They are now used worldwide, and this class of medication has revolutionized the treatment of these diseases and the quality of life for patients but it also poses risk of developing various side effects including infections, exacerbation of some neurological manifestations, cutaneous lesions or induces antibody production. Renal complications are uncommon and poorly recognized.
