I have prurigo nodularis at 34. Will pregnancy affect it?

Question

Hello doctor,

I am a 34-year-old woman recently diagnosed with prurigo nodularis. The constant itching and nodules are very distressing, and I have noticed flare-ups tend to worsen around my menstrual cycle, which makes me wonder if hormones are influencing my condition.

I also have concerns about future pregnancy and fertility.

How safe are prurigo nodularis medications if I want to conceive soon?
Could pregnancy improve or worsen my symptoms?
Is it safe to undergo IVF (In vitro fertilization) while having active lesions, or might the stress and hormone injections make things worse?
I am also unsure about hormonal birth control, whether pills or IUDs (Intrauterine devices) aggravate prurigo nodularis, and are there safer options?
I have read that skin conditions sometimes flare during menopause. Should I expect this condition to remain lifelong?
Lastly, what topical or systemic treatments are considered safe for women planning pregnancy?

Kindly help.

Hello,

Welcome to icliniq.com.

I have read your query and can understand your concern.

Prurigo nodularis can be very distressing, and it is understandable to worry about how hormones and future pregnancy might affect your condition. Some women do notice flare-ups around their menstrual cycle, suggesting that hormonal changes may influence immune response and itching, though the exact mechanism is not fully understood. Stress and hormonal fluctuations can both aggravate symptoms.

Probable causes: Chronic prurigo nodularis with hormonal fluctuations around periods worsens inflammation and itch.

Investigations to consider:

Basic hormone panel that includes `(thyroid-stimulating hormone), prolactin, estrogen, and progesterone if cycles are irregular.
Allergy or autoimmune workup only if your dermatologist suspects an underlying trigger.
Hemoglobin and iron studies, since chronic itch can sometimes be linked to anemia.

Differential diagnosis:

Atopic dermatitis with nodular changes.
Chronic urticaria.
Lichen simplex chronicus.

Probable diagnosis: Hormone-sensitive prurigo nodularis.

Treatment plan:

If planning pregnancy soon: Most systemic agents for PN (immunosuppressants, biologics) are not safe. Safer options include topical emollients, corticosteroids, menthol, or calamine.
Phototherapy: Narrow-band UVB can be considered and is relatively safe during pregnancy.
Pregnancy impact: Symptoms may improve, worsen, or stay the same—responses are unpredictable. IVF is not contraindicated, but hormonal injections and stress may trigger flares.
Contraception: Hormonal IUDs or pills can sometimes worsen skin conditions if you already notice cycle-related flares. A copper IUD (non-hormonal) may be a safer option.
Menopause: The condition often persists long-term, but reduced hormonal cycling may bring steadier control. PN is generally managed rather than cured.

Follow-up:Before conceiving, review all current medications with your dermatologist. Some, like Ciclosporin, Methotrexate, or Dupilumab, must be stopped well in advance. If you share your present treatment, I can guide you on safety in pregnancy.

Preventive measures:

Keep skin moisturized daily.
Avoid scratching (short nails, night-time antihistamines if advised).
Manage stress, as anxiety often worsens the itch.

I hope this answers your query.

Please let me know if I can assist you further.

Thank you.
