My 16 year old daughter was diagnosed with POTS about a year ago when we saw Professor Matthias who put her on midodrine, which has helped enormously as she now gets a warning before fainting(usually). We have been put into the care of our local health authority who are unwilling to prescribe midodrine. Does anyone know of a consultant that would be willing to help us get some more midodrine? She will run out of the drug in a couple of weeks and we don't want her collapsing and hurting herself again. She faints at least once a day, it was three times yesterday, and we are desperate.
