Key takeaways
Certain medications and substance use can raise your risk for kidney damage.
- The highest risks depend on dose, duration, hydration, existing kidney function, and other health conditions.
- NSAIDs, certain antibiotics, lithium, contrast dye, some antivirals, and chemotherapy agents are common medication-related concerns.
- Heroin and other illicit opioids can contribute to kidney injury, including through rhabdomyolysis and overdose-related complications.
- Early kidney damage often has no symptoms, so blood and urine testing matter.
- For prescribed medicines, call your prescriber before changing anything. For substance use, ask about medical detox rather than quitting alone.
Some prescriptions, over-the-counter medicines, and illicit substances can strain or damage your kidneys. Your risk of kidney damage is higher when you take these drugs at high doses and/or for a long time, if you don’t stay hydrated, or when you already live with kidney disease.
While there are risks to taking some medications—and major risks with misusing them or using illicit drugs—you should talk to a medical professional if you’re concerned. Do not stop a prescribed medication on your own. If substance misuse or illicit drug use is part of your concern, medically supervised detox may be the safer first step.
What is kidney damage?
Kidney damage means the kidneys are not filtering blood, balancing fluid, and removing waste as well as they should. It can happen suddenly in the form of an acute kidney injury or develop slowly as chronic kidney disease. Diabetes and high blood pressure are the leading causes of kidney disease.1 Certain medications, toxins, dehydration, and substance use can also raise your risk of kidney damage.
Drug-induced nephrotoxicity is a kidney injury caused by a medication, toxin, or substance. Substance-related injury may come from the drug itself or from complications surrounding its use, including overdose, dehydration, infection, sharply elevated blood pressure, or muscle breakdown.2,3
The next steps depend on whether you’re concerned about a prescription or a substance you misuse. If you take a prescribed medicine, talk with the doctor who prescribed it before stopping or changing the dose. If ongoing drug or alcohol use may be part of the problem, getting medical support can reduce withdrawal risks and reduce the effects of drugs on your body.
How drugs and substances damage the kidneys
Drugs and substances can damage the kidneys by reducing blood flow, directly injuring kidney cells, forming crystals or blockages, disrupting fluid and electrolyte balance, or triggering rhabdomyolysis.
- Reduced blood flow: NSAIDs can change kidney circulation, while cocaine and methamphetamine can cause intense vasoconstriction or severe blood pressure changes.4,5,6
- Direct cell injury and inflammation: Some antibiotics, antivirals, lithium, cocaine, and contaminants associated with illicit drug use may injure tubules or other kidney structures.2
- Crystals or obstruction: Certain medicines can crystallize in urine or interfere with normal drainage, especially when dehydrated.2
- Rhabdomyolysis: Drug overdose is a risk of rhabdomyolysis, which is the rapid breakdown of muscle tissue. Rhabdomyolysis can lead to kidney damage.7,8
- Fluid and electrolyte disruption: Substance use may cause vomiting, diarrhea, heavy sweating, poor fluid intake, and dehydration. Mild, chronic dehydration can lead to permanent kidney damage over time; severe dehydration can quickly damage the kidneys.9
Existing kidney disease, diabetes, high blood pressure, older age, or combining multiple kidney-stressing medications and substances can make these effects more dangerous. Your doctor can use blood and urine tests to help identify any kidney issues and recommend any changes to your treatment or lifestyle.
Top 10 drugs that cause kidney damage
The top 10 drugs that cause kidney damage include common medications and illicit substances. The risk is not the same for everyone, and many of these medicines can be safely used when monitored by a clinician.
| Drug / Substance | Type | How it harms kidneys | Main risk context | What to do |
|---|---|---|---|---|
| NSAIDs | OTC / Rx | Lower kidney blood flow; may worsen AKI or CKD risk.4 | High dose, long-term use, dehydration, CKD, high blood pressure. | Use only as directed; ask a clinician if kidney risk is present. |
| Aminoglycoside antibiotics | Rx | Can injure proximal tubule cells through direct tubular toxicity.2 | Hospital use, prolonged therapy, older age, existing kidney disease. | Do not stop antibiotics alone; ask about monitoring. |
| Diuretics | Rx | Can contribute to dehydration and affect kidney filtration when fluid balance is off.2 | Poor fluid intake, vomiting/diarrhea, multiple blood pressure medicines. | Call prescriber if symptoms of dehydration or kidney issues appear. |
| PPIs | OTC / Rx | Associated with interstitial kidney inflammation in drug-induced nephrotoxicity discussions.10 | Long-term use, multiple risk factors, unexplained kidney labs. | Review continued need with a clinician. |
| Certain antivirals | Rx | Some antivirals can form crystals or injure tubule cells.2 | High doses, dehydration, existing kidney disease. | Ask about dose adjustment and kidney monitoring. |
| ACE inhibitors / ARBs | Rx | Can alter kidney filtration pressure and potassium balance.2 | Kidney artery narrowing, dehydration, diuretics, CKD. | Do not stop on your own; ask about labs and monitoring. |
| Lithium | Rx | Can contribute to chronic interstitial kidney changes and requires monitoring.2 | Long-term use, dehydration, dose changes, interacting drugs. | Work with psychiatry/medical prescriber; monitor levels and kidney labs. |
| Contrast dye | Procedure-related | Can contribute to kidney injury in susceptible people.11 | Existing CKD, diabetes, dehydration, repeated contrast exposure. | Tell the imaging team about kidney disease and medications. |
| Chemotherapy agents | Rx | Cisplatin and related drugs can injure kidney tubules.12 | Cancer therapy, cumulative dose, other nephrotoxic medicines. | Oncology team should monitor kidney function. |
| Heroin / illicit opioids | Illicit | Can contribute to kidney injury through overdose complications, infections, and rhabdomyolysis.13 | Ongoing use, overdose, immobility, dehydration, injection-related infection. | Seek medical help; medically supervised detox may be safer than quitting alone. |
1. NSAIDs
NSAIDs like ibuprofen and naproxen are among the most common kidney-risk medications because they can reduce blood flow through the kidneys. NSAIDs can lead to acute kidney injury or worsening CKD, especially at higher doses or with long-term use.4 This does not mean every short-term dose is dangerous, but people with kidney disease, high blood pressure, heart disease, dehydration, or who use multiple medications should ask a clinician before using them. Some people use NSAIDs along with prescription painkillers. If you’re struggling with misusing prescription drugs, medical detox may help.
2. Certain antibiotics
Aminoglycoside antibiotics such as gentamicin can be kidney-toxic because they may injure the kidney’s tubule cells.2 These medicines are often used for serious infections, so the answer is not to stop treatment. The safer approach is to monitor kidney labs, make dose adjustments when needed, and communicate promptly with the prescribing clinician.
3. Diuretics
Diuretics help the body remove extra fluid and are often prescribed for blood pressure, heart, or kidney-related conditions. They can become risky when they contribute to dehydration or when combined with other medicines that affect kidney filtration.2 If you feel weak, dizzy, unusually thirsty, or notice major urine changes while taking a diuretic, call your prescriber.
4. Proton pump inhibitors
Proton pump inhibitors, or PPIs, are used for reflux and stomach acid conditions. They are not automatically harmful, but long-term use has been discussed in drug-induced kidney injury because some cases involve kidney inflammation.10 If you have been taking a PPI for a long time and are concerned or have noticed other signs of kidney damage, ask whether you still need it and whether kidney monitoring makes sense.
5. Certain antivirals
Some antivirals can affect the kidneys by forming crystals or injuring tubule cells, especially when dosing, hydration, or kidney function are not closely managed.2 People taking antivirals should tell their prescriber about kidney disease, dehydration, or other kidney-stressing medications. Do not stop an antiviral without medical guidance.
6. ACE inhibitors and ARBs
ACE inhibitors and ARBs, including lisinopril and losartan, can protect the heart and kidneys for many people. They can also change kidney filtration pressure and potassium balance, which is why lab monitoring matters.2 A temporary rise in creatinine may be expected in some cases, but only a clinician can interpret whether a change is safe.
7. Lithium
Lithium can be an effective psychiatric medication, but it requires blood-level and kidney monitoring. Lithium is among the medications linked with chronic kidney changes.2 Dehydration, dose changes, and interacting medicines can raise risk, so concerns should be handled with the prescribing clinician rather than by stopping abruptly.
8. Contrast dye
Contrast dye used in some imaging tests can stress the kidneys in people who already have kidney disease or other risk factors. Imaging teams often screen for kidney risk and may adjust the plan when needed.11 Tell your treatment team about pre-existing conditions, including CKD, diabetes, dehydration, recent illness, and all medications before the scan.
9. Chemotherapy agents
Some chemotherapy agents, including cisplatin, are known for kidney toxicity because they can injure kidney tubule cells.12 Your cancer team will weigh this risk against your treatment needs and may use different hydration, dose adjustments, and monitoring strategies to keep you safer. If you receive chemotherapy, tell your doctor or chemo team about reduced urination, swelling, severe nausea, or unusual weakness promptly.
10. Heroin and illicit opioids
Heroin and illicit opioids can harm the kidneys indirectly through overdose, low oxygen, severe dehydration, infections, and rhabdomyolysis. Research has linked narcotic-drug-related rhabdomyolysis with acute kidney injury, and heroin can add myotoxic (toxins that destroy muscle tissue) risk.13 If opioid use is ongoing, medically supervised detox and continued treatment can help stop use more safely.
Signs and symptoms of kidney damage
About 1 in 7 people has chronic kidney disease. Kidney damage symptoms may not be obvious at first.1 They can also overlap with symptoms of other health conditions. If you recognize risk factors in your lifestyle, talk to your doctor about testing and monitoring for kidney damage.
Possible signs to watch for:
- Peeing more or less than usual
- Swelling in the legs, feet, ankles, hands, or face
- Fatigue or weakness
- Nausea, vomiting, or appetite loss
- Dry or itchy skin
- Muscle cramps
- Trouble concentrating
- Foamy, bloody, or very dark urine
Seek urgent care if you have:
- Chest pain
- Trouble breathing
- Confusion
- Fainting
- Severe dehydration
- Very little urine
- Severe swelling
- Suspected overdose
If you think a prescribed medicine is affecting your kidneys, contact your doctor. If drug or alcohol use is involved, ask for help—especially if you have been using/drinking heavily or for a long time.
Can kidney damage be reversed?
Some acute kidney injuries can improve when the cause is found early and removed, but advanced, long-lasting CKD usually cannot be reversed. The best next step depends on the cause, severity, and whether the kidney stressor can be safely changed.3
For medication-related concerns, reversing course may mean adjusting the dose or type of medication, making lifestyle changes, or monitoring kidney labs. That decision belongs with you and your doctor. For substance-related concerns, stopping alcohol, opioids, stimulants, or misused prescriptions with medical detox support can help manage kidney damage.
When drug, alcohol, or substance use is damaging your kidneys
If ongoing substance use is contributing to kidney injury, quitting is important to managing your kidney health. However, withdrawal can be a risk in itself. Medical detox can help manage risks and keep you safe as you enter recovery.
Substance-related kidney damage rarely has one cause. Overdose, dehydration, overheating, seizures, infection, unknown contaminants, and high blood pressure are all common effects of drug use and can put strain on your kidneys.
- Opioids and heroin: Overdose-related low oxygen and prolonged immobility can combine with dehydration, infection, or rhabdomyolysis to cause acute kidney injury.3,13
- Cocaine and methamphetamine: Cocaine can cause intense vasoconstriction, severe hypertension, renal infarction, and rhabdomyolysis. Methamphetamine-related kidney injury may include acute tubular injury, protein in the urine, hypertensive vascular damage, and other issues.5,6
- Alcohol: Heavy use can disrupt fluid and electrolyte balance, contribute to dehydration and high blood pressure, and worsen kidney risk through liver disease or rhabdomyolysis.3,14 Alcohol can also cause liver damage.
- Polysubstance use: Combining opioids, stimulants, alcohol, benzodiazepines, or unknown substances can raise the risk of overdose, dehydration, and infection, which are risk factors for kidney damage.
Quitting drugs and alcohol can help you take better care of your kidneys. If you’ve been drinking or using drugs heavily or for a long time, there are risks with trying to detox at home. Entering an alcohol or drug addiction detox can be a safer way forward.

Frequently asked questions
Ibuprofen is an NSAID, and NSAIDs can reduce blood flow to the kidneys. The risk is higher with high doses, long-term use, dehydration, CKD, high blood pressure, or certain medication combinations.4 If you have kidney risk factors, ask a clinician before using ibuprofen regularly.
Metformin is not a common kidney toxin, but your doctor may consider your kidney function when recommending a dose. Your doctor may recommend eGFR monitoring as long as you take the medication.15 Do not stop your medication without medical guidance.
People with known kidney disease, abnormal kidney labs, dehydration risk, or heavy supplement use should ask a clinician before taking creatine. If symptoms or abnormal labs appear, testing is the only reliable way to know what is happening.
Lisinopril is an ACE inhibitor, a class that can affect kidney filtration pressure and potassium levels, so clinicians often monitor kidney labs.2 Ozempic and similar GLP-1 medicines are not common causes of kidney damage, but there is some emerging research that shows they may be associated with kidney injury.16
Acute kidney injury may improve when the cause is treated early. Advanced chronic kidney disease usually cannot be reversed, but it can often be slowed with treatment and risk reduction.1 The safest plan depends on testing and clinician guidance.
Do not stop a prescribed medication without talking to the prescriber. For alcohol, opioids, benzodiazepines, and some other substances, quitting suddenly can create withdrawal risks, so medically supervised detox may be safer.17 If symptoms feel urgent, seek emergency medical care.
