If anything call their nurse line. They are very well informed. I was on Techfidera for a while, and they knew answers to almost everything, but in the case they don't, they have someone call you back either the same day or the next day.

Either of these answers would work. If you doctor has prescribed the change, he or she is the one to ask first.

you definitely need to check with your Dr. everyone is different. When I switched from techfedra to tysabra the office took me off of techfedra the office visit before my infusion of tysabi.

Ask your doctor or pharmacists check first please
