The current situation is confused
In the US, the current legal requirement for a generic medicine is that the label should be identical to that of the brand-name originator. This prevents abuses by claims of efficacy for different conditions and lowers costs, but at the same time absolves generics manufacturers from all responsibility to make side effects known to their customers.

As predicted, after the recent ruling, dozens of failure-to-warn cases against generics drug manufacturers have been dismissed. What legal recourse should be open to patients who may be harmed by a generic drug? The subject was discussed in a recent article [1]. The authors point out that the choice of whether patients receive a brand-name or generic version of a particular medicinal product may be entirely out of their control.

Liability issues surrounding generic drugs have been a point of controversy in the US since the emergence of the generic drug industry in the 1960s. Pharmacists, not manufacturers, were the first to fear liability claims, in cases of injury from a medicine that was selected not by a physician but by the dispensing druggist, when substitution by generics became possible.

Should manufacturers take responsibility?
In the early days the liability risk gave the manufacturers an incentive to ensure that the warnings on their labels remained up to date. However, the Hatch-Waxman Act changed things: the application process linked generics’ claims of efficacy, safety and harm to those in the label of the brand-name drug. As a result, the original manufacturer became the steward of the public warnings for a growing family of bioequivalent drugs. This means that the brand-name drugmaker is responsible for updating the label based, in some cases, on data generated by generic drugs.
