Being seriously needle-phobic myself, I was very surprised to find that I was able to self-inject first Byetta, and then more recently Victoza, without any problems.
This could be due to the fact that the needle is so tiny that there's no pain at all when injecting into my tummy.
The only side effect I suffered on Byetta was sometimes a feeling of nausea. This went away when I switched to Victoza.
The plus side it that it's almost completely killed my appetite, with the result that I am eating far less, and am slowly and steadily losing weight, which can't be bad.
So please do give it a try - if I can do it (bear in mind I still can't do finger-pricking because of my phobia) then you may find it OK!
I am having one occasional symptom, which may or may not be the result of using the Byetta, which is very occasionally (about once every 2-3 weeks) feeling sick and throwing up. After I do I feel OK again. Anyone else on Victoza get this?
