Adequate pharmaceutical warnings; limiting civil liability for manufacturers or sellers who provide warning to a learned intermediary

(a) A manufacturer or seller of a prescription drug or medical device may not be held liable in a product liability action for a claim based upon inadequate warning or instruction unless the claimant proves, among other elements, that: (1) The manufacturer or seller of a prescription drug or medical device acted unreasonably in failing to provide reasonable instructions or warnings regarding foreseeable risks of harm to prescribing or other health care providers who are in a position to reduce the risks of harm in accordance with the instructions or warnings; and (2) Failure to provide reasonable instructions or warnings was a proximate cause of harm. (b) It is the intention of the Legislature in enacting this section to adopt and allow the development of a learned intermediary doctrine as a defense in cases based upon claims of inadequate warning or instruction for prescription drugs or medical devices.
