I have been on cetirizine for several years for itchy hands and feet, the dermatographism seemed to be connected to the intake of cetirizine and lessened in severity when I changed my allergy
pill or stopped all together. I was given rounds of Prednisone, shots,
Triamcinolone Acetonide 1% cream which causes periorbital dermatitis. That lead to having to take four weeks of minocycline. I now will have spontaneous eruptions of a red itchy rash with small raised bumps mostly on my torso or arms.
