The 37-year-old was treated with methylprednisolone - the main drug then available - but had repeated relapses.
It wasn't until a neurologist suggested she trial Tysabri that her life changed. For the past 18 months she had taken an infusion of it six-weekly. "I'm a changed woman."
From tomorrow, Pharmac will also help hospitals fight "superbugs" (multi-resistant bacterial infections) with the funding of a new antibiotic, ceftaroline fosamil.NZME.
