Initially the redness may come and go, but left untreated it tends to become more pronounced and permanent, and tiny visible blood vessels may appear. As the disease progresses, facial swelling may occur and bumps and pimples often develop. To bring rosacea under immediate control, physicians typically prescribe both oral and topical antibiotics. In addition to medical therapy, rosacea patients are advised to avoid environmental and lifestyle factors that may aggravate their individual conditions. The most common rosacea tripwires include sun exposure, emotional stress, hot weather, alcoholic beverages, spicy foods, strenuous exercise, hot drinks, cold weather and wind.
Topical metronidazole maintains remissions of rosacea.
