Etymologically, the entry records: From rib(oside) + -a- + -vir- (“antiviral”) + -in. Root origin matters for spelling because borrowed morphemes (Greek, Latin, Old French, Old English) carry their source-language orthographic conventions into modern English, which is why historical etymology is often the cleanest predictor of whether a cluster like "-ough", "-eau", or "-tion" will appear. For readers arriving here from a spelling check, the authoritative guidance is: the correct English form is ribavirin, spelled R-I-B-A-V-I-R-I-N, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
