In many cases, an injured claimant will bring a dangerous drug lawsuit against the manufacturer. If a production company cut corners while designing a drug or testing its effectiveness, a jury may hold them responsible for any subsequent harm.
It is also possible to file suit against the testing laboratory that was responsible for a medication’s drug trial. If the laboratory made a mistake and should have recognized that a drug was dangerous, they may bear some fault for any injuries caused by their product.
You could also bring a claim against a doctor or pharmacist.
