Chemical sensitivity is a common symptom in Dysautonomia. I have a couple of true allergies to medication, but I also experience overdose symptoms at normal medicinal dosages. I'm not sure if this is what you are referring too, but I'd recommend starting all new medication with the smallest dosage possible.
omg yes. i have pots and nmh
and i have had an reaction to every med they have put me on. idk what is next. anyone else have this problem too???
What type of reactions are you having and how severe? Are you also having food allergies?
Oh yes, We are all leary about anything that goes into me. I have had Xylocaine for years and now react to it. My neurologist, an autonomic specialist also says that they may not be true allergies but a cholenergic response from the nervous system. I have to be premedicated with IV steroids and IV Benadryl before most meds. I have a Hickman Catheter and was an Oncology nurse so this helps but it is scary when you don't know what is next.
My reactions started out as rashes, hives, itching but now it is a Bronchospasm. I have to have the steroid and Benadry to stop it
Some POTS patients have been diagnosed mastocytosis. I don't know a lot about it personally, but if you're starting to have increasing responses to medications/foods/etc, it might be worth reading up on to see if this might be a fit for your symptoms. I can try to get you in touch with the people I know who know a lot more about it if you want . . . just let me know.
