Unlike a conventional antidepressant, ketamine causes minimal side effects — all of which are short-term, so patients enjoy better quality relief without the additional challenges of weight gain, loss of libido, dry mouth and other undesirable side effects often associated with antidepressant medications. There are no known long-term side effects of ketamine when used in a clinical setting. (Used illicitly on the street at high doses for prolonged periods of time, there can be serious side effects, the most common of which is cystitis, severe inflammation of the bladder lining.)
While ketamine for depression has been researched thoroughly for more than 20 years, ketamine has been used for sedation and other indications at much higher doses for over 60 years and has proven itself to be a very safe medicine — so safe that it’s the preferred choice for pediatric cases.
The most common short-term ketamine side effects are:
- Dissociation (a floaty feeling, confusion, sensory illusions)
- Feeling tired or groggy following the infusion
- Mild nausea
- Dizziness
- Mild elevations of heart rate and blood pressure (which are continuously monitored and treated as needed during your infusion)
Most ketamine treatment side effects are temporary and gradually subside following treatment. Typically, any side effects completely disappear after a full night of sleep.
If you are concerned about potential short-term side effects, you can ask one of our practitioners for tips on minimizing or preventing them. For example, antiemetics (medication for nausea and vomiting) may be helpful for IV ketamine therapy patients who are prone to nausea.
If any of the side effects of ketamine infusion therapy persist or become bothersome, or you have questions, we are always available to discuss and assist. Minor changes in other bodily systems may sometimes occur during an infusion. For instance, the blood pressure, pulse rate or heart rate may increase. These changes in vital signs usually normalize without intervention soon after an infusion is completed, if not sooner. Medication may sometimes be used to minimize or prevent these side effects.
