What's New in Rosacea

What's new in Rosacea

There is a new topical therapy for rosacea called Rhofade (oxymetazoline) cream. While the FDA approved it in January, it has only been available at pharmacies recently. It is best used for the redness of rosacea (there are plenty of other medications for the acne-like bumps that are treated separately). It is a cream applied once daily that works by constricting blood vessels (technically called an alpha adrenergic agonist). It seems to be an improvement over a similar product called Mirvaso as it seems to cause less rebound (when a medication constricting the blood vessels wears off, there is potential that blood will rush into the area faster than before, causing increased redness and burning sensations. Iíve had some patients experience that with Mirvaso. Anecdotally, it seems much rarer with Rhofade).

I am not aware of the full clinical trial data being published. That being said, the FDA product insert summarizes that 489 study subjects were treated over 4 weeks. A separate up to 1 year clinical trial enrolled 440 subjects. Efficacy was good. However, the redness rarely completely resolved. Adverse reactions were quite low with 3% or fewer subjects experiencing rashes, flares, itching, redness, and discomfort.

As with most new products, it is only available as a brand name. No generic is available. Thus, the usual caveats that the copay may be high, it might be completely rejected by insurance, or I may recommend using a specialty pharmacy that is experienced in brand name medication insurance paperwork for a higher success rate. I have zero financial ties with any of these specialty pharmacies.

If you have rosacea or other skin issues, please make an appointment for dermatology consultation at (626) 331-6411 to discuss your options.
