My brother is in cardiac failure requiring diuretics, beta blockers, anticoagulants daily but is reacting to every single medication, both tablets & IV or syrup form. His IGE was tested and was 560! How can he lower his levels? Medication is necessary specially diuretic (needs at least 4litre of fluid expelled daily) but is in a lot of pain due to his immune reaction to the meds...what would you suggest please?
