Can I go back to Saxenda if I get a rash after the last dose?

Good morning
Most likely, I got rashes after using saxenda, itchy patches that only go away after treatment with encorton. I'd like to add that this is my 3rd attempt at saxenda and it's the first time something like this has occurred. My question is, if I finish the encorton treatment (in about a week) and the rash goes down, can I try another approach? Is there a very high probability that the rash will come out again? Thanks in advance for your reply
