Does Cymbalta-induced brain fog go away? (3+ facts)

In this article, we will answer if Cymbalta-induced brain fog goes away. We will also include some research findings to support our discussion, along with tips to manage Cymbalta-induced brain fog.

Does Cymbalta-induced brain fog go away?

Yes, Cymbalta-induced brain fog goes away as your body gets used to the medication. The side effects caused by Cymbalta vary from person to person, and not every individual experiences them. 

Cymbalta acts by increasing the neurotransmitters such as serotonin, norepinephrine and dopamine and these neurotransmitters play an important role in mood, perception, memory, attention, sleep and concentration. An increase in these neurotransmitters helps treat the symptoms of depression and anxiety. (1)

Cymbalta is a serotonin-norepinephrine reuptake inhibitor (SNRI) which is used to treat depression, anxiety disorders, fibromyalgia, chronic musculoskeletal pain and diabetic peripheral neuropathy. (2)

Some individuals experience brain fog at the beginning of the treatment, which is common and usually subsides as they get used to the medication or can be managed by decreasing the dose of the drug. If you are experiencing brain fog, make sure you consult your physician for proper management and avoid abrupt discontinuation of the drug. 

What does the research suggest? 

Antidepressants improve cognitive functions such as memory, mood, attention, concentration, etc. Some individuals respond to antidepressants and show improvement in their depressive symptoms, while some individuals are non-responders and they show either no improvement or a decline in cognitive functioning. (3)

Research studies have reported that long-term treatment with antidepressants is associated with an increased risk of mild cognitive impairment. (4)

In a clinical study, it was observed that elderly patients aged 75 or above who had a poor response to antidepressants experienced a significant negative response when they were administered antidepressant medication. The study concluded that antidepressants should not be administered to patients who do not respond to the medication properly to avoid a decline in cognitive functioning. (5)

What are the factors contributing to Cymbalta-induced brain fog? 

There are other factors which can contribute to brain fog while taking Cymbalta, such as: 

Medications: Medications other than antidepressants, such as stimulants, antipsychotics, opioids, etc., have a side effect of cognitive impairment and can cause brain fog in some individuals. 

Dose of the drug: The dose of the drug can influence the effect of the drug. An increased dosage can cause brain fog in some individuals. 

Duration: Chronic treatment with antidepressants has been found to decline cognitive functioning in some individuals. (4)

Drug interactions: Certain drugs, such as NSAIDs, Adderall, selegiline, etc., can increase the concentration of Cymbalta, which can contribute to brain fog.  

Withdrawal effects: Sudden discontinuation or missing a dose of antidepressants can cause withdrawal symptoms, which include cognitive impairment. 

Underlying condition: Any pre-existing condition, such as ADHD, schizophrenia, infection in the brain, encephalopathy, etc., can contribute to impaired cognition and cause brain fog. 

Overdose: If you have consumed a large amount of Cymbalta or a double dose of Cymbalta, you may experience cognitive dysfunction. 

What to do if Cymbalta-induced brain fog does not subside? 

If you are experiencing brain fog at the beginning of the treatment, it will usually subside after a few days as your body gets used to the drug. If you have been experiencing brain fog for a longer period of time and it is affecting your day-to-day activities, consult your physician for further management. 

Your physicain may change the drug or reduce the dose of Cymbalta. Switching a drug or reducing the dose of the drug should be done under the guidance of a qualified physicain to avoid withdrawal symptoms and worsening of your condition. 

You can switch to other drugs which are suitable for you with fewer side effects, such as selective serotonin reuptake inhibitors (citalopram, fluoxetine), tricyclic antidepressants (amitriptyline, imipramine), other SNRIs (venlafaxine, milnacipran), atypical antidepressants (bupropion, trazodone). Selecting a drug to switch depends upon your response to the drug, underlying condition, concomitant medications, etc. and should be done by a qualified physician. 

Address the underlying causes of brain fog, such as stress, sleep disturbance, fatigue, and nutritional deficiency, which can contribute to brain fog. Maintain a healthy and balanced diet in order to gain sufficient nutrients. Participate in physical activities and practice meditation, yoga and deep breathing to help you with stress and fatigue. 

You can consider additional therapy, such as cognitive behavioural therapy and psychotherapy, along with drugs to help treat your illness more effectively. 

How to manage Cymbalta-induced brain fog? 

Here are some general strategies that can help you manage brain fog associated with Cymbalta: 

• If you are experiencing insomnia after taking Cymbalta, take the drug in the morning instead of at night. 
• If you have trouble concentrating, break the tasks into smaller goals, which will help you reduce the feeling of being overwhelmed and help you complete your work.
• Use memory aids, such as calendars, reminders, and notes, if you experience forgetfulness to help you remember. 
• Take frequent breaks while working if you feel exhausted.
• Practise meditation and yoga to manage your stress. 
• Maintain a healthy diet with proper nutrients and protein. Consume food rich in omega-3 fatty acids, such as walnuts. 
• Maintain adequate hydration as it helps remove the toxic metabolite of the drug from the body. 
• Try participating in activities that improve your cognitive functioning, such as puzzles, memory exercises, etc. 

In my perspective as a pharmacist, brain fog can be experienced at the beginning of the treatment with antidepressants. Brain fog subsides within a few days as your body gets used to the medication. Some individuals who are on long-term treatment can also experience cognitive dysfunction. 

I would advise you to consult your physician if you are experiencing any side effects after taking Cymbalta. Avoid abrupt discontinuation of Cymbalta because of side effects, as it may lead to withdrawal symptoms and worsen your condition.
