Good evening. The treatment for DLE is a bit tough as not many medications work for it. PLaquenil is the drug of choice but since you are unable to take it, low dose of steroids should help. If you only have butterfly rash and no rashes elsewhere, you can take a course of oral steroids along with topical creams like tacrolismus( after presciption from your rheumatologist). I wont recommend topical steroids for the face as it can cause skin atrophy on that site. Also the dose of MTX is quite low. It starts being effective from 15 mg. It can help in the skin problems due to SLE. Avoid going in the sun and if you have to use a good sunscreen with Protective FActor of at least 50. Only having rash is not too serious, so you dont need very strong medications for it. Hope the information was useful.
