Transcranial Magnetic Stimulation (TMS) has emerged as a breakthrough treatment option for people struggling with depression symptoms and other mental health conditions. With FDA approval and increasing use in clinics worldwide, TMS therapy offers hope for those who have not found relief with traditional medications or electroconvulsive therapy (ECT).
However, as with any medical procedure, understanding and managing side effects during your weeks of treatment is crucial for a successful outcome. This guide will help you prepare for TMS treatment, recognize potential side effects, and provide actionable tips for a smoother experience.

What is TMS Therapy?
TMS therapy uses magnetic pulses delivered through magnetic coils placed against your scalp. These pulses generate a magnetic field that stimulates specific areas of the brain involved in mood regulation.
Unlike ECT, TMS does not require anesthesia and is considered non-invasive. Each treatment session typically lasts 20–40 minutes, and patients remain awake and alert throughout. TMS is primarily used for treating depression, but is also being explored for other mental health conditions such as anxiety and obsessive-compulsive disorder.
How TMS Works
- Magnetic Coils: Positioned on the scalp, these deliver targeted magnetic pulses.
- Magnetic Field: The pulses create a magnetic field that penetrates the skull and stimulates brain cells.
- FDA Approval: The Food and Drug Administration has approved TMS for major depressive disorder and other indications after rigorous clinical trials.
- Deep TMS: A newer form, deep TMS, uses specialized coils to reach deeper brain structures, expanding its potential benefits.
Common Side Effects of TMS
TMS therapy is generally well-tolerated, but some patients experience mild side effects. Knowing what to expect can help you manage them effectively. Common TMS side effects include:
- Scalp Discomfort: A tingling or tapping sensation at the treatment site is common, especially during the first few sessions.
- Headache: Some patients report mild to moderate headaches after a TMS session.
- Lightheadedness or Fatigue: Feeling tired or slightly dizzy is possible but usually resolves quickly.
What Causes These Side Effects?
The magnetic pulses stimulate nerves and muscles in the scalp, leading to temporary discomfort. The clicking sound from the device can also be startling, but ear protection helps reduce this effect.
Most side effects are mild and diminish as your body adjusts to the treatment. Scalp discomfort and headaches often improve after the first week of sessions.
Rare Side Effects of TMS
While TMS is considered safe, rare side effects can occur. Understanding these risks helps you make informed decisions about your treatment. Uncommon but possible side effects include:
- Seizures: Extremely rare, especially when safety guidelines are followed.
- Hearing Issues: The loud clicking sound may cause temporary hearing changes if ear protection is not used.
- Mood Swings or Mania: Patients with bipolar disorder may experience mood elevation.
- Cognitive Changes: Some report mild memory or concentration issues, but these are uncommon.
Effective Strategies for Managing TMS Side Effects
Successfully managing TMS side effects requires a proactive approach throughout your treatment journey. Most side effects are manageable with simple strategies. Here’s how to handle them:
- For Scalp Discomfort: Over-the-counter pain relievers like acetaminophen can help. Ask your provider about adjusting the magnetic coil position or intensity.
- For Headaches: Hydrate well before and after each treatment session. Use mild pain relief as needed.
- For Clicking Sound: Always wear ear protection during each TMS session.
- For Tapping Sensation: Communicate with your technician if the tapping becomes uncomfortable. Adjustments can usually be made.
During treatment, focus on relaxation techniques such as deep breathing or progressive muscle relaxation. Many patients find it helpful to listen to calming music or guided meditations during their TMS session.
After treatment, allow yourself time to rest if needed. Stay hydrated and avoid strenuous activities immediately following treatment.
When To Contact Your Healthcare Provider
While most side effects are manageable, certain symptoms require immediate medical attention. Contact your healthcare provider immediately if you experience:
- Seizure-like activity
- Severe headaches that don’t respond to pain relievers
- Significant mood changes, including suicidal thoughts
- Severe scalp pain
- Other symptoms that interfere with daily activities
How to Prepare for TMS Therapy
Preparation is key to maximizing the benefits of your TMS treatment and minimizing any side effects. Here’s how to get ready:
1. Medical Evaluation
Before starting TMS, your provider will conduct a thorough assessment. This includes reviewing your medical history, current medications, and previous treatments. Be honest about any history of seizures or neurological issues, as these are important for your safety.
2. Discuss Medications
Some medications can influence the risk of side effects during TMS sessions. Inform your provider about all prescription and over-the-counter drugs you take.
3. Set Realistic Expectations
TMS is not a quick fix. Most patients require several weeks of treatment, often five sessions per week. Improvement in depression symptoms may take time, so patience is essential.
4. Comfort Tips for Your First TMS Session
- Wear comfortable clothing.
- Eat a light meal beforehand.
- Remove any metallic objects from your head or neck.
- Bring earplugs to reduce the clicking sound produced by the magnetic coils.
5. Questions to Ask Your Provider
- What side effects should I expect?
- How many treatment sessions will I need?
- What happens if I experience scalp discomfort or other issues?
Finding TMS Treatment
If you’re thinking about trying TMS therapy, speak with a qualified healthcare provider to see if it’s the right fit for your needs. With proper guidance and support, TMS can be a powerful step toward better mental health and overall well-being.
