Depression can make daily life feel overwhelming and unmanageable, especially when standard treatments fail to provide relief. At Oasis Therapeutics, serving patients in Nashua and Concord, New Hampshire, we offer ketamine therapy as an innovative approach to managing depression—particularly for individuals with treatment-resistant symptoms. If you haven’t found success with traditional antidepressants or therapy, ketamine may be the option that brings real change.
Depression is a serious and often debilitating mood disorder that affects millions of people worldwide. It can manifest in many ways, including persistent sadness, a sense of emptiness, difficulty concentrating, low energy, changes in appetite, sleep disturbances, and loss of interest in activities once enjoyed. For some, depression is a temporary phase triggered by life events, while for others it becomes a long-term condition requiring sustained treatment and support.
Many people benefit from traditional treatments such as selective serotonin reuptake inhibitors (SSRIs), psychotherapy, or lifestyle changes. However, a significant number of individuals continue to experience symptoms even after trying multiple treatment approaches. This condition is known as treatment-resistant depression (TRD), and it presents a unique challenge for both patients and providers. For those struggling with TRD, ketamine therapy offers a new avenue of hope.
Ketamine has been studied extensively for its rapid and effective antidepressant properties. Unlike conventional antidepressants that primarily target serotonin and can take weeks to start working, ketamine acts quickly—often within hours—by modulating glutamate, the brain’s most abundant excitatory neurotransmitter. This action helps stimulate the growth of new synaptic connections and supports brain plasticity, which may be impaired in people with chronic depression.
For patients dealing with suicidal thoughts or severe depressive episodes, the speed at which ketamine works can be life-changing. In clinical settings, many patients report a noticeable reduction in symptoms after just a few infusions. At Oasis Therapeutics, we specialize in administering ketamine in a safe, controlled, and medically supervised environment, tailored to each individual’s needs and condition.
Ketamine therapy at Oasis Therapeutics is delivered via intravenous (IV) infusion, which allows for precise dosing and consistent delivery into the bloodstream. Patients typically undergo an initial course of six infusions spaced over two to three weeks. Each session lasts approximately 40 minutes, followed by a brief recovery period during which the patient is monitored by our clinical team.
During the infusion, some individuals may experience mild dissociation, altered perception, or a sense of detachment. These effects are temporary and generally well-tolerated, and our team is present at all times to ensure your safety and comfort. We carefully monitor your vital signs and progress throughout the treatment process.
Following the initial course, patients are evaluated to determine whether ongoing “booster” infusions may be beneficial. While some individuals achieve lasting relief after the first six sessions, others may require periodic maintenance treatments to sustain their results.
Choosing ketamine therapy is an important decision, and our team is here to guide you through every step. At Oasis Therapeutics, we pride ourselves on providing high-quality, compassionate care in a calm and welcoming environment. Your journey begins with a thorough consultation where we review your medical history, current symptoms, and previous treatment experiences to determine if ketamine therapy is appropriate for you.
Our providers are board-certified anesthesiologists with expertise in delivering ketamine safely and effectively. We approach each patient as a whole person, taking into account your physical health, mental health, and life circumstances. This allows us to customize your care and support your recovery with a treatment plan that aligns with your goals.
The experience doesn’t end with the infusion itself. We stay connected with you throughout the process to monitor your progress, adjust your care as needed, and help you integrate the benefits of treatment into your daily life. Whether you are dealing with long-standing depression or experiencing an acute crisis, our goal is to help you find relief and move forward with greater resilience.
If you’ve been diagnosed with depression and have not experienced meaningful relief from standard medications or therapies, ketamine may be a suitable option. Ideal candidates for ketamine treatment are those who:
In addition, we look for patients who are motivated to engage in their healing process and who understand that ketamine is one part of a broader mental health treatment plan. While ketamine can provide rapid symptom relief, long-term recovery often includes continued therapy, lifestyle changes, and other supportive care.
Living with depression can feel isolating—but you don’t have to face it alone. Oasis Therapeutics, proudly serving the communities of Nashua and Concord, New Hampshire, is committed to offering safe, effective, and science-backed treatments for individuals who are ready for a new approach. If you’re struggling with depression that hasn’t responded to traditional care, ketamine therapy may provide the breakthrough you need.
