• ‘It was awful for me’: one MS patient shares her experience with Tyruko

Scores of people with multiple sclerosis (MS) have suffered debilitating side-effects after being put on to a cheaper new drug as part of an NHS drive to save money.

About 170 MS patients at Charing Cross hospital in London have had complications, including a relapse of their illness, after being switched from Tysabri to a different drug called Tyruko, made by the pharmaceutical company Sandoz.
