing Cymbalta requires gradual tapering. Your doctor will assess your symptoms, the dose of duloxetine you take, and how long you’ve been on the medication to decide what tapering schedule is right for you. It usually takes at least 4 weeks for you to completely taper off the medication.

If you believe you are still experiencing side effects of Cymbalta after you’ve tapered off, you might have post-acute withdrawal syndrome (PAWS). Thankfully, this condition can be treated using other medications, like antidepressants or mood stabilizers. Taking other medications can lessen the lingering side effects of Cymbalta and help you improve your mental health in the meantime.

In addition to tapering and treating PAWS, you should find other ways to manage your condition. If you were taking duloxetine to manage chronic joint and muscle pain, you should consider talking to a healthcare provider about finding a replacement medication or trying physical therapy. Physical therapy can be incredibly beneficial for managing chronic joint and muscle pain.

On the other hand, if you were taking Cymbalta for depression or anxiety, you need to find other ways to manage your symptoms. Talk to your healthcare provider immediately to determine what your next steps should be to manage your mental health.

If Cymbalta causes you to experience mood swings, there are ways you can improve mood effects once you are off the medication. For example, you could attend behavioral therapy to improve your mood regulation naturally. Additionally, regular exercise can reduce the frequency of mood swings because of the neurotransmitters released during physical activity.

Alternative Medications for Depression and Anxiety

If you were taking Cymbalta to manage depression and anxiety, only to receive adverse reactions, you might need to find a new medication. While therapy can manage these conditions, sometimes medication is necessary. If you are in the market for a new psychiatric med, it’s important to know your options.

Alternative medications that can treat depression and anxiety include:

  • Lexapro (escitalopram)- This medication is an SSRI and a good alternative for people who are worried about the long-term effects of Cymbalta, as it has fewer side effects associated with it.
  • Effexor (venlafaxine)- Effexor is an SNRI like Cymbalta; however, it is associated with fewer side effects. It can also manage depression, anxiety, and panic disorder.
  • Prozac (fluoxetine)- If you have depression and co-occurring OCD or bulimia, Prozac is a good option for you. It is an SSRI, which means it does not affect norepinephrine in the way that Cymbalta does.
  • Wellbutrin (bupropion)- Wellbutrin is not an SSRI or SNRI, which means it works in a completely different way than duloxetine. Instead, it increases dopamine and norepinephrine.
  • Pristiq (desvenlafaxine)- Pristiq is an SNRI similar to Cymbalta, however, the differences in its chemical structure make it less likely to cause the same long-term effects.
  • And More- If you experienced the common symptoms of Cymbalta and believe it ruined your life, there are other options out there. Your doctor can help you find an alternative medication that will not cause the same adverse reactions you experienced.
  •  

If your experience with Cymbalta has caused you to avoid medication, there are other ways to manage anxiety and depression. For example, you can attend individual and group therapy. These tools will help you learn emotional regulation skills, healthy coping mechanisms, and teach you how to rewire your thoughts into positive patterns.

Other natural ways to manage mood swings, anxiety, and depression include lifestyle changes like healthy eating, exercising, engaging in regular self-care routines, and spending time with loved ones or friends.

Alternative Medications for Pain Relief and Fibromyalgia

If you were taking Cymbalta to treat joint pain or fibromyalgia, there are other options to consider. While drug dependence is likely with any medication, you won’t have to worry about long-term effects like emotional numbness or black box warnings for suicidal thoughts.

Options for fibromyalgia after trying Cymbalta include:

  • Pregabalin (Lyrica)- This medication is considered an anticonvulsant, however, it can help reduce pain and improve sleep among people with fibromyalgia.
  • Milnacipran (Savella)- Savella is an SNRI like Cymbalta. That said, you might not experience the same adverse reactions when taking this medication. It can help with pain, fatigue, and other symptoms of fibromyalgia.
  • Gabapentin (Gralise, Horizant)- This medication is an anticonvulsant as well. It can reduce pain associated with fibromyalgia. If you have co-occurring anxiety, gabapentin can be used off-label to reduce stress.
  • Other SSRIs- Many SSRI medications can improve symptoms associated with fibromyalgia, like pain, sleep, fatigue, and mood.

If weight gain was your main concern when taking Cymbalta, it’s important to note that this is a common symptom among many medications. Unfortunately, most medications for fibromyalgia will not produce weight loss effects. That said, you can offset weight gain with mindful eating habits and regular exercise.

Lastly, if your experience with Cymbalta turned you off from taking medication, there are some natural ways to cope with the condition. While natural remedies might not be enough for everyone, it’s worth a shot. You could try a combination of regular exercise, healthy eating, and cognitive-behavioral therapy (CBT) to manage your symptoms.
