How ketamine may help
IV ketamine has been studied as a rapid-acting treatment for depression, particularly treatment-resistant depression. Some patients experience improvement relatively quickly, sometimes within the first day after an infusion. Not everyone responds, and the duration of improvement varies.
When repeated or maintenance treatment is considered, the schedule is individualized according to clinical response, tolerability, and the broader treatment plan.
Ketamine may be used alongside other psychiatric treatment when appropriate. Patients should continue ongoing psychiatric and medical care as recommended by their treating clinicians.

Realistic expectations
Ketamine can produce relatively rapid improvement in depressive symptoms for some patients, but it does not work for everyone. The degree and duration of improvement vary, and some patients may need additional or ongoing treatment to maintain progress.
Our goal is not simply to determine whether you are a candidate for ketamine. During your evaluation, we discuss realistic expectations and compare the treatment approaches that may be appropriate for you. Depending on your symptoms, previous treatments, medical history, preferences, and treatment goals, this may include IV ketamine, antidepressant or other psychiatric medications, Deep TMS, psychotherapy, or a combination of approaches.
These treatments differ in how they work, how quickly improvement may occur, potential side effects, treatment burden, and the durability of benefit. We review these differences with you so that the treatment plan reflects your individual clinical situation rather than assuming that one treatment is best for everyone.
Ketamine is therefore considered as one option within comprehensive psychiatric care—not as a guaranteed response or a stand-alone cure.
What to expect on treatment day
Ketamine infusions are performed in our Fort Worth office.
A typical infusion lasts approximately 40 minutes, followed by a monitored recovery period. During treatment and recovery, patients are observed for potential changes in blood pressure, heart rate, level of alertness, perception, and other adverse effects.
You must have a responsible adult age 18 or older bring you to the appointment, remain onsite during your visit, and drive you home. You cannot be discharged alone or to a rideshare service, taxi, or a driver who did not remain onsite.
If these safety requirements are not met, treatment may be canceled in accordance with office policy.
Side effects, risks, and safety
Ketamine can cause temporary side effects during or after an infusion. These may include dizziness, nausea, increased blood pressure or heart rate, sedation, changes in perception or sense of reality (dissociation), vivid dreams, confusion, or other changes in awareness.
Ketamine can also affect breathing, particularly in certain clinical circumstances or when combined with other central nervous system depressants. Patients are monitored during treatment and recovery, and relevant medications, medical conditions, and substance use are reviewed as part of the evaluation.
Ketamine is a controlled substance and has potential for misuse and dependence. At our practice, IV ketamine is administered only as a supervised, time-limited, in-office treatment. We do not provide ketamine for at-home use.
Ketamine is not appropriate for everyone. Particular caution is required when an increase in blood pressure could pose a serious medical risk. Pregnancy, possible pregnancy, breastfeeding, cardiovascular conditions, substance-use history, and other medical or psychiatric factors should be discussed with your clinician before treatment.
After your infusion
Do not drive or operate machinery for at least 24 hours after your ketamine infusion.
You will need a responsible adult to drive you home. Follow the post-treatment instructions provided by the clinic, including restrictions concerning alcohol, recreational drugs, sedating medications, and activities requiring unimpaired judgment or coordination.
If you develop concerning symptoms after leaving the clinic, contact our office. In an emergency, seek emergency medical care first and then notify our office.
Informed, collaborative care
Before beginning IV ketamine therapy, we discuss the potential benefits, limitations, risks, alternatives, and the off-label nature of treatment. You will have an opportunity to ask questions before providing informed consent.
Ketamine is one of several interventional approaches available at the Institute for Advanced Psychiatry. Depending on your diagnosis, treatment history, preferences, and clinical needs, other options may include medication management, psychotherapy, or Deep TMS.

Research from our practice
Dr. Diana Ghelber and colleagues have shared clinical observations on Deep TMS and IV ketamine for treatment-resistant depression. These observations inform clinical discussion but do not predict an individual patient’s outcome.

Brainsway™ dTMS (TMS) and Brainsway™ dTMS with Ketamine Infusions (TMSK) in Treatment-Resistant Depression (TRD); Real life results — Diana Ghelber and Kumud Khanal. Published abstract, Brain Stimulation. 2018;11(6):e12. View the published abstract.
This small observational study compared Deep TMS with and without ketamine infusions. It did not establish that adding ketamine was superior to Deep TMS alone. The associated poster presents the same work and is not a separate study.
