Hello Everyone,

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!

Thank you

    I have lichen planopilaris which was caused by a flu vaccination and, like you, I dont know which strain in this vaccination caused it and dont know what to do about it

      Literally within 24 hours. I went out like a light for three weeks with something flu like and then my scalp was burning and itchy and the hair loss started.

    Poor baby!!! It is funny (as in weird, not haha) that you were told that you have PR, when it was actually LP. I have had LP for over 20 years. Suddenly, I had rash all over, not like the recurring mess of LP. Diagnosed with PR. I researched, and found a cream that really did work. I noticed that the same people make one for LP. It is all natural, so I definitely thought it was worth a try. You can find it online. It is called Lichenseze. The ingredients are listed. It is the first thing I have found that actually works!
