Is Tylenol Or Ibuprofen Worse For Your Kidneys

Unlike Ibuprofen and other NSAIDs, the active ingredient in Tylenol does not cause damage to the kidneys. In fact, the National KidneyFoundation recommends acetaminophen as the pain reliever of choice for occasional use in patients who have underlying kidney disease.

Although NSAIDs are more likely to cause kidney issues, Ibuprofen can still be used as long as it is not taken in excess. Unless otherwise directed by your physician, you should be just fine using Ibuprofen for occasional pain relief.

Which Painkiller Should You Pick

So which pain med reigns supreme? While theres no right answer, these pointers can help you decide.


Most research suggest acetaminophen and ibuprofen have similar results in controlling fevers, so pick what works for you.

Stomach trouble

If you have a sensitive stomach or find that ibuprofen causes heartburn or nausea, give acetaminophen a whirl.

Period pains

Ibuprofen reduces your bodys production of prostaglandins. These are the chemicals that trigger the uterus to contract and start periods each month. Ibuprofen can ease menstrual cramps and may also make menstrual bleeding lighter.

Other meds

Both ibuprofen and acetaminophen can interact negatively with some prescription and over-the-counter drugs. If youre taking medication, talk to your provider doctor or pharmacist before reaching for the painkillers.

Persistent pain

If youre taking painkillers over several days, consider alternating ibuprofen and acetaminophen to lower the risk of side effects.


Both ibuprofen and acetaminophen can control pain in kids. But ibuprofen tends to work better as a fever reducer. Be sure to follow the dosage guidelines on the label for your little ones age and weight.

Whats the takeaway? When used responsibly, ibuprofen and acetaminophen are safe choices for turning down the dial on fever and pain. And isnt it good to have options?

Nsaids Are Bad For Your Blood Pressure

NSAIDs can cause high blood pressure. And if you have high blood pressure, they can make it worse. This increases your chances of having a heart attack or a stroke.

NSAIDs can also keep some blood pressure drugs from working right. NSAIDs can interfere with:

  • Diuretics, or water pills, such as Hydrodiuril . Diuretics remove excess water from the blood vessels.
  • ACE inhibitors, such as Prinivil and Zestril . ACE inhibitors are drugs that relax the blood vessels.
  • ARBs such as Cozaar . ARBs are another group of drugs that relax the blood vessels.

Cox In Ureteral Obstruction And Lithium Nephropathy

Ibuprofen Pathway, Pharmacokinetics

The antidiuretic action of vasopressin depends on the exocytic insertion of AQP2 water channels from a store in intracellular vesicles to the apical plasma membrane of collecting duct principal cells, the so-called shuttle mechanism. Indomethacin markedly reduces the expression of AQP2 water channels in the collecting duct but enhances the shuttling of AQP2. The increased shuttling of APQ2 results in diminished urine volume. The altered urinary concentration ability and body water balance associated with the use of NSAIDs may in part be causally related with the alteration of AQP2 . Lithium treatment is one of the major causes of the acquired form of nephrogenic diabetes insipidus , a clinical syndrome in which the kidney is unable to concentrate urine despite normal or elevated concentrations of the antidiuretic hormone arginine vasopressin. In lithium-induced NDI rat models, downregulation of AQP2 has been demonstrated. For the treatment of NDI, NSAIDs or coxibs have been useful . The upregulation of AQP2 and the Na-K-2Cl inhibition underlies the therapeutic mechanisms by which COX-2 inhibitors enhance antidiuresis in patients with NDI .

Is Ibuprofen Bad For My Kidneys

While NSAIDs rarely affect the liver, they have important adverse effects on the kidney that you should know about. Here is the science behind the problem. Ibuprofen and other NSAIDs block prostaglandins, natural body chemicals that normally dilate blood vessels leading to the kidneys. Blocking prostaglandins may lead to decreased blood flow to the kidneys, which means a lack of oxygen to keep the kidneys alive. That can cause acute kidney injury.

A simple blood test may show a rise in creatinine if your kidneys are being affected, usually seen within the first three to seven days of NSAID therapy. Acute kidney injury can occur with any NSAID, though naproxen seems to be a bigger culprit. In one study, folks who took NSAIDs had twice the risk of acute kidney injury within 30 days of starting to take the NSAIDs. Good news is its reversible if you stop taking them.

Who is at risk? In people with high blood pressure, taking NSAIDs long-term may worsen underlying high blood pressure. Also, people with existing kidney problems more often get in trouble with NSAIDs. Regardless, if you are taking ibuprofen for long periods of time, its not a bad idea to have a check of your kidney function with a quick blood test. Remember, acute kidney injury from NSAIDs doesnt cause any symptoms.

Nonetheless, association between the exposure of NSAIDs and incident CKD has been questioned since the 1950s. The risk of developing CKD in relation to chronic use of NSAIDs remains inadequately explored.

As the researchers contended most evidence on this topic has mainly focused on the White population in the United States and Europe, it is important to examine the effects of NSAIDs in other populations, because Asians might be more susceptible to kidney failure when compared with Whites.

Therefore, using the Hong Kong Hospital Authoritys clinical database, Wan and colleagues included a cohort of individuals who had an eGFR of 60 mL/min/1.73 m2or greater between 2008 and 2017 .

Time To Onset Of Ibuprofen

We described the time to onsets of renal events for ibuprofen and APAP in Figure 2. According to the data, the median onset time of acetaminophen-related kidney injury was 2 days , and the median onset time of ibuprofen-related kidney injury was 5 days . Besides, there was a significant difference in average time to onset of renal events among ibuprofen and APAP . The average onset time of APAP-related kidney injury was 32.74 days, which was about a quarter of that of ibuprofen-related kidney injury .

What Are Nsaids Are They Safe To Take

Nonsteroidal anti-inflammatory drugs are a specific group of pain relievers. Some NSAIDs are available over the counter. This includes different brands of ibuprofen, naproxen sodium and ketoprofen.

NSAIDs are usually safe for occasional use when taken as directed, but if you have known decreased kidney function, they should be avoided. These medications should only be used under a doctor’s care by patients with kidney disease, heart disease, high blood pressure or liver disease or by people who are over 65 or who take diuretic medications. NSAIDs may cause an increased risk of sudden kidney failure and even progressive kidney damage.

Nsaids And Risk For Chronic Kidney Disease

Analgesic nephropathy is a slowly progressive chronic kidney disease resulting from daily use for many years of preparations containing at least two analgesics in combination with central-acting dependence-inducing substances, such as caffeine, codein, and/or barbiturates. Analgesic nephropathy is characterized by capillary sclerosis, renal cortical atrophy, chronic interstitial nephritis and/or papillary sclerosis/necrosis/calcifications. In a number of patients with analgesic nephropathy, the uroepithelia can develop transitional cell carcinoma. Analgesic nephropathy can be accurately diagnosed or excluded by computed tomography scanning without contrast media . Even if renal papillary necrosis occurs in patients with analgetic nephropathy, traditional NSAIDs including ibuprofen , tolmetin , indomethacin , benoxaprofen , and naproxen , have been also reported to cause renal papillary necrosis.

Gooch et al. determined the association between NSAID use and the progression of CKD in an elderly community-based cohort. A total of 10,184 subjects were followed for a median of 2.75 years. High-dose NSAID users was associated with an increased risk for rapid CKD progression among subjects with a baseline mean GFR between 60 and 89 mL/min/1.73 m² without risk differential between selective and nonselective NSAID users . Taken together, physicians should always prescribe the lowest effective dose of NSAIDs for the shortest possible time .

Whats The Difference Between Tylenol And Aspirin

Ibuprofen Pathway, Pharmacodynamics

âThe Healthy Geezerâ answers questions about health and aging in his weekly column.

Question: What is the difference between Tylenol and aspirin?

Answer: Acetaminophen is the most widely used pain-reliever and fever-reducer in the world. It is contained in more than 100 products.

Tylenol is the best known over-the-counter acetaminophen product. It is also a component of well-known prescription drugs such as Darvocet and Percocet. Acetaminophen also is known as paracetamol and N-acetyl-p-aminophenol .

There are basically two types of OTC pain relievers. Some contain acetaminophen, which is processed in the liver. Others contain non-steroidal anti-inflammatory drugs , which are processed elsewhere. Examples of OTC NSAIDs are aspirin, ibuprofen and naproxen sodium .

Taking too much acetaminophen can lead to liver damage. The risk for liver damage may be increased if you drink three or more alcoholic drinks while using medicines that contain acetaminophen.

Acetaminophen is one of the most common pharmaceutical agents involved in overdose, as reported to the American Association of Poison Control Centers.

NSAIDs are associated with stomach distress. You should talk to your doctor before using NSAIDS if you are over 60, taking prescription blood thinners, or have stomach ulcers or other bleeding problems.

Itâs a good idea for all older adults to consult their doctors before taking any OTC medication.

Expert Q& a: Safe Oa Medications For Kidney Health

Kidney problems can complicate your osteoarthritis treatment plan.

Question: My question concerns arthritis and kidney health. I haveosteoarthritis, but I cannot take many medications because I have kidney problems. Is there any treatment I could try that would not affect my kidneys? Answer: For patients with many types of arthritis,kidney problemscan indeed complicate treatment plans. If you have diminished kidney function, you may need to avoid nonsteroidal anti-inflammatory drugs , such as ibuprofen or naproxen , but there are many other options for arthritis and kidney patients. The first option is acetaminophen , which is an analgesic, not an NSAID.

Injections of hyaluronic acid compounds, which are designed to supplement a substance that gives joint fluid its viscosity, for example, may provide relief in affected joints without involving the kidneys. These products includeHyalgan,OrthoVisc,SupartzandSynvisc.

There are also topical products for arthritis that affects only one or two joints. A gel form of the prescription NSAID diclofenac is one option. Only a very small amount of the drug gets into the bloodstream, so it may be safe for your kidneys. However, topicals may not work well for hip pain, because the joint is too deep for the medication to penetrate.

Other nonprescription topicals include:

What Color Is Urine When Your Kidneys Are Failing

When kidneys are failing, the increased concentration and accumulation of substances in urine lead to a darker color which may be brown, red or purple. The color change is due to abnormal protein or sugar, high levels of red and white blood cells, and high numbers of tube-shaped particles called cellular casts.

Fatality Due To Ibuprofen

Compared with acetaminophen, ibuprofen is more potent, affects the elderly more, and occurs for a longer onset time on average, but the mortality rate is only one-sixth of that of ibuprofen . Maybe this anomaly is also related to their mechanisms. Acetaminophen-associated kidney injury is often accompanied by liver damage and AKI correlates with more severe liver injury in patients . In our research, liver injury as the most reported complication of kidney injury, far exceeds the second-ranked symptom of poisoning. Thus, the dysfunction of two important organs may occur simultaneously in a short period of time, which may overwhelm patients and eventually lead to death. However, ibuprofen-related kidney injury is more likely to occur over a long period of time, giving pharmacists and physicians more time to correct the renal dysfunction. In addition, in our study, the number of suicides using acetaminophen was significantly higher than that of ibuprofen . Based on this, the death rate of APAP-related kidney injury may increase due to the presence of more suicides. However, after excluding the suicide population, the mortality rate of APAP-related kidney injury is still significantly higher than that of ibuprofen, which means that the impact of suicide may not be as large as we thought.

Physiology And Pathophysiology Of Cox Inhibition

PGs regulate a wide variety of renal functions . PGE2 is considered to be mainly a tubular PG and PGI2 a vascular PG. However, renal arterioles, tubules, medullary interstitial cells, and mesangial cells are able to produce both PGE2 and PGI2. PGE2 regulates sodium and chloride transport in the loop of Henle and modulates water transport and renal medullary blood flow. The physiological effects of PG2 are mediated through the four G-protein-coupled transmembrane prostaglandin receptors EP1, EP2, EP3 and EP4. PGI2 regulates renal vascular tone, GFR and renin release . In a person with normal renal hemodynamic parameters, PGs do not play a dominant physiologic role in maintaining renal blood flow and GFR . Selective COX-2 inhibitors were developed to produce the beneficial effects of NSAIDs, but spare the COX-1-mediated adverse events . However, COX-2 appears to be associated with renal vascular tissues and podocytes and has been implicated as the dominant COX at the macula densa and in the medullary interstitium. The identification of constitutive COX-2 in the human kidney , and the recognition of the profound effects of PGs on renal homeostasis may indicate that COX-2 inhibitors have the same potential for adverse renal effects as traditional NSAIDs . Therefore, the same precautions in patients at risk for adverse renal effects probably apply to both the nonselective NSAIDs and COX-2 selective inhibitors .
