This is a descriptive case report of a 30-year-old man with massive epistaxis, echymosis on arms, abnormal CBC and increased plasma urea and creatinine level (i.e. above normal range). Probably, these are as side effects of interferon beta-1a injection. This is the first report according to our literature search (Pub Med, Google scholar, ISI web of knowledge, ProQuest, MD consult, Science Direct, and SCOPUS) about interferon beta-1a related abnormal kidney function tests hereafter. Abnormal kidney function tests (i.e. increased plasma urea and creatinie level) is not a known as side effect of interferon beta-1a. This case indicates, likely potential for development of these side effects with this medication.
