A scheme designed to give patients access to promising medicines which have not yet been licensed. This means they have not been fully tested to see if they are safe, if they are effective or what side-effects they may cause. It is only for drugs that may provide a benefit to people with a life -threatening or seriously disabling condition, where there is no other treatment available to them. The scheme also allows doctors to prescribe a drug off-label. This means it can be given for a condition, an age or a dose that is it not licensed for. This scheme began in March 2015.
