Make life long anticoagulant therapy free on prescription

I was diagnosed with a condition called factor v leiden mutation when I was 19. I have to take life long medication to prevent a fatal blood clot. I already have had 3 clots. One of which was multiple and on my lungs. I spent 48 hours in icu and a further 10 days on a hospital ward. After my diagnosis the rest of my family where tested as it is a genetic disorder. factor v leiden is just one condition that anti coagulation therapy is used for. I am 50 times more likely to clot than someone who dosent have this condition.
