I've been on Hizentra for a few months now to treat my CIDP, and I've been having some concerning side effects. I'm wondering if anyone else has experienced similar issues or if my symptoms are out of the norm. I've been feeling extremely tired and weak lately, and I've also noticed some bruising that I can't explain. I've read about the serious side effects, but I'm hoping it's nothing too serious. Has anyone else had these symptoms, or know what might be causing them?

I had some really bad headaches and dizziness when I first started. My doctor said it was probably just my body adjusting to the medication, and it went away after a few weeks. Keep an eye on it, but don't worry too much.

I've heard that mood changes can be a side effect. Have you noticed anything like that?

I've been on Hizentra for a while now, and I've had some side effects, but nothing too bad. I get some irritation at the injection site, but that's about it. Hopefully, it stays that way.

I've been on this stuff for years and have had zero side effects. Knock on wood...

I wish that Hizentra didn't need to be injected. Any tips for making the injection process easier? I think this would be fine if it was just a daily pill.

I'm glad I found this thread. I've been having some of the same symptoms and was starting to worry. Thanks for sharing your experiences!

I just started Hizentra last week, and I'm already feeling like I have the flu. Is this normal? I hope this goes away soon.
