## **Understanding How Your Kidneys Work**

Before we get into specific medicines and risks, it helps to understand what your kidneys actually *do*.

Your two kidneys are bean‑shaped organs located in your lower back. Every day, they filter about **150–180 liters of blood**, removing waste products and excess fluids to make urine. They also:

* Regulate blood pressure

* Maintain electrolyte balance

* Produce hormones that help your bones and blood cells

* Filter toxins, drugs, and metabolic by‑products from your bloodstream

Because kidneys are so busy, any reduction in their function — even small — can have widespread effects on your body. And unlike some organs, **kidney damage often progresses silently** — you may not feel symptoms until a large portion of renal function is already compromised.

This is exactly why medication‑induced kidney strain is so important to understand. ([Institut national du diabète et des maladies digestives et rénales][1])

## **Medications That Can Affect Kidney Function**

### **1. NSAIDs (Non‑Steroidal Anti‑Inflammatory Drugs)**

This group is one of the *most widely used* over‑the‑counter (OTC) medications in the world — and one of the most common contributors to kidney stress.

**NSAIDs** include:

* Ibuprofen (Advil, Motrin)

* Naproxen (Aleve)

* Aspirin in higher doses

* Prescription NSAIDs like diclofenac, celecoxib, meloxicam, indomethacin, oxaprozin, and others

These drugs *reduce inflammation, pain, and fever* — which is why many people take them daily for chronic pain, headaches, menstrual cramps, or arthritis.

But here’s the catch: **NSAIDs work by inhibiting prostaglandins** — substances that help *keep blood vessels around the kidneys dilated* so blood can flow freely. With prostaglandins blocked, kidney blood flow can drop, leading to:

* Reduced filtration

* Acute kidney injury (especially when dehydrated)

* Cumulative stress that can lead to chronic kidney dysfunction if used long‑term daily

This is true even for otherwise healthy adults. ([Institut national du diabète et des maladies digestives et rénales][1])

**Key take‑aways about NSAIDs:**

* Daily use for pain or inflammation over many weeks or months can stress your kidneys. ([Healthline][2])

* Taking NSAIDs while dehydrated or with other medications that also affect kidney circulation greatly increases the risk. ([Institut national du diabète et des maladies digestives et rénales][1])

* For people with existing kidney disease, diabetes, heart disease, or high blood pressure, doctors often *avoid* NSAIDs unless absolutely needed. ([National Kidney Foundation][3])

* Even OTC status doesn’t guarantee safety — NSAIDs can cause *acute kidney injury* when misused. ([National Kidney Foundation][3])

👉 **If you take NSAIDs frequently for pain relief, talk to your doctor about safer alternatives or strategies to minimize kidney impact.**

### **2. Some Antibiotics**

Antibiotics that are cleared from your body through the kidneys can *build up* if your kidney function is reduced — and in some cases may themselves contribute to kidney damage.

Common examples include:

* Penicillins

* Cephalosporins

* Certain sulfa antibiotics

These are typically safe when prescribed at proper doses, but if:

* You take leftover antibiotics without a prescription

* You continue antibiotics beyond the prescribed duration

* You double‑up doses, or don’t finish a course properly

…then the risk of antibiotic‑related stress on your kidneys increases. The kidneys have to filter the *by‑products* and metabolites of these drugs — and that can add extra strain. ([Cleveland Clinic][4])

👉 Always *finish your prescribed course* and *never self‑prescribe antibiotics*. If you have kidney issues or reduced function, your doctor may adjust the dosage. ([Cleveland Clinic][4])

---

### **3. Proton Pump Inhibitors (PPIs)**

PPIs are medications used for:

* Acid reflux

* Heartburn

* Gastric ulcers

Examples include:

* Omeprazole (Prilosec)

* Lansoprazole (Prevacid)

While they are effective and widely used, **long‑term use has been linked to an increased risk of kidney disease** in some studies. These drugs don’t damage kidneys in the same way NSAIDs do, but prolonged use (especially at high doses) appears associated with higher risk of chronic kidney issues. ([Healthline][5])

👉 If you’re taking PPIs daily for months or years, discuss whether you still need them or if other options are safer for your renal health.

### **4. Blood Pressure Medications**

Drugs like:

* ACE inhibitors (e.g., lisinopril, enalapril)

* ARBs (e.g., losartan, valsartan)

…are often prescribed *to protect the kidneys* — especially in diabetes and hypertension. But they can also alter blood flow dynamics in the kidneys. This can be beneficial in many cases but occasionally requires careful monitoring.

In some situations, these medications may lead to reduced filtration pressure, which needs medical follow‑up with labs to ensure your kidneys are coping well. **Never stop these drugs on your own** — but do *review their impact regularly with your doctor*. ([Healthline][5])

---

### **5. Diuretics (“Water Pills”)**

Diuretics like furosemide (Lasix) or hydrochlorothiazide help your body eliminate excess salt and water — useful for:

* High blood pressure

* Edema

* Heart failure

However, because they work on the kidneys to increase urine output, they *put extra load on renal function* and can change fluid and electrolyte balance. In some cases, this can reduce kidney blood flow and contribute to damage if not monitored. ([CROQ Kilos][6])

👉 Your doctor should tailor your dose based on labs and overall health.

---

### **6. Certain Supplements and Herbal Remedies**

Surprisingly to many people, **dietary supplements and “natural” products can also harm kidneys**, especially if taken without medical guidance.

Many supplements are **not tightly regulated**, meaning they can contain ingredients that:

* Interact with prescription drugs

* Affect kidney filtration

* Alter electrolyte balance

* Mask kidney stress symptoms

Examples of supplements linked to renal issues in some cases include herbal products, high‑dose vitamin C (over 500 mg), or products with hidden ingredients that impact blood pressure or metabolism. ([Cleveland Clinic][4])

👉 Always *tell your doctor or pharmacist* about every supplement you take — even if it’s “natural.”

## **Who Is at Greater Risk?**

While anyone can experience medication‑related kidney stress, some people are at **higher risk**:

✔ Older adults

✔ People with existing kidney disease

✔ Those with diabetes

✔ Individuals with high blood pressure or heart disease

✔ People taking multiple medications

✔ Those who use NSAIDs regularly

These conditions can interact with medications to lower kidney function more easily or accelerate damage over time. ([National Kidney Foundation][3])

## **Symptoms Your Kidneys Might Be Struggling**

Kidney damage often develops gradually and silently — but some signs may show up *before* significant harm occurs:

🟠 Fatigue and weakness

🟠 Changes in urination (frequency, color, foamy urine)

🟠 Swelling in ankles, feet, or face

🟠 Persistent nausea or loss of appetite

🟠 Difficulty concentrating

🟠 Muscle cramps

🟠 Unexplained itching

If you notice any of these symptoms — especially if you’re regularly taking medications known to impact kidneys — consult your doctor promptly.

## **Why Consulting Your Doctor Matters**

Because kidney health is complex, the most important takeaway is this:

> **Never ignore the possibility that your medications — even OTC ones — could affect your kidneys. Discuss them with a doctor or pharmacist.**

Your physician can:

* Review all current medications and supplements

* Recommend safer alternatives

* Adjust doses based on kidney function tests

* Order lab work (like creatinine and eGFR) to monitor kidney health

* Help you recognize early signs of harm

Kidney damage that is caught early often *can be halted or even reversed* if the offending medication is stopped or changed.

## **Medication Safety Myths and Facts**

**Myth:** “OTC means safe for everyone.”

**Fact:** OTC does not guarantee safety — and medications like NSAIDs can harm kidneys especially when overused. ([Institut national du diabète et des maladies digestives et rénales][1])

**Myth:** “Only prescription drugs impact kidneys.”

**Fact:** Many OTC painkillers, antibiotics, PPIs, supplements, and herbal products can affect renal function. ([Cleveland Clinic][4])

**Myth:** “I’d feel symptoms if my kidneys were affected.”

**Fact:** Early kidney damage often shows no obvious symptoms — that’s why monitoring and doctor consultations are critical.

## **Conclusion: Your Kidneys Deserve Attention**

Your kidneys are vital — but too often, their health is overlooked until a crisis hits. With millions of people taking NSAIDs, antibiotics, supplements, and other medications every day, the potential for silent kidney stress is real. What may feel like a harmless daily routine could be impacting kidney function without you realizing it.

If you’re taking any medication — prescription or OTC — especially regularly or long‑term, **consult your doctor**. Review your medications, get your kidney function tested, and make adjustments where necessary. The earlier you take action, the better your chances of avoiding irreversible kidney damage.

**Your kidneys work tirelessly for you every day — it’s time to give them the attention they deserve.**
