Informed Consent for Ketamine Infusion | New Patient Intake
Since the early 1960s, the Food and Drug Administration (FDA) has required drugs used in the United States be both safe and effective. The label information on the container, in the package insert, in the Physician’s Desk Reference (PDR) and in any advertising can indicate a drug’s use only in certain “approved” doses and routes of administration for a particular condition. The use of a drug for a disease not listed on the label, or in a dose, or by a route not listed on the label is considered to be an “off- label” use of the drug. Physicians, based on their knowledge and on available current information, may use a drug for a use not indicated in the “approved” labeling if it seems reasonable or appropriate.
Ketamine has not been approved by the FDA to treat depression, bipolar disorder, or PTSD.
1. PROCEDURE – KETAMINE INFUSION THERAPY
An intravenous line (IV) will be started in an extremity so you can receive ketamine. Your blood pressure, heart rate, and oxygen saturation will all be monitored throughout the infusion under the supervision of a physician.
2. RISKS/SIDE EFFECTS
Risk of ketamine: Side effects normally depend on the dose and how quickly the injection is given. The dose being used is lower than anesthetic doses and will be given slowly over 40-60 minutes. These side effects often go away on their own.
Common side effects, greater than 1% and less than 10%:
-nausea and vomiting
-increased saliva production
-increased heart rate and blood pressure during the infusion -out of body experience during the infusion
-change in motor skills
These symptoms dissipate when the infusion is stopped. If they are severe, another medication such as a sedative can be used to treat the symptoms. You should not drive the day of an infusion and can resume driving the following day.
Uncommon side effects, greater than 0.1% and less than 1%:
-pain and redness in the injection site -Increased pressure in the eye
-jerky arm movements resembling a seizure
Rare side effects, greater than 0.01% and less than 0.1%:
-irregular or slow heart rate
-low blood pressure
-cystitis of the bladder: inflammation, ulcers, and fibrosis
-Ketamine can cause various symptoms including but not limited to flashbacks, hallucinations, feelings of unhappiness, restlessness, anxiety, insomnia and disorientation.
-There is a potential risk of dosing error or unknown drug interaction that may require medical intervention including intubation (putting in a breathing tube), or hospitalization.
-The risk of venipuncture may include temporary discomfort from the needle stick, bruising, or infection. Fainting may also occur.
-Risk of discomfort in answering questionnaires about your mental health and drug and alcohol use.
-Risk of other medications interacting with ketamine. It is very important that you disclose all medications, both prescription and over the counter, that you are taking.
-Ketamine may not help your depression, bipolar disorder, or PTSD
Ketamine has been associated with a decrease in depression, bipolar, and PTSD symptoms with results lasting for days to weeks to months. There is no way to predict how any single person will respond to ketamine infusion therapy. These effects may not be long lasting and will most likely require further infusions.
You must report any unusual symptoms or side effects at once to the medical staff on the day of the infusion, you should NOT engage in any of the following after the infusion:
-drinking alcohol or using drugs
-participating in activities which require you to rely on motor skills or memory
3. VOLUNTARY NATURE OF THE TREATMENT
You are free to choose to receive or not receive the ketamine infusion. Please tell the doctor if you do not wish to receive the infusion.
