Fatal Metformin Overdose: Case Report And Postmortem Biochemistry Contribution

Fatal Metformin Overdose: Case Report And Postmortem Biochemistry Contribution

Abstract Metformin is an oral antihyperglycemic agent used in the management of type 2 diabetes mellitus. Lactic acidosis from metformin overdose is a rare complication of metformin therapy and occurs infrequently with therapeutic use. Fatal cases, both accidental and intentional, are extremely rare in clinical practice. Metformin is eliminated by the kidneys, and impaired renal function can result in an increased plasma concentration of the drug. In this report, we describe an autopsy case involving a 70-year-old woman suffering from diabetes mellitus and impaired renal function who received metformin treatment. Metformin concentrations in the peripheral blood collected during hospitalization and femoral blood collected during autopsy were 42 and 47.3 µg/ml, respectively. Lactic acidosis (29.10 mmol/l) was objectified during hospitalization. Furthermore, postmortem biochemistry allowed ketoacidosis to be diagnosed (blood β-hydroxybutyrate, 10,500 µmol/l). Death was attributed to lactic acidosis due to metformin intoxication. Increased plasma concentrations of the drug were attributed to severely impaired renal function. The case emphasizes the usefulness of performing exhaustive toxicology and postmortem biochemistry towards the more complete understanding of the pathophysiological mechanisms that may be involved in the death process.

Lactic Acidosis Secondary To Metformin Overdose: A Case Report

Lactic Acidosis Secondary To Metformin Overdose: A Case Report

Timbrell et al.; licensee BioMed Central Ltd.2012 Metformin is a commonly used treatment modality in type 2 diabetes mellitus, with a well documented side effect of lactic acidosis. In the intensive care setting lactate and pH levels are regularly used as a useful predictor of poor prognosis. In this article we highlight how high lactate levels are not an accurate predictor of mortality in deliberate metformin overdose. We present the case of a 70-year-old Caucasian man who took a deliberate metformin overdose of unknown quantity. He had a profound lactic acidosis at presentation with a pH of 6.93 and a lactate level of more than 20mmol/L. These figures would normally correspond with a mortality of more than 80%; however, with appropriate management this patients condition improved. We provide evidence that the decision to treat severe lactic acidosis in deliberate metformin overdose should not be based on arterial lactate and pH levels, as would be the case in other overdoses. We also demonstrate that appropriate treatment with hemodiafiltration and 8.4% sodium bicarbonate, even in patients with a very high lactate and low pH, can be successful. MetforminLactate LevelLactic AcidosisArterial LactateCritical Care Patient Metformin is a biguanide typically used as a first line drug for the treatment of type 2 diabetes mellitus. Its chief modes of action are reduced absorption of glucose from the gastrointestinal tract, decreased hepatic gluconeogenesis and increased peripheral utilization of glucose[ 1 ]. All of these actions lower plasma levels of glucose. Commonly reported side effects are predominantly gastrointestinal and include: nausea, vomiting and abdominal pain. Lactic acidosis is a well-recognized consequence of toxicity and is often associated with concurrent Continue reading >>

Metformin Overdose

Tweet Save As with any medication, it is possible to overdose on metformin. Some of the effects of a metformin overdose may include low blood sugar or lactic acidosis. Symptoms of low blood sugar include blurred vision, shakiness, and extreme hunger. Some symptoms of lactic acidosis can include an irregular heartbeat, trouble breathing, and feeling tired. There are some treatment options for a metformin overdose, including dialysis or using a sugar solution to increase blood sugar levels. Metformin Overdose: An Overview Metformin (Glucophage®) is a prescription medication that has been licensed to treat type 2 diabetes. As with all medicines, it is possible to take too much metformin. Effects of a metformin overdose will vary depending on a number of factors, including how much metformin was taken and whether it was taken with any other medicines, alcohol, and/or drugs. If you happen to overdose on metformin, seek medical attention immediately. Symptoms of a Metformin Overdose The effects of a metformin overdose may include: Possible symptoms of low blood sugar include: Sweating Shakiness Extreme hunger Dizziness Cold sweats Blurry vision.

Metformin

Metformin, marketed under the trade name Glucophage among others, is the first-line medication for the treatment of type 2 diabetes,[4][5] particularly in people who are overweight.[6] It is also used in the treatment of polycystic ovary syndrome.[4] Limited evidence suggests metformin may prevent the cardiovascular disease and cancer complications of diabetes.[7][8] It is not associated with weight gain.[8] It is taken by mouth.[4] Metformin is generally well tolerated.[9] Common side effects include diarrhea, nausea and abdominal pain.[4] It has a low risk of causing low blood sugar.[4] High blood lactic acid level is a concern if the medication is prescribed inappropriately and in overly large doses.[10] It should not be used in those with significant liver disease or kidney problems.[4] While no clear harm comes from use during pregnancy, insulin is generally preferred for gestational diabetes.[4][11] Metformin is in the biguanide class.[4] It works by decreasing glucose production by the liver and increasing the insulin sensitivity of body tissues.[4] Metformin was discovered in 1922.[12] French physician Jean Sterne began study in humans in the 1950s.[12] It was introduced as a medication in France in 1957 and the United States in 1995.[4][13] It is on the World Health Organization's List of Essential Medicines, the most effective and safe medicines needed in a health system.[14] Metformin is believed to be the most widely used medication for diabetes which is taken by mouth.[12] It is available as a generic medication.[4] The wholesale price in the developed world is between 0.21 and 5.55 USD per month as of 2014.[15] In the United States, it costs 5 to 25 USD per month.[4] Medical uses[edit] Metformin is primarily used for type 2 diabetes, but is increasingly be Continue reading >>

Metformin Overdose: An Unusual Cause Of Severe Metabolic Acidosis Singh Y, Joshi Sc, Tayal I, Sharma N - Chrismed J Health Res

Metformin is commonly used in the treatment of type 2 diabetes mellitus (DM). Severe lactic acidosis is a rare side effect of this drug. We present a 45-year-old man who deliberately took 30 g of metformin, presumably with suicidal intent. He had not eaten the previous night and presented with altered sensorium and recurrent seizures. He had profound metabolic acidosis at presentation with a pH of 7.06 and a low blood sugar of 44 mgs/dl. The patient was admitted in intensive care unit (ICU) with the suspicion of metformin-associated lactic acidosis. He developed irreversible renal failure, neurological deterioration and anemia. Despite of daily intensive hemodialysis and other supportive measures the patient expired 14 days later. Metformin overdose with renal failure and severe lactic acidosis have high mortality; hence, urgent medical consultation and treatment can be life saving in these patients.

Metformin is a biguanide used in the treatment of type 2 diabetes mellitus. It lowers hepatic glucose production and peripheral insulin resistance. Hypoglycaemia is seen only after intake of toxic doses or in combination with other antidiabetic drugs or after prolonged fasting. As metformin is excreted by the kidneys, care must be taken in renal insufficiency or liver disease because of risk of lactic acidosis. Large overdoses of metformin can lead to lactic acidosis as well. Suicide with metformin is rare. Intake of 35 g of metformin has been shown to be lethal ( Teale et al. 1998 ). In the present paper we report on the treatment and outcome of a 70 year old man after ingestion of 63 g of metformin. Previously, survival after intake of up to 50 g has been described.

Treating Metformin Overdose

Treating Metformin Overdose

Metformin Overdose is a common problem and the possibility of overdose is more amongst people as this prescription medicine is consumed for treating Type II diabetes. And Diabetes these days is a common health issue. Effects of a metformin overdose varies and depends on a variety of factors, like the amount of metformin consumed or whether it was consumed with any other medicines, it was taken while one had already had alcohol, drugs etc. If you or someone you know happens to overdose on metformin, it is advised that medical attention is given to the patient immediately. The possible symptoms of Metformin overdose may be two; Lactic acidosis and Low Blood Pressure. Symptoms of each of them are given below. Symptoms of Lactic acidosis are: Muscle pain, feeling tired, week and exhausted, trouble breathing, abnormal stomach pain, dizziness, and in some cases when medical attention is not given on time or given very late Metformin Overdose may lead to loss of life also. Symptoms of low blood pressure due to Metaformin overdose are Extreme hunger, Dizziness, Sweating, Cold sweats and Shakiness, and Blurred vision. Sometimes the symptoms can be extreme like Changes in behavior, such as irritability, Loss of coordination, Difficulty speaking, Confusion, Loss of consciousness, Coma, Seizure and in the cases when the patient is not given medical attention on time it can result in death of the person who has overdosed on Metformin. On Metformin overdose patient the doctor may use certain medicines or put a tube into the stomach to “pump the stomach.” As a result of this certain other complications may occur and to deal with it the doctors may have to opt for supportive treatments. Supportive treatment of Metformin Overdose may include Dialysis, Fluids through an intravenous l Continue reading >>

Metformin Overview

Metformin Overview

Metformin is a prescription medication used to treat type 2 diabetes. Metformin belongs to a group of drugs called biguanides, which work by helping your body respond better to the insulin it makes naturally, decreasing the amount of sugar your liver makes, and decreasing the amount of sugar your intestines absorb. This medication comes in tablet, extended-release tablet, and liquid forms. It is taken up to 3 times daily, depending on which form you are taking. Swallow extended-release tablets whole. Common side effects of metformin include diarrhea, nausea, and upset stomach. Metformin is a prescription medication used to treat type 2 diabetes. This medication may be prescribed for other uses. Ask your doctor or pharmacist for more information. Metformin may be found in some form under the following brand names: Serious side effects have been reported including: Lactic Acidosis. In rare cases, metformin can cause a serious side effect called lactic acidosis. This is caused by a buildup of lactic acid in your blood. This build-up can cause serious damage. Lactic acidosis caused by metformin is rare and has occurred mostly in people whose kidneys were not working normally. Lactic acidosis has been reported in about one in 33,000 patients taking metformin over the course of a year. Although rare, if lactic acidosis does occur, it can be fatal in up to half the people who develop it. It is also important for your liver to be working normally when you take metformin. Your liver helps remove lactic acid from your blood. Make sure you tell your doctor before you use metformin if you have kidney or liver problems. You should also stop using metformin and call your doctor right away if you have signs of lactic acidosis. Lactic acidosis is a medical emergency that must be treate Continue reading >>

Metformin Overdosage

Metformin Overdosage

Metformin is a biguanide used to treat type 2 diabetes mellitus and most commonly prescribed oral hypoglycemic agent. Metformin is now also used to treat polycystic ovary syndrome and some malignancies. Despite a good safety profile in a majority of patients with diabetes, the risk of metformin-associated lactic acidosis is genuine when safety guidelines are ignored. Overdoses with metformin are rare, but may result in serious consequences. Case reports and small case series of serious toxicity from metformin overdosage can be found in the medical literature, often with the portrayal of extracorporeal methods for the management of the subsequent severe lactic acidosis. Lactic acidosis can defined as a metabolic acidosis with a blood pH less than 7.35 and a serum lactate more than 2 mmol per liter. It can occur either with therapeutic metformin dosing (which is rare) or in overdose situations. 0.03 cases of lactic acidosis per 1000 patient-years occur within therapeutic dosing, with a majority of these cases among patients that have contraindications to metformin (such as renal insufficiency). In overdose situations, lactic acidosis is seen much more habitually, even though the precise incidence is unclear. Lactic acidosis has been observed in 1.6% of metformin exposures reported to poison control centers; nevertheless, merely 10% of these exposures were due to deliberate overdoses. The incidence of metformin-associated lactic acidosis was 12.8% in a review of poison control center inquiries from Germany. The minimum reported lethal dose was found in a 42 year-old patient who had a blood metformin level of 188 µg/ml (e.g. therapeutic range level is usually between 0.5–2.5 µg/ml). Although the intake of 35 g of metformin has shown to be lethal, the maximum reported to Continue reading >>

Metformin rarely causes hypoglycaemia but it can cause a profound lactic acidosis in overdose and in patients with renal failure. Used therapeutically to inhibit glucogenogenesis and stimulate peripheral glucose uptake, in toxic doses it causes a profound lactaemia. All the mechanisms are unclear but it is in part due to the inhibition of gluconeogenesis (which lactate is required). Therefore in healthy individuals there is some build up of lactate, this is normally excreted in the urine but at impaired renal function or an acute overdose there is excess lactate. It is not metabolised and excretion relies solely on renal excretion A lactic acidosis in the context of therapeutic metformin has a high mortality rate and an underlying cause (sepsis) needs to be managed Metformin overdose is usually benign but doses > 10 grams are concerning Lactic acidosis will occur in these individuals who are susceptible (renal, cardiac, respiratory failure) or in patients who have ingested co-ingestants or are on medications that impair cardiac and renal function Severe lactic acidosis usually manifests with non-specific symptoms several hours later but can progress to coma, shock and death Children: Unintentional ingestion of up to 1700mg is benign. Hypoglycaemia, if present can be managed with dextrose . Severe acidosis and hyperkalaemia may require the administration of sodium bicarbonate (1 2 mmol/kg). However, it is likely the patient is already hyperventilating to compensate for the metabolic acidosis, haemodialysis is the ultimate priority. If in a patient on therapeutic metformin, stop further administration and seek the underlying cause for their deterioration (sepsis, acute kidney injury) Screening: 12 lead ECG, BSL, Paracetamol level 50 grams of charcoal to the co-operative Continue reading >>

Metformin Accidental Overdose

Metformin Accidental Overdose

Diabetes Forum The Global Diabetes Community Find support, ask questions and share your experiences. Join the community I have taken 2 x 500mg metformin by mistake what should I do? is it harmful? Shouldn't have too much impact. Can you take bs reading? I went too low on it once or twice as my doseage was too high. Had a hypo and ate tsp of honey which sorted it out. Do you do readings? If so, what's your normal reading? Keep an eye. A hypo is 4 or anything below. If you are worried make sure someone else around, tell them what you've done. You could ring 111. Happily it is not a very powerful drug and, in my opinion, it won't cause you problems. However if you have a meter then test and if you don't have a meter and go vague, slight headache and maybe a tremour then eat something sweet. @Scandichic suggests that if you are worried then call 111 and I think that's a good idea too. This is the dose that a lot of people on metformin take. It may give you a dodgy stomach if you are not used to that dose. Also depends what your levels are usually whether it may take you too low and you hypo. I have taken 2 x 500mg metformin by mistake what should I do? is it harmful? many thanks for those who took time to reply. 111 replied quite soon, but to actually speak to someone took much longer. it's the first time it's happened, won't be so worried next time! Glad you're ok! I got prescribed 3 but lost a substantial amount of weight. Kept feeling funny and asked doc who poo pooed it. Hubbie called 111 as kept drifting in and out of consciousness. Hospital set no met, doc said carry on. Chemist said load of crap and reduced it to 1. Now lost 4 stone and still on 1. Works well. If I stop, bs goes up a bit despite low carbing. And I am very low carb. So take 1. Hugsxxx Continue reading >>
