Any medical condition that is not well managed would preclude you from treatment.  Uncontrolled high blood pressure, or any serious cardiac or respiratory conditions need to be disclosed to avoid complications.  Dr. Abreu will review all your conditions and medications with you when he goes over your patient health questionnaire.

Some patients have reported mild dissociative symptoms during their infusions which are short lived.  While not usually unpleasant some effects of floating, blurry visual changes,  and dizziness can occur.  These can be treated with other medications to make your infusion be a pleasant experience and not scary.
