Who Is Most At Risk For Getting Serotonin Syndrome

Anyone who takes a substance that affects the bodys serotonin levels could be at risk for serotonin syndrome.

Its important to keep close tabs on all medications you take. Its also important to talk with your doctor regularly. These precautions can help you spot signs of serotonin syndrome early. Early identification may help you avoid more severe symptoms.

You have a higher risk of developing serotonin syndrome symptoms if you:

  • Take more than one serotonergic medication, such as an antidepressant and cough medicine.
  • Recently increased dosage of a serotonergic medication.
  • Use St. Johns wort or ginseng.
  • Use certain illegal drugs.

What Are The Most Common Serotonin Syndrome Symptoms

Serotonin syndrome symptoms may be mild or severe. Symptoms may start soon after you take a new medication or increase the dose. Symptoms can occur within hours.

Some cases of serotonin syndrome can be life-threatening. People need quick treatment for the condition. If you are taking a medication that affects serotonin and experience any of the following symptoms, call your doctor or visit an urgent or emergency care facility right away:

  • Mood changes, such as irritation or confusion
  • Increased heart rate and increased blood pressure

What Is Serotonin Syndrome

Serotonin syndrome occurs when someone has an excess of the neurotransmitter serotonin in their nervous system. The conditions symptoms generally fall into three categories:

  • Altered mental status
  • Neuromuscular hyperactivity
  • Autonomic hyperactivity

Because serotonin is produced primarily in the gastrointestinal tract, digestive problems like nausea and diarrhea are common. A person experiencing serotonin syndrome may also be confused, dizzy, or disoriented. In severe cases, an individual may develop hallucinations and seizures.

Serious cases of serotonin syndrome can be fatal if left untreated. However, serotonin syndrome is usually very treatable. Recovery often occurs within 24 hours of seeking medical help.

How Long Does Serotonin Syndrome Last

How long serotonin syndrome lasts is dependent on how high serotonin levels are in the body.

In cases where serotonin syndrome is only present in a mild form, symptoms may be alleviated within 24 hours of discontinuing the medication causing the uptake in serotonin. However, some antidepressants can cause symptoms to last longer as serotonin levels may take weeks to return to normal.

What Are Common Serotonin Syndrome Treatments

In mild cases, stopping a medication or changing your dosage may make your symptoms go away. Your bodys serotonin levels may go back to normal within a few days. Do not change medications without a doctors advice.

Doctors may prescribe medications that stop your body from producing serotonin. These medications can help relieve symptoms.

If you do not treat the symptoms, serotonin syndrome can be serious. In some cases, the condition may be life-threatening. Some people need treatment in a hospital, where they can be watched closely.

How Is Serotonin Syndrome Treated

In most cases, serotonin syndrome can be resolved within 24 hours. Treatment can be as simple as stopping the medication that was causing an increase in serotonin. Mild symptoms can be cleared up very quickly in this way.

If an individual has mild symptoms but requires the medication , they may discuss the risks and benefits with their care provider. Often a compromise can be found by reducing the medication dosage. If the current dosage is necessary, then a clinician should closely monitor the patient for any worsening of symptoms.

More severe symptoms of serotonin syndrome may require hospitalization. Doctors will likely monitor a persons vitals and watch for any withdrawal effects. In extreme cases, someone with serotonin syndrome may require a breathing tube, feeding tube, or sedation. If the person is experiencing muscle spasms, a doctor might use a medication that temporarily paralyzes muscles as a preventative measure. This helps guard against damage to the muscle tissue and kidneys.

If you start taking a serotonin-related medication, increase your dosage, or begin another in combination with one you are already taking and too much serotonin accumulates, you will feel the effects within several hours. The majority of cases occur within 24 hours and some within six hours of initiation of medication or change in dose.

Symptoms can range from mild to severe and depend on the level of serotonin in your body. At best, the signs and symptoms of serotonin are unpleasant at worst, they can be extremely worrying and require intensive medical treatment.

Gut Bacteria And Serotonin

Your gut is home to the bacteria that helps it produce serotonin. Studies have found that several species of gut bacteria are missing in people with depression, and that imbalances in gut flora can lead to mood imbalances.12

This is why I recommend everyone take a probiotic to ensure a healthy balance of the good bacteria in their gut. In fact, probiotics are one of the four essential supplements that I recommend everyone take every day.

However, not all probiotics are created equal. Probiotic strength is measured in colony-forming units . The CFU tells you how much bacteria is present in that probiotic. Unfortunately, many probiotics have a short shelf-life and require refrigeration, as CFUs can die off quickly.

Thats why I formulated Probiotic 30 Billion and Probiotic 100 Billion to include 14 of the most important strains, and made absolutely sure that there were enough viable CFUs in each capsule to support digestive health and immune function for those looking for the perfect level of daily probiotic maintenance.

Gut serotonin is crucial for balancing your mood and supporting healthy digestion. Taking a probiotic with 30 billion or 100 billion CFUs, getting regular sunshine and exercise, and eating plenty of tryptophan-rich foods are all powerful ways to boost your serotonin levels and support your gut health.

Why Is Serotonin Sometimes Toxic

Serotonin syndrome, or serotonin toxicity, is a rare and potentially life-threatening condition caused by dangerously high levels of serotonin in the brain. It’s generally caused by taking two or more medications that raise serotonin levels in the central nervous system.

Substances that may contribute to excess serotonin levels include:

SSRIs, serotonin and norepinephrine reuptake inhibitors , tricyclic antidepressants, and monoamine oxidase inhibitors are all classes of antidepressant medications that have been implicated in the development of serotonin syndrome.

These antidepressants are often prescribed to treat depression and anxiety disorders, including panic disorder.

Serotonin syndrome has been reported perioperatively as a result ofserotonergic potentiation secondary to the coadministration of fentanyl duringanaesthesia , to the useof methylene blue dye during parathyroid surgery and to the use of linezolid in thetreatment of severe infection . Linezolid is a synthetic oxazolidinone antibiotic with ahalf-life of 5 h it was originally developed for use as an antidepressantowing to its reversible non-selective MAO inhibitory properties. Itscoincidental antimicrobial properties led to its further development andsubsequent use in treating specific Gram-positive infections such asmethicillin-resistant Staphylococcus aureus . Serotonin syndrome hasrecently been described following rewarming in patients who had been treatedwith therapeutic hypothermia for cardiac arrest and in a breastfed neonate whose mother hadbeen taking 60 mg fluoxetine daily .

Can Exercise Cause Insomnia

Serotonin Syndrome From Mixing Prescriptions Could Be ...

In general, the answer is no. However, some people experience exercise-induced insomnia if they exercise too close to bedtime, while others have no trouble falling asleep right afterwards.

For some people, exercising too late in the day can keep them up at night. In addition to elevating your mood, the endorphin release associated with exercise can energize your brain, leading some people to feel more alert. For this reason, experts recommend avoiding exercise at least 2 hours before bed so those effects can wear off.

However, the drop in body temperature that occurs after exercising can begin 30 to 90 minutes later, which may help with falling asleep.

To figure out the right time for you to exercise, consider keeping a sleep diary. Record when you exercise, what type of exercise you did and for how long, when you went to bed, and how long it took you to fall asleep. Just make sure you dont make any other changes that otherwise might affect your sleep and interfere with your results.

Is Mild Serotonin Syndrome Serious

Serotonin is a naturally occurring chemical in the body that acts as a neurotransmitter, or a messenger between nerve cells. And the role of serotonin is important. Serotonin manages mood and memory as well as assists in sleep, digestion, sexual function, blood clotting, and more. However, too much serotonin can result in mild serotonin syndrome or more severe serotonin toxicity.

The body requires certain serotonin levels to function properly. When a person does not have enough of this chemical, problems can arise. In fact, low serotonin symptoms are thought to include ailments such as the following:

  • Irritability
  • Impulsivity

It is important to recognize that serotonin does not work alone to produce these conditions. However, it does play an important role. When prescription medications or over-the-counter serotonin supplements are taken in an effort to increase serotonin, the result can be too much serotonin within a persons system.

    Can A Lack Of Exercise Induce Insomnia

    Multiple studies have found that regular exercise correlates with better sleep. Across age groups, individuals who have a regular exercise routine are less likely to have insomnia and sleep issues. Further, those who are more physically active tend to be less likely to develop insomnia later in life, indicating that exercise also acts as a protective function against insomnia.

    Conversely, a lack of exercise is associated with insomnia. Along with factors like poor health, stress, old age, and unemployment, lack of regular exercise is a predictor of insomnia. Problematically, when people are suffering from insomnia, it can be harder to be physically active due to higher levels of daytime fatigue and sleepiness.

    The Surprising Way To Increase Serotonin With Food

    Serotonin Syndrome: What Happens When You Have TOO much Serotonin?

    One seemingly obvious way to increase serotonin would be to eat foods that contain it.

    While some foods such as walnuts, hickory nuts, bananas, pineapple, kiwis, plums, and tomatoes do contain serotonin, eating them is not an effective strategy since the serotonin in these foods does not enter the brain.

    Another option would be to eat foods containing serotonins precursor, tryptophan.

    Tryptophan is an amino acid found in most protein food sources.

    But trying to raise serotonin levels by eating tryptophan presents an interesting paradox.

    Protein blocks serotonin synthesis and, consequently, levels of both tryptophan and serotonin actually drop after eating protein.

    There are only a handful of foods known to increase serotonin naturally by other mechanisms:

    There are many kinds of natural serotonin boosters herbs, vitamins, minerals, and more.

    Two of the most popular serotonin supplements are the amino acids tryptophan and 5-HTP.


    Tryptophan is a rare case where supplements work better than foods containing tryptophan.

    As mentioned above, eating protein both tryptophan and serotonin levels.

    But tryptophan supplements provide a nice workaround to this dilemma.

    They increase brain levels of serotonin while bypassing proteins negative effect on serotonin formation.


    5-HTP is converted into both serotonin and melatonin, making it popular for those with both depression and insomnia.

    But this is not our favorite serotonin-boosting supplement.

    What Causes Serotonin Syndrome

    Serotonin syndrome is ultimately a bad reaction to medication. It most often occurs after a person takes multiple drugs that increase serotonin. For example, someone who uses antidepressants may take cold medication. Both drugs can boost serotonin, raising the neurotransmitter levels much higher than either medication would alone.

    Serotonin syndrome can also happen if a person starts a new medication or increases their dosage. It can be difficult to predict which medications or dosages will pose a risk though. A certain level of serotonin may be therapeutic for one person and toxic for another.

    Selective serotonin reuptake inhibitors and selective norepinephrine reuptake inhibitors are the most common drugs linked to the condition. Other substances that can increase serotonin include:

    • Other antidepressants
    • Triptan migraine medications
    • Over-the-counter cold medicines that contain dextromethorphan
    • Certain herbal supplements
    • Certain recreational drugs

    Symptoms of serotonin syndrome typically appear within the first 24 hours of starting or adjusting ones medication regimen. There is currently no one medical test for serotonin syndrome. A doctor would likely perform several specific tests to evaluate organ function, check for hormonal imbalances, and rule out other potential conditions, such as drug overdose.

    How To Naturally Boost Serotonin Levels

    Conventional medicine uses antidepressants to boost serotonin. However, as I mentioned, these medications have harmful side effects such as dizziness, insomnia, constipation, and increased feelings of anxiety.8 They are also very difficult to stop taking and can cause really awful withdrawal symptoms.9

    The good news is that you can boost your serotonin levels without the use of medications through diet and lifestyle changes. Here are four ways you can naturally boost serotonin levels:

    Too Much Serotonin And Social Anxiety

    Its estimated that 15 million Americans suffer from social anxiety disorder.

    This condition is characterized by overwhelming fear and self-consciousness in social or performance situations and goes way beyond ordinary shyness.

    Its been thought that social anxiety was caused by a lack of serotonin, so serotonin-boosting antidepressants are commonly prescribed.

    But new research is turning that idea on its head.

    By using PET cameras and special tracers, researchers at Swedens Uppsala University were able to measure serotonin synthesis in the brains of patients.

    The study results, which were published in the prestigious Journal of the American Medical Association, concluded that individuals with social phobia make too much serotonin and the more serotonin they produce, the more anxious they become.

    The study participants with social phobia produced more serotonin in the amygdala, the brains fear center.

    The results of this study have been called a major leap forward in the understanding of mental disorders.

    To further characterize thermoregulation of PCPA-treated mice, we housed them in a cold room at 4°C for 4 h. When presented with this cold challenge, PCPA-treated mice became severely hypothermic after only 1 h, in contrast to saline-treated mice . In all PCPA-treated mice, TC dropped below 30.0°C after 2 h of exposure to 4°C, requiring three of the four mice to be removed from the cold before the experiment ended. In none of the saline-treated mice did TC drop below 34.3°C.
