Isotretinoin (also known as Roaccutane or Accutane), is best known for treating severe acne, it can also be an extremely effective option for carefully selected patients with severe or treatment-resistant rosacea.
Isotretinoin is not usually a first-line treatment for rosacea. Most patients achieve good control with a combination of trigger avoidance, gentle skincare, topical treatments such as Ivermectin and Oral Antibiotics. However, when these measures fail, low-dose isotretinoin may provide long-lasting improvement.
Isotretinoin reduces the size and activity of the sebaceous glands, decreases inflammation within the skin. The result is often a significant long-lasting reduction in inflammatory papules and pustules, together with an improvement in persistent redness.
Isotretinoin is particularly useful in these situations:
- Severe papulopustular rosacea: Patients with frequent outbreaks of red bumps and pustules despite standard therapy.
- Early phymatous rosacea: Low-dose isotretinoin may help slow the progression of skin thickening and rhinophyma, although established tissue overgrowth usually requires Ablative Laser.
In contrast to acne treatment, rosacea is often managed with lower doses of isotretinoin.
The most common side effects are dryness of the lips, skin, and eyes, mood disturbance (anxiety or depression). muscle aches and increased sensitivity to the sun. Blood tests are required to monitor liver function and blood lipids during treatment.
Isotretinoin causes severe birth defects and women who could become pregnant must use highly effective contraception during treatment and for at least a month after stopping the medication.
Although isotretinoin can be effective, it is not suitable for everyone and should only be prescribed after careful in-person assessment by a dermatologist. When used appropriately, it can provide substantial and long-lasting improvement in some of the most difficult forms of rosacea.
