At the age of 17 (now 31) I was diagnosed with Familial Hypercholesterolemia and had genetic testing to prove this. Cholesterol levels were 11.7 mmol. Started simvastatin at 20mg, cholesterol did not lower. Increased to 40mg and slight alteration but severe muscle pains. So bad i couldnt get out of bed at one point. Was then started on atorvastin and same effect on lower dose. Tried ezetimibe 10mg with rosuvastatin 5mg and levels down to 5.8mmol. Consultant in lipid clinic now wants me to try adding fenofibrate 134mg a day. Started off taking 67mg a day and witihin a week i am crippled again and now having palpitations. Stopped medication for now.
