Are you using an SGLT2 Inhibitor drug and experiencing serious side effects? If so, you may have grounds for a personal injury claim. Other patients are reporting serious issues after using these drugs.
Type 2 sodium-glucose co-transporter (SGLT2) inhibitors are newer drugs used to treat Type 2 diabetes.
Two of these drugs are also available in combination form with another antidiabetic medication, metformin.
About Type 2 Diabetes
Diabetes is a medical condition in which the body does not process sugar correctly. Over time, excessive glucose levels in the bloodstream may damage organs. The damaged organs may include the eyes, kidneys, and skin. These are resulting in blindness, kidney failure, and the necessity for amputation of the feet and legs.
Type 2 diabetes is the most common and affects up to 28 million Americans. It is often related to obesity and may contribute to a number of additional disease including hypertension, high cholesterol levels and cardiovascular death.
In normal people, insulin helps to transport glucose or sugar from the bloodstream into the cells, where it can be used as energy. Type 2 diabetics may not produce enough insulin, or the blood cells may have become resistant to insulin – leaving much of the sugar in the bloodstream.
Antidiabetic medication has traditionally worked by increasing the production of insulin. These drugs assist with increasing the body’s sensitivity to insulin or by preventing insulin from being absorbed in the intestines.
As newer medications, SGLT2 inhibitors antidiabetics work differently from other antidiabetic medications. Those patients who struggled with other medications were given these instead, but many are suffering serious SGLT2 side effects and filing lawsuits.
SLGT2 Inhibitor Actions
When the kidneys work normally in a non-diabetic patients, extra glucose in the bloodstream filters from the blood and is reabsorbed back into the bloodstream by the kidney “tubules” where it can be used as energy.
As type 2 diabetics have too much glucose in the blood, SGLT2 inhibitors prevent the kidneys from reabsorbing that glucose so that it is passed out of the body in the urine. SGLT2 inhibitors result in over 100 grams of sugar being excreted into the urine. This is the same as excreting over 400 calories, causing some people to lose weight.
All medications have side effects, most of which are mild to moderate. The SGLT2 inhibitors have a number of serious side effects that can even be life-threatening.
Common side effects of SGLT2 inhibitors include:
- Yeast infections including vaginal, vulvar and penile (banal) infections
- Urinary tract infection including bladder and kidney infections
- Intolerance to the sun
- Rash and itching, often from yeast infection on skin
- Fatigue or loss of energy
More severe side effects of SGLT2 inhibitors may warrant emergency medical action.
Diabetic ketoacidosis is caused by high levels of ketones in the bloodstream which are produced by the body when it is unable to use glucose in the cells. The ketones are a byproduct of fat metabolism and are acidic in nature. The disorder can quickly deteriorate and become life-threatening.
Symptoms of diabetic ketoacidosis or ketosis may include:
- Increased thirst and urination
- Excessive hunger
- Abdominal pain or nausea
- Fatigue, Weakness, Dizziness
- Shortness of breath, Sweating, Rapid heart beat
- “Fruity” odor to the breath
If the patient does not receive treatment, the following symptoms may occur:
- Confusion or extreme irritability
- Dizziness or Fainting
- Trouble breathing
If left untreated, diabetic ketoacidosis is life-threatening.
Unfortunately, many Type 2 diabetics will not recognize the symptoms and the original prescribing information and patient instructions did not list diabetic ketoacidosis as a concern.
Other Serious Side Effects
In addition, the medical data company, IMS has identified hundreds of additional serious adverse events that occurred in patients who took the newer SGLT2 inhibitor antidiabetic medications. The newer diabetic medications may also cause:
- Low blood pressure
- Changes in laboratory blood levels of potassium, cholesterol, hemoglobin and others
- Decreased kidney function
- Allergic reactions
Data shared in early 2017 by the European Medicines Agency found a high risk of toe amputation for those individuals using SGLT2 inhibitors.
In January, 2017, research was published in Diabetes Care showing that patients taking SGLT2 inhibitors may suffer the risk of renal injury.
Some medical professionals, including several FDA advisory committee members have expressed concern about an increased risk of heart attack and companies have been ordered to complete additional safety studies of the effects on the heart, bones, and liver and to look into the risk of cancer and pregnancy risk.
Public Citizen has also objected to advertising regarding the SGLT2 medications stating that “reduced blood pressure” as claimed by the medication’s marketing material is not a benefit, but a potentially harmful side effect as described in the literature.
They have also objected to the non-approved claim that “some” patients may lose weight on these medications as the notification often appears close to the approved indications which the group feels may be confusing and cause some to believe the medication is approved for use as a weight loss agent. Public Citizen has all three medications on its “Do Not Use” list on its website.
FDA Reactions to SGLT2 Inhibitor Side Effects and Risks in 2015 and Beyond
In May 2015, the FDA issued a warning letter regarding the risk of diabetic ketoacidosis, citing 20 serious adverse events reports the agency had received. Prescribing information for the medications has listed a “contraindication” (reason against use) for patients with DKA but literature contains no clear warning about the risk.
