This topic is way too complicated for here and probably whatever Dr you see.
That drug involves prostaglandins.
You may have genetic quirks related to that drug. Ignore people who come on here that says thousands used it with no problem. You appear to have a problem for whatever reason . Possibly genetic.
I had a bad reaction to a MRI contrast. I have no doubt that prostaglandins were part of it.
Prostaglandins are involved with the infamous niacin flush. I tried an experiment. Indomethacin knocked out the flush. You could try asking for indomethacin but it’s not a drug to take long term
You are going to have to do the research on this because you can’t rely on Drs to figure it out .
I have major genetic factors related to drugs and always look them up.
Check this site and look for anything you might have been taking at same time

By the way, try asking Twitters Grok program and see it can direct you to issues to investigate including genetics.
Thank you for all that information. Have you had a DNA test via ancestry or some other service to determine these issues? My children have gotten these tests and I was considering it. What are the best ways to figure out if you have genetic predispositions to such things?
