Serotonin syndrome: Serotonin syndrome is a serious medical condition that can occur when medications that alter the concentration of serotonin in the brain are taken together. Symptoms of serotonin syndrome may include anxiety, restlessness, sweating, muscle spasms, shaking, fever, rapid heartbeat, vomiting, and diarrhea. Examples of medications that can cause serotonin syndrome include antidepressants, some pain relievers such as meperidine (Demerol) or tramadol (Ultram), St. John's wort, medicines used to treat migraine headaches called triptans, and some street drugs such as cocaine.

Antidepressant medication side effects and drug interactions are barriers to successful treatment for depression. Some side effects of antidepressants resolve with continued use while other side effects can be managed by dose reduction or adding other therapies. Appropriate management of side effects and avoiding drugs and alcohol that may interact with antidepressants may improve the success of depression therapy.

Occasional anxiety is a normal part of life. It’s common for people to feel anxious if there’s conflict in a relationship, a problem at work, a big test looming or a major decision dead ahead. But anxiety disorders involve more than temporary worry or fear. For people with an anxiety disorder, the anxiety does not go away. It often gets worse over time to the point where feelings interfere with their daily functions.3

There are a range of ways to deal with depression, and often they are best used in conjunction with each other. The primary medical options are Cognitive Behavioural Therapy (CBT), antidepressant medication, and in some severe cases, Electroconvulsive Therapy (ECT). Education and coping strategies are also important when learning to manage your depression.
Whether or not someone has side effects, which side effects they have, and how frequent they are will depend on the drug and on the dose used. And everyone reacts slightly differently to drugs as well. The risk of side effects increases if other medication is also being taken. One of the drugs may make the side effects of the other worse. These kinds of drug interactions are common in older people and people with chronic illnesses who are taking several different kinds of medication.
Atypical antidepressants. These medications don't fit neatly into any of the other antidepressant categories. They include trazodone, mirtazapine (Remeron), vortioxetine (Trintellix), vilazodone (Viibryd) and bupropion (Wellbutrin, Aplenzin, Forfivo XL). Bupropion is one of the few antidepressants not frequently associated with sexual side effects.
There are two circumstances under which an anxiety patient may need specific help for depression. One is if he or she has become so depressed in response to anxiety that they no longer have the energy and motivation to overcome the anxiety disorder. In this case, either medication or cognitive behavioral methods can be used to help overcome the depression. The second is the case of a person who experienced a severe depression before the anxiety disorder appeared, a depression which was not just a reaction to the troubles imposed by the anxiety disorder. This depression, called a primary depression, is likely to require medication treatment.
Patients generally tolerate SSRIs well, and side effects are usually mild. The most common side effects are nausea and other stomach upset, diarrhea, agitation, insomnia, and headache. However, these side effects generally go away within the first month of SSRI use. Some patients experience sexual side effects, such as decreased sexual desire (decreased libido), delayed orgasm, or an inability to have an orgasm. Sexual side effects occur less often with newer SSRIs like vortioxetine and vilazodone, compared to the older medications in this category. For those patients, especially for whom anxiety is a prominent symptom of depression, the addition of buspirone may help enhance the effectiveness (augment) the effect of the SSRI while decreasing or eliminating sexual side effects. Uncommonly, some patients experience tremors, hair loss, or gradual weight gain with SSRIs. The so-called serotonergic (meaning caused by serotonin) syndrome is a serious neurologic condition associated with the use of SSRIs, usually when given in high doses or in combination with another SSRI. High fevers, seizures, and heart-rhythm disturbances characterize serotonergic syndrome. This condition is very rare and tends to occur only in very ill psychiatric patients taking multiple psychiatric medications.
Maybe. Some medicines, such as some types of antidepressants, may make it more difficult for you to get pregnant, but more research is needed.15 Talk to your doctor about other treatments for depression that don’t involve medicine if you are trying to get pregnant. For example, a type of talk therapy called cognitive behavioral therapy (CBT) helps women with depression.16 This type of therapy has little to no risk for women trying to get pregnant. During CBT, you work with a mental health professional to explore why you are depressed and train yourself to replace negative thoughts with positive ones. Certain mental health care professionals specialize in depression related to infertility.

Behavioral therapies for depression require a commitment to changing behaviors that make depression worse. They often focus on getting involved in enjoyable or rewarding activities, knowing that if you force yourself to do these things your mood will improve over time. Changing thoughts about certain aspects of life can also be useful. Behavioral interventions for anxiety include safe and gradual exposure to the things that the patient fears. It too involves changing how the patient thinks about those things. Behavioral therapies are effective for depression, and tend to be more effective than medication for anxiety disorders, particularly for long-term relief. For many patients, combining medication and behavioral therapy is better than either one alone for depression, anxiety, and headache.

Symptoms of depression and anxiety are most common among people with chronic migraine, which is when headache attacks occur on 15 or more days a month. For people with fewer headaches, depression or anxiety puts them at risk for more headaches over time. Symptoms of depression and anxiety also impact other areas of health. Migraine patients with depression or anxiety have higher medical costs, are at increased risk for suicide, and have higher levels of disability than migraine patients without depression or anxiety. Also, and perhaps most importantly, headache treatments don’t work as well when the depression or anxiety is not also being treated. Untreated patients are less likely to follow medicine or behavior treatment plans. They also show less response to headache medications, and are more likely to relapse. For these reasons, treating all these conditions is very important.
The pattern of symptoms may fit a pattern within any type of depression. For example, a person who suffers from persistent depressive disorder, major depressive disorder, bipolar disorder, or any other illness that includes depression can have prominently anxious, melancholic, mixed, psychotic, or atypical features. Such features can have a significant impact on the approach to treatment that may be most effective. For example, for the person whose depression includes prominent anxiety, a focus of treatment is more likely to be effective if the sufferer's pattern of repeatedly going over thoughts is a major focus of treatment, versus an individual with melancholic features, who may need more intensive support in the morning when the intensity of depression tends to be worse, or versus a person with atypical features, whose tendency toward weight gain and excessive sleeping may require nutritional counseling to address dietary issues.
The causes of SAD are unclear, says NIMH, but research suggests it may be due to seasonal fluctuations in levels of serotonin, a brain chemical that helps regulate mood, or to an overproduction of melatonin, the hormone that regulates sleep. Scientists also posit that people with SAD may produce too little vitamin D, which impacts serotonin activity.
Even though clinical depression tends to occur in episodes, most people who experience one such episode will eventually have another one. Also, it seems that any subsequent episodes of depression are more easily triggered than the first one. However, most depression sufferers recover from the episode. In fact, individuals who have mild depression and receive treatment with medication tend to respond equally as well to sugar pill (placebo). Those with more severe depression seem to be less likely to get better when taking placebo versus taking antidepressant medication. Other encouraging information is that research shows that even people from teenage through adulthood who do not improve when treated with a first medication trial can improve when switched to another medication or given another medication in addition to psychotherapy. For individuals who experience thoughts of suicide, preventing access to firearms and other highly lethal means of committing suicide are important ways to improve their safety and that of those around them.

Fluvoxamine enhances serotonin activity due to selective reuptake inhibition at the neuronal membrane. It does not significantly bind to alpha-adrenergic, histamine, or cholinergic receptors and thus has fewer side effects than tricyclic antidepressants. Fluvoxamine is a strong inhibitor of cytochrome P-450. Although fluvoxamine is FDA approved only for obsessive-compulsive disorder, it is commonly prescribed for other psychiatric disorders, including social anxiety disorder, posttraumatic stress disorder, pain disorder, and major depression.
I have also suffered a recent brain injury (concussion). Medication is not an option for my panic and anxiety symptoms. I am now taking cranio- sacral therapy providing significant relief. How I recovered from my horrific addiction to phsyco meds 10 years ago is still a very painful memory not to be easily forgotten. I am convinced & am choosing a holistic safer route instead of the dead end road of pharmaceutical therapy. God Bless. Julie
