In 2015, the Canadian Medical Association Journal published a study linking proton pump inhibitors to acute kidney injury. But there had been case reports of kidney injury occurring as early as 2004.

This proposed class action alleges that developers and manufacturers (including Apotex and AstraZeneca) knew their drugs could cause kidney and renal failure.

In fact, our lawsuit alleges that they actively concealed evidence of the dangers from the government and the public.

These serious side-effects can lead to lifelong complications and even death.


In 2017, proposed Canadian class actions were commenced in Saskatchewan and Ontario.

DECEMBER 2021 UPDATE: The class proceeding before the Ontario Court has not advanced and was dismissed and discontinued as of December 31, 2021. Please read this IMPORTANT NOTICE and COURT ORDER from the Ontario Superior Court for more information. This dismissal order has no effect on the class proceeding before the Saskatchewan Court, which is still being pursued.



Which drugs are included in this proposed class action?

The drugs are known by several names listed above, including Nexium, Prevacid, and Losec. They are sold both over-the-counter and as a prescription drug. These proton pump inhibitors are meant to curb heartburn and soothe GERD by reducing the amount of acid in the stomach, but long-term use can be dangerous.


Potential signs of kidney damage

Look for the following symptoms:

  • You're not urinating very much.
  • Your legs, ankles, and feet are swelling from fluid retention.
  • You have an unexplained shortness of breath.
  • You suffer from persistent fatigue.
  • You suffer from persistent nausea.
  • You feel pain or pressure in your chest.

If you have any of these symptoms, see a doctor right away. Kidney damage can lead to seizures, comas, or be life-threatening.
