What Is the Most Common Side Effect of TMS?

Transcranial magnetic stimulation (TMS) therapy is often beneficial for patients with depression who have not responded well to other treatments. For many, this FDA-cleared procedure relieves persistent symptoms by using magnetic pulses to change the chemistry of your brain.

When beginning any new medical treatment, it is important to understand the side effects. While most patients tolerate this procedure well, our team will describe the most common side effects of TMS so you can feel confident as you begin your personalized care plan.

How TMS Works

The goal of TMS therapy is to increase the presence of neurotransmitters such as serotonin and dopamine. Because these neurotransmitters affect mood, ensuring that they are at optimal levels may relieve your depression symptoms.

During treatment, magnetic pulses similar to those found in magnetic resonance imaging are introduced to your brain's left prefrontal cortex, the area responsible for mood regulation. These pulses become energy that activates cells and boosts neurotransmitter activity.

TMS therapy lasts five minutes, and because the common side effects are minimal, you can be in and out of our office within 15 minutes. The procedure does not require anesthesia or sedation, so you can continue your routine uninterrupted after the treatment.

Side Effects of TMS

Your care team at Cedar Park TMS will describe the side effects you may experience with this procedure. Typically, patients tolerate TMS well. The most common side effects are mild and include:

  • Headaches
  • Lightheadedness
  • Discomfort or pain in your scalp
  • Tingling or twitching of your facial muscles

These symptoms are often a result of your body adjusting to the treatment and will likely alleviate after several sessions. TMS treatment is customized to your needs, and your provider can adjust the level of stimulation if these side effects persist.

Less common side effects include seizures, mania, and hearing loss if your ears remain unprotected during treatment. If your provider thinks you may be at risk of these uncommon TMS side effects, they will suggest an alternate treatment.
