What are NSAIDs? Are they safe to take? – Nonsteroidal anti-inflammatory drugs (NSAIDs) 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.

Is paracetamol harmful to kidneys?

In general, paracetamol poisoning is associated with hepatotoxicity and very rarely with renal impairment in the absence of significant hepatic impairment. Paracetamol poisoning associated with renal impairment is rare, and it is mostly associated with hepatotoxicity. Most patients with acute renal impairment show a pattern of acute tubular necrosis or injury based on their blood, clinical presentation, and imaging.

The level of injury was found to be associated with the dose of paracetamol taken. We describe a case of a 22-year-old patient presenting to the hospital with abdominal pain, back pain, and two episodes of vomiting after 36 hours of an intentional paracetamol overdose of 60 tablets.

• His lab results showed raised creatinine levels and C-reactive protein (CRP) despite normal liver function tests.
• His paracetamol and salicylate levels were not checked on his initial presentation.
• He was given N-acetyl cysteine (NAC) treatment for paracetamol overdose and had computed tomography of kidneys, ureters, and bladder (CT KUB) the following day, which showed mild, uncomplicated sigmoid diverticula.

He was discharged the next day, but was readmitted two days later with severe abdominal pain and worsening renal function. He had an magnetic resonance imaging (MRI) abdomen that showed coronal/axial wedge like areas of relative hypo-intense change in the T2 acquisition.

He received intravenous fluids and antibiotics, and his renal function improved. He was discharged home with outpatient follow-up and appeared to be fully recovered. Keywords: paracetamol toxicity, : acute kidney injury, s: hepatotoxicity, nac- n acetyl cysteine, acute tubular necrosis (atn) Paracetamol poisoning is mainly associated with hepatotoxicity, and its association with renal impairment is rare.

The level of renal impairment risk is directly related to the dose of paracetamol taken. We describe a case of a 22-year-old patient presenting to the hospital with abdominal pain, back pain, and two episodes of vomiting after 36 hours of an intentional paracetamol overdose of 60 tablets (30 gram).

• His blood results showed raised creatinine levels and C-reactive protein (CRP) despite normal liver function tests on his initial presentation.
• However, his paracetamol and salicylate levels were not checked, despite the fact that he presented with a paracetamol overdose.
• He was given N-acetyl cysteine (NAC) treatment for paracetamol overdose and had a computerized tomography scan of his kidneys, ureters, and bladder (CT KUB) the following day that showed only mild, uncomplicated sigmoid diverticular disease.

He was discharged home a day after; however, he was readmitted two days later with severe abdominal pain and worsening renal function. He had magnetic resonance imaging (MRI) of his abdomen and pelvis on the second day of his second admission that showed coronal/axial wedge like areas of relative hypo-intense change in the T2 acquisition in both kidneys.

• He received intravenous fluids and antibiotics and his renal function improved.
• He was discharged home with outpatient follow up.
• Previous case reports have described the rare association of paracetamol overdose with renal failure and some of these patients require haemodialysis in the absence of any hepatic injury.

Most patients with acute renal impairment show a pattern of acute tubular necrosis or injury based on their blood, clinical presentation, and imaging. In our case report, this patient had normal liver function tests initially, although he had mildly deranged liver function tests at the time of discharge.

• The patient in our case report had normal liver function tests initially, but had mildly raised alanine aminotransaminase at the time of discharge.
• A 22-year-old patient with a past medical history of depression and no regular medications, presented to the emergency department with an intentional paracetamol overdose of 60 tablets (30 grams) after ingestion.

He initially presented to the emergency department with right iliac fossa and back pain in both renal angles associated with two episodes of vomiting early in the day. His initial blood tests showed mild acute kidney injury (AKI) with raised creatinine and high C-reactive protein, and his arterial blood gas (ABG) showed normal lactate.

Unfortunately, his paracetamol and salicylate levels were not checked on his initial presentation when he first presented to the hospital, and he received NAC treatment without getting paracetamol and salicylate levels. He received both NAC infusion and intravenous fluids on admission and patient was discharged home the following day after psychiatric assessment who deemed him to be at very low suicidal risk with further follow up in the community.

He had non-contrast CT KUB in view of the right loin and bilateral back pain that did not show any acute pathology apart from uncomplicated sigmoid diverticulosis. He returned two days later with worsening abdominal and back pain that was not responding to co-codamol.

He also had two small episodes of vomiting with rigors and was referred to the surgical team. His blood results showed worsening renal function, with creatinine rising from 126 two days ago to 196 today, and inflammatory markers were also raised, as shown in Table, His paracetamol and salicylate levels were less than 1 and 3, respectively, when checked on his second presentation to the hospital.

It is important to mention that the levels could be normal as he had received NAC treatment on his first presentation despite his levels not being checked. He had an ultrasound abdomen (US) followed by a non-contrast computerized tomography scan of his kidneys, ureters, and bladder that were reported to be normal.

1. The patient was also given fluids and painkillers, including co-codamol, and was also started on Ibuprofen by the surgical team, and medical review was requested.
2. The patient had received only two doses of Ibuprofen when he was reviewed by the medical team, and his Ibuprofen was stopped.
3. The patient had non-contrast magnetic resonance imaging of the abdomen and pelvis (MRI AP) on the second day of his admission that showed coronal/axial wedge like areas of relative hypo-intense changes in the T2 acquisition in both kidneys that could be due to infarction, inflammation, or infection as shown in Figures and 2.

His care was taken over by medical team in view of his worsening renal impairment and no obvious surgical issues. Blood results for patient during admission

1. He was reviewed by the pain team in view of his severe pain.
2. His ABG showed high bicarbonate at 34.1, normal lactate at 0.6 mmol/l, and normal pH at 7.35.
3. His midstream specimen of urine (MSU) showed muddy brown casts and his urine dip was positive for blood only.
4. His kidney functions continued to deteriorate, as shown in Table,

He was reviewed by the renal team, who diagnosed him with acute renal tubular necrosis secondary to paracetamol overdose based on his presentation, imaging, blood and urine results. He was treated with antibiotics and fluids and non-nephrotoxic painkillers such as oxycodone.

1. He started to respond to treatment on day 6 and his kidney functions showed improvement.
2. His renal and autoimmune screens were negative, which was requested on advice of the nephrologist.
3. It is important to mention here that he was not dehydrated as his urea was slightly raised on his first presentation to the hospital, but his lactate was normal.

When he presented himself a second time to the hospital, his urea and lactate were both normal, which essentially rules out dehydration as a cause, and clinically he was euvolemic. He stayed in the hospital for eight days and showed a good physical and biochemical response to treatment, and his blood improved significantly, as shown in Table,

The patient was discharged home with follow-up in a month’s time, and he showed complete resolution of symptoms. The current report presents a rare phenomenon seen in patients with paracetamol toxicity who present with acute renal impairment in the absence of liver impairment. Previous case reports have described the rare association of paracetamol overdose with renal failure, and some of these patients require haemodialysis in the absence of any hepatic injury,

A few cases of paracetamol-induced renal injury in the absence of hepatic failure have been reported, and a few of these case reports are in young children younger than 18 years old. Nephrotoxicity with paracetamol without hepatotoxicity is rare and is mostly reversible.

The reported incidence of renal toxicity due to paracetamol is 1-2% in most studies, except for a few studies in which it has been reported to be up to 8.9%, There was no obvious predictor for this complication due to paracetamol being found and serial blood tests in children were advised, Another case report of a 15-year-old Vietnamese female who ingested 50-60 325 mg paracetamol tablets and presented to the emergency department 15 hours after the ingestion of the tablets with nausea, mild upper right abdominal and right flank pain.

Her paracetamol level was 181 µmol/l and the level was 33 µmol/l following the NAC infusion. Her initial creatinine was 68 µmol/l and her urea was 4.6 mmol/l. Her creatinine began to rise on day 2 and reached 168 µmol/l on day 3 and fell to 90 µmol/l on day 5.

• Renal impairment due to paracetamol has been described in previous studies and is attributed to acute tubular necrosis both clinically and histologically.
• The possible explanation for this nephrotoxicity is similar to hepatotoxicity caused by the metabolism of paracetamol by the P450 enzyme system.
• The patient in our case did not have levels checked due to late presentation (36 hours) to the ED and had a degree of renal impairment on presentation and was treated with NAC.

The creatinine level was raised to 196 µmol/l in our patient before its decline, One case series reported delayed presentation of renal failure due to significant paracetamol overdose in patients about 48 hours prior to presentation, A few published case reports have shown both hepatotoxicity and nephrotoxicity to be present in patients with paracetamol overdose.

One such case report is based on the presentation of a 39-year-old patient with schizoaffective and bipolar disorder who took over 100 grams of paracetamol two days prior to his presentation to the emergency department with right upper quadrant pain, nausea, and vomiting. This patient initially had hepatotoxicity due to paracetamol and was treated with NAC.

However, this patient started to develop renal impairment on day 3 and, despite improvement in his liver functions, his renal functions continued to deteriorate. His creatinine increased from 0.6 mg/dl on day 1 to 5.7 mg/dl on day 5, and his urea increased from 18 mg/dl to 40 mg/dl on day 5.

The likely aetiologies considered were acute tubular necrosis; however, it was excluded as the patient did not have any evidence of hypovolemia or poor perfusion, and this was evidenced by normal blood pressure and normal lactic acid levels in this patient. Hepatorenal syndrome was unlikely as this patient did not have any evidence of hepatic encephalopathy and normal liver function.

The most likely aetiology was acute tubular injury secondary to paracetamol. This patient continued to deteriorate and developed confusion and asterixis consistent with uraemia. The patient underwent haemodialysis on days 10 and 11. His renal functions continued to improve thereafter, and his creatinine was 1.32 mg/dl on discharge.

The patient in our case report fortunately did not require dialysis and his renal functions showed improvement during admission to treatment, A case series report suggested that renal impairment in patients with paracetamol overdose seems to be unrelated to the degree of liver injury, and NAC treatment did not seem to contribute to the nephrotoxicity.

Nine patients had renal dysfunction in this group, and two patients required dialysis who were both comatose, severely hypotensive, and acidotic, and one patient from this group died post-dialysis. The other seven patients showed improvement in their renal functions without dialysis in two to seven days’ time.

1. A total of eight patients received NAC from these nine patients, and a total of six patients received NAC from the group of seven patients who did not require dialysis.
2. They reported that patients with renal impairment tend to be younger and have higher AST levels and lower mean paracetamol levels.
3. The patient in our case report had normal liver function initially, but he developed mild liver impairment over the next two to three days with worsening renal function.

However, his renal functions showed improvement on day 7 and continued to improve till his date of discharge from the hospital, The etiology of renal impairment in our patient is most likely due to paracetamol poisoning, as there was no other obvious cause identified for his renal impairment.

In addition, his blood results and imaging findings were in keeping with paracetamol-induced acute tubular necrosis. He had normal urea and lactate on his second presentation, and although he was feeling nauseous, he was managing to eat and drink and was not dehydrated. Renal impairment due to paracetamol is due to tubular cell loss, which is a characteristic feature of both acute renal failure and chronic renal disease and is particularly noticeable when apoptosis predominates over mitosis,

Paracetamol has been shown to promote hepatocyte apoptosis, and apoptosis generally provides an opportunity for treatment. However, the mechanism for renal cell death and the mode of apoptosis in patients with paracetamol overdose is not clear, and there is evidence that the molecular basis of paracetamol-induced nephrotoxicity may differ from those of hepatotoxicity, as N-acetyl-cysteine protects from the latter, but has been shown not to protect from nephrotoxicity,

Our patient did not have any urinary symptoms at all and was apyrexial, which makes acute pyelonephritis very unlikely. With larger case series, it may be possible to explore this problem even more and predict the exact incidence of nephrotoxicity alone and combined hepatotoxicity and nephrotoxicity due to paracetamol toxicity.

A case series based on 2068 patients with paracetamol poisoning between March 2005 and October 2007 reported the incidence of acute renal failure due to paracetamol to be only 0.4%, and most patients had hepatotoxicity. Renal failure in these patients was defined by a serum creatinine concentration ≥150 µmol/L (1.69 mg/dL) or ≥50% increase from baseline, and serum creatinine concentrations and alanine aminotransferase (ALT) activity were considered with respect to the interval after paracetamol ingestion.

Peak serum ALT activity occurred 2.5 days (2.2-2.9 days) after ingestion, but peak serum creatinine concentrations did not occur until 5.5 days (4.4-5.9 days) after ingestion (p = 0.031 by Wilcoxon test).Renal replacement therapy was not required in these patients, and renal function slowly returned to normal.

The authors highlighted, based on this case series, that rising serum creatinine concentrations only became detectable after more than 48 hours after paracetamol ingestion, and therefore, renal failure can easily be missed in these patients if they are discharged home early,

Further studies are required to understand the exact prevalence of paracetamol-induced nephropathy alone. In conclusion, it is important to remember that paracetamol toxicity can present with acute renal impairment in the absence of liver damage, and these patients should be properly treated to prevent them from developing chronic renal failure.

NAC has no role in the management of acute kidney injury in patients due to paracetamol overdose. Imaging should always be considered in these patients as they tend to present with abdominal pain and other abdominal emergencies that need to be ruled out.

Acute tubular necrosis shows good recovery when the underlying insult is corrected and euvolemic status is maintained. It may take one to three weeks for these patients to show complete recovery. It is also important to be aware of the delayed presentation of patients with acute renal failure due to paracetamol overdose, particularly in higher doses, as this can be easily overlooked.

Is Tylenol or ibuprofen safer for kidneys?

Ibuprofen is harder on the kidneys than acetaminophen. Acetaminophen doesn’t have the same effect on the COX pathway as ibuprofen. So kidney damage is much more rare. Kidney issues are typically only reported when a person has taken too much acetaminophen.

What is the safest anti-inflammatory for kidneys?

Kidney problems can complicate your osteoarthritis treatment plan. Question: My question concerns arthritis and kidney health. I have osteoarthritis (OA), 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 problems can indeed complicate treatment plans.

1. If you have diminished kidney function, you may need to avoid nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen ( Advil, Motrin ) or naproxen ( Aleve, Naprosyn ), but there are many other options for arthritis and kidney patients.
2. The first option is acetaminophen ( Tylenol ), 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 (usually knees) without involving the kidneys. These products include  Hyalgan,  OrthoVisc,  Supartz  and  Synvisc,

1. There are also topical products for arthritis that affects only one or two joints.
2. A gel form of the prescription NSAID diclofenac ( Voltaren Gel ) is one option.
3. 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.

The most effective of the over-the-counter products are those containing capsaicin ( Capzasin, Salonpas Hot  and  Zostrix ). Derived from hot chili peppers, capsaicin has been found to reduce a chemical in the body that transmits pain signals. Other nonprescription topicals include:

Counterirritants, which include ingredients such as menthol and camphor ( Biofreeze and JointFlex ). These provide a mild cooling sensation that distracts from underlying pain. Salicylates, which are related to aspirin and relieve pain directly, include products such as  Aspercreme  and  Myoflex, Combination products may contain ingredients such as methyl salicylate and menthol (mentholatum cream,  BenGay ), or capsaicin, salicylates and a counterirritant ( Heet   liniment).

Of course, there are several nondrug treatments, too, that would be completely safe for your kidneys. These include using a brace or cane, using heat and cold therapy, taping a joint, going to physical therapy  and trying acupuncture, Don Miller, PharmD Professor, Department of Pharmacy Practice  North Dakota State University Fargo, North Dakota

Which painkillers damage the kidneys?

What is analgesic nephropathy? – Analgesics are painkillers. Examples include:

Aspirin Acetaminophen Ibuprofen Naproxen sodium

Taking one or a mix of these medicines daily over a long time may cause chronic kidney problems. This is called analgesic nephropathy. Painkillers that combine 2 or more medicines (such as, aspirin and acetaminophen together) with caffeine or codeine are the most likely to harm the kidneys. Painkillers with codeine require a prescription.

Which painkiller does not affect kidneys?

What analgesics are safe for people who have kidney disease? – Acetaminophen remains the drug of choice for occasional use in patients with kidney disease because of bleeding complications that may occur when these patients use aspirin. However, kidney patients who need to use acetaminophen habitually should be supervised by their doctors and be sure to avoid drinking alcohol while on this medicine.

What drugs are toxic to kidneys?

Illegal Drugs – Most street drugs, including heroin, cocaine and ecstasy can cause high blood pressure, stroke, heart failure and even death, in some cases from only one use. Cocaine, heroin and amphetamines also can cause kidney damage.

Is Panadol safe for kidneys?

What are the different types of pain killers? – Paracetamol in standard doses is safe to take if you have kidney problems. Opioids can be used carefully starting with small doses and increasing the dose slowly if required and only under medical supervision.

What can I take instead of ibuprofen for kidney patients?

If you have kidney problems – But for people with kidney disease, aspirin can increase the risk of bleeding. And in those with reduced kidney function, aspirin is not recommended unless prescribed by a physician. The recommended alternative can vary depending on the type and severity of kidney problems that you have.

What is the most kidney friendly NSAID?

Study: Ibuprofen Found Safest NSAID for the Kidney Exposure to nonsteroidal anti-inflammatory drugs (NSAIDs) is associated with higher risks for an incident estimated glomerular filtration rate (eGFR, in mL/min/1.73 m 2 ) below 60 and an eGFR decline of 30% or greater, investigators reported in the Clinical Journal of the American Society of Nephrology,

1. The study examined the effect of 9 oral NSAIDs on kidney function in a retrospective cohort of 1,982,488 Chinese individuals in Hong Kong aged 18 years or older with an eGFR higher than 60.
2. Overall, NSAID treatment — defined as a prescription for NSAIDs for a minimum of 28 days — was significantly associated with a 71% increased risk of incident eGFR less than 60, 93% increased risk of an eGFR decline of 30% or greater, and 88% increased risk of the composite of either outcome compared with no NSAID use, Eric Yuk Fai Wan, MD, of The University of Hong Kong, and colleagues reported.

Ibuprofen was the safest NSAID, conferring a significant 12% increased risk of incident eGFR less than 60, 32% increased risk of an eGFR decline of 30% or greater, and 34% increased risk of the composite outcome. Etoricoxib had the largest negative effect on kidney function.

Its use was significantly associated with a 3.1-fold increased risk of both incident eGFR less than 60 and eGFR decline of 30% or greater as well as the composite of either outcome. The incidence rates for an eGFR less than 60, an eGFR decline of 30% or greater, and the composite outcome were 33.0, 62.1, and 68.0 cases per 1000 person-years, respectively, for any NSAID use compared with 22.8, 33.4, and 36.8 per 1000 person-years for no NSAID use.

For the study, Dr Wan and colleagues used the clinical database maintained by the Hong Kong Hospital Authority, which manages the public health care sector in Hong Kong. Individuals in the study had an average age of 55 years, and 47% were men. The investigators limited their analysis to 154,991 individuals who used NSAIDs and 1,734,701 who did not.

• During a median follow-up duration of 6.3 years, 271,848 cases of incident eGFR less than 60 and 388,386 events of an eGFR decline of 30% or greater occurred.
• The other NSAIDs included in the study were celecoxib, diclofenac, indomethacin, mefenamic acid, naproxen, piroxicam, and sulindac.
• With regard to study limitations, the investigators explained that the database they used for the study did not cover all NSAIDs available in Hong Kong because of formulary restrictions.

In addition, the study did not capture over-the-counter NSAID use and did not take into account patients’ drug adherence, which could vary among NSAID users, the investigators pointed out. Reference Wan EYF, Yu YET, Chan L, et al. Clin J Am Soc Nephrol,

What pain meds don’t affect liver and kidneys?

What painkiller does not affect the liver? – Acetaminophen (paracetamol), when taken in reduced doses (maximum 2–3 grams per day), is generally considered to be the safest pain relief option for your liver. However, high doses may cause liver damage, so it’s important to stay under the safe limit.

Can kidneys recover from NSAID damage?

Do NSAIDs Cause Kidney Injury? | Ochsner Health Non-steroidal anti-inflammatory drugs, or NSAIDs, are medications that help to reduce inflammation. They also control pain and fever and are available over the counter and by prescription. Common NSAIDs include ibuprofen (Advil, Motrin), aspirin (Bayer), and naproxen sodium (Aleve).

These drugs are typically safe if they are used infrequently, but for people with decreased or chronic kidney disease, they should be avoided. Are NSAIDs safe to take? NSAIDs are typically safe to use. However, many patients are sensitive to the side effects of these medications, even with normal kidney function.

If you have reduced kidney function or have a number of other medical conditions, you may be much more likely to have problems with taking these drugs. NSAIDs can affect kidneys by several different mechanisms. They can cause high blood pressure and can also interact with some blood pressure drugs in a way that prevents them from working correctly such as diuretics, ACE inhibitors, and ARBs which are a group of drugs that are designed to relax blood vessels.

• NSAIDs may increase your fluid retention and can lead to decreased blood flow to kidneys.
• This is because NSAIDs block prostaglandins, which are the natural chemicals that dilate blood vessels and allow oxygen to reach the kidneys to keep them alive and healthy.
• Can you take NSAIDs if you have kidney disease? NSAIDs generally should be avoided in patients who have advanced kidney disease.

In some circumstances, NSAIDs can be used for a short period of time in patients with mild to moderate If these medications are used, doctors will monitor for side effects by checking blood tests more frequently. In one study, people who took NSAIDs showed double the risk of acute kidney injury within 30 days of starting the medication.

Is kidney damage caused by NSAIDs reversible? The damage that is caused by these medications can be reversible if the drug is stopped, but there is also a chance that the damage will not be able to be reversed. In some cases, the damage is so severe that it will cause the patient to need dialysis. Are there other options? Safer options for patients with chronic kidney disease include acetaminophen (Tylenol) or aspirin.

Tylenol does not treat inflammation, but it can help both pain and fever. While aspirin is an NSAID, in low doses, it does not pose a significant risk to, Are there other side effects from taking Aspirin and Tylenol? Other side effects of Tylenol include liver disease as well as issues with patients on blood thinners.

What does kidney pain feel like?

What does kidney pain feel like? – Kidney pain often feels like a dull ache that gets worse if someone gently presses on that area. While it is more common to feel kidney pain on only one side, some health problems may affect both kidneys and cause pain on both sides of your back.

What is a strong painkiller without side effects?

What is the safest painkiller to use? Paracetamol tends to have fewer side-effects than other over-the-counter painkillers. Ibuprofen and aspirin can cause stomach problems. Paracetamol is often better for people with conditions that cause bleeding.

How much paracetamol is safe for kidneys?

Weak opioids e.g. codeine – These medications are usually taken every four-six hours, with a maximum of six doses in 24 hours. People with kidney disease often only need very small doses of opioids and often get more side effects even with a small dose.

Does paracetamol damage liver or kidneys?

– PubMed Paracetamol is a widely known over-the-counter analgesic and antipyretic which, in acute poisoning usually causes liver damage, and less commonly damage to the kidney, heart, and pancreas. In the present paper we report a case of acute suicidal paracetamol intoxication complicated by acute hepatic and renal failure.

1. The discussion covers the pathogenesis, clinical course, and treatment of acute renal failure in the course of paracetamol poisoning.
2. Case report: A thirty-four-year-old woman was admitted to hospital in the second day after ingestion of nearly 17 g of acetaminophen.
3. During admission to the hospital, the maximum values of transaminases (AST 19 350 U/L, ALT 11 760 U/L) were found; they have gradually normalized over the next few weeks.

Sequentially monitored serum creatinine showed an upward trend, reaching a value of 588 micromol/L in the fifth day after drug ingestion. The patient underwent 1 haemodiafiltration and 4 haemodialysis treatments resulting in an improvement in renal function.

1. Conclusions: In acute acetaminophen poisoning, in addition to standard monitoring of liver function, the monitoring of kidney function is necessary because of the risk of acute renal failure due to acute tubular necrosis.
2. Idney damage is likely to be transient and generally will not need long-term renal replacement therapy.

Is paracetamol safe for liver and kidneys?

Key facts –

Paracetamol is a medicine used to treat mild to moderate pain. Paracetamol can also be used to treat fever (high temperature). It’s dangerous to take more than the recommended dose of paracetamol. Paracetamol overdose can damage your liver and cause death. Always follow the directions on the packet when using paracetamol.

Is paracetamol bad for kidney or liver?

Is it safe? – Safety boils down to examining really bad things happening to a very small number of people who take a drug. Unless the rate of the very bad thing is vanishingly small, the authorities won’t let us buy the drug from a petrol station. If we want to study those rare events, then we need study large numbers of people.

1. Partly because paracetamol is such an old drug these studies have largely not been done until recently.
2. Those we have tell us that paracetamol use is associated with increased rates of death, heart attack, stomach bleeding and kidney failure.
3. Paracetamol is known to cause liver failure in overdose, but it also causes liver failure in people taking standard doses for pain relief.

The risk is only about one in a million, but it is a risk. All these different risks stack up.
