Letrozole stopped 2023 - severe urticaria side effect????

Hi I was initially diagnosed with stage 3, grade 3 left ductal carcinoma in January 2016.  After surgery, some of the chemo (not completed due to ill health and suffering with ME) and radiation I was given letrozole.  Side effects of severe pain, dizzyness and weight gain, as well as severe incontinence (feacal & urinary).  Stopped in 2023 after 8 years due to severity of incontinence. 

Two weeks after stopping I started with urticaria (initially under buttocks), then hands and wrists, now everywhere, even the side of my face/scalp and my eye was extremely sore.  Numerous visits to the doctors, taking fexofenadine (180mg) x 4 per day and also using hydrocortisone ointment, all to no avail.  I was referred to dermatology in 2024 and have been waiting ever since.  I believe it may be food related, however my reactions to numerous healthy foods are so bad that I cannot seem to target the offenders.  I am waiting for a referral to a food allergy service, but in the interim I was wondering if anyone has heard or had anything similar, or could give some advice.

My allergies that I have figured out are:

Dairy - in any form (cheese, milk, mayonnaise, cream)

gravy

curry

hummous/sesame seeds

some prepared meats, anything with additives

Could it be foods with estrogen in them?

I am currently living on salad, but feeling like a rabbit.

  • Hi Toppy

    I know the misery this can cause. Going down the food allergy/intolerance route by elimination without professional help is a diificult task. But with long waits for dermatology you dont seem to have much choice.

    Rice and lamb seem well tolerated by most. Like you dairy produce is a trigger for me. It seems it is the protein component that causes me grief. So I avoid all products containing whey skimmed milk. As well as dairy products.

    Have you thought of external factors that may affect you? For instance certain laundry detergents and conditioners can irritate and dry out the skin. As can many shampoos and soaps. Rough fabrics like wool. Sweat, strong sunshine etc.

    Try using fairy laundry detergent. Emulsifying bath oil instead of soap. Moisturising lotions like balneum or E45 anti itch cream. This may ease your symptoms. It is all a bit unscientific but Ive found it helps ease my symptoms.

  • Thank you for your kind words, I have tried most of these, shampoos and soaps are a problem, I use various prescribed creams on my legs and have been given steroid cream for the itch, as well as fexofenadine (4 x 180mg per day), but nothing touches it.  I have today received an appointment for September and am so thankful.
