SSRIs treat depression by increasing levels of serotonin in the brain. Serotonin is one of the chemical messengers (neurotransmitters) that carry signals between brain nerve cells (neurons). SSRIs block the reabsorption (reuptake) of serotonin into neurons.
Desyrel (trazodone): Desyrel is an antidepressant medication that works by increasing the amount of serotonin available in the body. It also has sedative effects, which is why it is sometimes used to treat insomnia.
It's thought that SSRIs work by increasing serotonin levels in the brain. Serotonin is a neurotransmitter (a messenger chemical that carries signals between nerve cells in the brain). It's thought to have a good influence on mood, emotion and sleep.
A person can raise dopamine and serotonin levels with medications such as antidepressants.
Serotonin is a chemical that the body produces naturally. It's needed for the nerve cells and brain to function. But too much serotonin causes signs and symptoms that can range from mild (shivering and diarrhea) to severe (muscle rigidity, fever and seizures). Severe serotonin syndrome can cause death if not treated.
Although this is beneficial for someone who's depressed, for someone who does not have depression, taking antidepressant medication can cause serotonin to build up in the body, resulting in serotonin syndrome. When serotonin levels are too high, the person may experience symptoms like: Agitation or restlessness.
What are the signs of a lack of serotonin and dopamine? Deficits in serotonin and dopamine can cause a host of signs and symptoms, including depressed mood, fatigue, lack of motivation, decreased sex drive, and difficulty concentrating.
The serotonin test measures the level of serotonin in the blood. Blood is drawn from a vein (venipuncture), usually from the inside of the elbow or the back of the hand. A needle is inserted into the vein, and the blood is collected in an air-tight vial or a syringe. Preparation may vary depending on the specific test.
There is new reason to be cautious about using popular antidepressants in people who are not really depressed. For the first time, research has shown that a widely used antidepressant may cause subtle changes in brain structure and function when taken by those who are not depressed.
The data available suggest that low serotonin levels do not cause depression. However, this does not mean that doctors will stop utilizing antidepressants as a treatment option. Instead, it calls for more research about why antidepressants work the way they do.
Serotonin is a crucial chemical for increasing mood and decreasing anxiety. Researchers have found a clear connection between low serotonin levels and increases in depression, anxiety, and other mental health challenges. Besides being helpful for mental health, serotonin also improves digestion, sleep, and bone health.
Serotonin can stave off depression and provide a feeling a euphoria. When you feel happy and all seems right with the world, you're feeling the effects of serotonin. This hormone is responsible for boosting mood, as well as a host of other functions.
Prozac (fluoxetine) and Wellbutrin (bupropion) are examples of “energizing” antidepressants; whereas Paxil (paroxetine) and Celexa (citalopram) tend to be more sedating.
Escitalopram (Lexapro) Fluoxetine (Prozac) Paroxetine (Paxil, Pexeva) Sertraline (Zoloft)
In almost all of these scenarios, we need to help the body retain and make more serotonin—the chemical in the brain that becomes depleted with chronic pain, chronic digestive issues, chronic stress or anxiety, poor sleep, poor nutrition, etc.
Some inherited genetic disorders may affect the body's ability to make or metabolize serotonin. Lifestyle and other factors that may also play a role include: Hormonal shifts, such as due to beginning or stopping hormone replacement therapy, menopause, pregnancy, or advancing age. Lack of sunlight.
Your Mood or Energy Improve Too Much
If you're taking antidepressant medication and you either feel unusually elated, or you become very terse with your loved ones, feel noticeably more irritable, or have an uncharacteristic bout of rage, then it's likely that your antidepressant dose is too high.
Low levels of dopamine can make you feel tired, moody, unmotivated and many other symptoms. Treatments are available for many of the medical conditions linked to low dopamine levels.
Having low levels of dopamine can make you less motivated and excited about things. It's linked to some mental illnesses including depression, schizophrenia and psychosis.
And luckily, as long as the benefits of the medication outweigh the potential side effects, there's no strong evidence that long-term use of SSRIs poses any major problems. “These medications have been around for decades,” says Dr. Jin Hee Yoon-Hudman, a psychiatrist and medical advisor at Minded.
Do I have to take antidepressants forever is a question that some ask as they struggle with depression. This is one of the more common myths associated with the condition. You do not need to take antidepressants forever nor do you need to get a prescription from a counselor or therapist.
For people with chronic or severe depression, medication may be needed on a long-term basis. In these cases, antidepressants are often taken indefinitely. That is, in part, because depression is not an illness that can be cured.
