TMS is a generally safe procedure with over two decades of intense clinical and scientific research behind it. In 10,000 treatments during clinical trials, the most common side effects is mild to moderate scalp discomfort and mild headaches, both of which usually went away in the first week of treatments. In a very small percentage of instances there were reports of acute memory loss, minimal cognition interruption, facial twitching, and seizures. These side effects were acute and TMS showed no long-term issues.

No, the most common side effect related to treatment was scalp discomfort during treatment sessions. This side effect was generally mild to moderate, and occurred less frequently after the first week of treatment.

If necessary, you can treat this discomfort with an over-the-counter analgesic. If these side effects persist, your doctor can temporarily reduce the strength of the magnetic field pulses being administered in order to make treatment more comfortable.
