I've been suffering with this condition for over 2 months now. It first started off as itchy dry scaly spots but now it has covered my whole stomach, upper arms going down to my forearms now, and vaginal area. I was first diagnosed with pityriasis rosea but a biopsy confirmed it as lichenoid dermatitis and possibly caused by drug eruption due to eosinophils found. Also through my own research parakeratotic foci are more common in drug eruptions, which were also found in my biopsy.
However, I'm not sure what medication could have caused this. I was on pantoprozole (proton inhibitor) for a couple of weeks in December but I had stopped taking it and the first signs of rash started appearing in March. Can the reaction be this delayed even after stopping medication? Also I have been on levothyroxine for the past 3 years.
Has anyone experienced lichen planus due to a drug eruption? What were your symptoms? I am so desperate for any answers!
