Extavia side effect question

I am currently using extavia and have been for at least 18 months. I had very mild flu like symptons in the first week of usig the drug but nothing since. However I have recently had two bad reactions (bad flu like symptons) following injections and I was wondering if anyone else had experienced this.

I’m sorry I know nothing at all about this drug so am bumping you up so someone can help.
