Pratik,
Carao may not have a significant impact on how often a thal major is tranfused. This being said, I definitely notice a sense of well being, more energy between transfusions and an improvement in color when little A takes carao.
I think that carao may be effective in keeping the transfused red blood cells healthierand perhaps making them last a little bit longer. It will also protect organs from the harmful affects of free iron. I think it is definitely worth a try. The smell of the drink is absolutely terrible, but the effects are worth enduring the taste and smell.
Best,
Sharmin
