There is no consensus regarding treatment of interstitial pneumonitis induced by (peg)interferon and ribavirin. Upon review of the literature, three options are possible: first, to stop combination treatment of HCV and wait until the disease resolves, which was done in a limited number of cases [7] [8] [9] [10] ; second, to give steroids, although dosage and route of administration regimes vary widely [6, 10-18, this study]; and thirdly, in therapy-resistant or relapsing cases, adding azathioprine to steroids may be beneficial in order to resolve the interstitial pneumonitis [11] .
