Yes. Vagustim, the earsets, and the Vagustim gel should be kept away from pets and animals, and away from children.
Vagustim is not intended for use by individuals under the age of 18. For elderly, pediatric, or differently-abled users, a special warning should be given by the person handling the product before use — and if someone needs help with setup, placement, or safe use, a responsible adult or caregiver should assist.
Choking hazard
Vagustim and its accessories are not intended to be used near the mouth, or to be ingested or swallowed. Extra attention must also be paid to the long cables: make sure they do not become entangled, and keep any part of the product away from the mouth.
If an earset part enters the ear canal
Do not try to remove it yourself. Contact your doctor.
