Has anyone experienced side effects from prolastin? If so, do they seem to get better the longer you take the prolastin? I was recently diagnosed as having alpha-1 deficiency. So 3 weeks ago I began receiving the weekly prolastin IV treatments.I have itching, muscle cramps and muscle aches throughout my body. So far the a Chinese lasts for a day or 2 after the treatment. Just still trying to figure out my new "normal."
