Metformin is a drug that is used to treat diabetes.


Metformin is a medication used to treat type 2 diabetes.

Patients with type 2 diabetes use the drug metformin to lower their blood sugar levels. It works by lowering the quantity of blood sugar produced by the liver. It also aids in improving the body’s insulin response.

The diabetic medication, which belongs to the biguanide family of medications, is said to be made from natural chemicals found in French lilac. In traditional medicine, these natural substances were believed to be used to cure “sweetwater illness.” Fortamet, Glucophage, Glucophage XR, Glumetza, and Riomet are some of the brand names for metformin medicine.

Metformin may be used alone or in combination with other medications to help manage blood sugar levels. The metformin tablet should be taken exactly as prescribed by your doctor. Diabetes medicine is just one component of a comprehensive treatment plan that may include include diet, exercise, and frequent blood sugar testing.

The American Association of Clinical Endocrine and the American College of Endocrinology refer to the drug as a lifestyle treatment option for those with type 2 diabetes.

Despite the fact that metformin has some negative side effects, the benefits usually exceed the risks for individuals with type 2 diabetes. The following are some of the possible metformin side effects:


  • Lactic acidosis is a condition in which the body produces too much lactate
  • Diarrhea
  • Nausea
  • Vomiting
  • Flatulence
  • stomach ache
  • Weakness
  • The mouth has a metallic flavor to it.

Metformin is a drug that is used to treat polycystic ovarian syndrome in women as well as type 2 diabetes. Metformin has been shown to enhance fertility in certain people. Women who are planning a pregnancy should talk to their doctor about birth control alternatives while taking metformin.

Concerns about the Metformin Recall


Is Metformin Linked to Cancer?

N-Nitrosodimethylamine (NDMA), a molecule that may develop as a manufacturing byproduct, has allegedly been found in some batches of the metformin diabetic medication.

NDMA was formerly used to manufacture rocket fuel. It’s been labeled as a possible human carcinogen.

Despite the fact that there have been no instances of metformin causing cancer, the FDA has ordered the affected diabetic medications to be recalled owing to NDMA contamination.

Only the extended-release versions of the diabetic medication were allegedly contaminated with NDMA. According to the FDA, no contamination issues have been discovered in metformin immediate-release formulations.

There have been no reports of malignancy linked to the tainted metformin batches so far. Long-term exposure to NDMA, on the other hand, may raise the risk of different cancers.

Patients should continue taking metformin until their doctor can prescribe a substitute prescription, according to the FDA.

The possibility of bladder cancer linked with diabetes has been a source of worry. Certain diabetic medicines, such as Takeda Pharmaceuticals’ Actos, have been linked to an increased risk of bladder cancer. Patients using metformin for diabetes did not have a lower risk of bladder cancer, according to a research published in the journal Diabetes Care.

Why Did the FDA Issue a Recall for Metformin?

The US Food and Medication Administration reported on May 28, 2020, that some batches of the diabetic drug metformin had tested positive for dangerous amounts of N-Nitrosodimethylamine (NDMA), a chemical related to cancer. As a manufacturing byproduct, the chemical can develop. It is a kind of environmental pollutant found in water, meats, dairy products, and vegetables.

The FDA ordered five medication companies to recall their metformin products because they had NDMA levels over the 96ng/day Acceptable Daily Intake Limit (ADI). Only specific extended-release variants of metformin are affected by the recall.

As a result, four pharma companies have agreed to a voluntary metformin recall for the concerned batches of the diabetic medication.

After the FDA informed Amneal Pharmaceuticals that testing revealed excessive amounts of NDMA in seven lots of Metformin Hydrochloride Extended Release Tablets, USP, 500 mg and 750 mg, the company voluntarily recalled all lots of the medicine on May 29, 2020.

The manufacturer claims that no significant metformin side effects have been reported as a result of the recall. Further scientific assessments of the diabetic medication are also being conducted, according to the firm.

Apotex Corp. voluntarily recalled all supplies of its extended-release metformin medicine after the FDA discovered contamination in one batch, according to an official statement from the manufacturer. According to Apotex, metformin was discontinued in the United States in February 2019, and there is now very little of the diabetic medication on the market in the United States. Metformin Hydrochloride Extended-Release Tablets, USP, 500mg are included in the Apotex recall.

The Actavis and Time-Caps Labs Inc. brands of metformin medicine have also been recalled.

The following items are included in the metformin recall:

  • Metformin Hydrochloride Extended-Release Tablets, USP 500mg and 750mg Actavis Metformin Hydrochloride Extended-Release Tablets, USP 500mg and 750mg Actavis Metformin Hydrochloride (NDC numbers 62037-571-01, 62037-571-10, 62037-577-01, and 62037-571-10)
  • USP 500mg and 750mg Amneal Metformin Hydrochloride Extended-Release Tablets (NDC numbers 53746-178-01, 53746-178-05, 53746-178-10, 53746-178-90, 53746-178-Bulk, 65162-178-09, 65162-178-10, 65162-178-11, and 65162-178-50 in the 500 mg dosages and NDC numbers of 53746-179-01, 53746-179-Bulk, and 65162-179-10 in the 750 mg dosages)
  • Metformin Hydrochloride Extended-Release Tablets, USP 500mg, Apotex Corp. (NDC number 60505-0260-1)
  • Metformin Hydrochloride Extended-Release Tablets, USP 500mg (Lot # XP9004), Time-Caps Labs Inc.

All of the medication companies state that they have not received any reports of metformin side effects. The fifth metformin manufacturer to be recalled by the FDA has yet to be identified.

Metformin isn’t the only medication that’s been tainted by NDMA. NDMA poisoning resulted in the recall of many popular cardiac medicines last year.

Have any Metformin cautionary statements been issued?

On May 28, the FDA issued a metformin warning and recall request due to a possible cancer risk in some batches of the diabetic medication metformin. The businesses impacted by the FDA’s request for a metformin recall have said that they would inform their distributors and consumers who are affected by the recall.

If you have a prescription for metformin, you should get medical advice from your physician.

Until then, the FDA advises that you continue to take the medication as prescribed since stopping it without the advice of a medical expert may be hazardous. If you’re not sure if your prescription medication is impacted by the metformin recall, you may ask your pharmacist.

Have there been any Metformin Cancer Lawsuits filed?

As of yet, no metformin cancer lawsuits have been filed. However, the drugmakers are expected to face further metformin lawsuits alleging that they failed to guarantee the safety of their medicines, putting patients at an elevated risk of cancer.

Potential litigants may claim that if they had realized that metformin could cause cancer owing to NDMA contamination, they would have selected a different diabetic medication.

Whether or not metformin users have been diagnosed with cancer, a metformin lawsuit may seek compensation for the price of the drug, past and future medical expenditures, costs of medical monitoring, lost earnings, pain and suffering, and other damages.

Metformin is a diabetes drug that has been in use for over 40 years. The manufacturer of the drug is under investigation for amputating limbs of patients who had developed complications with the drug. Reference: metformin lawsuit amputation.
