To Date, More Attention Paid To The Association Between These Sodium Glucose Cotransporter 2 Inhibitors And Diabetic Ketoacidosis Or Acute Kidney Injury (Posted by Tom Lamb at The FDA has mandated drug label changes for Invokana, Farxiga, and Jardiance, as well as Invokamet, Xigduo, Glyxambi, and Synjardy, as regards some serious side effects and is currently investigating various others. To date, most attention has been directed to the association between these Sodium Glucose Cotransporter 2 (SGLT2) Inhibitors and diabetic ketoacidosis. For example, see this December 2015 article, "FDA Adds Ketoacidosis Warnings To Diabetes Drugs Invokana, Farxiga, And Jardiance As Well As Other SGLT2 Inhibitors". More recently, there was an FDA announcement concerning a label change about the acute kidney injury side effect, as covered in this June 2016 article, "Invokana, Invokamet, Farxiga, Xigduo: Warnings About Acute Kidney Injury Risk Are Increased On Revised Drug Labels For These Diabetes Medicines". What has received less attention, it seems, is the fact that these still relatively new diabetes drugs -- Invokana, Farxiga, and Jardiance, as well as their several "combination" products -- have been linked to serious urinary tract infections (UTIs) that can result in more severe conditions, such as urosepsis and...

According To Drug Regulators, New Possible Side Effects Include: Fatal Cases Of Ketoacidosis; Leg, Foot, And Toe Amputations; And, Lactic Acidosis (Posted by Tom Lamb at On June 14, 2016 the FDA announced it has strengthened the existing warning about the risk of acute kidney injury for Invokana and Invokamet as well as Farxiga and Xigduo XR. These relatively new diabetes drugs are known as Sodium-Glucose Co-Transporter-2 (SGLT2) Inhibitors. Notably missing from this June 2016 drug safety warning were Jardiance (empagliflozin), Glyxambi (empagliflozin and linagliptin), and Synjardy (empagliflozin and metformin hydrochloride), which are also part of the SGLT2 Inhibitors class of drugs. About a month later, however, only those three diabetes drugs from Boehringer Ingelheim Pharmaceuticals, Inc. received a Supplemental Approval letter from the FDA concerning a label change about ketoacidosis, an apparent serious side effect. Using the July 8, 2016 FDA letter for Jardiance as a representative document showing this most recent revision to the safety information for these drugs: Please refer to your Supplemental New Drug Application (sNDA) dated and received February 12, 2016.... This Prior Approval supplemental new drug application proposes to amend the Jardiance Prescribing Information and Patient Information with new text informing that fatal... Continue reading

Melanoma Skin Cancer: FDA Is Evaluating The Need For Regulatory Action; More Lawsuits Filed; Another Research Study (Posted by Tom Lamb at In late June 2016 the Food and Drug Administration (FDA) said it will study a potential link between melanoma skin cancer and erectile dysfunction (ED) drugs such as Viagra, Cialis, and Levitra. This announcement appeared in the agency's latest watch list of drugs with possible safety issues, "January - March 2016: Potential Signals of Serious Risks/New Safety Information Identified from the FDA Adverse Event Reporting System (FAERS)". In relevant part, the document listed these drugs which have been associated with melanoma as a serious side effect. PDE-5 inhibitors: Adcirca (tadalafil; Eli Lilly and Company): tablets Cialis (tadalafil; Eli Lilly and Company): tablets Levitra (vardenafil hydrochloride; GlaxoSmithKline): orally disintegrating tablets Revatio (sildenafil citrate; Pfizer): tablets, oral suspension, and injection Staxyn (vardenafil hydrochloride; GlaxoSmithKline): orally disintegrating tablets Stendra (avanafil; Vivus and Auxilium Pharmaceuticals): tablets Viagra (sildenafil citrate; Pfizer): tablets From this July 1, 2016 Medscape article, "New FDA Watch List: Possible ED Drug–Melanoma Link and More", we get some background information about that June 2016 FDA investigation announcement: The agency will be on the heels of other researchers when...

Some Xarelto And Eliquis Lawsuits Accuse Drug Makers Of Failing To Warn That In Event Of Uncontrollable Bleeding There Is No Antidote, Just Like With Savaysa (Posted by Tom Lamb at The headline of a recent medical news report about Savaysa (edoxaban), from Daiichi Sankyo, made it seem that there are no serious problems with the use of this still relatively new non-vitamin K antagonist oral anticoagulant. Published June 20, 2016 by Healio - HemOnc Today, "Edoxaban safe, effective for extended prevention of recurrent VTE" starts out with this apparent ringing endorsement: Extended treatment with the oral anticoagulant [Savaysa (edoxaban)] prevented recurrent venous thromboembolism and led to fewer major bleeding events than warfarin among patients with venous thromboembolism, according to a post-hoc analysis of a randomized trial. For what it is worth, I want to point out that Daiichi Sankyo funded this study. But more interesting, I think, is how this Healio - HemOnc Today news reports ends, focusing on the continuing lack of any FDA-approve antidote for Savaysa, as well as Eliquis and Xarelto. The growing availability of agents for the reversal of bleeding caused by direct oral anticoagulants suggests that they can be used regularly and safely,... Continue reading

Meanwhile Jardiance, Glyxambi, And Synjardy, Also In The SGLT2 Inhibitors Class Of Diabetes Drugs, May Help Slow Progression Of Kidney Disease In Patients At High Cardiovascular Risk (Posted by Tom Lamb at In May 2016 this drug safety labeling change for Invokana (canagliflozin) was approved By FDA Center for Drug Evaluation and Research (CDER): WARNINGS AND PRECAUTIONS Acute Kidney Injury and Impairment in Renal Function INVOKANA causes intravascular volume contraction and can cause renal impairment. There have been postmarketing reports of acute kidney injury, some requiring hospitalization and dialysis, in patients receiving INVOKANA; some reports involved patients younger than 65 years of age. Then on June 14, 2016 the FDA announced it has strengthened the existing warning about the risk of acute kidney injury for Invokana and Invokamet as well as Farxiga and Xigduo XR. Based on recent reports, the side effects warnings in the drug labels have been revised to include more exact information about acute kidney injury. More precisely, from the Data Summary part of this document, "FDA Drug Safety Communication: FDA strengthens kidney warnings for diabetes medicines canagliflozin (Invokana, Invokamet) and dapagliflozin (Farxiga, Xigduo XR)", we get this detailed information: A search of the FDA Adverse...

Drug Company Announces It Will Recall Zecuity Skin Patches From Pharmacies As Well As Temporarily Suspend Sales, Marketing, And Distribution Of Product (Posted by Tom Lamb at On June 10, 2016 Teva Pharmaceuticals sent a so-called "Dear Doctor" letter to health care providers about Zecuity, its migraine drug patch. From this PDF document we get the following: Dear Health Care Provider: The purpose of this letter is to inform you that we are suspending the sale, marketing and distribution of ZECUITY® (sumatriptan iontophoretic transdermal system), indicated for the acute treatment of migraine with or without aura in adults. Teva has received postmarketing reports of application site reactions described as “burn” and/or “scar” in patients treated with ZECUITY. Descriptions of these reactions have included severe redness, cracked skin, blistering or welts, and burns or scars where the patch was worn. Patients described severe pain, itching, or burning. Although many cases resolved within hours to weeks, there are reports of cases with unresolved skin reactions, typically skin discoloration, after several months. On a different front, at Teva's web page, we get this information: Teva Pharmaceuticals has voluntarily suspended sales, marketing and distribution of ZECUITY (sumatriptan iontophoretic transdermal system). Teva has... Continue reading

Researchers Suggest Pharmaceutical Companies And FDA Should Reconsider OTC Availability Due To Inappropriate Use Of Nexium As Well As Prilosec and Prevacid (Posted by Tom Lamb at A team of medical researchers recently examined the so-called "mechanism of injury" for the long-term use of Nexium -- and perhaps other heartburn or reflux medications in the proton pump inhibitor (PPI) class of drugs -- apparently causing an increased risk of kidney problems as well as heart attacks and dementia. As background, there is a growing body of medical evidence which indicates that some popular heartburn drugs and acid reflux medicines like Prevacid, Prilosec, and Nexium can cause some serious kidney-related side effects. In more detail, the use of these proton pump inhibitors (PPIs) for even just a couple of weeks can result in an increased risk of developing: Acute Interstitial Nephritis (AIN) Chronic Kidney Disease (CKD) End-Stage Renal Disease (ESRD) Severe Renal Impairment Kidney / Renal Failure Acute Kidney Injury Further, there is at least one medical study which shows the correlation between a longer time period of Prevacid, Prilosec, and Nexium use, and an increased risk of developing these serious kidney or renal conditions. As for this recent medical... Continue reading

Animal Studies Have Lyrica Possibly Linked To Skeletal Malformations, Neural Tube Defects, And Other Abnormalities, But Safety Data On Lyrica Use During Human Pregnancy Are Scarce (Posted by Tom Lamb at Women who took Lyrica (pregabalin) while pregnant were about three times more likely to have babies with major birth defects compared with women who did not take Lyrica, according to study done by a team of medical researchers in Europe that was recently reported in the journal Neurology. From the Abstract for this report, "Pregnancy outcome following maternal exposure to pregabalin may call for concern", from the website ("Published online before print May 18, 2016") we get an overview of the new Lyrica research: Objective: To investigate pregnancy outcomes following maternal use of [Lyrica (pregabalin)]. Methods: This multicenter, observational prospective cohort study compared pregnancy outcomes in women exposed to [Lyrica (pregabalin)] with those of matched controls (not exposed to any medications known to be teratogenic or to any antiepileptic drugs).... Conclusions: This study demonstrated a signal for increased risk of major birth defects after first trimester exposure to [Lyrica (pregabalin)]. However, several limitations such as the small sample size, differences across groups in maternal conditions, and concomitant... Continue reading

About 4,400 Cases Still Pending In Federal Court MDL As Well As New Jersey And California State Courts (Posted by Tom Lamb at In their corporate report Form 10-Q for the first quarter of 2016, Merck & Co., Inc. provided investors and others with their most recent update about what has been going on (or has not been, as it might seem to be the situation) with the thousands of Fosamax - femur fracture cases filed against the drug company. At pages 17-18 of this Merck corporate report for the quarterly period ended March 31, 2016 (a 45-page PDF document), which was released on or about May 5, 2016, we get this information: As previously disclosed, Merck is a defendant in product liability lawsuits in the United States involving Fosamax (Fosamax Litigation)....

Biogen Idec First Added Information About Tecfidera Being Assoicated With PML Brain Infection Back In December 2014, After An FDA Drug Safety Communication Was Issued (Posted by Tom Lamb at Tecfidera is a drug used to treat relapsing forms of multiple sclerosis (MS). There is a February 29, 2016 FDA letter to Biogen Idec about a revision to the prescribing information for Tecfidera (dimethyl fumarate) having to do with progressive multifocal leukoencephalopathy (PML). But that FDA letter does not inform one further about the new drug safety information for Tecfidera concerning progressive multifocal leukoencephalopathy (PML). To see what is new, one must read Section 5.2 of the current version of the Tecfidera label (Revised: 2/2016), where an added paragraph suggests two developments. The first is that there seems to have been more Tecfidera - PML cases reported in the past year or so. And the second is that lymphonpenia possibly induced by Tecfidera might have a role to play in those additional PML cases. Here is the added paragraph, short but significant, it seems: [Progressive multifocal leukoencephalopathy (PML)] has also occurred in the postmarketing setting in the presence of lymphopenia (<0.8x109/L) persisting for more than 6 months. While the... Continue reading

PPI-Induced Acute Interstitial Nephritis Is A Kidney-Related Side Effect That Has Been Known About For Many Years, But FDA Only Mandated A Drug Label Change In December 2014 (Posted by Tom Lamb at The drug companies responsible for the following proton pump inhibitors (PPIs) heartburn drugs added to the Warning and Precautions part of their respective drug labels a new section about acute interstitial nephritis (AIN) in December 2014: Aciphex (rabeprazole sodium) Delayed-Release Tablets Dexilant (dexlansoprazole) delayed-release capsules Nexium (esomeprazole magnesium) delayed-release capsules, for oral use Nexium I.V. (esomeprazole sodium) for injection Prevacid (lansoprazole) delayed release capsules Prevacid SoluTab (lansoprazole) Delayed-Release Orally Disintegrating Tablets Protonix (pantoprazole sodium) delayed-release tablets Protonix IV (pantoprazole sodium) But there was a medical journal article about the possible increased risk of acute interstitial nephritis among users of Prilosec (omeprazole) -- the first PPI heartburn drug approved by the FDA, in 1989 -- way back in 1992. And over the past ten years, at least, as seen in some articles which are presented below, it became clear that acute interstitial nephritis was a so-called "class effect" for all of these eight proton pump inhibitors. Yet this "new" drug safety warning about PPI-induced acute interstitial nephritis... Continue reading
