Frequently asked questions
Who do clinics typically consider a candidate for ketamine therapy?+
Published trials and clinic screening protocols generally describe adults with treatment-resistant depression, severe anxiety, PTSD, or OCD that has not responded adequately to at least two conventional treatments, who are medically stable and without active psychosis, untreated bipolar mania, or active substance use. Candidacy is an individual clinical judgment - only a qualified prescriber who knows your history can make it.
Do clinics expect other treatments to have been tried first?+
Most reputable clinics expect prior trials of standard antidepressants or therapy. This is partly clinical (response rates are best in well-screened patients) and partly insurance-driven (especially for Spravato).
What conditions are commonly listed as contraindications?+
Clinic screening criteria and product labeling commonly list active psychotic disorder, uncontrolled bipolar disorder with manic features, severe uncontrolled hypertension, unstable cardiovascular disease, recent stroke or heart attack, increased intracranial pressure, severe liver disease, pregnancy or breastfeeding (relative), active substance use disorder for ketamine or alcohol.
How do antidepressants interact with ketamine treatment in the research?+
Most treatment-resistant depression trials enrolled patients who were already on stable antidepressants. SSRIs, SNRIs, atypicals, and mood stabilizers are generally compatible. Benzodiazepines and lamotrigine may dampen response and are worth raising with the prescribing clinician.
Is there an age limit?+
Most clinics treat adults 18-65. Some treat older adults with adjusted dosing and tighter monitoring. Adolescent treatment exists but is specialized — seek pediatric psychiatry expertise.
What does the research say about ketamine and bipolar disorder?+
Possibly, with caution. Bipolar depression has been studied with ketamine (mixed results) but switch-to-mania is a real risk. Requires close psychiatric coordination and adequate mood stabilization first.
What if I have a substance use history?+
Past substance use doesn't automatically disqualify you, but active use does — especially of ketamine, alcohol, or stimulants. Clinics will assess time in recovery, treatment history, and current stability. Honest disclosure protects you.
Can pregnant or breastfeeding patients receive ketamine?+
Generally no. Ketamine crosses the placenta and is found in breast milk. Specialized perinatal psychiatry consultation is essential before any consideration.
What about cardiovascular conditions?+
Well-controlled hypertension is usually fine with monitoring. Unstable angina, recent MI, severe heart failure, or aortic disease typically disqualify. Cardiology clearance may be required.
What screening should I expect?+
Detailed psychiatric and medical intake, medication review, validated symptom scales (PHQ-9, GAD-7, PCL-5), blood pressure check, and informed consent discussion. Some clinics require an EKG or labs depending on age and risk profile.
