Dr P Pillans,former Medical Assessor, Centre for Adverse Reactions Monitoring (CARM), Dunedin Metformin is a useful anti-hyperglycaemic agent but significant mortality is associated with drug-induced lactic acidosis. Significant renal and hepatic disease, alcoholism and conditions associated with hypoxia (eg. cardiac and pulmonary disease, surgery) are contraindications to the use of metformin. Other risk factors for metformin-induced lactic acidosis are sepsis, dehydration, high dosages and increasing age. Metformin remains a major reported cause of drug-associated mortality in New Zealand. Of the 12 cases of lactic acidosis associated with metformin reported to CARM since 1977, 2 occurred in the last year and 8 cases had a fatal outcome. Metformin useful but small risk of potentially fatal lactic acidosis Metformin is a useful therapeutic agent for obese non-insulin dependent diabetics and those whose glycaemia cannot be controlled by sulphonylurea monotherapy. Lactic acidosis is an uncommon but potentially fatal adverse effect. The reported frequency of lactic acidosis is 0.06 per 1000 patient-years, mostly in patients with predisposing factors.1 Examples of metformin-induced lactic acidosis cases reported to CARM include: A 69-year-old man, with renal and cardiac disease, was prescribed metformin due to failing glycaemic control on glibenclamide monotherapy. He was well for six weeks, then developed lactic acidosis and died within 3 days. Post-surgical lactic acidosis caused the death of a 70-year-old man whose metformin was not withdrawn at the time of surgery. A 56-year-old woman, with no predisposing disease, died from lactic acidosis following major Continue reading >>

A Side Effect You Should Know About

A Side Effect You Should Know About

The glucose-lowering medication metformin (Glucophage) could cause lactic acidosis if your kidneys and liver are not working efficiently. Lactic acidosis is when high levels build up in the blood of a substance called lactic acid — a chemical that is normally produced by your body in small amounts and removed by your liver and kidneys. The risk of lactic acidosis goes up if you: have heart failure or a lung ailment have kidney or liver problems drink alcohol heavily In these cases, you might not be able to take metformin. If you don't have one of these problems, you are at a very low risk for developing lactic acidosis from metformin. You should, however, contact your doctor immediately if you suddenly develop any of these symptoms of lactic acidosis: diarrhea fast and shallow breathing muscle pain or cramping weakness tiredness or unusual sleepiness You should also let your doctor know if you get the flu or any illness that results in severe vomiting, diarrhea, and/or fever, or if your intake of fluids becomes significantly reduced. Severe dehydration can affect your kidney or liver function and increase your risk of lactic acidosis from metformin. Continue reading >>

Metformin-induced Lactic Acidosis: No One Left Behind

Metformin-induced Lactic Acidosis: No One Left Behind

Abstract Metformin is a safe drug when correctly used in properly selected patients. In real life, however, associated lactic acidosis has been repeatedly, although rarely, reported. The term metformin-induced lactic acidosis refers to cases that cannot be explained by any major risk factor other than drug accumulation, usually due to renal failure. Treatment consists of vital function support and drug removal, mainly achieved by renal replacement therapy. Despite dramatic clinical presentation, the prognosis of metformin-induced lactic acidosis is usually surprisingly good. In the previous issue of Critical Care, Friesecke and colleagues demonstrate that the survival rate of patients with severe lactic acidosis due to metformin accumulation can be strikingly higher than expected based on the initial clinical evaluation [1]. Metformin is nowadays the first-line drug of choice for the treatment of adults with type 2 diabetes [2]. This drug is the sixth most frequently prescribed in the USA (> 50 million prescriptions in 2009) and is taken by almost 1.5% of the Italian population [3, 4]. Metformin is a safe drug when correctly used in properly selected patients. In particular, no cases of lactic acidosis (a relatively common side effect of other biguanide compounds) were reported in 347 trials with 70,490 patient-years of metformin use [5]. Real life can differ from research settings, however, and lactic acidosis has been repeatedly, although rarely, observed in patients treated with metformin. The number of inquiries to the Swedish Poison Information Centre for metformin intoxication has increased 10 times during the past decade, with 25 cases of severe lactic acidosis reported in 2007 and 2008 [6]. According to the American Association of Poison Control Centers, metform Continue reading >>

JANUMET tablets contain 2 prescription medicines: sitagliptin (JANUVIA®) and metformin. Once-daily prescription JANUMET XR tablets contain sitagliptin (the medicine in JANUVIA®) and extended-release metformin. JANUMET or JANUMET XR can be used along with diet and exercise to lower blood sugar in adults with type 2 diabetes. JANUMET or JANUMET XR should not be used in patients with type 1 diabetes or with diabetic ketoacidosis (increased ketones in the blood or urine). If you have had pancreatitis (inflammation of the pancreas), it is not known if you have a higher chance of getting it while taking JANUMET or JANUMET XR. Metformin, one of the medicines in JANUMET and JANUMET XR, can cause a rare but serious side effect called lactic acidosis (a buildup of lactic acid in the blood), which can cause death. Lactic acidosis is a medical emergency that must be treated in a hospital. Call your doctor right away if you get any of the following symptoms, which could be signs of lactic acidosis: feel cold in your hands or feet; feel dizzy or lightheaded; have a slow or irregular heartbeat; feel very weak or tired; have unusual (not normal) muscle pain; have trouble breathing; feel sleepy or drowsy; have stomach pains, nausea, or vomiting. Most people who have had lactic acidosis with metformin have other things that, combined with the metformin, led to the lactic acidosis. Tell your doctor if you have any of the following, because you have a higher chance of getting lactic acidosis with JANUMET or JANUMET XR if you: have severe kidney problems or your kidneys are affected by certain x-ray tests that use injectable dye; have liver problems; drink alcohol very often, or drink a lot of alcohol in short-term “binge” drinking; get dehydrated (lose large amounts of body fluids, w Continue reading >>

how can we change anti retro viral drugs for a patient who has developed lactic acidosis while on AZT/3TC,NVP? Lactic acidosis is a condition caused by the buildup of lactic acid in the body. It leads to acidification of the blood (acidosis), and is considered a distinct form of metabolic acidosis. The cells produce lactic acid when they use glucose for energy in the absence of adequate oxygen. If too much lactic acid stays in the body, the balance tips and the person begins to feel ill. The signs of lactic acidosis are deep and rapid breathing, vomiting, and abdominal pain; similar symptoms for diabetic ketoacidosis (DKA). Lactic acidosis may be caused by diabetic ketoacidosis or liver or kidney disease, as well as some forms of medication, most notably metformin also sold as "Glucophage," which is often prescribed for persons with type 2 diabetes, insulin resistance, and women for polycystic ovarian syndrome (PCOS). The Cohen-Woods classification (1976) categorises causes of lactic acidosis as follows: Type A: Decreased perfusion or oxygenation Type B:B1: Underlying diseases (sometimes causing type A) B2: Medication (including metformin [Glucophage]) or intoxication B3: Inborn error of metabolism, including diabetes usually type 1, but also type 2. Metabolic acidosis is a state in which the blood pH is low (under 7.35) due to increased production of H+ by the body or the inability of the body to form bicarbonate (HCO3-) in the kidney. Its causes are diverse, and its consequences can be serious, including coma and death. Together with respiratory acidosis, it is one of the two general types of acidosis.

Lactic Acidosis

Lactic Acidosis

Lactic acidosis is a medical condition characterized by the buildup of lactate (especially L-lactate) in the body, which results in an excessively low pH in the bloodstream. It is a form of metabolic acidosis, in which excessive acid accumulates due to a problem with the body's metabolism of lactic acid. Lactic acidosis is typically the result of an underlying acute or chronic medical condition, medication, or poisoning. The symptoms are generally attributable to these underlying causes, but may include nausea, vomiting, rapid deep breathing, and generalised weakness. The diagnosis is made on biochemical analysis of blood (often initially on arterial blood gas samples), and once confirmed, generally prompts an investigation to establish the underlying cause to treat the acidosis. In some situations, hemofiltration (purification of the blood) is temporarily required. In rare chronic forms of lactic acidosis caused by mitochondrial disease, a specific diet or dichloroacetate may be used. The prognosis of lactic acidosis depends largely on the underlying cause; in some situations (such as severe infections), it indicates an increased risk of death. Classification[edit] The Cohen-Woods classification categorizes causes of lactic acidosis as:[1] Type A: Decreased tissue oxygenation (e.g., from decreased blood flow) Type B B1: Underlying diseases (sometimes causing type A) B2: Medication or intoxication B3: Inborn error of metabolism Signs and symptoms[edit] Lactic acidosis is commonly found in people who are unwell, such as those with severe heart and/or lung disease, a severe infection with sepsis, the systemic inflammatory response syndrome due to another cause, severe physical trauma, or severe depletion of body fluids.[2] Symptoms in humans include all those of typical m Continue reading >>

Lactic Acidosis

Lactic Acidosis

The buildup of lactic acid in the bloodstream. This medical emergency most commonly results from oxygen deprivation in the body’s tissues, impaired liver function, respiratory failure, or cardiovascular disease. It can also be caused by a class of oral diabetes drugs called biguanides, which includes metformin (brand name Glucophage). Another biguanide called phenformin was pulled from the market in the United States in 1977 because of an unacceptably high rate of lactic acidosis associated with its use. Concerns about lactic acidosis also delayed the introduction of metformin to the U.S. market until 1995, despite the fact that it had been widely used for years in other countries. There have been reports of lactic acidosis occurring in people taking metformin, and the U.S. Food and Drug Administration estimates that lactic acidosis occurs in 5 out of every 100,000 people who use metformin for any length of time. However, this risk is much lower than it was in people taking phenformin, and it is not clear whether the episodes of lactic acidosis associated with metformin have actually been due to metformin use. In fact, the lactic acidosis could have been explained by the person’s diabetes and related medical conditions. Nonetheless, diabetes experts recommend that metformin not be used in people with congestive heart failure, kidney disease, or liver disease. They also recommend that it be discontinued (at least temporarily) in people undergoing certain medical imaging tests called contrast studies. Symptoms of lactic acidosis include feeling very weak or tired or having unusual muscle pain or unusual stomach discomfort. Continue reading >>

Lactic Acidosis: Symptoms, Causes, And Treatment

Lactic Acidosis: Symptoms, Causes, And Treatment

Lactic Acidosis: Symptoms, Causes, and Treatment Lactic acidosis is a physiological condition that occurs due to an increase of lactic acid in the blood. This causes the blood pH to become too acidic. To know more about its symptoms, causes, and treatment, read on... Lactate is a by-product formed when glucose is broken down aerobically by the cell's mitochondria - the power house of the cell. When the body or a region of the body is deprived of oxygen, it leads to tissue hypoxia. This results in anaerobic breakdown of the glucose in the cells. The end product of this reaction is lactic acid. The blood pH becomes too acidic due to presence of excess lactic acid in the tissues. Thus, leading to lactic acidosis, a rare condition. People who suffer from this condition may develop serious complications, especially when they suffer from certain risk factors. In extreme cases, it may also lead to death. The body generates most of its energy aerobically, that is, by using oxygen. Under normal circumstances, the cells break down glucose by a process called glycolysis, to generate pyruvate, which is further broken down by an aerobic pathway for more energy. However, under certain conditions, like trying to outrun a hungry lion or pumping iron to increase triceps and biceps, our body requires more energy. The requirement of energy becomes inversely proportional to the body's capacity to deliver the required amount of oxygen. Thus, pyruvate is converted to lactate, which allows glucose production and energy is produced. Within one or two minutes the lactic acid level increases in the blood. Thus, leading to this condition that occurs due to buildup of lactic acid in the muscles and blood. Most of the time after a strenuous exercise, running or due to some other activity, one may Continue reading >>

Review Metformin-associated Lactic Acidosis: Current Perspectives On Causes And Risk

Review Metformin-associated Lactic Acidosis: Current Perspectives On Causes And Risk

Abstract Although metformin has become a drug of choice for the treatment of type 2 diabetes mellitus, some patients may not receive it owing to the risk of lactic acidosis. Metformin, along with other drugs in the biguanide class, increases plasma lactate levels in a plasma concentration-dependent manner by inhibiting mitochondrial respiration predominantly in the liver. Elevated plasma metformin concentrations (as occur in individuals with renal impairment) and a secondary event or condition that further disrupts lactate production or clearance (e.g., cirrhosis, sepsis, or hypoperfusion), are typically necessary to cause metformin-associated lactic acidosis (MALA). As these secondary events may be unpredictable and the mortality rate for MALA approaches 50%, metformin has been contraindicated in moderate and severe renal impairment since its FDA approval in patients with normal renal function or mild renal insufficiency to minimize the potential for toxic metformin levels and MALA. However, the reported incidence of lactic acidosis in clinical practice has proved to be very low (< 10 cases per 100,000 patient-years). Several groups have suggested that current renal function cutoffs for metformin are too conservative, thus depriving a substantial number of type 2 diabetes patients from the potential benefit of metformin therapy. On the other hand, the success of metformin as the first-line diabetes therapy may be a direct consequence of conservative labeling, the absence of which could have led to excess patient risk and eventual withdrawal from the market, as happened with earlier biguanide therapies. An investigational delayed-release metformin currently under development could potentially provide a treatment option for patients with renal impairment pending the resu Continue reading >>

Lactic Acidosis | The Well Project

Lactic Acidosis | The Well Project

Mitochondria are small organs inside your cells. They help convert energy in the food you eat into energy your body uses to function. Like solar cells that convert sunlight into electricity, mitochondria are power plants inside your cells that convert glucose (sugar) into usable energy. At the same time, lactic acid is made as a waste product. Normally, the body breaks down lactic acid and gets rid of it. Certain HIV drugs in the nucleoside reverse transcriptase inhibitor (NRTI) class sometimes have negative side effects that may lead to liver problems. One such side effect is damage to the mitochondria inside your cells, or mitochondrial toxicity. When mitochondria are damaged, lactic acid is not broken down. This can cause levels of lactic acid in your blood to rise. If the levels of lactic acid become too high, a rare, but serious condition called lactic acidosis can occur. Lactic acidosis can develop when your cells make too much lactic acid or when your liver is not working properly to get rid of it. Certain HIV drugs in the NRTI class can sometimes cause these problems: Cells make too much lactic acid: NRTIs can damage the mitochondria, causing them to be unable to break down the lactic acid they produce as they make energy. This is also known as mitochondrial toxicity. The liver is not working properly: NRTIs can cause the liver to become fatty. A fatty liver does not work well and cannot break down lactic acid efficiently. Lactic acidosis is a rare side effect of the NRTIs, especially Zerit (stavudine, d4T) and Videx (diadanosine, ddI). Persistent nausea, vomiting, and abdominal (belly) pain Enlarged or tender liver (area just under the right ribcage) It is important to get in touch with your health care provider right away if you experience these symptoms.

Metformin

Metformin

A popular oral drug for treating Type 2 diabetes. Metformin (brand name Glucophage, Glucophage XR, Glumetza, Riomet) is a member of a class of drugs called biguanides that helps lower blood glucose levels by improving the way the body handles insulin — namely, by preventing the liver from making excess glucose and by making muscle and fat cells more sensitive to available insulin. Metformin not only lowers blood glucose levels, which in the long term reduces the risk of diabetic complications, but it also lowers blood cholesterol and triglyceride levels and does not cause weight gain the way insulin and some other oral blood-glucose-lowering drugs do. Overweight, high cholesterol, and high triglyceride levels all increase the risk of developing heart disease, the leading cause of death in people with Type 2 diabetes. Another advantage of metformin is that it does not cause hypoglycemia (low blood glucose) when it is the only diabetes medicine taken. Metformin is typically taken two to three times a day, with meals. The extended-release formula (Glucophage XR) is taken once a day, with the evening meal. The most common side effects of metformin are nausea and diarrhea, which usually go away over time. A more serious side effect is a rare but potentially fatal condition called lactic acidosis, in which dangerously high levels of lactic acid build up in the bloodstream. Lactic acidosis is most likely to occur in people with kidney disease, liver disease, or congestive heart failure, or in those who drink alcohol regularly. (If you have more than four alcoholic drinks a week, metformin may not be the best medicine for you.) Unfortunately, many doctors ignore these contraindications (conditions that make a particular treatment inadvisable) and prescribe metformin to people Continue reading >>

Lactic Acidosis: Symptoms, Causes, And Treatment

Lactic Acidosis: Symptoms, Causes, And Treatment

Lactic acidosis occurs when the body produces too much lactic acid and cannot metabolize it quickly enough. The condition can be a medical emergency. The onset of lactic acidosis might be rapid and occur within minutes or hours, or gradual, happening over a period of days. The best way to treat lactic acidosis is to find out what has caused it. Untreated lactic acidosis can result in severe and life-threatening complications. In some instances, these can escalate rapidly. It is not necessarily a medical emergency when caused by over-exercising. The prognosis for lactic acidosis will depend on its underlying cause. A blood test is used to diagnose the condition. Lactic acidosis symptoms that may indicate a medical emergency include a rapid heart rate and disorientaiton. Typically, symptoms of lactic acidosis do not stand out as distinct on their own but can be indicative of a variety of health issues. However, some symptoms known to occur in lactic acidosis indicate a medical emergency. Lactic acidosis can occur in people whose kidneys are unable to get rid of excess acid. Even when not related to just a kidney condition, some people's bodies make too much lactic acid and are unable to balance it out. Diabetes increases the risk of developing lactic acidosis. Lactic acidosis may develop in people with type 1 and 2 diabetes mellitus , especially if their diabetes is not well controlled. There have been reports of lactic acidosis in people who take metformin, which is a standard non-insulin medication for treating type 2 diabetes mellitus. However, the incidence is low, with equal to or less than 10 cases per 100,000 patient-years of using the drug, according to a 2014 report in the journal Metabolism. The incidence of lactic acidosis is higher in people with diabetes who Continue reading >>

Glyburide And Metformin (oral Route)

Precautions Drug information provided by: Micromedex It is very important that your doctor check your progress at regular visits to make sure this medicine is working properly. Blood tests may be needed to check for unwanted effects. Under certain conditions, too much metformin can cause lactic acidosis. The symptoms of lactic acidosis are severe and quick to appear. They usually occur when other health problems not related to the medicine are present and very severe, such as a heart attack or kidney failure. The symptoms of lactic acidosis include abdominal or stomach discomfort; decreased appetite; diarrhea; fast, shallow breathing; a general feeling of discomfort; muscle pain or cramping; and unusual sleepiness, tiredness, or weakness. If you have any symptoms of lactic acidosis, get emergency medical help right away. It is very important to carefully follow any instructions from your health care team about: Alcohol—Drinking alcohol may cause severe low blood sugar. Discuss this with your health care team. Other medicines—Do not take other medicines unless they have been discussed with your doctor. This especially includes nonprescription medicines such as aspirin, and medicines for appetite control, asthma, colds, cough, hay fever, or sinus problems. Counseling—Other family members need to learn how to prevent side effects or help with side effects if they occur. Also, patients with diabetes may need special counseling about diabetes medicine dosing changes that might occur because of lifestyle changes, such as changes in exercise and diet. Furthermore, counseling on contraception and pregnancy may be needed because of the problems that can occur in patients with diabetes during pregnancy. Travel—Keep your recent prescription and your medical history with yo Continue reading >>

Lactic Acidosis: What You Need To Know

Lactic Acidosis: What You Need To Know

Lactic acidosis is a form of metabolic acidosis that begins in the kidneys. People with lactic acidosis have kidneys that are unable to remove excess acid from their body. If lactic acid builds up in the body more quickly than it can be removed, acidity levels in bodily fluids — such as blood — spike. This buildup of acid causes an imbalance in the body’s pH level, which should always be slightly alkaline instead of acidic. There are a few different types of acidosis. Lactic acid buildup occurs when there’s not enough oxygen in the muscles to break down glucose and glycogen. This is called anaerobic metabolism. There are two types of lactic acid: L-lactate and D-lactate. Most forms of lactic acidosis are caused by too much L-lactate. Lactic acidosis has many causes and can often be treated. But if left untreated, it may be life-threatening. The symptoms of lactic acidosis are typical of many health issues. If you experience any of these symptoms, you should contact your doctor immediately. Your doctor can help determine the root cause. Several symptoms of lactic acidosis represent a medical emergency: fruity-smelling breath (a possible indication of a serious complication of diabetes, called ketoacidosis) confusion jaundice (yellowing of the skin or the whites of the eyes) trouble breathing or shallow, rapid breathing If you know or suspect that you have lactic acidosis and have any of these symptoms, call 911 or go to an emergency room right away. Other lactic acidosis symptoms include: exhaustion or extreme fatigue muscle cramps or pain body weakness overall feelings of physical discomfort abdominal pain or discomfort diarrhea decrease in appetite headache rapid heart rate Lactic acidosis has a wide range of underlying causes, including carbon monoxide poisoni Continue reading >>

D-lactic Acidosis: A Personal Experience

D-lactic Acidosis: A Personal Experience

We began the roller coaster ride called short bowel syndrome (SBS) in 2007. When my daughter Ally was four years old, she lost all but twenty-five centimeters of her small intestine due to a mid-gut volvulus. Her colon remained intact. Early on I joined various social media sites, as well as the Oley Foundation. Thankfully, I read of others experiences where their child acted drunk due to D-lactic acidosis, so when Ally first had symptoms I was aware of this disorder. We didnt begin having significant D-lactic issues until 2013. Ally had had a colostomy reversed and we later found out that she had nerve damage resulting in poor colonic motility. It was the perfect storm for D-lactic acidosis: very short small intestine, high amounts of enteral carbs to keep her off parenteral nutrition (PN), and poor colonic motility. Her symptoms have ranged from mildly blurred vision to a comatose-like sleep state. Specifically, over the years Ally has experienced slurred speech, incoherent speech, inability to walk, out-of-character anger or silliness, deep sleep that goes on for hours to days, academic decline, and hall All during one of her sleepy episodes of D-Lactic ucinations. She was exceptionally good at coloring, but in a D-lactic episode she would scribble and would think it was beautiful. At the worst of her D-lactic episodes, she could not remember the six to eight hours a day that she had spent in an episode. At best she would be a little cranky and maybe take a long nap. We say shes either a happy drunk, an angry drunk, or a sleepy drunk. We went about six months with Ally having D-lactic episodes about four to five times per week and without successful treatment. The usual antibiotics did not help. While the effects would go away and there were no lingering neurologica Continue reading >>
