Vagus Nerve Stimulation for Rosacea

This trial explores a new method to manage rosacea, a skin condition that causes redness and flushing. It uses a device called transauricular vagus nerve stimulation (taVNS) to determine if it reduces these symptoms over four weeks. Individuals with rosacea who experience moderate to severe redness and can maintain their current treatment routine may be suitable candidates. The trial seeks to determine if the benefits persist for an additional four weeks after stopping the treatment. As an unphased trial, this study provides a unique opportunity to investigate innovative treatments for rosacea.

You can continue your current rosacea medications, but you cannot make any changes to them during the study. If you've used certain medications like brimonidine, oxymetazoline, beta-blockers, anticholinergics, or vagal-modulating drugs in the past 4 weeks, you may not be eligible to participate.

Studies have shown that transauricular vagus nerve stimulation (taVNS) is generally well-tolerated. Research indicates that side effects are rare. In one review, only 5.6% of participants using taVNS experienced side effects, most of which were minor.

Unlike the standard treatments for rosacea, which typically include topical creams, oral antibiotics, and laser therapy, transauricular vagus nerve stimulation (taVNS) offers a novel approach by targeting the nervous system. Researchers are excited about taVNS because it uses a non-invasive method to stimulate the vagus nerve through the ear, potentially reducing inflammation associated with rosacea. This mechanism is different from conventional treatments and could offer a new, drug-free option for managing symptoms.

Research has shown that transaricular vagus nerve stimulation (taVNS), which participants in this trial will receive, can help reduce rosacea symptoms such as facial redness and flushing. In studies, individuals who received taVNS experienced noticeable improvements in these symptoms compared to those who did not receive the treatment. Participants also reported reduced anxiety, which often accompanies rosacea. This treatment has also proven beneficial for other conditions like migraines and depression, suggesting it may help calm the nervous system. Overall, these findings indicate that taVNS could be a promising option for managing rosacea symptoms.¹²³⁴⁵
