My son starting passing out when he was 12 he is 16 in August. He passes out 2/3 times a day 4/5 a week. He passed out in the road once at 15yrs old, his friends had to drag him out of the road unconscious either that or he would of been killed. Life is terrible for him since then he doesn't leave the house in fear of passing out. We have been passed from pillar to post but last September 2014, after having 2 inconclusive tilt gets & also having a loop recorder implanted in his chest he has now been diagnosed with low blood pressure. In February 2015 he was prescribed fludrocortiosone even though it has made a difference its not significant enough, so next week he is being put on Midodrine. I know this is a short lived drug so how often do you need to take it during the day? Will this medication stop the passing out for good or just help improve the situation. He desperately wants to start college this September but he has been told due to his condition he may not be able to. This is heartbreaking as he is full of ambition.
