Qiji,
As Umair has said, Exjade is used daily (as per the documentation that Umair has provided). It should be taken under the supervision of your doctor and your doctor should also control your dosage. Exjade is usually started at a dose of 20mg per kilogram of the patient's body weight, if this is well tolerated then the dose is increased to 30mg per kilogram of the patient's body weight. My understanding is that exjade is effective at 30mg/kg 7 days a week, therefore I don't know if it is good enough to take it only a few days a week.
Also, any patient on exjade MUST have a blood test (cbc, metabolic panel, ferritin) and urine test done every 3 weeks. If you are going to use exjade and desferal in combination - this MUST be prescribed by your doctor and the patient MUST be followed very carefully.
My 10 year old is on combination exjade daily/desferal 5X week - therapy and he is being watched very carefully. So far things seem to be going well, and his ferritin seems to be dropping (we will know for sure at his 6 month follow up). But I must stress that a research team in Oakland and our doctor here watch him like a hawk because he is on this treatment as part of a trial. The researchers in Oakland are constantly keeping in touch with me via phone calls and emails, the doctor in Oakland has called me at home to make sure that we are doing well.
I hope that this information helps, best of luck with your treatment,
Sharmin
