Allergic to antihistamines????? ANY INFO MUCH APPRECIATED

Hello Laura, Sorry to hear about your ongoing hive and antihistmine situation. My daughter is  8 yrs old and dealing with similar symptoms for the last 3yrs.  Her GP told us her hives should last 6 wks. Fortunately they are not constant, and only sometimes itch. They typically go away within hrs., she's tried allegra, claritin, zyrtec and benadryl to block the histamine and They all cause severe allergic reactions that typically last 4-5hrs. Her entire torso becomes one big hive, she feels like she's on fire!  We are on our 3rd allergist. We've been told she has dermagraphism (writing on the skin) coupled with physical urticarias. Her triggers are sun, heat, cold, ocean water and cold pool water. She's had a biopsy at my dermotologist which came back negative for mastocytosis urticaria pigmentosa, blood work has also confirmed that her tryptase levels are low. We are back at square 1 again!! She's also having mild allergic reactions to ibuprofin and tylenol. Which in years past have never been a problem. Her only relief to the itch is calamine lotion!!

We've heard not many people suffer from these urticarias and they usually subside or go away within 3 to 5 yrs!

Her current allergist has her on a probiotic to clear her system of any bad bacteria. He's checking all her meds that caused a reaction for a common ingredient that she may be allergic to!!

Good luck to you and keep me posted!!

Kathy

 

I am so sorry for you, I have had it for two years plus..started with Ibuprofen ..I still have it everyday but a pause for a few days in between.taking Hydroxozine , and cream...thinking of Zolaft..so sorry, it is a horrible thing..

Hi Kathy & Soo,

I really hoped to have good news to tell you following my appointment with the immunologist but sadly not. For the third time this year I've been admitted to A&E with the start of anaphylaxis.

Not one day since December has gone by without me having at least one body part covered in hives/angioedema 😢

I've been trying a low histamine diet but it doesn't stop me taking 3 antihistamines a day to control the burning and itching (it doesn't even stop the hives).

If I could afford to trial the Daosin tablets I would, they control the histamine in your gut which sometimes helps if your overproducing histamine, might be something to look into, if your hives seem troublesome after eating.

I'm taking Fexofenadine, Zirtek (certrizine) & Piriton - so two H2 & a H1 antihistamine.

I've had an allergy to Aspirin and Ibuprofen since I was 5 - that was an anaphylaxis reaction.

UK GPs seem reluctant to try too much, hoping the hives will run their course but 6 months in I feel worn out, constantly drained and my skin is suffering - what a joy lol

I hope your little ones hives settle, as an adult it's a nightmare but for children I suspect it's torture at least I can try my best to explain and treat symptoms but for children it's difficult to even explain.

Good luck both of you xxx

I have the same condition ( i think worst) i feel so helpless.

i have asthma and Im allergic to almost all the medicine I try to take.

recently tried neozep for my runny nose, i developed rashes (hives).

i am also allergic to my own antiasthma pills and nebules. ;(

antihistamines makes my allergy worst, so im on hypo allerginic diet (boiled veges  and fruits ) 

everything was normal growing up, i could eat and take any meds. until I finished college, i developed brochial asthma (hereditary) then allergy to almost everything ( sun, dust, fur, food, heat, cold, medicines)  i could stay in the sun but limited time. No doctor wants to handle my case, they are allscared to give me medicine, I cant even have my molar teeth extracted... 

 

Antihistamines are a funny old thing. Like most of us I tried all the different types including the typical fexofenadine. And like many of us under instruction from the immunologist I was taking a lot of tham and alternating the fexo with any other one. My pill intake including vitamin D and steroids and hydroxychloroquine and montelukast as well as the antihistamines was getting insane. It seemed to work for a few days and then despite the level of medication it would come roaring back.

Finally I stopped taking everything, except the steroids when I really needed them and fianlly it cleared up.

But I also made sure my teeth were all sorted... which may sound utterly insane but I had always had a feeling it was realted to poor teeth. And the immunologist said any site where there may be an inflamatory process out of control can trigger it. And having had two teeth recrowned I also had a crown come out with all the super structure under it and found it had been rotten under the crown base for possibly years.

The only advice I think is solid is, take no anti inflamatories (ibuprofen etc), drink no alcohol and get to see an immunologist not a dermatologist. This is not a skin condition it just manafests on the skin. To relieve the itching if you have any, use best quality organic cider vinegar... and have it handy in a spray so if it itches at night say, spray it on instead of scratching. I would also try and get steroids from your GP, they were the only thing which really worked when needed.

 

I thought I was the only person with this problem I cannot take antihistamines they give me hives as well. I suffer from seasonal allergies I feel at a lost of what I should do never can seem to get any help or suggestions from the Dr.'s so I just suffer till frost comes.

I've always had a problem with antihistamines. Zyrtec and claritan body cramping and trouble swallowing. Allegra, nervous and trouble swallowing. Clortromitron severe tachycardia. I'm on benedryl now which speeds up my heart and causes leg cramping. I'm on valium do spine problem so it counteracts this. Im allergic to corn. I'm alot of medicines. You could be reacting from inactive ingredients.
