For Stage 4 Chronic Kidney Disease, medications are highly personalized to slow kidney decline and manage complications. Your hemoglobin (11.5) is currently in a safe target range, so anemia treatments are likely not needed yet. Typical medications prescribed include: 1. Blood pressure controllers (like ACE inhibitors or ARBs) to protect kidney function, 2. Statins for cardiovascular protection, 3. Sodium bicarbonate or phosphate binders if blood tests show electrolyte imbalances, and 4. SGLT2 inhibitors to slow disease progression. You must strictly avoid NSAID painkillers like ibuprofen. Please consult your nephrologist to tailor these medications safely based on your specific blood pressure, potassium levels, and urine protein.
