It is safe to give. You may use ARTHRO-IONX along with other medications or supplements. It is homeopathic in nature and so it will not negatively interact with other physical substances. Homeopathic ingredients are diluted and succussed so many times the product would have negligible amounts of Phosphorus. Initially I would give 10 drops with breakfast and 10 drops with supper. After improvement then you can give it once a day. OMEGA 3,6,9 is also helpful for arthritis.
With renal failure I recommend PROBIOTICS which will improve digestion and decrease the amount of waste that the kidneys will need to dispose of. Later you might also want to try DIA-IONX because it contains homeopathic remedies that help to support the kidneys since diabetics need help in that area.
Please let us know how you do.
