Remeron vs Cymbalta
Introduction
For patients grappling with major depressive disorder (MDD) or other types of depression, certain medications that modify the levels of neurotransmitters—the brain chemicals associated with mood—can play an integral role in stabilizing depressive lows and managing symptoms. Remeron and Cymbalta are such drugs commonly prescribed for managing depression. They each influence different neurotransmitters in the brain but both have mood-stabilizing effects on patients suffering from depression. Remeron, also known as mirtazapine, is classified as a noradrenergic and specific serotonergic antidepressant (NaSSA), primarily affecting levels of norepinephrine and serotonin. On the other hand, Cymbalta, or duloxetine, falls under the category of serotonin-norepinephrine reuptake inhibitors (SNRIs), impacting both norepinephrine and serotonin concentrations.

What is Remeron?
Mirtazapine (the generic name for Remeron) is an antidepressant that belongs to the class of drugs known as atypical antidepressants. It was first approved by the FDA in 1996. Remeron primarily increases levels of free norepinephrine and serotonin by acting as an antagonist on specific adrenergic and serotonergic receptors, effectively enhancing central noradrenergic and serotonergic activity. It is commonly prescribed for major depressive disorder. Unlike other classes of antidepressants, mirtazapine has a unique mechanism which results in it having different side effects.
On the other hand, Duloxetine (the generic name for Cymbalta) falls under another class known as SNRIs or Serotonin-Noradrenaline Reuptake Inhibitors - it too increases levels of both serotonin and norepinephrine by preventing their reabsorption into cells in the brain. Approved by the FDA in 2004, this drug not only treats depression but also anxiety disorders, fibromyalgia, chronic neuropathic pain among others due to its unique dual action on two neurotransmitters.
What conditions is Remeron approved to treat?
Remeron is approved for the treatment of various types of depression:
- Major depressive disorder (MDD)
- Depression associated with bipolar disorder
- Anxiety disorders
In some cases, it may also be used off-label to treat other conditions such as insomnia and post-traumatic stress disorder (PTSD). It should be noted that while Remeron can be effective in treating these conditions, Cymbalta might also be considered depending on the specific symptoms and circumstances. Always consult with your healthcare provider before making any changes to your medication regimen.
How does Remeron help with these illnesses?
Remeron manages depression by increasing the amount of serotonin and norepinephrine in the synapses of the brain. It achieves this by blocking their reabsorption into neurons, thus allowing these neurotransmitters to remain available for longer periods. Serotonin and norepinephrine are both neurotransmitters that play crucial roles in mood regulation, cognition, memory, sleep patterns among other functions. It's believed that individuals with depression have relatively lower levels of these neurotransmitters. Therefore, by increasing their availability, Remeron can help limit depressive symptoms and aid patients in managing their condition and stabilizing their mood.
What is Cymbalta?
Cymbalta, also known by its generic name duloxetine, is a serotonin-norepinephrine reuptake inhibitor (SNRI). It works by increasing the levels of serotonin and norepinephrine in the brain to help maintain mental balance. Unlike Remeron, which is a noradrenergic antagonist specific serotonergic antidepressant (NaSSA), Cymbalta does not primarily target histamine or alpha-1 receptors that often lead to weight gain and sedation. Instead, it inhibits the reabsorption of both serotonin and norepinephrine neurotransmitters without having much effect on other receptors. The FDA approved duloxetine first in 2004.
By focusing on two separate chemical messengers, Cymbalta can help alleviate depression symptoms for patients who may not respond well to traditional SSRI drugs like Prozac or even NaSSAs such as Remeron. Additionally, this dual action means that SNRIs such as Cymbalta generally offer a different side-effect profile compared to SSRIs or NaSSAs – notably it has less likelihood of causing significant weight gain or feelings of drowsiness.
What conditions is Cymbalta approved to treat?
Cymbalta is a versatile medication approved by the FDA for several uses. These include:
- Major depressive disorder (MDD)
- Generalized anxiety disorder (GAD)
- Diabetic peripheral neuropathic pain
- Fibromyalgia, and chronic musculoskeletal pain
Its wide range of applications make it a particularly useful tool in managing both mental health disorders and certain types of chronic pain conditions.
How does Cymbalta help with these illnesses?
Serotonin and norepinephrine are two neurotransmitters that play key roles in mood regulation, pain perception, and a host of other bodily functions. Low levels of both have been implicated in depression. Cymbalta works by increasing the levels of serotonin and norepinephrine available in the brain, thereby helping to alleviate some symptoms of depression and anxiety disorders. Its dual action on these two neurotransmitters may also contribute to its effectiveness in treating chronic musculoskeletal pain, including discomfort from osteoarthritis and chronic lower back pain. Unlike Remeron which primarily increases serotonin concentrations at nerve endings, Cymbalta ensures a balance between both serotonin and norepinephrine, making it an effective treatment option when patients do not respond well to "typical" SSRI antidepressants or may be dealing with certain types of chronic pain conditions along with depressive symptoms.
How effective are both Remeron and Cymbalta?
Both mirtazapine (Remeron) and duloxetine (Cymbalta) have proven records of efficacy in treating depression, with their approvals by the FDA coming about a decade apart. They act on different neurotransmitters which means they may be prescribed under varying circumstances. The effectiveness of mirtazapine and duloxetine was directly compared in a 2009 double-blind clinical trial; both drugs demonstrated similar abilities to alleviate symptoms of depression, along with comparable safety profiles.
A 2016 review of meta-analysis reports on mirtazapine showed that it is effective from the first week of treatment at alleviating depressive symptoms, its side effect profile is generally favorable when compared to many other antidepressants, and it's well-tolerated across various demographic groups including elderly patients. Moreover, as an atypical antidepressant developed later than SSRIs or SNRIs like fluoxetine or duloxetine respectively, there has been considerable study into its unique mechanism and effectiveness in treating depression.
On the other hand, a 2012 review and meta-analysis indicated that duloxetine seems more effective than placebo for depression treatment while showing similar efficacy to most common antidepressants. However, due to certain side effects like nausea or dry mouth associated with this drug class known as SNRIs (serotonin-norepinephrine reuptake inhibitors), it might not always be considered as a first-line option but rather after SSRIs have failed or shown intolerance. There is also significant research involving use of duloxetine alongside another type of medication such as an SSRI so data confirming its stand-alone treatment efficacy are less robust than those for mirtazapine.

At what dose is Remeron typically prescribed?
Oral dosages of Remeron (Mirtazapine) typically start at 15 mg/day for treating major depressive disorder in adults. However, depending on the patient's response to treatment, the dosage can be gradually increased over a few weeks up to a maximum of 45 mg/day. On the other hand, Cymbalta (Duloxetine) is usually started at an initial dose of 60 mg once daily but some patients may benefit from starting at 30 mg once daily for one week before increasing to 60mg every day. The maximum dose should not exceed 120mg per day in any case. Both drugs are not recommended for use in children or adolescents under the age of 18.
At what dose is Cymbalta typically prescribed?
Cymbalta treatment is typically begun with a dose of 20-30 mg/day. This can be increased after a week to the commonly recommended dosage of 60 mg/day, taken as one single dose or divided into two doses, spaced approximately 12 hours apart. In some cases and under close supervision by your healthcare provider, the maximum dose may go up to 120 mg/day divided into two doses of 60 mg each. However, this higher dosage would only be considered if there's no meaningful response after several weeks at the standard daily dosages.
What are the most common side effects for Remeron?
Common side effects of Remeron may include:
- Drowsiness, dizziness
- Increased appetite
- Weight gain
- Dry mouth
- Constipation
On the other hand, Cymbalta often has side effects such as:
- Nausea
- Dry mouth
- Sleepiness, fatigue
- Insomnia (trouble sleeping)
- Loss of appetite or weight loss -Diarrhea/constipation -Sweating
These lists do not include all possible side effects. If you notice any other abnormal results while using either medication, please contact your healthcare provider immediately.
Are there any potential serious side effects for Remeron?
When comparing Remeron (Mirtazapine) to Cymbalta (Duloxetine), it's essential to note that both medications come with their own set of potential side effects. For Remeron, these might include:
- Suicidal thoughts or a worsening of depression
- An allergic reaction characterized by hives, difficulty breathing or swelling in the face, lips, tongue or throat
- Vision changes such as blurred vision and tunnel vision accompanied by eye pain and seeing halos around lights
- Heart-related issues like rapid heartbeat and chest fluttering; shortness of breath along with sudden dizziness can also occur.
- Low sodium levels - symptoms include headache, confusion, slurred speech, severe weakness, vomiting.
- Severe nervous system reaction: rigid muscles leading to high fever, sweating confusion fast heartbeats & tremors.
Cymbalta on the other hand may lead to serious side effects such as:
- Serotonin syndrome symptoms including agitation hallucinations fever sweating shivering fast heart rate muscle stiffness twitching loss of coordination nausea vomiting diarrhea.
It is important to consult your healthcare provider if you notice any adverse effects while taking either medication for proper guidance.
What are the most common side effects for Cymbalta?
Common side effects of Cymbalta may include:
- Dry mouth and increased sweating
- Blurred vision or other changes in vision
- Nausea, vomiting, stomach pain, loss of appetite or constipation
- Difficulty sleeping (insomnia)
- Feeling jittery or nervous with possible tremors
- Increased heart rate
- Confusion, agitation or feelings of hostility
- Possible skin rash
- Potential weight loss
- Frequent urination
- Headaches and dizziness
-Muscle aches or joint pain
Do remember that not every patient experiences all these symptoms. However, if you are on Cymbalta and notice any unusual physical or emotional changes that concern you, it's important to seek medical advice promptly.
Are there any potential serious side effects for Cymbalta?
When using Cymbalta, it's important to be conscious of any adverse reactions that may occur. In some cases, these could include:
- Signs of an allergic reaction such as hives; difficulty breathing; swelling in the face or throat
- Increased thoughts about suicide or hurting yourself
- Seizures (convulsions)
- Unusual changes in mood or behavior, including feelings of agitation and restlessness
- Vision problems like blurred vision, eye pain or swelling
- Fast heartbeats or irregular heartbeat
- High levels of serotonin leading to symptoms such as hallucinations, fever, fast heart rate and severe nausea.
If you notice any signs indicative of these side effects while taking Cymbalta, seek emergency medical attention immediately.
Contraindications for Remeron and Cymbalta?
Just like Prozac and Wellbutrin, both Remeron (mirtazapine) and Cymbalta (duloxetine), which are also antidepressants, may possibly aggravate symptoms of depression in some people. If you observe your depression getting worse or if there is an increase in suicidal thoughts or behavior while taking these medications, it's crucial to seek medical help immediately.
Neither Remeron nor Cymbalta should be taken if you have been using monoamine oxidase inhibitors (MAOIs). Always inform your healthcare provider about any other medications you're currently on; MAOIs need approximately 5 weeks to completely leave your system to avoid potentially dangerous interactions with Remeron and Cymbalta. Furthermore, because both drugs can cause liver damage, they must not be used by individuals who already have liver disease.
How much do Remeron and Cymbalta cost?
For the brand name versions of these drugs:
- The price of 30 tablets of Remeron (30 mg) averages around $370, which works out to approximately $12.33/day depending on your dose.
- The price for 20 capsules of Cymbalta (60 mg) is about $470, working out to roughly $23.50/day.
Thus, if you are in the higher dosage range for Remeron (i.e., 45 mg/day), then brand-name Cymbalta may be less expensive on a per-day treatment basis. However, cost should not be a primary consideration in determining which one of these drugs is right for you.
For the generic versions - mirtazapine and duloxetine respectively - costs are significantly lower:
- Mirtazapine (15mg tablets) is available in packs ranging from 7 up to 1000 tablets with prices starting as low as $.10/day if buying large quantities upfront but can go up towards approximately $.70/day.
- Duloxetine typically comes in packages varying between seven and eighty-four capsules with daily costs ranging from about $.40 when bought in bulk and potentially exceeding $2.00 per day at smaller volumes or higher dosages.
Popularity of Remeron and Cymbalta
Mirtazapine, known by the brand name Remeron, was prescribed to an estimated 2.1 million people in the US in 2020. Mirtazapine is classified as a tetracyclic antidepressant and it accounted for about 5% of total prescriptions within its class that year. It's a unique drug that has been gaining some popularity over recent years due to its sedative properties, making it particularly useful in patients with insomnia.
On the other hand, Duloxetine, under brands such as Cymbalta, had approximately 10 million prescriptions filled in the USA during the same year. Classified as a serotonin-norepinephrine reuptake inhibitor (SNRI), Duloxetine accounts for nearly 40% of SNRI prescriptions and around 15% of all antidepressant prescriptions overall. The usage of Duloxetine has seen steady growth since its approval by FDA back in 2004.
Conclusion
Both Remeron (mirtazapine) and Cymbalta (duloxetine) have a long history of use in treating depression, with numerous clinical studies and meta-analyses indicating that they are more effective than placebo treatments. In certain cases, these medications may be used together but this has to be carefully considered by a physician as they also carry contraindications when combined. Due to their different mechanisms of action, with Remeron acting primarily on norepinephrine and serotonin receptors while having an antagonistic effect on some subtypes of serotonin receptors, and Cymbalta inhibiting the reuptake of both serotonin and norepinephrine, they tend to be prescribed under varying circumstances.
Remeron is often considered for patients who have trouble sleeping or lack appetite due to depression since it can cause drowsiness and weight gain as side effects. Conversely, Cymbalta might be favored in patients suffering from co-morbid chronic pain conditions because it has been shown to help reduce pain symptoms along with treating depression.
Both drugs are available in generic form which represents significant cost savings especially for those paying out-of-pocket. Both Remeron and Cymbalta may require an adjustment period implying that effects may not immediately show up after starting the medication.
The side-effect profile between these two drugs shows similarity although each drug does come with its unique set of side-effects; despite being generally well-tolerated overall. For both medications however, close monitoring is necessary particularly during early stages of treatment due to potential worsening depressive symptoms or emergence of suicidal thoughts.
