Frequently asked questions

What is the Invokamet lawsuit about?

Invokamet, a combination of canagliflozin and metformin used to treat Type 2 diabetes, has been the subject of litigation alleging the manufacturer failed to adequately warn patients and physicians about serious risks including diabetic ketoacidosis (DKA), lower-limb amputations, and kidney injuries. Plaintiffs allege that Janssen Pharmaceuticals knew or should have known about these dangers before the drug reached the market. Many cases were consolidated in federal multidistrict litigation (MDL) in New Jersey.

What injuries are linked to Invokamet?

Patients have reported diabetic ketoacidosis (DKA)—a life-threatening condition where the blood becomes dangerously acidic—as well as lower-limb amputations, urinary tract infections, genital yeast infections, and acute kidney injury. The FDA issued a black-box warning for amputation risk associated with canagliflozin-containing drugs, including Invokamet, in 2017. If you or a family member suffered any of these conditions while taking Invokamet, a product liability attorney can evaluate whether you have a viable claim.

How long do I have to file an Invokamet lawsuit in New York?

In New York, personal injury claims—including pharmaceutical product liability cases—are generally governed by the three-year statute of limitations under CPLR §214. The clock typically starts when you were injured or, under the discovery rule, when you knew or reasonably should have known that your injury was caused by Invokamet. Because tolling and discovery-rule arguments are fact-specific, you should consult a NY attorney as soon as possible to avoid losing your right to sue.

What compensation can Invokamet lawsuit plaintiffs seek in NY?

Eligible plaintiffs may seek compensation for medical expenses (past and future), lost wages and earning capacity, pain and suffering, and, in cases involving gross negligence or reckless conduct, potentially punitive damages. New York does not cap compensatory damages in most personal injury cases, so the value of a claim depends heavily on the severity of the injury, documented financial losses, and the strength of the causation evidence. No outcome is guaranteed, and results vary case by case.
