TMS is generally well tolerated. The most common side effects are usually mild and temporary and may include:

  • Headache
  • Scalp discomfort
  • Tingling or muscle movement around the face or scalp
  • Brief lightheadedness

These effects often become less noticeable as treatment continues. (nimh.nih.gov)

A seizure is a rare but serious risk depending on your medical history, medications, and other factors. If you are at risk, your clinician will recommend other treatment options.
