Is There Any Difference Between The Different Ssris

How SSRIs and SNRIs Work For Anxiety

The different SSRIs seem to work just as well in improving the symptoms of moderate-to-severe depression. SSRIs differ in their side effects and interactions with other medicines. This means that the best choice of SSRI for you will depend on:

  • whether you have other medical conditions
  • if you are taking other medicines
  • your response to antidepressant medicines in the past
  • the possible side effects.

Why Do Ssris Not Work For Everyone

SSRIs fail to treat depression in approximately one-third of all depressed patients. These individuals may continue to suffer from lingering symptoms, such as fatigue, pain, insomnia, trouble concentrating, and lack of enjoyment. The brain is complicated, and science doesnt fully understand all of the mechanisms of depression. Keep in mind that while SSRIs can be helpful, they are by no means the only method of treating depression, anxiety, and other psychiatric conditions.

Which Ssri Should I Take

The different types of SSRIs all work in the same way: Increasing serotonin levels in the brain. They differ in how potent they are, how much they interact with other medications, their side effects, and how fast the body eliminates the drug.

Here are some key differences:


  • Usually prescribed for generalized anxiety disorder

  • More likely to cause an overdose

  • More likely to cause cardiac-related side effects, such as long QT syndrome¹

  • Has fewer interactions with¹¹ other drugs


  • Usually prescribed for generalized anxiety disorder

  • More likely to cause an overdose

  • More likely to cause cardiac-related side effects, such as long QT syndrome

  • Has fewer side effects overall, so it may be more tolerable


  • Usually prescribed for generalized anxiety disorder, panic disorder, obsessive-compulsive disorder , and social anxiety disorder

  • May cause cardiovascular congenital disabilities in pregnant women. Due to this, the FDA updated paroxetine from Category C¹² to Category D .

  • Has more interactions with other drugs

  • Tends to have a greater sedative effect

  • More likely to cause weight gain


  • Usually prescribed for OCD, PTSD, panic disorder, and social anxiety disorder

  • Generally a safer option for pregnant and breastfeeding women

  • Is more effective at a higher dose¹¹



  • More likely to cause gastrointestinal-related side effects

What Is The Rationale For Using Drugs That Affect Serotonin

The monoamine theory of depression has long been influential. It holds that depression results from a deficit of one or more neurotransmitters in the brain. It links the neurotransmitters to specific groups of symptoms. For example, serotonin-dependent signals affect sleep, digestion, mood, and behavior regulation norepinephrine drives the fight-flight-freeze response and dopamine has been linked to motivation, movement, and the capacity for pleasure. However, the notion that a chemical imbalance in the brain generates depression has given way to newer ideas that reflect a greater understanding of how the brain works.

Do Ssris Cause Sexual Dysfunction

What Are SSRIs? How They Work, Side Effects and Alternatives

Approximately 70 percent of people taking SSRIs experience some form of sexual dysfunction, including the loss of . Even as SSRIs increase serotonin levels, they have a dampening effect on the neurotransmitter dopamine, which is associated with the elation of falling in love. Patients should be aware of the potential for some SSRIs to cause problems with sexual desire and performance. In some cases, these issues can be addressed by changing antidepressants, lowering the dosage, or taking a brief, physician-directed medication hiatus

How Can You Get Them

SSRIs are prescription medications, so youll need to see a medical professional such as your family doctor or a psychiatrist. They will discuss your anxiety and review your medical history to ensure SSRIs will be safe and effective for you.

The cost will depend on the specific SSRI and your dosage. Generally, the generic version costs $4-$40 per 30 days, while the brand name tends to be much more expensive, costing around $329-$490 per 30 days. Generics are just as effective as branded medications: They have to pass stringent FDA testing to prove they deliver the same benefits as their branded counterparts.

Do Ssris Make You Gain Weight

Taking antidepressants has been linked to significant weight gain. Individuals who are already overweight are more likely to experience this generally undesirable side effect. Paxil and Lexapro are especially known to contribute to weight gain. Switching medications to avoid or reduce unwanted weight gain may be an option for some patients.

What Is The Clinical Efficacy Of Ssris

According to a six-year meta-analysis, SSRIs were more efficacious than placebos in adults with depression when judged by two criteria: efficacy and acceptability . The efficacy of a given SSRI across thousands of studies varies significantly, ranging anywhere from about one-third as effective to twice as effective as a placebo, but the effect sizes were generally modest. Studies consistently show that antidepressants work best in conjunction with therapies like cognitive-behavioral therapy .

Antidepressants For Anxiety: The Basics

How SSRIs Work
  • Some antidepressants may help to improve the way your brain uses chemicals that control stress and mood, reducing feelings of anxiety.

  • Not all antidepressants are approved to treat anxiety. When an antidepressant is used to treat an anxiety disorder, its generally a selective serotonin reuptake inhibitor or serotonin-norepinephrine reuptake inhibitor .

  • Older antidepressants such as tricyclic antidepressants and monoamine oxidase inhibitors are less commonly used as first-line treatments for anxiety.

  • Antidepressants can take several weeks to start working, meaning its important to keep using them even if you dont notice an immediate improvement in your feelings, anxiety levels and general mood.

  • If youve been diagnosed with an anxiety disorder, your healthcare provider may suggest undergoing psychotherapy in addition to using medication.

  • Antidepressants can be extremely helpful, but they can also have drawbacks. You might experience side effects while using antidepressants, or need to try several medications before finding one thats a good fit for you.

  • If youre prescribed an antidepressant to treat anxiety, dont change your dosage or stop taking it without first talking to your healthcare provider.

Stopping antidepressants suddenly can cause antidepressant discontinuation syndrome and withdrawal symptoms.

Your Ssri Stopped Workingwhat Next

When SSRIs stop working, individuals may consider abrupt discontinuation. If you want to consider a different treatment, it is imperative to consult with a licensed mental health professional or healthcare provider before stopping your medication.

When stopping ones SSRI treatment without medical guidance, patients may experience uncomfortable side effects due to antidepressant discontinuation syndrome. For this reason, it is important for patients to continue taking their medication as prescribed until their provider advises them on gradually tapering it off.

Strategies for treatment-resistant depression may be helpful when SSRI efficacy wanes. These may include increasing dosage, augmenting with other antidepressants, changing medication, or using additional treatments proven to improve depression symptoms, such as Deep Transcranial Magnetic Stimulation .

For some individuals, antidepressant medications lose some of their therapeutic effect over time. Whether antidepressants become less effective or stop working altogether, Deep TMS can be used as an additional treatment to provide more complete symptom relief. Deep TMS is an FDA-cleared, empirically-based treatment utilizing a cushioned helmet to deliver targeted magnetic pulses to regions of the brain associated with psychiatric symptoms. Its patented technology helps regulate the neural activity in these brain regions, improving symptoms over several treatment sessions, without causing any long-lasting side effects.

How Can Antidepressants Help Your Anxiety

Anxiety is a very common mental health disorder. it can cause excessive worry, panic, and fear in peoples everyday lives.

According to the NAMI, Over 40 million adults in the U.S. have an anxiety disorder. Meanwhile, approximately 7% of children aged 3-17 experience issues with anxiety each year. Most people develop symptoms before age 21.

Anxiety can be genetic, caused due to life experiences, brain structure, and even personality traits. Feeling anxious is a part of life, but for some people, their anxiety debilitates their lives every day. They are unable to live normal lives due to the confines their anxiety sets on them.

People with Generalized Anxiety Disorder spend a lot of time worrying about what could happen and often avoid situations in which they feel anxious or could feel triggered. It can keep them from social interactions, keep them on edge and make concentrating a difficulty.

Some anxiety symptoms can include:

  • Feeling tense or jumpy

What Makes A Difference

When someone takes SSRIs, the environment and the things that person does, play a critical role in whether he or she will get better, stay the same, or get worse.

The research suggests that the effects of the SSRIs arent necessarily on serotonin, but on the brains capacity for change. The medication conditions the brain for recovery, and the environment drives the recovery for better or worse. The environment has a heavy influence on how the person will respond to the antidepressants.

This work indicates that simply taking an SSRI is probably not enough. To use an analogy, the SSRIs put you in the boat, but a rough sea can determine whether you will enjoy the trip. For an SSRI to work well, you may need to be in a favourable environment. This may mean that we have to consider how we can adapt our circumstances, and that antidepressant treatment would only be one tool to use against depression.Silvia Poggini.

Strategy No : Systematically Assess Comorbidities

SSRIs for Anxiety: The Wrong Prescription? ⢠truPhys

One reason for a patient to have a suboptimal response to therapy is an incomplete diagnosis.1,22 Patients with panic disorder commonly have other comorbidities including mood and anxiety disorders, and substance use.23 Because these disorders may be associated with panic attacks and anticipatory anxiety23 and may require distinct treatments,4 the diagnosis of panic disorder should consistently trigger a systematic search for other anxiety disorders.22 Because the common comorbidities of panic disorder respond differentially to antipanic treatments, knowledge of these comorbidities also helps in treatment selection.

Unfortunately, most commonly used diagnostic and screening tools for mental health disorders in the primary care setting are not sufficiently comprehensive the less familiar Mini-International Neuropsychiatric Interview ,24 which takes less than 20 minutes to complete, is a more effective screening tool. Finally, it is important to assess the risk of suicide in all patients who have panic disorder.18

Ssris And Benzodiazepines For General Anxiety Disorders

Feeling anxious, worried, and tense? You are not alone! Anxiety disorders are the most common mental illness in the US, and General Anxiety Disorder affects 6.8 million adults every year . When feeling overwhelmed with worries and tension, the first step many people take is to ask their doctors about medication. If you struggle with GAD, and are thinking about starting medication, here is some information about two of the most commonly prescribed types of medication: SSRIs and benzodiazepines.

Selective Serotonin Reuptake Inhibitors include medications such as Zoloft , Prozac , Celexa , and Lexapro . These medications work on serotonin, an important neurotransmitter that plays a role in feelings of well-being and happiness, as well as thinking, memory, sleep, digestion, and circulation. SSRIs are currently considered the first-line medication for many forms of anxiety. If you are considering starting an SSRI, here are some important things to consider:

Benzodiazepines include medications such as Xanax , Ativan , and Valium . These medications strengthen the effect of the neurotransmitter GABA, which is the primary inhibitory signaler in the brain. GABA plays a role in sleep, feeling calm, muscle relaxation, and reduction in brain activity. If you are considering starting a benzodiazepine, here are some important things to consider:

Regardless of who you are or your thoughts on these medications, here are some essential things to know and do when taking medication:

How Do I Know If My Ssris Are Working

Studies recognize a positive medication response when an overall decrease in reporting symptom severity is observed. Specific symptom relief is variable among individuals with a positive response, though physical symptoms often show significant improvement over the first four weeks with the effect leveling off in the following weeks.

SSRI treatment may also bring on a beneficial change in the patients moodthough more gradually, due to the complex process involved with emotional processing. As the biochemical responses affect the way neurons function, individuals perceive their environment with more positive bias. This shift further influences how they interpret their surroundings, eventually resulting in a more positive mood.

How Long Will They Take To Work

SSRIs do not work immediately. Instead, you will only notice improvements in your anxiety and mood once serotonin levels have built up and normalized. Generally, it takes 2-6 weeks to feel the full effect. You might experience an initial improvement in sleep, with overall anxiety improving later.

Even when you start feeling better, its important to continue taking your medication, usually for at least 6-12 months after your anxiety improves. Your doctor will tell you when you can stop taking them.

How Do Antidepressants (SSRI’s) Work?

SSRIs can cause withdrawal symptoms if stopped suddenly. The most common symptoms are dizziness, vertigo, nausea, tiredness, and headache. You may also have similar symptoms to those you had before starting the medication . More serious withdrawal symptoms include feelings like electric shocks, and seizures . To avoid this, it’s best to stop SSRIs gradually, where your dose is reduced slowly over at least 4 weeks.

Stopping Ssris And Snris

SSRIs and SNRIs are not habit-forming or addictive. However, missing doses or stopping treatment abruptly can cause withdrawal-like symptoms. Withdrawal-like symptoms may include nausea, lack of energy, dizziness, headache, and generally feeling off. It is best to wean off SSRIs and SNRIs gradually after discussing with a healthcare professional such as a physician or pharmacist.

Controlled Substances Vs Non

Non-controlled anxiety medications refer to medications that do not carry the risk of dependence or addiction, according to the U.S. Drug Enforcement Administration .

Benzodiazepines, typically prescribed under the brand names Valium, Xanax, Restoril, Ativan and Klonopin, are the oldest and most well-known controlled substances for anxiety. While benzodiazepines have the advantage of working quickly, they carry a high risk of addiction .

Today, the most commonly recommended alternatives to benzodiazepines are SSRIs and SNRIs.

The main difference between SSRIs and SNRIs, compared to Benzodiazepines, is that SSRIs & SNRIs are shown to treat the source of the anxiety, whereas benzodiazepines typically only treat the symptoms.

Snri Vs Ssri: Which One Should I Use

There is currently no consensus on which of the two antidepressants is more effective in treating anxiety. SSRIs do tend to be more widely used than SNRIs and are often considered the first line of defense . According to one 2021 review , side effects tend not to be as severe for SSRIs when compared with SNRIs.

SSRIs and SNRIs can be equally effective options for treating anxiety disorders. Another 2018 review that compared the two medications found that there are no major differences. But reviewers did find that both drugs are most effective in treating social anxiety disorder, specifically.

Also, a 2008 review of SSRIs and SNRIs research showed that SNRIs might be more effective in treating severe depression symptoms, but these differences tend to be modest and arent true for all SNRI drugs . Overall, it is advised that you talk with a medical health professional who should be able to help you determine which antidepressant is best for you.

If Depression Isnt A Chemical Imbalance What Is It

Management Of Panic Disorder In Primary Care

Modern thinking suggests that depression is a problem of circuitry, not chemistry. In this view, symptoms of depression result from failure of synapse formation and changes in the activity level of various emotional signaling centers, set in motion by overactivity of the stress response system, often in response to early adverse experience. Mental health conditions such as depression and anxiety can be seen as aversive yet adaptive responses to adversity.

Like all medicines, SSRIs can cause side effects, but not everyone gets them.

When you first start taking SSRIs, they can cause nausea , vomiting , trouble sleeping , sweating, anxiety or restlessness and diarrhoea .
