Converging lines of evidence support the notion that terminal hyperkalemia may explain our findings. More often than not, health professionals relied upon memory to try to avoid such complications. Its a good post about another antibiotic to avoid and I appreciate the warning. Why Don't We Listen to Women When They Are Sick? "If there's a problem with a drug interaction, it's only going to be exacerbated in a population of older adults with heart problems," he said. Overcast "One of the consequences of a high potassium level is getting these irregular heart rhythms that can be quite dangerous and cause sudden deaths," Antoniou said. Bactrim, a combination of two antibiotics, trimethoprim and sulfamethoxazole, was first approved in 1968 and 1973 in Canada and the US, respectively and has become a mainstay in pharmaceutical medicine. Sadly, there is not adequate awareness about the deadly consequences of this drug interaction. No one wants to pay much for this kind of preventive care, so you essentially donate your time and energy to do this. I developed lesions on my tongue (blood gorged papules) and peeling skin on my genitals. Ciprofloxacin (a known cause of QT interval prolongation) was also associated with an increased risk of sudden death (adjusted odds ratio 1.29, 1.03 to 1.62), but no such risk was observed with nitrofurantoin or norfloxacin. The authors have noted in previous work that cotrimoxazole combined with ACE/ARB drugs associated with a sevenfold increase in the risk of hospital admission for elevated potassium levels. Youll laugh, learn and maybe sing along. Each of the two drugs that make up Bactrim block microbial folate synthesis precipitating complete folate deprivation in bacteria, capable of resulting in folate deficiency non-bacterial cells. Chandler Marrs MS, MA, PhD spent the last dozen years in womens health research with a focus on steroid neuroendocrinology and mental health. Compared with amoxicillin, trimethoprim- sulfamethoxazole was associated with a more than twofold increase in the risk of sudden Of the 11,968 patients who died of sudden death while receiving spironolactone, we identified 328 whose death occurred within 14 days after antibiotic exposure. Ciprofloxacin (adjusted OR 1.55, 95% CI 1.02-2.38) and nitrofurantoin (adjusted OR 1.70, 95% CI 1.03-2.79) were also associated with an increased risk of sudden death, although the risk with nitrofurantoin was not apparent in a sensitivity analysis. ACE inhibitors and ARBs are used a lot. This additive adverse effect would also be expected with any other drug known to cause hyperkalaemia, such as other potassium-sparing diuretics and angiotensin-converting enzyme inhibitors, they say. In other words, an awful lot of people are vulnerable to this potentially deadly drug combination. Young healthy patients have organ reserve. A hyperkalemic crisis can come on so suddenly that even if a conscientious doctor were monitoring serum potassium levels every few months that might not be frequently enough to catch a problem in time. An interaction between the commonly prescribed antibiotic co-trimoxazole and blood pressure drugs such as lisinopril or valsartan can cause sudden death. MeSH / HealthDay. Importantly, bacterial synthesis of folate and other B vitamins, represents a critical pathway not only for nutrient availability of the human host, but for managing the vast microbial ecosystems in a manner favorable to host survival. CMAJ 2015; doi: 10.1503/cmaj.140816. While it is impossible to rule out the Keflex in his sudden illnesses, as this drug too carries potentially serious side effects, or the combination of the two drugs, I would like to focus on Bactrim for this post, and specifically, its anti-folate and anti-thiamine properties. IMS Institute for Healthcare Informatics. However, this applies equally to all the antibiotics we studied. BMJ. National prescription audit. Ciprofloxacin and nitrofurantoin were also associated with an increased risk of death (adjusted OR 1.55, 95% CI 1.02-2.38; and adjusted OR 1.70, 95% CI 1.03-2.79, respectively), although the risk with nitrofurantoin was not apparent in a sensitivity analysis. Likewise, how many of the 50 million patients treated with cotrimoxazole had a viral, not bacterial, infection? Co-trimoxazole induced hyperkalemia is common,13 18 can occur quickly,13 19 and can be life-threatening.20 We examined whether treatment with co-trimoxazole was associated with a higher risk of sudden death than other antibiotics used for urinary tract infection in patients receiving angiotensin converting enzyme inhibitors or angiotensin receptor blockers. Federal government websites often end in .gov or .mil. After just a few days on Bactrim I started experiencing rapid heart rate, hyperventilation-type symptoms, numbness and insomnia. The .gov means its official. However, with this new study, we wanted to bring awareness about a drug interaction which causes dangerously high potassium levels that some physicians and pharmacists may not be aware of, he says. We will strive to make that page accessible. But the trimethoprim not the sulfamethoxazole can also elevate potassium levels and cause an interaction, he says. 1999 Jul-Aug;45(4):209-12. doi: 10.1159/000022089. Why was its actions on folate metabolism not considered problematic? The other seemed even less concerned. There is a growing movement to identify pediatric and young adult athletes who may be at risk for sudden cardiac arrest (SCA) or sudden cardiac death (SCD) during sports participation. Parker Waichman was there for my family when one of our family members was desperately in need of assistance. We used standardized differences to compare baseline characteristics of cases and controls. Of the 1,601,542 patients in the study treated with either anACE-inhibitoror ARB, 39,879died suddenly. How can it hurt?. Gerontology. The otherness of potential drug targets holds true to this day. Insofar as thiamine is only stored in the body for about 18 days, it must be consumed regularly to avoid insufficiency and outright deficiency. For each case, we randomly selected up to four controls from the same cohort, matched on age (within 1 year), sex, and the presence or absence of kidney disease and diabetes, recognized risk factors for hyperkalemia and sudden death.29 30 Each control could serve as a control only once, although they were eligible to become a case at a later date. This is an important question, because sudden death due to hyperkalemia in the pre-hospital setting is likely to be misattributed to intrinsic heart disease, particularly in older patients with existing cardiovascular disease or diabetes.17. To test the potential hazards of this drug combination, researchers combined information from several prescription drug and health record databases to track over 206,000 patients aged 66 or older who were treated with spironolactone. MF drafted the manuscript, which was critically revised for important intellectual content by all authors. The researchers could not determine if there is a causal relationship between the antibiotic and sudden death, but they hypothesize that it may be due to the drugs ability to raise potassium levels. Thank you so much for this article. These drugs, which act via the kidney, can increase potassium levels in up to 10% of patients. February 2, 2015 / 3:49 PM I came to it from your tweet. Bicycle, Scooter, and Electric Bike Accidents, Cerebral Palsy Malpractice Injury Lawsuits, Stevens Johnson Syndrome (SJS) Disease Injury Lawyers, Clergy Sexual Abuse Lawyers | Priest Abuse Attorneys, Pennsylvania Sexual Abuse Lawsuit Lawyers, Sudden Death in Those Taking Bactrim Along with ACE Inhibitors or ARBs, Bicycle, Scooter, and Electric Bike Accident, Stevens Johnson Syndrome (SJS) Disease Injury. To the extent that thiamine is connected to the synthesis of downstream metabolites like folate synthesis, it is not unexpected either, that a background insufficiency in both nutrients would be exacerbated and potentially become deadly with the addition of Bactrim to the mix. I think that most people, doctors and patients alike, think that all antibiotics are as benign as amoxicillin. These side effects may go away during treatment as your body . Some of the most common names are: These drugs are also included in many combination products. It should be noted that the stability of the enzymes from the animal and the human liver cells varied significantly from 25-60%, calling into question the very results upon which this medication was eventually developed and approved. World Health Organization. Before Bookshelf Taken together, however, the combination yields potent bactericidal effects. Unauthorized use of these marks is strictly prohibited. 1, 1994, and Dec. 31, 2011. In the 1970s there were no computers for physicians or pharmacists to use to check for dangerous interactions and there were few references available to check out a possible problem. The importance of our findings is underscored by the fact that co-trimoxazole is prescribed to millions of patients taking angiotensin converting enzyme inhibitors or angiotensin receptor blockers. Although we had no information on indications for antibiotic use, we used a disease risk index to adjust for potential predictors of sudden death. These efforts are ongoing. Furthermore, it was deemed safe by its apparent inability to block folate in human cells. So, what do we do with this information? Compared with amoxicillin, trimethoprim-sulfamethoxazole was associated with a more than twofold increase in the risk of sudden death (adjusted OR 2.46, 95% confidence interval [CI] 1.55-3.90). All rights reserved. We speculate that this association reflects sudden death from co-trimoxazole induced hyperkalemia in a vulnerable group of patients. A few years back, I had a confirmed UTI (P. mirabilis). With the exception of co-trimoxazole, none of these is an independent risk factor for severe hyperkalemia. More recent research has found that people with poor kidney function are particularly likely to suffer from this interaction (Internal Medicine, March 1, 2016). When trimethoprim was present, folate to DFT was not reduced, even when extra folic acid was added to the media. And the researchers did not know why the individuals had been prescribed the antibiotics.But the results point toward greater caution in prescribing Bactrim to those taking ACE-inhibitors and ARBs, and closer monitoring of potassium levels in those patients. Trimethoprim is given to kill bacteria but it also acts like amiloride, (a potassium-sparing diuretic) in the kidney. On average, there have been between 6-7 million prescriptions of this drug written annually from 2007-2017, except for in 2015, where almost 12 million prescriptions were written. This first on the list shows an association between sudden death in those who were given trimethoprim-sulfamethoxazole (co-trimoxazole) while already on renin-angiotensin system blockers (i.e. Co-trimoxazole and sudden death in patients receiving inhibitors of renin-angiotensin system: population based study. In contrast, we observed no increased risk of sudden death with the other antibiotics (table 3). 27299 Riverview Center Boulevard, Suite 108. Instead of putting this in the Avoid or Caution category, it merely listed this interaction as one that should be monitored because of a possible risk of hyperkalemia. Like many human infections, UTIs are usually caused . Years later I was giving Cipro.With Cipro I had Ulnar nerve entrapment and muscle atrophy. Moreover, absent nutrient repletion post antibiotic usage, it is entirely likely that the mitochondrial ill-effects imposed by this drug would become longstanding. Each case was matched with up to four controls on age, sex, presence of kidney disease, and diabetes. Im typically somewhat deficient already due to hyperthyroidism and wondered why the sudden increase in symptoms. When trimethoprim was originally discovered and yet still, medicine believed that bacteria were somehow entirely separate from the organism in which they resided. This was by design, as blocking bacterial folate metabolism makes for a potent antibacterial, which also just so happens, makes it a viable chemotherapeutic. The answer to that question has to do in part to shoddy research and in part to an economically self-serving framework for understanding human physiology that has since become institutionalized into medical dogma. We determined the odds ratio (OR) for the association between sudden death and exposure to each antibiotic relative to amoxicillin, adjusted for predictors of sudden death using a disease risk index.
