"went into anaphylaxis after third dose. increased anxiety. had to go to the emergency room via ambulance. mouth, tongue, &amp; throat were swollen, chest was tight, severe all over itching, &amp; itching throat. found out this only works 50% of the time. that it&#039;s a hail mary drug. it works on half of the people, makes the other half worse. be very cautious with this one. because it&#039;s a 50/50 chance."
