Research evidence supports Reliefband-type acustimulation as a non-drug option for nausea and vomiting, with clinical trials showing reduced nausea and vomiting in some settings such as chemotherapy and postoperative nausea. The evidence is strongest for adjunctive use or specific procedural settings, while broader claims across all causes of nausea are less certain. It should be described conservatively as a wearable neuromodulation device rather than a guaranteed treatment.

The Reliefband is a wearable device designed to alleviate nausea and vomiting through non-invasive neuromodulation. It uses patented, FDA-cleared technology to stimulate the median nerve on the underside of the wrist. This stimulation sends signals through the nervous system to the brain, which then communicates with the stomach to reduce nausea symptoms.

This device is effective for various types of nausea, including those associated with motion sickness, migraines, anxiety, morning sickness, chemotherapy, and post-operative recovery. It offers a drug-free solution, making it suitable for individuals who prefer to avoid medication or experience side effects from traditional anti-nausea drugs.

Reliefband is fast-acting, providing relief within minutes, and its effects can last for several hours. It is safe for use by pregnant women and does not interfere with other medications. Originally developed for hospital use, it is now available over-the-counter, offering a clinically proven method to manage nausea in everyday settings.
