Spicy foods, alcohol, and hot beverages were traditionally thought to trigger flushing in patients with rosacea. However, most evidence does not support dietary factors playing a central role in the pathogenesis. Moreover, certain medications, such as amiodarone, topical steroids, nasal steroids, and high doses of vitamins B-6 and B-12, may cause flares for patients with rosacea.
