Urticaria Pigmentosa Adults
How likely is it for someone to have urticaria pigmentosa and cold urticaria? And should I be more worried about symptoms with my son having both?
Urticaria pigmentosa: Urticaria pigmentosa is arare genetic mutation of mastocytosis of the skin. Symptoms can be mild (flushing and hives that require no treatment), moderate (diarrhea, tachycardia, nausea/vomiting, headache, and fainting), or life-threatening (vascular collapse requiring emergency treatment and hospitalization). Usually cold urticaria is annoying but not serious though in rare case it can be. The coi.
You are lucky: You should see an allergist/immunologist and/or dermatologist. As you live in Denver, go either to National Jewish Health at 1400 Jackson or to the University of Colorado Medical Center in Aurora, at what used to be Fitzimmons Army Medical Centers many years ago.
My six month old son has urticaria pigmentosa. Are there any safe topical medications that I can use on him?
Urticaria pigmentosa: Your son has an elevated number of mast cells in the skin. When you rub the skin, the skin will make hives, because the mast cells release histamine. It doesn't mean that topical medications pose any problem to him, just that when you apply them, you need to do so very lightly, to avoid setting off histamine release. Your doctor can prescribe topical antihistamines but oral ones are really needed.See 1 more doctor answer
Is it ok to use both cetirizine and fexonadine alternately to my 16 month old son? He has urticaria pigmentosa
That is fine.: With itching or flushing due to diffuse cutaneous involvement or urticaria pigmentosa, non-sedating antihistamines may be administered on a scheduled or as-needed basis, depending upon symptom frequency. Sedating antihistamines can be added for refractory symptoms. Consult with prescribing physician if symptoms are not well controlled.
How likely is it to develop anaphylaxis if you had none and you're a young adult? There is long & recent history of rhinitis and urticaria however.
Antihistamines: Over-the-counter non-sedating antihistamines like Allegra, Claritin, or Zyrtec are helpful for persistent hives while sedating antihistamine like Benadryl (diphenhydramine) can be helpful for acute hives. If you have persistent hive reactions consider being seen by an Allergist for further treatment and evaluation. There are many triggers of hives so determining right trigger is important moving forward.
Hives: Urticaria is simply the medical term for hives. It can be classified as acute (short term) or chronic (greater than ~6 weeks). Acute urticaria could be due to (but not limited) to allergic or infectious in nature. In contrast, chronic daily hives are not typically due to an external allergy.See 2 more doctor answers
See below: You may want to consider being tested for celiac disease---there are cases of chronic urticara associated with it.
Urticaria: Your doctor can help you answer your question by examining your skin lesions
No: Urticaria (hives) won't kill. Just don't take both hands off the steering wheel to scratch. Anaphylaxis is a much more severe allergic reaction that includes hives with laryngospasm (a choked off windpipe) or shock. These things can kill you but anaphylaxis is quite uncommon compared to hives.See 1 more doctor answer
Find & Control: Find the cause, when possible. Control the symptoms. There are many things which cause urticaria, and sometimes urticaria can be auto-immune (ie due to your own body's production of antibodies). An allergist can help you identify the cause, when possible, either something as simple as your soap, or watch, or a food, or more complicated like a serious medical problem.
There aren't any: There are no specific topical treatments such as creams, ointments etc that are effective in treating hives. Typically the hives are too widespread to make it practical to apply creams, etc. Oral antihistamines are the first treatment for hives.
Usually not: Solar urticaria normally results in hives after sun exposure that is often accompanied with itching, burning, and rarely pain. Severe attacks are RARE but can manifest with malaise, light-headedness, nausea, bronchospasm, and/or syncope. If you have solar urticaria, I recommend taking an oral antihistamine about an hour before going outdoors and protecting your skin when outside.
Any allergy can.: Urticaria (hives) is due to true allergy only 10% of the time. Any type of allergy can cause the skin rash. Foods & drugs are the most common. Other causes can be physical (direct pressure on the skin; cold; change in skin temperature) or underlying diseases like thyroid or auto-immune disorders, infections, cancer, etc. Urticaria that lasts up tp 4 weeks is considered acute. Longer is chronic.See 1 more doctor answer
