Hi, new to this group. I've had OLP since early 2018. I was diagnosed by an oral tissue specialist at the Anschutz campus, CU school of medicine. He put me on hydroxychloroquine (HCQ) for a maintenance drug and it has helped immensely. I've not had to use clobetasol, nystatin or dexamethasone for 2-3 yrs. I will occasionally use tacrolimus on red spots. Currently on 200 mg pill, 2 times daily. I have to be very careful about sun exposure, as my lips can develop sores very quickly, and heat alone can cause flare ups on my lips So, I use Elta MD UV lip balm, spf 36....it is zinc based (becomes transparent as it's absorbed, so you only have white lips for a while), and a WIDE brim hat. In the winter I use a buff up over my lips, as cold and wind can affect my lips. One must get quarterly blood work while on HCQ, as it can affect kidneys, blood work must look at eGFR and creatinine.
