The efficacy of ketamine is certain. The question of safety depends, as always, on the patient’s clinical assessment. It won’t be right for every patient, even as it positively changes lives for other patients. So far, no adverse effects have been discovered. For low doses of ketamine, side effects tend to be minor. They may include disorientation, dizziness, feelings of detachment, nausea, fatigue, increased heart rate, and heightened blood pressure. Our clinic is equipped to handle changes in patients’ vital signs and other side effects, should they occur.
