What’s New in Rosacea

Rosacea can sometimes be quite severe. Most patients improve with creams and sometimes oral antibiotics (especially patients with eye irritation). However, I see some patients that fail standard treatment. Rosacea is multifactorial (ie, each patient has a likely different reason to have rosacea) but there has been recent appreciation of the role that skin mites (Demodex folliculoum) may play in the disease, especially in those that fail standard treatment. There are different ways to treat these mites. The antibiotics dermatologists prescribe have some efficacy against them (antibiotics have anti-inflammatory and anti-mite effects in addition to their traditional anti-bacterial effects). To target the mites, I currently use a pill called ivermectin and have had success in some severe patients who failed standard treatment. However, in general, it is preferred to use a cream to avoid systemic side effects. Ivermectin 1% cream has completed phase 3 trials with ~40% of patients becoming clear or almost clear after 12 weeks of treatment. In addition, the creams were tolerated well with only 2.5% of patients having significant irritation. It is a greatly appreciated addition to our armamentarium although likely will not be available until 2015. There is a 0.5% lotion available that is approved for head lice, but is unlikely to be as effective as the upcoming 1% cream.

If you have rosacea, I look forward to seeing you to discuss your options. Please make an appointment for a dermatology consultation at (626) 331-6411.
