hypoglycemia
"I was prescribed Proglycem at age 15 months and I am now 18 yrs 6 months. I have recently been told that it is likely that I must use diazoxide tablets because Proglycem is very expensive. I have tried to do so but I get bad symptoms like headaches, nausea etc. I do not know how my condition will be controlled if I am unable to continue with Proglycem. Prof. at Great Ormond Street Children's Hospital, London,  initially prescribed the drug and I am sure, for me, it as been a life saver.
Health professional in the UK cannot tell me why Proglycem works for me and the much cheaper diazoxide causes side effects. The use of all forms of diazoxide seems to cause excessive facial and body hair growth."
