Ketamine infusion therapy involves the use of ketamine infusions for treating mental health conditions and chronic pain syndromes. Despite its growing popularity, the process of ketamine infusion therapy can be unclear to some individuals. This article aims to provide a clear understanding of the treatment process, including the medical uses, how it works, conditions treated, and benefits of ketamine infusion therapy.

What Is Ketamine Infusion Therapy?

The History Of Ketamine

Ketamine is a type of anesthetic, with its origins dating back to the 1960s. The first clinical use of ketamine was in the Vietnam War to treat troops with battle wounds. Since then, ketamine has been used in medical settings for anesthesia during surgeries.

Medical Uses Of Ketamine

Ketamine infusion therapy was first used in the 1990s to treat individuals with chronic pain, particularly those who did not respond well to traditional treatments. Additionally, ketamine has been used in psychiatry as a promising treatment option, known as ketamine therapy, for depression, anxiety, post-traumatic stress disorder (PTSD), and other mental health conditions.

The Emergence Of Ketamine Infusion Therapy

In recent years, ketamine infusion therapy has grown in popularity as a medical treatment option for several conditions. There have been many reported cases of successful ketamine infusion therapy treatment for difficult-to-treat conditions like treatment-resistant depression.


Although ketamine infusion therapy is still a relatively new treatment option, it has shown promising results for individuals who found success with traditional treatments. Research studies have shown that ketamine infusion therapy can help improve mood and decrease symptoms of depression, anxiety, and PTSD.


During a ketamine infusion therapy treatment session, patients are carefully monitored by medical professionals to ensure their safety. The treatment typically lasts for about an hour, and patients may require multiple sessions to achieve optimal results.


One of the benefits of ketamine infusion therapy is that it can provide fast relief for individuals who are struggling with severe mental health symptoms. Unlike traditional antidepressants, which can take weeks or even months to take effect, ketamine infusion therapy can provide relief within hours or days.


It is important to note that ketamine infusion therapy is not a cure for mental health conditions, but rather a treatment option that can help manage symptoms. Patients who undergo ketamine infusion therapy may also need to continue with other forms of treatment, such as therapy or medication, to maintain their mental health.

How Does Ketamine Infusion Therapy Work?

The Role Of Ketamine In The Brain

Ketamine is a medication that has been used for many years as an anesthetic in surgery. However, in recent years, it has gained attention for its potential use in treating depression and chronic pain.


Ketamine is thought to reduce certain types of brain activation that can contribute to depression or pain sensation. The drug blocks the activity of a chemical transporter, which can increase the levels of certain neurotransmitters associated with mood, such as serotonin and norepinephrine. Additionally, ketamine's antidepressant effects are related to its interaction with opioid receptors, which play a role in mood regulation.


Research has shown that ketamine may also help to promote the growth of new brain cells, which can improve brain function and potentially reverse the effects of certain neurological conditions.

The Infusion Process

Ketamine infusion therapy is typically performed as an outpatient procedure, with each treatment session involving a precise dosage of ketamine delivered through an intravenous infusion line. The patient is placed in a comfortable room and connected to the infusion line. The infusion takes approximately 40 minutes to complete, and patients are monitored throughout the duration of the session. Upon completion, patients are evaluated for any immediate side effects before being released.



The infusion process is typically repeated several times over a period of weeks or months, depending on the patient’s response to treatment. During this time, patients may also receive other forms of therapy, such as talk therapy or medication management, to help manage their symptoms.

Duration & Dosage Of Treatment

Each ketamine infusion therapy session is administered at a different dosage of ketamine, depending on the patient’s specific condition and response. Typically, patients receive multiple sessions over a specific period. The number and frequency of sessions depend on the patient and the underlying condition. Patients often experience relief from symptoms within hours or days after the infusion.



Ketamine infusion therapy is not a cure for depression or chronic pain. However, it can be a valuable tool in managing symptoms and improving overall quality of life. Patients who undergo ketamine infusion therapy should continue to work closely with their healthcare providers to monitor their symptoms and adjust their treatment plan as needed.

Conditions Treated With Ketamine Infusion Therapy

Treatment-Resistant Depression

Depression, including major depressive disorder, is a common mental health condition that affects millions of people worldwide. Unfortunately, not all patients respond to traditional antidepressant medication.


Treatment-resistant depression is a type of depression that does not improve with traditional antidepressant medication. Ketamine infusion therapy has been shown to be effective in treating several types of depression, including treatment-resistant depression. Often, patients who have tried other depression therapies without success find relief with ketamine infusion therapy.


Ketamine works by targeting the glutamate system in the brain, which is responsible for regulating mood and emotions. It helps to increase the production of a protein called brain-derived neurotrophic factor (BDNF), which is essential for the growth and survival of neurons. This, in turn, helps to improve mood and reduce symptoms of depression.

Chronic Pain Syndromes

Chronic pain syndromes can significantly affect a person’s quality of life. Ketamine infusion therapy is also used to treat neuropathic pain, a type of chronic pain that can be debilitating and difficult to manage with traditional pain medications. Conditions such as complex regional pain syndrome (CRPS) and fibromyalgia can cause chronic pain that is difficult to manage with traditional pain medications.


Ketamine infusion therapy is also used to treat chronic pain syndromes. Research has shown that ketamine infusion therapy can help relieve chronic pain symptoms and improve overall functioning for several months to years after treatment.


Ketamine works by blocking N-methyl-D-aspartate (NMDA) receptors in the brain, which are responsible for transmitting pain signals. It also helps to reduce inflammation and improve blood flow to the affected area, which can help to alleviate pain symptoms.

Post-Traumatic Stress Disorder (PTSD)

Post-traumatic stress disorder (PTSD) is a mental health condition that can develop after a person experiences or witnesses a traumatic event. It can cause symptoms such as anxiety, depression, and flashbacks, which can significantly affect a person’s quality of life.


Ketamine infusion therapy has been shown to be effective in treating the symptoms of PTSD. Patients often report an improvement in symptoms such as anxiety, depression, and flashbacks after receiving the treatment.


Ketamine works by helping to reduce the activity in the amygdala, which is the part of the brain responsible for processing fear and anxiety. It also helps to increase the production of BDNF, which can help to improve mood and reduce symptoms of depression and anxiety.

Anxiety Disorders

Anxiety disorders are a group of mental health conditions that can cause excessive worry, fear, and apprehension. They can significantly affect a person’s quality of life and make it difficult to carry out daily activities.


Ketamine infusion therapy has also been shown to be effective in treating several anxiety disorders, including generalized anxiety disorder (GAD) and social anxiety disorder. Patients often experience a reduction in symptoms shortly after receiving the infusion.



Ketamine works by helping to reduce the activity in the amygdala, which is the part of the brain responsible for processing fear and anxiety. It also helps to increase the production of BDNF, which can help to improve mood and reduce symptoms of anxiety.

The Benefits Of Ketamine Infusion Therapy

Rapid Symptom Relief

Ketamine infusion therapy is known for its rapid-relief effects. Patients often experience symptom improvement within hours to a few days of receiving the infusion.

Low Risk Of Addiction

Ketamine has been shown to have a low risk of addiction or dependence when used as prescribed in the controlled setting of ketamine infusion therapy. Ketamine infusion therapy is considered safe for individuals without a history of substance abuse or schizophrenia. This makes ketamine infusion therapy a safer alternative to traditional medications that can have a higher risk of abuse or dependency.

Minimal Side Effects

Overall, ketamine infusion therapy is generally safe. The most common side effects are mild and may include nausea, dizziness, or increased blood pressure. These typically resolve shortly after the infusion.

Conclusion

In conclusion, ketamine infusion therapy is a promising treatment option for individuals with specific mental health conditions and chronic pain syndromes. While there are still gaps in the knowledge around the precise mechanism of action, existing evidence suggests that ketamine infusion therapy is a relatively safe and effective therapy option. As always, it is recommended that individuals consult with their physician to determine if ketamine infusion therapy is right for them.


Ketamine infusion therapy has shown promising results in relieving symptoms and improving the overall quality of life for individuals who have not responded well to traditional treatments. With its rapid relief effects, low risk of addiction, and minimal side effects, ketamine infusion therapy offers a safe and innovative approach to mental health and pain management.

Stellate Ganglion Block (SGB) is an emerging mental health treatment that targets key mechanisms linked to depression. In this article, we’ll discuss the science behind SGB and its potential benefits. If you or someone you know is struggling with depression, this information can help you make an informed decision about whether SGB might be the right option. What is a Stellate Ganglion Block (SGB)? What is the Stellate Ganglion? The stellate ganglion is a cluster of sympathetic nerves located on each side of the neck near the first rib. These nerves are part of the autonomic nervous system, which controls automatic body functions like heart rate, blood pressure, and digestion. The term "stellate" means "star-shaped" because the ganglion often looks like a star under a microscope. It helps regulate the body's stress response by controlling norepinephrine, a chemical that triggers the fight-or-flight reaction. When this system becomes overactive, it can cause various physical and psychological problems, including depression. Stellate ganglion block (SGB) therapy may help by reducing the activity of the stellate ganglion, calming the fight-or-flight response, and lessening the damaging effects of prolonged nervous system stress. How Does Stellate Ganglion Block Work? Stellate Ganglion block (SGB) is when a local anesthetic is injected near the stellate ganglion. These drugs inhibit transmission between nerve cells, dampening activity in the ganglion. They typically include lidocaine, bupivacaine, or mepivacaine, which are sometimes combined with a steroid medication. Patients may also receive another medication to relax them before treatment. SGB is typically performed using ultrasound guidance . The injection process lasts no more than 10 minutes, but patients will motinoted for another 30-45 minutes after treatment to ensure their safety. How Does Stellate Ganglion Block Work for Depression? Chronic stress is a major contributor to depression and is often linked to an overactive sympathetic nervous system. People with depression commonly show high levels of cortisol, a hormone that plays a key role in the body's stress response, in their blood stream. Cortisol is helpful in small doses, but when chronically elevated, it can disrupt neural circuits in the brain. Excessive cortisol can lead to: Neurotoxicity - Cortisol can be toxic to nerve cells, especially in the hippocampus, which is crucial for memory and emotional regulation. Overinflammation - Cortisol increases the activity of the body’s natural defense system, resulting in the system causing damage to nerve cells. Impaired synaptic plasticity - Cortisol inhibits the capacity for the brain to “re-wire” itself. This makes it harder for people to adapt to stressful situations and learn new patterns of behaviour. Disrupted sleep - High cortisol can prevent people from sleeping well. During sleep, restorative biological processes occur in the brain, and excess cortisol can prevent these from happening. SGB decreases sympathetic nervous system activity, which can reduce cortisol levels. This can help restore function in brain areas and pathways associated with positive mood, emotional regulation, and stress resilience. Evidence Supporting SGB for Depression To date, there’s very limited evidence supporting the use of SGB for depression. One pilot study found that SGP significantly reduced depression symptoms in people with treatment-resistant depression (TRD) and was well-tolerated. However, there was no significant difference to the placebo group and the sample size was very small. Nonetheless, multiple lines of research show that SGB can alleviate symptoms of post-traumatic stress disorder (PTSD), which shares similarities with depression. In a trial of SGB for PTSD , participants reported significantly lower scores of depression following treatment. Who May Benefit from SGB for Depression? SGB is primarily utilized for treating PTSD, so individuals with PTSD who also experience depression may find SGB beneficial. Additionally, SGB has shown potential in alleviating anxiety symptoms, suggesting it may be advantageous for those dealing with both depression and anxiety. Because SGB isn’t approved by the FDA, it is typically only used when standard treatments like antidepressants and psychotherapy haven’t worked. SGB is an “off-label” treatment, much like ketamine therapy or brain stimulation therapies. Importantly, SGB may not be suitable for everyone because of medical reasons. Contraindications include: Recent myocardial infarction Coagulopathy or anticoagulant therapy Glaucoma Pre-existing contralateral phrenic nerve palsy Severe emphysema Cardiac conduction block Potential Risks and Side Effects of SGB Common Side Effects Most side effects of SGB are temporary and resolve as the anesthetic wears off. These may include: Hoarseness or Voice Changes: The proximity of the stellate ganglion to nerves controlling the voice box can lead to temporary hoarseness. Drooping Eyelid (Ptosis): Temporary drooping of the eyelid on the side of the injection may occur. Red or Bloodshot Eyes: Some individuals may notice redness in the eyes following the procedure. Watery Eyes and Nasal Congestion: Increased tearing and nasal stuffiness are possible but typically short-lived. Sensation of a Lump in the Throat and Difficulty Swallowing: Some individuals may experience a sensation of a lump in the throat and have difficulty swallowing after the procedure. Warmth or Tingling in the Arm or Hand: A warm or tingling sensation in the affected limb may be experienced temporarily. Although uncommon, some individuals may experience more serious complications, such as nerve damage, seizures, and allergic reactions. Given the potential risks, patients interested in SGB at the Albany Clinic will have an in-depth consultation with one of our qualified healthcare professionals before undergoing treatment. They can assess your medical history, current health status, and the potential benefits and risks of the procedure in your specific case.

Finding effective depression treatment can be challenging, especially when cost and insurance coverage add to the stress. Fortunately, for individuals in Illinois, several advanced, insurance-backed options are available beyond traditional antidepressants and therapy. This article explores innovative treatments for depression that are available at our Albany Clinic in Carbondale. Addressing the Need for Affordable Depression Relief in Illinois Depression remains a significant public health concern in Illinois. In 2023, data showed that 18.1% of all adults in the state had a doctor's diagnosis of a depressive disorder . Traditional first-line treatments for depression include medications such as selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs). However, these are not universally effective; approximately one-third of patients are treatment-resistant. Even when these medications do work, they often take a long time to produce noticeable improvements, and unpleasant side effects can deter their use. Talk therapies , such as cognitive behavioral therapy (CBT) and psychodynamic therapy, are also strongly recommended. These treatments can have hugely beneficial effects, but it can require a lot of time commitment for results to show. Moreover, not all therapists accept insurance–especially for those practicing more specialized forms–making the treatment inaccessible for many. Spravato (Esketamine) for Depression What is Spravato, and how does it work? Spravato is an FDA-approved nasal spray that contains esketamine, a derivative of ketamine. Like ketamine, esketamine treats depression by interacting with NMDA receptors , proteins that play a key role in learning and memory. This interaction triggers several neurological processes, including neuroplasticity —the strengthening and forming of connections between nerve cells. Enhanced plasticity may improve the function of nerve circuits responsible for mood regulation, increasing overall well-being. A typical Spravato treatment involves sessions administered under medical supervision, starting with twice-weekly doses and then tapering as appropriate. Whereas antidepressants typically take around four weeks to show an effect, Spravato can have rapid action at alleviating symptoms. A study found that Spravato significantly reduced depression symptoms compared to a placebo drug within just 24 hours of administration. Does Insurance cover Spravato? Due to its FDA approval, Spravato is covered by most major insurance plans in Illinois, including Medicare and Medicaid. However, only patients with a formal diagnosis of treatment-resistant depression (TRD) or major depressive disorder with suicidal ideation (MDSI) are eligible for the treatment. While the medication is usually covered by insurance, patients may still have out-of-pocket costs , including copays , deductibles , and pre-treatment medical evaluations . Your exact expenses will depend on your specific insurance plan. At the Albany Clinic, we’re here to help you understand your costs and maximize your coverage. Transcranial Magnetic Stimulation (TMS) Therapy What is TMS, and how does it work? TMS therapy is a noninvasive procedure that uses magnetic fields to stimulate underactive regions of the brain associated with mood regulation. In depression, TMS targets the dorsolateral prefrontal cortex (DLPFC) , which is often less active in individuals with the condition. TMS therapy works by: Inducing electrical activity in neurons , prompting the release of neurotransmitters involved in mood and motivation. Increasing the activity of neural circuits responsible for mood regulation. Enhancing neuroplasticity , potentially “re-wiring” nerve circuits associated with unhealthy thinking and behavior. The treatment protocol typically consists of daily sessions over several weeks. Each session lasts about 20-40 minutes, during which patients remain awake and alert. Does insurance cover TMS? Since TMS therapy is FDA-approved, some major insurance providers in Illinois cover costs, but unfortunately, the state’s Medicaid does not. If you're considering TMS, check with your insurance provider to see if your plan includes coverage, as eligibility and benefits vary. At the Albany Clinic, we're here to help clarify details and explore options to make treatment more affordable. IV Ketamine Infusion Therapy What is an IV ketamine infusion and how does it work? IV ketamine infusion therapy involves administering ketamine intravenously at sub-anesthetic doses . This approach has shown rapid and robust antidepressant effects, especially in individuals with treatment-resistant depression. IV ketamine shares the same mechanism as Spravato but tends to have more rapid-acting effects. A standard course includes multiple infusions over a set period, with each session lasting approximately one hour. Does insurance cover IV ketamine? Unlike Spravato and TMS, IV ketamine infusion therapy is not FDA-approved for depression treatment and instead is used “ off-label .” This means most insurance plans don’t accept ketamine, and coverage is limited. However, some insurance companies may reimburse some of the treatment costs, such as the evaluation and management part. At the Albany Clinic, we’ll provide you with all the documentation to submit a claim to your insurance provider, but full payment is required before each procedure. Navigating Insurance for Depression Treatment Understanding insurance coverage for depression treatments can be complex. Here are steps to help streamline the process: Verify Coverage : Contact your insurance provider to inquire about treatment coverage specifics. Some insurers require a history of treatment failures with traditional antidepressants before approving coverage for these advanced therapies. Obtain Pre-Authorization : Many insurers require pre-authorization for certain treatments. Ensure all necessary approvals are secured before initiating therapy.
