While most drugs are accompanied by side effects and adverse reactions to varying degrees, most side effects are subtle, or obvious only to the patient. However, in the case of Reglan (metoclopramide), which is used to treat Gastroesophageal Reflux Disease (GERD), heartburn and acid reflux disease, the potential for tardive dyskinesia can contribute much hardship to a Reglan patient's life. Tardive dyskinesia is a condition characterized by involuntary movements of eyes, the mouth and jaw, the tongue, facial muscles and even limbs triggered by an adverse reaction to medication.
For anyone who operates heavy or intricate machinery, works in the retail sector or toils in any industry that involves meeting the public, such an affliction can be a career-killer and can lead to financial hardship.
The legal issue has surfaced in tandem with the inclusion of generic versions of Reglan, and what liability generic manufacturers have relative to labeling. Reuters reported December 10 that the nation's highest court will consider whether federal law preempts lawsuits brought under state law alleging inadequate labeling, given that the original drug was approved by a federal regulator, the US Food and Drug Administration.
And is a lawsuit against a generic manufacturer of Reglan, a Reglan lawsuit? It's been a thorny issue. Generic manufacturers duplicate the original drug's formulation once the patent on the original expires. In the same fashion, the warning label is also duplicated from the original. When plaintiffs have sued manufacturers of generic drugs over inadequate labeling for side effects, defendants have argued that they should escape liability because they are simply copying a label already mandated by the FDA, and thus the liability lay with the originating manufacturer.
The Supreme Court ruled in 2009, in another case, that FDA drug regulations do not protect pharmaceutical companies from being sued under state law over drug labeling.

In another case, Gladys Mensing sued three generic drug makers in federal court in Minnesota after allegedly developing a severe neurological movement disorder (Reglan tardive dyskinesia) after taking generic versions of Reglan. A US appeals court ruled her lawsuit could go forward.
Reuters reports that Supreme Court Justices will hear arguments in March or April of next year from generic manufacturers Teva Pharmaceutical Industries Ltd, Mylan Inc's UDL Laboratories and Actavis Inc. The foregoing all produce generic versions of Reglan. A decision is expected in June.
