Side-by-side comparisons
Comparing routes of administration, treatment options, and clinical scenarios so you can ask better questions of your provider.
What we compare and why
Most decisions in ketamine therapy are choices between options — IV versus oral, branded esketamine versus generic racemic ketamine, in-clinic versus telehealth. The right answer depends on diagnosis, response history, access, and budget.
Each comparison summarizes the published evidence, where it is strong, and where it is genuinely uncertain.
