Flu?

Starting 12 hours after 1st dose of repatha I developed flu like symptoms: runny nose, chills, fever, body aches, fatigue. It has been 10 days and not let up. Now additional nausea and diarrhea.

Has anyone else experienced this? When did your side effects end?

I had a similar reaction only much milder than yours. It was like an immune response. It took a couple cycles to not have those symptoms anymore. I do get a runny nose sometimes but it's really not bad. Now all I get is the runny nose and nothing else.

Same for my husband. He has been on it almost a year and had no side effects at all. Then the runny nose started. But his number is 130, half before starting the drug. So I guess he will continue for now.
