I also got acne from lithium. Never had skin problems before lithium. I used it as mono therapy for a long time so there were no other drugs present. Hard to get rid of and scarring. Now that I am off lithium and have been for a long time, I am still dealing with this. A little less severe but I see a dermatologist for treatment. The treatment I got has cleared it right up and is diminshing the scarring. And it is one treatment I can live with but many acne treatments are harsh and a bit unbearable.

Just one article for you...your not crazy..maybe find some more articles and show them to your dr.
