01 · Your filing deadline
Illinois has a 2-year statute of limitations for personal injury claims (735 ILCS 5/13-202). Illinois uses the Frye general acceptance standard for novel scientific evidence in civil cases, asking whether the scientific methodology is generally accepted in the relevant scientific community. This Frye standard — the same used in Delaware — may be more permissive for Zantac causation experts than the federal Daubert standard that resulted in the MDL dismissal. A lawyer can confirm yours.
Cook County Circuit Court is an experienced and sophisticated venue for complex litigation.
Deadlines vary; a lawyer can confirm yours. An older diagnosis or a past filing window does not, by itself, establish whether you have a claim.

02 · Where cases are heard
Illinois has a 2-year statute of limitations for personal injury claims and follows a Frye standard for novel scientific expert testimony — similar to Delaware and New York. The Frye standard in Illinois state courts may be more permissive than federal Daubert for Zantac causation experts, making Illinois a potentially favorable venue for state court filings. Chicago's Cook County court system is experienced in complex pharmaceutical mass tort litigation.
Statute of Limitations — IL (2 years): Illinois applies a 2-year limitations period for personal injury under 735 ILCS 5/13-202. The discovery rule runs from the date the plaintiff knew or reasonably should have known of the injury and its probable drug-related cause. The FDA's April 2020 nationwide recall of all ranitidine products is frequently cited as the constructive discovery date for plaintiffs who had not previously connected their diagnosis to Zantac use, though courts may look to earlier individualized facts. Plaintiffs with diagnosed cancers — particularly bladder, esophageal, stomach, colorectal, liver, pancreatic, breast, or lung — should consult counsel to preserve claims.
