Use of #beta-blockers for #rosacea-associated facial erythema and flushing: A systematic review and update on proposed mode of action

Flushing and erythema are frequent skin symptoms in rosacea. Because their adequate treatment remains a clinical challenge, new treatment options are explored, such as oral β-blockers..

..Nine studies evaluating the use of carvedilol, propranolol, nadolol, and β-blockers in general were included. Articles studying carvedilol and propranolol showed a large reduction of erythema and flushing during treatment with a rapid onset of symptom control. Bradycardia and hypotension were the most commonly described adverse events.

Limitations
Most studies had a retrospective design with a small sample size, and outcome measurement was often subjective.

Conclusions
Oral β-blockers could be an effective treatment option for patients with rosacea with facial erythema and flushing that does not respond to conventional therapy. Larger prospective trials with objective outcome assessment are needed to validate the promising results of these studies.
