Here is My Question:
Do you have to wash out Betaseron before switching to Ocrevus?
There is no scientific or medical reason to, "wash-out" any interferon beta therapeutic agent (this includes Betaseron, Extavia, Avonex, Rebif or Plegridy) before starting another disease modifying therapy (DMT), unless the interferon is being discontinued because of a lab abnormality or side effect. If the switch is occurring for either of these reasons, it is prudent to wait until the lab abnormality or side effect improves before initiating the new DMT. The necessity of waiting to start a new DMT is usually based on the clinical circumstances and judgement of the treating physician.
