I2: Contraindications

  • Patients who have undergone surgery to cut the vagus nerve (cervical vagotomy);
  • Patients diagnosed with severe bradycardia;
  • Patients with a permanent (that cannot be removed before using Nurosym) implanted metallic or electronic device or jewellery at close proximity to the ear tragus;
  • Pregnant women.

Below are listed situations that are also contraindications unless the patient receives a different medical opinion on the device use by their medical doctor and is under the supervision of a medical doctor while using the device. If you fall under one of these categories, your doctor might advise whether, in your specific case, the device is safe to use, potentially following certain precautions or under specific supervision:

  • Patients with any active implanted device (including electronic and/or medical devices) e.g. cochlear implant, cerebral shunts, invasive vagus nerve stimulators, pacemakers2 or non-active but potentially interacting with the nervous system (e.g. metal implants);
  • Patients with known severe coronary disease or recent myocardial infarction (within 5 years);
  • Paediatric patients
  1. Pregnant women have not been evaluated in clinical studies.
  2. Both paediatric patients and patients with pacemakers have been enrolled in clinical studies with Parasym technology, and no device related adverse events or interferences have been observed so far in the clinical setting.
