People in the early stages of Chronic Kidney Disease can take medicines to keep the disease from getting worse. For example, many people with Chronic Kidney Disease should take medicines known as “ACE inhibitors” or “angiotensin receptor blockers.” If your doctor or nurse prescribes these medicines, it is very important that you take them every day as directed. If they cause side effects or cost too much, speak to your doctor or nurse about it. He or she might have solutions to offer.
