For the past two months, I've been using Haegarda 3000unit Inj to manage my Hereditary Angioedema (HAE). This medication has been a game-changer in preventing swelling attacks. However, I've experienced some side effects that I haven't heard discussed much. I'm curious if anyone else has gone through similar issues. The drug information mentions some serious side effects, and while I haven't had any of those, I am concerned about the long-term implications, such as potential blood clots or allergic reactions. It's strange, but I think the injection site irritation is actually getting worse, not better. I feel that it's important to share my experience, so anyone considering this medication can better understand what to expect.

I had no idea Haegarda could cause such severe side effects. Is it really worth the risk? Anyone have any thoughts on that?

Wow, I can't believe you're having such a hard time. I had a friend who used this and didn't have any issues. I hope someone with more experience chimes in.

I've been on Haegarda for a few years now, and I can say that the injection site irritation usually goes away after a couple of weeks. If it's getting worse for you, it might be worth talking to your doctor about it.

I'm so glad you brought this up. Dizziness and nose or throat irritation can be really challenging to manage. I've had to switch to using a humidifier because the nose/throat irritation is so bad. I haven't had any serious side effects, but I take it seriously when I have to miss a shot. Have you tried anything for the irritation?
