Retail health care practitioners can treat patients with rosacea in 10 easy steps.
Rosacea, an incurable chronic condition, affects more than 16 million Americans and usually presents in adulthood.1Common signs include central facial erythema, flushing, and inflammatory lesions (papules, pustules). Rosacea has inflammatory, neural, and vascular components.2
Retail health care practitioners can treat patients with rosacea in these 10 easy steps:
1. Set realistic expectations.Researchers have not identified rosacea’s underlying cause. Symptom frequency and severity are patient specific and can vary over time. Successful symptom management involves avoiding triggers, using gentle skin care products, and, often, prescription medication.3
2. Raise resource and support system awareness.Most patients with rosacea experience depression, embarrassment, social anxiety, and stress. Emotional stress can trigger outbreaks, creating a cycle detrimental to mental health.4Cognitive behavioral therapy relieves anxiety, a fear of blushing, and stress.5Social support forums and groups also help patients with rosacea manage the psychological effects. Table 1 lists patient-friendly resources.
3.Identify specific triggers.Recognizing triggers (see Figure 16) is essential to avoid exacerbation. Sun exposure is the most common trigger, so advise patients to wear protective clothing and sunscreen every day.7Long-term topical beta-blockers, corticosteroids, niacin, and vasodilator scan also trigger flare-ups.8
Recommend that patients keep a diary or take daily selfies, noting what activities, diet, and exposures contribute to symptom exacerbations. The National Rosacea Society offers a free trigger diary (rosacea.org).6
4. Stress behavior modifications, especially sun avoidance.Sun exposure can worsen rosacea even in those with dark skin, so all patients must wear sunscreen year round. Recommend broad-spectrum sunscreen with a sun protection factor of 30+ and ingredients that reflect ultraviolet rays, such as titanium oxide and zinc oxide.9
Patients should avoid physical activities (bike riding, football, horseback riding, etc) that cause facial friction or require headgear. Although they need to remove facial dirt and oil, patients also must limit showering to once or twice daily with lukewarm water and mild cleansers. Immediately after showering, they can apply unscented emollients or oils.10
5. Determine the patient’s top treatment priority.Most topical rosacea treatments are available in various forms (see Figure 211,12).11Ask patients what features they dislike or like to improve adherence. Ask what they have tried in the past, recommending OTC products first and then prescribing if necessary. Undertreatment is common, so do not shy away from prescription products.12
Table 23,13describes OTC product characteristics.
7. Offer an everyday facial skin care routine example, such as this one3,9,11:
8. Manage expectations for topical prescriptions.Select prescription topicals based on patient-specific subtypes and most bothersome symptoms. Azelaic acid and metronidazole address papulopustular lesions. Common adverse effects include burning, itching, skin irritation, and stinging. This regimen takes at least 6 to 8 weeks for a therapeutic response; azelaic acid is slightly more rapid acting.2Advise patients that they will use topical agents for life.7
Brimonidine gel lessens persistent bothersome redness between flare-ups within 30 to 60 minutes. Rebound or worsening redness is a potential adverse effect, along with burning, contact dermatitis, and flushing. Assess efficacy in 2 to 4 weeks.2
9. Consider oral anti-inflammatory antibiotics. Patients with moderate to severe rosacea can take an anti-inflammatory dose of modified-release doxycycline in addition to, or instead of, topical therapies. For flare-ups, use doxycycline (40 mg/d) for 10 to 14 days and up to 9 months for maintenance. Reserve oral antibiotic doses of doxycycline (50 to 200 mg/d) for poor responders to low- dose antibiotic and topical regimens.2Inform patients that antibiotics for rosacea will not treat bacterial infections and cannot be used during pregnancy. Doxycycline can cause adverse gastrointestinal effects and sun sensitivity.14
10. Step-up treatment for refractory/severe cases.Isotretinoin is an option for refractory/severe cases, but it is contraindicated during pregnancy and requires frequent lab monitoring.2Some patients may opt for modalities such as laser light treatment, but the cost limits its accessibility.15Inform patients interested in complementary or alternative medicine options about the limited efficacy, and recommend sticking with FDA-approved products.13
