Mariam,
Dear i can totally understand your fears,but please try to understand that if you'll get panicked,who'll help aysam?
You said you have an appointment in nov,till then you can stop exjade? and then ask that new doctor if you can try it again? and mean while watch if his levels get to normal,Desferal IV is the best option for lowering ferritin.I believe L1 is also available in Austrailia,but i don't know about the age limit,but keep in mind that L1 also have some side effects,but my daughter is doing well with L1 Alhumdulillah.
I hope aysam will be fine soon,please keep in touch with smurfette as she is very knowledgeable and she knows about the conditions and facilities available in your country.
Zaini.
