What is Ketamine-Assisted Psychotherapy?

It may be beneficial to know people have found answers in using psychedelic medicine; also referred to as Ketamine-Assisted Psychotherapy (KAP).

It is an innovative and modern tool for supporting clients who are struggling with treatment-resistant symptoms, stuck points, and repetitious life patterns.

Currently, Ketamine is the only FDA-legal psychedelic permitted for use in a clinical setting; hopefully this will soon change as legislation works to reclassify several psychedelic drugs. Ketamine has been used worldwide since 1970 and has been listed as an essential medicine by the World Health Organization since 1985. Over the course of its history, practitioners and medical researchers have come to understand ketamine’s psychedelic healing powers for mental health conditions and chronic pain.

Why consider Ketamine-Assisted Psychotherapy?

When years of therapy haven’t helped you move forward, Psychedelic Therapy can create transformational change where traditional therapy hasn’t worked.

How Ketamine Therapy works

The Experiential Effect

Ketamine dissociates the mind from the body, providing us with a glimpse into our unconscious without losing consciousness. Many refer to this as a higher consciousness.

The experience can change how we perceive the world and our present circumstances by offering a unique and objective view of oneself.

Psychedelic therapy has allowed many people to drastically shift their perspective to one that feels inherently true, allowing for psychedelic healing.

The Psychological Effect

Ketamine therapy can’t undo negative past experiences. It can, however, help us view our experiences without judgment.

The perceptual shift can move us out of feeling stuck in our troubles to seeing new possibilities and ways of being.

For many patients, the Ketamine experience can be a potent catalyst for change that might otherwise take months or years to access using more commonplace therapeutic techniques.

The Biological Effect

Ketamine is known for its antidepressant effect. Long-term depression can cause a loss of connections in our brains, called synapses, that facilitate nerve cell communication.

Research shows that within 24 hours of receiving the first dose of medically-supervised Ketamine, lost connections begin to regrow.

Regrowing and reactivating synapses can support the brain in shifting out of depression and helping you create new pathways that support the life you want to live.

You have many options for how you would like to use the medicine and each of these sessions varies in length.

Option 1: A 3-hour Medicine session at the Ko-Op at 1625 South Street in Philadelphia.

Option 2: A virtual session from the comfort of your own home. Where your therapist can log into your session anywhere from 1 to 3 hours.

Option 3: You use the medicine at home independently and meet with your therapist for ongoing weekly psychotherapy sessions.

Please note many people do a variety of these options throughout their treatment plan based on their personal situations and comfort levels with the medicine.

We use a Ketamine Lozenges/Troches (16-20% bioavailability). This means it is taken orally and allowed to dissolve in your mouth. Duration of action is 1-1.5 hours. The medicine is shipped to your house via our compounding pharmacy, and you bring it to each of your medicine sessions (if you are in person) or administer it yourself at home.

If choosing between clinicians is overwhelming, we can help! Request an appointment and choose “help me pick”, and we can help match you with a team member.

If you feel you may meet the criteria for our lower fee option, please contact us and tell us about your financial situation. We hear you and want to make sure individuals from all socioeconomic backgrounds have the opportunity to heal.
