Also, if you are taking 2 gm desferal subcutaneously, use 20 ml water (5 ml per 500 mg), or more water if you intend to dilute it so it lasts more than 12 hours. You may not find this in the prescribing information, but the doctors at the conference stated that it is actually more effective to spread the same dosage out over a longer period of time. This method has long been used by Shilpa to make her desferal last longer. When I heard the doctors recommend this at Singapore, I wrote this in my notes. Shilpa is a genius! It has worked well for her.
