Hi all, I'm not having much luck in my googling to help me process & understand what went down during my 1st infusion this Monday! When I got to just under 1/2 of my first dose (so, less than 1/4 of what I would be getting on an ongoing six monthly basis), my blood pressure dropped then I felt woozy/faint... was popped in a lying down position and my body started to shake quite violently. Teeth chattering etc. Felt quite out of it and trippy for quite a while. I wouldn't say I felt fevery as such but was maybe hot, cold and sweaty at the same time. My best friend witnessed this all and said my heart rate increased and I looked a little flushed in the face during this reaction. I do sometimes get panic attacks, though hadn't had one for a while. My current dilemma is not knowing if this extreme reaction was a panic attack or whether it was an infusion reaction directly related to the meds. The nurse said it was "rigors" and something she has seen before with other meds. I am really unsure of how to proceed with the medicine and am wondering if anyone has experienced similar. Thanks.
