I have been using Victoza for 4 weeks - .6m first week, 1.2 second week and 1.8 last 2 weeks. The last 10 days using 1.8m dose has produced a red itchy rash around the injection site. It was OK for the first 4 days at 1.8m but then I started reacting. I have cut back to 1.2m again, but am wondering if there is something I have done or can do to improve the outcome of the dose at 1.8m. It has improved my blood glucose and curbed my appetite - and the other side effects have subsided nicely. Thanx for your information.
