Placebo Penthrox inhaler clinical trials

Methoxyflurane for IUD Insertion and Endometrial Biopsy

This study is looking at whether a pain-relieving inhaler called Penthrox (containing Methoxyflurane) can reduce discomfort during procedures like fitting an IUD or taking a womb lining sample (endometrial biopsy). We want to see if it makes these common procedures more comfortable for you.
