If depression has not lifted after antidepressants and talk therapy, you already know how tiring that fight gets. Ketamine works differently from the medications most people try first, and for some patients in Miami it helps when nothing else has. This page explains how ketamine treats depression, who it tends to help, what a session at HealthyMe involves, and how to tell whether it is worth a consultation.

Millions of adults live with depression, and a large share of them do not get full relief from the first medications they try. When two or more antidepressants have failed to work, doctors often call it treatment-resistant depression. That label does not mean you are out of options. It means other treatment options deserve consideration after a careful review of your diagnosis and previous care.
At HealthyMe Medical Therapies in Miami Shores, Dr. Carlos Sanchez sees patients from across Miami-Dade who have cycled through medications and therapy without the result they hoped for. Ketamine is one of the treatments he uses for exactly this situation.

Most antidepressants act on serotonin, norepinephrine, or dopamine, and they usually take several weeks to build up before you feel a change. Ketamine takes a different route. It acts on glutamate, one of the brain’s main signaling chemicals, and appears to help neurons form new connections. Research on its NMDA-receptor mechanism shows this can ease depressive symptoms sometimes within hours or days rather than weeks, which is part of why it draws attention for people in acute distress.
Ketamine began as an anesthetic in the 1960s and is still used that way today. Its use for depression is off-label, meaning doctors prescribe it based on clinical evidence rather than a specific FDA approval for that use. A related medication, the esketamine nasal spray sold as Spravato, is FDA-approved for treatment-resistant depression. At HealthyMe, Dr. Sanchez uses intravenous (IV) infusions, which let the dose be measured precisely and adjusted to the person in the chair.

Ketamine is used most often for major depression that has not responded to other treatments. It is also used for depression that comes with suicidal thoughts, since the effect can arrive quickly during a period of real danger. Beyond depression, it is studied and used for anxiety, PTSD, and certain chronic pain conditions, which sometimes travel alongside a mood disorder. If your depression comes tangled up with anxiety or past trauma, that mix is worth raising at your consultation, because it can shape the plan.

Ketamine is generally considered for adults whose depression has not improved with standard treatment. It is not a first-line treatment, and it is not right for everyone. Some heart conditions, uncontrolled high blood pressure, a history of certain psychotic disorders, and active substance misuse can make it a poor or unsafe fit. That is why every patient starts with a full evaluation of their history, current medications, and goals. Not everyone responds to ketamine, and honest care means telling you that before you begin rather than after.

HealthyMe delivers ketamine by IV infusion at the Miami Shores clinic. Here is what a typical visit looks like:
You arrive and get settled in a private, quiet setting. A member of the medical team places the IV and starts the infusion at a low, controlled dose. Over roughly the next 40 to 60 minutes, the medication runs while staff monitor your blood pressure, heart rate, and comfort. Many people feel a floating or dreamlike sensation during the session. When the infusion ends, you rest until you feel steady, and you arrange a ride home rather than driving yourself.
Most people need a short series of infusions rather than a single visit, and some continue with occasional maintenance sessions afterward. Ketamine works best alongside ongoing mental health care, so patients keep seeing their therapist or psychiatrist during treatment. You can read more about how the clinic runs its infusions on the main ketamine therapy page.

In a monitored medical setting, ketamine has a long safety record at the low doses used for depression. The common effects happen during or shortly after the infusion and tend to pass on their own: a dissociated or dreamlike feeling, mild dizziness, nausea, or a temporary rise in blood pressure and heart rate. Staying with the medical team through the session is what keeps these manageable, since someone is watching your vital signs the whole time and can respond right away. Ketamine can be misused recreationally, which is another reason treatment stays supervised, doses stay controlled, and you do not take it home.
Serious risks include breathing problems and misuse. Repeated exposure may affect the bladder or liver. Discuss monitoring and long-term uncertainties with your clinician.

Relief can arrive faster than it does with standard antidepressants, but both the timing and the degree vary from one person to the next. Some people notice a shift in mood within the first few sessions. Others need the full series before they can tell. Because the effect can fade over time, a maintenance plan is common. Dr. Sanchez tracks how you respond and adjusts the plan instead of running everyone through the same fixed protocol.

If depression has worn you down and the usual treatments have not helped, a consultation is the place to start. Dr. Sanchez will review your history and your goals, then tell you honestly whether ketamine is a reasonable option for you. You can see the clinic’s full range of mental health treatments or book a consultation to talk it through.
For many people with treatment-resistant depression, yes. Studies show a single infusion can reduce depressive symptoms quickly, and a series of infusions helps hold the effect. It does not work for everyone, which is why response is monitored closely from the first session.
Faster than standard antidepressants for most responders. Some people feel a change within hours to a few days, rather than the several weeks a typical antidepressant takes. The fuller benefit usually builds over a short series of sessions.
IV ketamine is used off-label for depression, meaning it is prescribed based on clinical evidence rather than a specific FDA approval for that use. The esketamine nasal spray (Spravato) is the FDA-approved form for treatment-resistant depression.
Most people start with a short series of infusions rather than a single visit, then move to occasional maintenance sessions if they respond well. The exact number depends on how you react, which Dr. Sanchez tracks as you go.
Cost depends on your treatment plan and how many sessions you need. The clinic goes over pricing and any financing options during your consultation, so you know the numbers before you commit.
Ketamine can be misused outside a medical setting, which is exactly why treatment is supervised. Doses are low and controlled, the infusion happens under a medical team’s watch, and you do not take medication home with you.
