HI Thank for asking to HCM I really understand your worry for your husband, Mam this is multiple pathology and I personally handle such cases if ever have it, for SLE the steroid is the only emergency medicine and that seldom needed otherwise there is no cure for this disease neither it causes any mortality, unless induces severe laryngeal edema, but that can be treated successfully, for other problem I would ask for hospitalization because on out door level it can not be treated for a couple of week your husband needs to be hospitalize have nice day.
