Maybe never: Your question implies that things could do better in your case, and in absence of details, will answer generically. Rebif is an interferon, and is a member of a group of older meds that have been substantially made inferior by the newer agents coming onto the market, as drugs such as tysabri, (natalizumab) gilenya, tecfidera, are far more effective regarding relapses, disability, eventual outcomes.

How quick it works: The answer depends on what you mean by "work". The medicine starts to work as soon as you take the first injection. It works by preventing future MS attacks, by interfering with the function of white blood cells that promote MS. The medicine wears off, so repeat injections may be needed.
