Frequently Asked Questions About Ketamine Therapy for Mental Health and Pain Treatment (Updated 2024)

Ketamine works by promoting regrowth of broken neural pathways in the brain that are a result from intense stress in individuals with depression and other mental illnesses. This enables better communication between parts of the brain, and can shift patients out of negative mental states. Ketamine infusion therapy involves the use of this medication in the form of intravenous (IV) administration. The onset is quick, within three to four minutes, resulting in the entire ketamine infusion therapy experience typically lasting about forty minutes.

How does ketamine infusion therapy differ from other forms of ketamine?


Refers to the rate and extent to which a drug is absorbed into the body and reaches circulation. IV ketamine is 100% bioavailable, which is different from other forms of administration, such as oral and intranasal. The bioavailability is far less for oral (~20%) and intranasal (~40%) forms of ketamine, which even varies more due to uncontrollable factors such as the absorption of the medication in the nose or oral digestive tract. This means that IV doses are superior to the other forms that have lower bioavailability.


IV ketamine infusion therapy allows for precise dosing, ensuring the attainment of the necessary threshold blood levels of the medication for to create an appropriate antidepressant effect. This proves to be a challenge with nasal and oral forms of ketamine due to the variation in absorption and the inability to guarantee the requisite blood levels.

Furthermore, in cases where patients experience nausea, or require immediate treatment for changes in blood pressure and or heart rate, the close monitoring of patients with an IV makes it easy to provide swift intervention. With an IV in place, other medications to counteract side effects can be administered intravenously, leading to rapid relief. Additionally, intravenous ketamine can be paused or stopped at any time, which is not possible with intramuscular, oral, or nasal forms of the medicine.


IV ketamine is administered within a highly controlled and closely monitored environment. In contrast, there is a growing trend in the use of oral and nasal forms of ketamine at home. However, I would advise caution, especially for individuals less familiar with this medication.

The practice of at-home use has led to an increased potential for recreational and abusive consumption. Surveys indicate that over 50% of patients who opt for at-home ketamine use use it inappropriately, often exceeding recommended dosages or frequency. While severe side effects are exceptionally rare, those who choose at-home ketamine use risk experiencing adverse reactions without immediate access to medical care.

Talk with your primary provider
