Hi Diab,
Your ferritin is low enough where you should be able to control it with Exjade alone...if you can tolerate it. You might want to try splitting the dose and trying it with different soft foods, to see if you can tolerate the taste. I have hear many reports from people whose ferritin level was stuck and wouldn't go down, but once they split the dose, it finally continued down to under 1000. If you have decided to take desferal, you can use it by itself or add L1 also. At your ferritin level, your approach can be very flexible, as long as you make sure you are regularly chelating. Keep in mind that desferal only works while you're using it, unlike the oral chelators which do chelate for some hours after ingesting.
