Who may be affected
The Suboxone lawsuits are brought by people who say they used Suboxone (buprenorphine / naloxone) and were later diagnosed with one or more of the alleged injuries above. Whether any individual situation could support a claim depends on the specific facts, the medical records, and each state's filing deadline (statute of limitations) — which can expire, so timing matters.
