The FDA recently recalled certain drugs containing valsartan
hera ‘s what patients should know, including alternatives and cancer risk
respective common drugs that contain valsartan, used to treat high blood pressure and heart failure, have been recalled in the United States due to an “ impurity ” in the drug that poses a likely cancer hazard .
That impurity, N-nitrosodimethylamine or NDMA, is classified as a probable human carcinogen, based on results from lab tests .
The medicines included in the voluntary recall are valsartan from major Pharmaceuticals, Solco Healthcare and Teva Pharmaceuticals Industries, ampere well as valsartan/hydrochlorothiazide from Solco and Teva .
The medicines that have been recalled as of October 24 are sold by Teva Pharmaceuticals labeled as major Pharmaceuticals, Prinston Pharmaceutical Inc. labeled as Solco Healthcare LLC, Teva Pharmaceuticals USA labeled as Actavis, AvKARE ( Teva/Actavis ), RemedyRepack Inc. ( Prinston/Solco ), A-S Medication Solutions LLC ( Teva/Actavis & Prinston/Solco ), Bryant Ranch Prepack Inc. ( Teva/Actavis ), H J Harkins Company Inc. dba Pharma Pac ( Prinston/Solco ), Northwind Pharmaceuticals ( Teva/Actavis ), Hetero Labs, Inc. labeled as Camber Pharmaceuticals, Inc., NuCare Pharmaceuticals Inc. ( Prinston/Solco ), RemedyRepack, Inc. ( Hetero/Camber ), AvKARE ( Hetero/Camber ), Preferred Pharmaceuticals, Inc. ( Hetero/Camber ), Torrent Pharmaceuticals Limited, and RemedyRepack, Inc. ( Torrent ) .
extra data about the specific recalled products, including doses, distribute numbers and passing dates, is detailed on the FDA ’ s web site .
Valsartan is off apparent and is used as a component of other generic medicines, but not all medicines containing the ingredient are involved in the hark back .
The US Food and Drug Administration noted in a news spill that “ the presence of NDMA was unexpected ” and thought to be related to changes in the manner the active kernel was manufactured .
“ Our drug shortages team is besides working hard to ensure patients ’ remedy needs are met in the United States with an adequate provide of insensible medications, ” FDA Commissioner Dr. Scott Gottlieb said in the statement .
The FDA military action came after 22 other countries issued recalls involving 2,300 valsartan batches sent to Germany, Norway, Finland, Sweden, Hungary, the Netherlands, Austria, Ireland, Bulgaria, Italy, Spain, Portugal, Belgium, France, Poland, Croatia, Lithuania, Greece, Canada, Bosnia and Herzegovina, Bahrain and Malta .
immediately, the US echo has left some patients who take valsartan-containing drugs scratching their heads over what to do about their treatment regimens .
“ Their biggest concern is about their hazard of cancer and better understanding how refer they should be, ” said Dr. Suzanne Steinbaum, director of women ’ s cardiovascular prevention, health and health at Mount Sinai in New York and a spokeswoman for the American Heart Association .
“ They are asking if there is any testing that should be done. Patients are now asking if they should only request ‘ brand-name ’ medicine rather of generic in order to make sure that this doesn ’ thyroxine happen. last, they all want to stop the medication, ” Steinbaum said, noting that ’ s not the correct action to take .
Experts offered four main takeaways for patients in the inflame of the recall .
Not all valsartan drugs have the ‘impurity’
In general, not all medications containing valsartan are included in the recall, because not all valsartan-containing medicines were provided the valsartan supply linked to the NDMA “ impurity. ”
Since the recall, the external supplier linked to the problem has stopped distributing its valsartan component, and the FDA has been working with the affected companies to reduce the chances of such a recall occurring in future products, according to the agency .
In the meanwhile, “ there are other medications that contain valsartan, some in combination with amlodipine, and those do not appear to be part of the remember, ” said Dr. Gregory Prokopowicz, conductor of the Johns Hopkins Hypertension Center and assistant professor of medicine at the Johns Hopkins University School of Medicine .
Amlodipine can be used alone or in combination with other medications to treat high blood blackmail and chest pain .
“ It ’ s besides crucial to know that the medicine Entresto – that ’ s made by Novartis that contains valsartan and sacubitril and is for heart failure – is not affected by the recall, ” he said. “ So patients taking that medication should not stop their medicine. ”
The recall does not affect any Novartis or Sandoz valsartan products in the United States or any Novartis Pharma products that contain valsartan, according to a affirmation from the company .
“ The valsartan API ( active pharmaceutical ingredient ) in these products does not come from the like reservoir as those products affected outside the United States, ” the argument said, as specific batches of Sandoz valsartan and Sandoz valsartan and hydrochlorothiazide film-coated tablets were recalled outside the US this calendar month .
Patients in the US taking those valsartan medications or Diovan, Diovan HCT, Exforge, Exforge HCT or Entresto should continue as directed by their physicians, the statement said.

The FDA noted that patients should look at the drug name and company name on the labels of their prescription drug bottles to determine whether their medicate has been recalled. If the information is not on the bottle, patients should call their drugstore for those details .
Valsartan alternatives are available
“ Patients taking the recalled valsartan-containing medicines should consult their doctor or pharmacist and continue taking their music until they have a successor product, ” Steinbaum said .
“ The conditions the medicine process – affection failure and high blood coerce – are dangerous, and patients could be harmed if they suddenly stop taking it without a replacement prescription, ” she said .
A health caution professional could help provide data about other valsartan-containing products or alternative discussion options .
Patients “ could switch to a different generic manufacturer. Or they could switch to another medication in the same course of drugs. The course of drugs is known as angiotensin receptor blockers, or ARBs, ” Prokopowicz said .
“ There are eight drugs on the market in that category. therefore there ’ second a count of drugs to which they could be switched, other than valsartan. Examples are losartan, irbesartan, olmesartan, and there are a number of others, ” he said. “ In addition to the ARB drugs, there are many, many other blood pressure drugs that could be easily and safely substituted for valsartan, tied outside of that category. So it varies from patient to patient. ”
Those patients who have switched to a different drug should monitor their blood pressure closely, said Dr. Erin Michos, an associate professor and associate film director of preventive cardiology at Johns Hopkins Medicine .
“ It is potential their lineage atmospheric pressure might respond differently to the newly medicine and doses might need to be adjusted under the steering of their health caution provider, ” said Michos, whose own patients have been asking her about the valsartan recall .
“ Whenever transfer or adjusting new lineage pressure medications, I recommend that patients keep a log with their blood imperativeness numbers and time of day the measurement was taken, and share this log with their health care supplier to review and make adjustments, ” she said. “ I am largely merely switching my patients off valsartan to another ARB ; that is the easiest solution. ”
What is the valsartan cancer risk?
As of nowadays, the long-run risks posed by the NDMA found in certain valsartan-containing drugs remain reasonably unknown, and the sum of NDMA consumed would play a role in those risks, Michos said .
In early words, “ the dose makes the poison, ” she said .
“ What we know about the dangers of this impurity comes chiefly from testing ground studies. It is a toxin that can affect the liver and cause liver fibrosis or scar and liver tumors in rats. So it is assumed to be toxic to humans, a well, ” Michos said .
“ In these animal studies, they normally give big quantities, so again, the risk is likely not the like equivalent in humans, ” she said .
NDMA, an organic chemical that forms in both industrial and natural processes, has been used to make melted rocket fuel, softeners and lubricants, among other products. It can besides be unintentionally produced through certain chemical reactions and is a by-product from some pesticide fabricate, the cook of condom tires or fish march .
vulnerability to high gear levels of NDMA may cause liver damage in humans, according to the US Environmental Protection Agency .
“ I decidedly am switching my patients off this medication if supplied by one of the moved companies, ” Michos said. “ I am surely refer, but I think it is excessively soon to panic. This recall is a precaution for base hit. ”
To put the recall in perspective, Dr. Howard Weintraub, a cardiologist and professor of medicine at NYU Langone Health, said that he told his patients about a meta-analysis cogitation on angiotensin receptor blockers in general and cancer risk .
That study, published in the journal Medicine in 2016, involved analyzing data from 19 randomized controlled trials including 148,334 patients .
“ Looking at all of those trials that were conducted with a kind of these medications within the ARB family, there was no hint of a cancer risk, ” said Weintraub, who was not involved in the report .
“ It was a very well-done analysis of older trials, and there was no ambiguity that there was not a signal of cancer risk, ” he said .
‘Taking medicines is not a substitute for a good lifestyle’
overall, the conversation around valsartan-containing medications is a reminder for patients to be mindful of maintaining healthy habits along with their medicine regimen, Weintraub said.
