Can biologics help control my prurigo nodularis and itching?

Question

Hello doctor,

I am a 45-year-old woman with intensely itchy skin nodules on my arms and legs for the past year. Scratching makes them worse, and the itching is so severe that it disrupts my sleep. Topical creams give only temporary relief. My dermatologist mentioned prurigo nodularis and said it may be linked to immune system dysfunction.

Are there advanced therapies, like biologics, available for this condition?
Can it be permanently cured, or only controlled?

Kindly help.

Hello,

Welcome to icliniq.com.

I can truly understand how exhausting and distressing it can be to live with intensely itchy nodules for such a long time, especially when they disturb your sleep and daily comfort.

Prurigo nodularis has a link between the immune system and the nerve pathway that causes severe itching. The main aim is to break the itch cycle. Prurigo nodularis is a chronic condition, so the goal of treatment is long-term control rather than a permanent cure.

Currently, targeted biologic therapies, such as Dupilumab and Nemolizumab, specifically block itch-related immune signals and are now easily available. They have shown remarkable improvement in itch severity, sleep quality, and gradual flattening of nodules in many patients who did not respond to standard treatments. If topical medications are not working for you, you can go for biologic therapy. You can achieve long-term remission and a dramatic reduction in symptoms, but intermittent maintenance may be needed to prevent flares in the future.

For general tips, try to moisturise the nodules with bland emollients when you experience itching; it will help. Trim your nails, try to use a microfiber cloth when you want to itch instead of using your nails, and you can also go for intralesional steroids in large nodules before considering biologic therapy.

I hope you are satisfied with my answer. For further queries, you can consult me at iCliniq.

Thank you.
