Product Liability - Unavoidable Dangers

Although manufacturers and sellers have a duty to take precautions and provide adequate warnings and instructions, the public can still obtain products that are unavoidably unsafe. A seller is not held strictly liable for providing the public with a product that is needed and wanted in spite of the potential risk of danger. Prescription drugs illustrate this principle because all of them have the potential to cause serious harm if used unreasonably.

The duty to warn consumers of unavoidable dangers presents special problems if certain individuals are likely to suffer allergic reactions. The law considers an allergy to be a reaction suffered by a minority of people that is triggered by exposure to some substance. Courts used to reject claims based on allergic reactions, reasoning that the product was reasonably safe and that the injury was caused by a defect peculiar to the individual. That approach has been abandoned, with manufacturers providing careful instructions on use and clear warnings about possible symptoms that suggest an allergic reaction.
