I have only been on Repatha for 14 weeks now but I immediately noticed from the day after the 1st injection a runny nose. I have to wipe my nose about 20+ times a day, higher than that the first couple days after the injection. I had a lipid panel done immediately after the 3rd injection, 6 weeks, and my LDL dropped from 122 to 31 so it does work. Coincidentally I think, I am on my 2nd occurrence of a bad cold called a rhinovirus (not a mistype, there really is such a diagnosis). I also have a rare blood cancer which causes my immune system to not function properly so that may be the reason for 2 severe colds in about 12 weeks
Hope this helps hope this helps
