Causes, Cures, And Remission.I have had dermatographia for just a few months. I found my way to this site mostly out of fear; that eventually my zyrtec would stop working and that my dermatographia would not go into "remission" so to speak. I believe my DG to have been brought on by an allergy to Ranitidine, and as such I do not have cause to believe it would "go away with time" either. I have 2 other rare conditions as well, which I am glad to discuss if anyone would like.
These other conditions are a form of "reflux" referred to as LPR, and Celiac's disease. I'm so glad to have found this site so that I don't have to feel like I'm the only one. (with DG, but also with these others).
Apparently, people with an autoimmune condition (such as Celiac's) are prone to have a higher "ANA titer" according to a friend who is a nurse and has DG herself; and these conditions are prone to cause dermatographia.
My purpose for sharing "my story" in this way is to provide a common central place for us to share things that have worked:
1) What do you believe to have caused your DG? At what point did it develop? Were there any new catalysts in your life at that time? (Allergens, stress, medications)
2) How do you treat your dermatographia?
3) What stories have you heard of people's DG going away?
To answer my own questions posed, and start the conversation rolling... ;-)
1) I believe I had a second, more drastic response to the drug ranitidine. The first time I took the drug gave me discolored stool, so I thought I could deal with the same side effect a second time. (Whoops! They say hindsight is 20-20...)
2) I use zyrtec about every other day; I try to minimize its use so that I don't build a tolerance to the drug.
3) I do not know of anyone who has had DG and that it later went away for... I only know that the medical community does not agree on a cause, and that my allergist says it can go away in months or in years but there's no way to tell when (or if.) :-p
