Topical antibiotic medications, such as metronidazole, erythromycin and clindamycin, are effective against rosacea, according to MedicineNet. Oral antibiotics, such as tetracycline, minocycline and doxycycline, are also effective. Azelaic acid and brimodinine gel alleviate redness. Additionally, doctors sometimes prescribe the powerful acne medication isotretinoin to treat severe, resistant rosacea. Laser and intense pulse light treatments can reduce redness and noticeably improve skin complexion. Often, a combination of therapies provides the best results.
As sun exposure commonly aggravates rosacea redness, sufferers should avoid excessive sunlight and wear sunscreen and a wide-brimmed hat when outdoors, advises MedicineNet. Patients should wash their facial skin twice a day with a gentle, alcohol-free cleanser and avoid rubbing the face or overwashing, which can irritate the skin. Smoking, hot beverages, spicy foods and alcohol can cause facial flushing and worsen rosacea.
Although treatments are effective, there is no cure for rosacea as of 2015, according to Mayo Clinic. Symptoms include a persistent redness of the face, acne-like red bumps, and eye dryness or irritation. In rare cases, rosacea can cause an enlarged, bulbous nose. Risk factors for rosacea include fair skin, easy facial blushing and being between 30 and 50 years of age, states MedicineNet. Rosacea is not contagious or infectious.
