Main Causes of Ketamine Side Effects
Ketamine works differently from many traditional antidepressants. It acts on glutamate, one of the brain’s main chemical messengers, which is part of why it can work quickly. That same action also explains many of its side effects.
How Ketamine Acts on the Brain
Ketamine blocks a receptor called NMDA. This shift in brain signaling can create the dissociative, dreamlike feelings many people describe. These sensations usually peak during the session and ease as the medication wears off.
Dose and Delivery
The amount of ketamine, how quickly it is given, and the way it is delivered can all influence how strongly side effects show up. Two people receiving ketamine may have very different experiences.
Individual Health Factors
Your overall health, blood pressure, sensitivity to medications, and other prescriptions can shape how your body responds. Your emotional state on the day of treatment can also color the experience.
Frequency and Long-Term Use
Repeated or frequent exposure, particularly outside of a supervised medical setting, has been linked to bladder problems and dependence. This is one reason a structured plan and open communication with your care team matter so much.
