Hi everyone, Although this is my first post I have been visiting this this over thw last 2 years since i was diagnosed… So I started on rebif with the rebismart a little over 2 weeks ago, and have just done my 2nd 22mg dose. So far through this titration period no side effects I hope it stays this way!! What I am actually trying to find out is how long the first titration cartridge is supposed to last, I have done the 2 weeks of 8.8mg and now 2 doses of 22mg and according to my device it will let me do another dose out of the first cartridge does this sound right. I didnt think it would last this long??? Thank you Xx
Unfortunatley I cant answer your question as I’m SP and on no DMD’s but thought I’d reply just to bump you up the board in a hope that someone will give you the answer your looking for. Oh and welcome by the way Sue x
I went straight on to 22mg and at the time used a different auto injector with pre-filled single use syringes but with a little maths I think I can answer your question.
I now use the Rebismart and do 3 x 44mg injections per week out of a single cartridge.
This means that a cartridge contains 3 x 44 = 132mg.
You have already completed 2 weeks of 3 injections at 8.8mg each and 2 doses of 22mg so:-
6 x 8.8 = 52.8
2 x 22 = 44
Subtotal = 96.8
132 - 96.8 = 35.2mg (this is what is now left in your cartridge)
Answer = yes, your cartridge will let you complete another injection out of the initial cartridge.
Hope this helps. It’s great that you haven’t had any side effects, I doubt you will get any now as your body should be getting used to Rebif. It sounds as if you are coping really well.
Glad to hear that you started rebif two weeks ago and is going well (and hope it continues to do so). I made a decision this Wednesday to start my 11 year old son on Rebif aswell and it was a positive to read your column I hope my son does’nt get any side affects aswell.
Good luck and well done.
Thank you for your kind comments, Spursfan - I hope your son gets along with rebif ok, good luck Xx
