Can you answer these questions (Ask a question):

  • Has anyone with itp been offered or receivedimmunology for severe allergy to grass pollens? if so what was the outcome? our immunologist knows of no-one with itp receiving immunologgy and is fearful.
    Discovered low platelets when had a severe allergic reaction to hayfever & subsequent trip to A&E
    Hospital Allergy Dr's - Grass Pollens - off the scales. His (my son's) low platelets are caused by antibodies attacking platelets (autoimmune thrombocytopenia). No other cause for ITP found so presumed virus or could also be the inflamatory allergic reaction.
    Immunologist scared to give even grazax (orally taken - one a day) and def not quattro injection immunology. Immunologist has said he know of not one single case of immunology and the outcomes on platelett count and ITP and so will not give. has anyone had both immunology who also has ITP?????
    My son has now been diagnosed with ITP for 7 months and is very frustrated and we are dreading this new hayfever season, eventhough the immunologist has upped the fexofenadine to start in march.. We are UK. He is on all treatments for hayfever, eye drops, nasal inhalers, sinus rinse, prventers (prevalin). He has been given prednisolone for 1st week after visit to A&E but none since
  • Is fexotenadine hydrochloride an amphetamine
    just want to know what category this drug comes under before taking same
  • Seizure after an epipen injection (1 answer)
    I am allergic to EVERYTHING, so I usually pre-game with benadryl and wait out the uncomfortable side effects, but this time my tongue started swelling up and I was having trouble breathing so I went to an ER. About 5-7 minutes after they injected me in the thigh with an epipen, I was in mid sentence when I started having strange sensations and tremors all over my body. The injection spot, which is incredibly sore and feels like they hit my femur) suddenly became very warm and I could feel it spreading out quickly. I could hear people but I couldn't speak, everything clamped up, I couldn't breathe and I felt very confused and forgot what I was about to say to the nurse. The doctor caught the tail end of it and claimed I was having a panic attack! I heard both the nurses say that they thought it was a seizure. This happened to me once more a few yrs ago with an allergic reaction, but it was from the nurse pushing in the benadryl too quickly, which made my hands curl up like T-Rex and my eyes rolled back into my head. Is there such a thing as being allergic to epinephrine or has anyone ever experienced a seizure/stroke like reaction after being administered Epipen or Benadryl ?
  • Is there allergy medicines that you should not take with vwd
    I am wondering what can be taken for allergies or medication I should avoid for people with von willebrands?
  • Phentermine topamax and depo provera
    I'm am wondering if th phentermine, the topamax (25 mg x2 a day ) will interfer will the depo provera?

  • Swelling and pain in one of my breasts after using fexofanadine
    I took them for one week or two as an anti allergic drug and I found these conditions in my body. Then I stopped it for 6 months as I was away from allergenic country (Australia) and there was no symptoms. When I came back to Australia and needed Fexofenadine again, I used it for 1 week and I again notice swelling and pain in one of my breasts.
  • Wheezing stopped after topamax sessesion
    Wheezing noted by primary physician in this non-smoker. Stopped Topamax per doctor's instruction. 48 hours later was examined by physician and noted that wheezing stopped.
  • Happened to me- allergic reaction to rogaine
    Within the first week of usage, I began to have leg cramps, facial swelling, tightness of breath, chest pain, anxiety, and chronic headaches. Even with allergy medicines and aspirin, nothing seemed to help. At first, I felt it was though it was just simple allergies until I woke up one morning with my face so swollen that I could see my skin around my eyes without looking in a mirror. My throat began to swell to the point it was difficult to swallow. I immediately went to the ER to receive a shot and sleep all day with Benadryl. The following day, I have redness in the skin and hoarseness. The doctor told me too never touch Rogaine again or I would end up in the hospital (or worse).
  • Temazepam & fenfexodine
    Is anyone else finding the Temazepam is not working when taken with fenofexedine? I survive on a few hours of sleep a day.
  • Cephalexin 500 mg caused allergic reaction (1 response)
    I developed a rash that quickly turned to painful, itchy blistering after taking cephalexin 500mg capsules for only 2 days (the prescription was for 10 days). The rash was on my hands, legs, back, & arms. I was sent by my doctor to the hospital emergency room. diagnosed as an allergic reaction to cephalexin. treated with steroids & another antibiotic. this was one of the scariest episodes of my life. I hope people are reporting this type of problem.

  • Around the time I started itching I began allegra and was also given generic lipitor. The itching is intense, Can not sleep.Doctor upped dosage of prozac to 40 mil twice a day. I also take 1 mil klonopin 3 times a day but does not help. Doctors say it could be stress but I have had anxiety most of my life and it has never reacted like this. Any suggestions? Thank you

  • From this study (2 months ago):

  • I had 2 anaphylactic responses within three weeks of each other and I am looking for a common element. I had taken it before but prn. Then I had rotator cuff surgery and took it while away and reacted within an hr and didn't take one again until yesterday and within an hour I was back in emergency. The only common food factor other then this drug was chicken. I am pursuing, diligently to figure this out.
