Reformer : “Following some very difficult months it is amazing to have this silver lining. “Thanks to this UK-wide collaboration, we now know that Dexamethasone works for the very sickest patients with Covid-19.“This is the first treatment that is proven to save lives from Covid-19 and can now be used to treat NHS patients.“It is great that this treatment is one that is already available and affordable so it can be used immediately.”Dexamethasone, a common steroid that costs about £5 for an entire course of treatment, has been shown to cut the risk of death by a third for Covid-19 patients on ventilators.It was also found to cut deaths by one-fifth for patients who require oxygen but do not require ventilation.Raymond Hamill, senior.
