An appeal was made by Charles D. Hahn against Howard A. Richter, M.D., and The Upjohn Company regarding a negligence and strict liability case. The Supreme Court of Pennsylvania upheld the Superior Court's decision favoring Upjohn. Hahn had been treated for back pain from 1977 to 1980 by Dr. Richter, who administered several procedures and intrathecal injections of Depo-Medrol, a drug from Upjohn. Warnings in the drug's package insert indicated that arachnoiditis—a scarring of spinal nerves—had been reported with intrathecal use, which was not FDA-approved. Hahn developed arachnoiditis and subsequently suffered further injury during surgery to remove scar tissue.

In 1982, Hahn filed suit against Dr. Richter and Upjohn, later releasing Dr. Richter from the claim. The case against Upjohn proceeded to trial in 1989, where Hahn sought to establish that his condition was caused by Depo-Medrol and that Upjohn failed to provide adequate warnings. The jury found in favor of Upjohn. The trial court instructed the jury that they could find Upjohn liable for negligence due to inadequate warnings but did not allow for strict liability claims, citing that negligence was the sole basis for recovery in cases involving prescription drugs with warnings. The court's reliance on the Restatement (Second) of Torts § 402A was affirmed, specifically noting that comment k excludes strict liability for prescription drugs when proper warnings are provided. The court concluded that manufacturers have a duty to warn of unknown risks, as established in prior case law.

Negligence is the alleged basis for recovery in this case, with strict liability deemed inapplicable as per comments j and k of the Restatement. The standard of care follows § 388, which holds suppliers responsible for exercising reasonable care to inform users of known dangers associated with a product. The court cited Baldino v. Castagna, where a drug manufacturer was found liable for inadequate product warnings based on negligence rather than strict liability. It reinforced that a manufacturer is not strictly liable for consequences from the use of a product if adequate warnings are provided, affirming liability arises only from negligence in warning users about dangers. The trial court correctly instructed that the manufacturer could be liable for negligence in failing to provide adequate warnings, and the decision to exclude strict liability instructions was upheld by the Superior Court.

Justice Cappy dissenting argued that the majority's ruling effectively exempts all prescription drugs from strict liability for failure to warn. Cappy criticized the majority's reliance on the cases of Incollingo and Baldino, asserting that those cases centered on negligence and did not support the notion that negligence and strict liability are equivalent in this context. Cappy contended that the majority’s interpretation of comment j to § 402A was flawed and that the court had historically rejected attempts to merge negligence principles into strict liability claims.

Negligence theory is deemed irrelevant in Pennsylvania law concerning strict liability, particularly for drugs. The dissent argues against the majority's shift towards incorporating negligence principles in these cases, asserting it undermines established legal precedent and public policy that delineates responsibility for harm caused by manufactured products. The dissent emphasizes that negligence concepts should not apply to prescription drugs any more than to other products like lawn mowers or automobiles. A critical concern is the majority's failure to analyze the policy implications of its decision, particularly the balance between protecting pharmaceutical companies and compensating injured patients. The majority's ruling is seen as favoring the pharmaceutical industry without addressing the societal costs of defective drugs, effectively shifting the burden onto patients. This outcome creates a situation where patients become "unpaid guinea pigs," which the dissent finds unacceptable. The dissent concludes with a call for a more comprehensive examination of the implications of the majority's decision and expresses strong opposition to its findings. Justice Castille joins this dissent. Additionally, a note references Comment k, which acknowledges that certain products, especially drugs, cannot be made entirely safe and may carry inherent risks, justifying their use despite potential dangers.

A seller of products is not strictly liable for harm resulting from their use, provided the products are properly prepared, marketed, and accompanied by appropriate warnings when necessary. If a product contains a known risk that is deemed reasonable, the seller is not required to warn consumers about it. However, if a product includes an ingredient that poses a significant risk to a substantial portion of the population—especially if that risk is not widely recognized—the seller must provide a warning if they are aware of the ingredient or should reasonably be aware of it. This requirement extends to dangerous substances, including poisonous drugs. Conversely, sellers are not obligated to warn about dangers that arise only from excessive consumption or long-term use of substances that are commonly understood to be harmful, such as alcohol or saturated fats. When warnings are provided, sellers can assume that consumers will read and heed them, and a product with such warnings is not considered defective or unreasonably dangerous if used as directed. The legal principles outlined in comment j have been referenced in several court cases, emphasizing that a warning is unnecessary when dangers are generally known, and that a product with an adequate warning is not defective.
