Air polymer-type A is infused into the uterus to allow for visual assessment of fallopian tubes during an ultrasound examination called a sonohysterosalpingography.[2]

The most common adverse reactions are pelvic pain and abdominal pain, nausea and faintness (caused by a nerve and blood vessel reaction called vasovagal reaction) and post-procedure spotting.[2]

History

edit

The US Food and Drug Administration (FDA) approved air polymer-type A based on literature reports.[2] To evaluate how well air polymer-type A works, the FDA primarily used data from two trials.[2] Trial A[4] was conducted at a site in Italy and Trial B[5] at three sites in Poland.[2]

Evaluation of side effects was based on multiple literature reports and collected safety reports from countries where air polymer-type A is already approved.[2]
