Kidney disease patients frequently ask healthcare providers: “Can I take this medication long-term?”
The answer depends on the medication’s safety profile. Some drugs with high safety margins can be taken indefinitely, while others with higher risk profiles should not. Additionally, certain medications aren’t just safe for long-term use—they’re essential for long-term management.
Let’s break down the categories:
Medications Safe for Long-term Use
These medications have low adverse reaction risks and provide significant benefits, making long-term use necessary. This category primarily includes medications for managing hypertension, diabetes, and high cholesterol—conditions very common among kidney disease patients.
1. Blood Pressure Medications
ACE inhibitors (ending in -pril, like lisinopril, enalapril), ARBs (ending in -sartan, like losartan, valsartan), calcium channel blockers (ending in -dipine, like amlodipine, plus non-dihydropyridines like verapamil and diltiazem), beta-blockers (ending in -lol, like metoprolol), and diuretics (like hydrochlorothiazide) are all first-line antihypertensive medications.
Hypertension causes severe damage to kidneys and cardiovascular system, while first-line blood pressure medications have relatively low serious adverse reaction risks. Patients with high blood pressure can safely take these medications long-term.
2. Diabetes Medications
Metformin, SGLT2 inhibitors (ending in -gliflozin, like empagliflozin), and GLP-1 receptor agonists (like semaglutide, liraglutide) are first-line diabetes medications. High blood sugar causes significant damage, and these medications have manageable side effects, making them suitable for long-term use.
3. Cholesterol-lowering Medications
Statins (ending in -statin, like atorvastatin, simvastatin) lower harmful LDL cholesterol, have some effect on triglycerides, prevent atherosclerotic plaque formation, and prevent cardiovascular events. For patients with high cholesterol or cardiovascular disease history, long-term use is necessary.
(Note: Fibrates like fenofibrate, while useful for very high triglycerides, don’t provide cardiovascular protection and are generally not used long-term.)
Medications Requiring Caution for Long-term Use
These medications have moderate to high adverse reaction risks. It’s best to stop them when possible, but if discontinuation isn’t feasible, they may need to be taken long-term despite the risks.
1. Corticosteroids and Immunosuppressants
Corticosteroids (like prednisone, methylprednisolone) and immunosuppressants (like tacrolimus, cyclosporine, mycophenolate mofetil) are used to treat nephrotic syndrome, typically for six months to a year and a half. If the condition relapses, treatment duration extends.
For lupus nephritis, which has an aggressive course and high recurrence rate, lifelong low-dose corticosteroids may be necessary to prevent relapses.
2. Uric Acid-lowering Medications
Patients with hyperuricemia or gout can take allopurinol, febuxostat, or probenecid to lower uric acid levels. If uric acid levels stabilize around 300 μmol/L (5 mg/dL), discontinuation can be attempted. However, if levels rebound, medication should be continued.
3. Pain and Fever Medications
NSAIDs and analgesics relieve cold symptoms and pain, including ibuprofen, acetaminophen, naproxen, and indomethacin.
These medications have some kidney toxicity. Short-term use (preferably not exceeding 3 days) is generally safe. Some patients may need them chronically for pain management, which carries kidney damage risks.
4. Stomach Protection Medications
Proton pump inhibitors (PPIs like omeprazole, lansoprazole) increase kidney damage risk with long-term use. Don’t exceed recommended treatment duration.
Medications NOT Recommended for Long-term Use
These medications have moderate to high adverse reaction risks, and alternative medications are available, making long-term use inadvisable.
1. For Patients Planning Pregnancy
Tripterygium wilfordii (thunder god vine) and cyclophosphamide should not be used long-term due to gonadal toxicity, which can cause infertility. After reaching a certain cumulative dose, switch to other immunosuppressants.
2. Potentially Kidney-damaging Medications
Some medications that may cause kidney damage include aminoglycoside antibiotics (like gentamicin, streptomycin, neomycin) and aristolochic acid-containing herbs. These can often be replaced with alternative medications, so minimize use or shorten treatment duration.
Important Considerations
Whether a medication can be used long-term also depends on the condition being treated.
For example, diuretic antihypertensive medications should be used long-term for primary hypertension to control blood pressure. However, when used for diuresis and edema reduction, they should be discontinued promptly once edema and proteinuria improve. This requires flexible clinical judgment from healthcare providers.
Key Takeaways
- Work closely with your healthcare team to regularly review all medications
- Never stop prescribed medications without consulting your doctor
- Be aware of potential side effects and report any concerns
- Some medications are essential for protecting your kidneys and overall health, even if taken long-term
- Alternative treatments may be available for medications with higher risk profiles
Always consult with your healthcare provider before making any changes to your medication regimen. This information is for educational purposes and should not replace professional medical advice.
