Indiana Law Review Oral Contraceptives: Heading Into an Era of Unpredictability, Unlimited Liability, and Unavailability? I. Introduction Technological advances have placed modern man in a precarious position. Now, more than ever, man is capable of creating and producing materials suited to solve the problems of the world, yet these beneficial products frequently bear concomitant hazards which cannot be avoided; that is, **some products ... are quite incapable of being made safe for their intended and ordinary use.'" However, general tort principles indicate that manufacturers of such products will bear no liability if their product is properly manufactured and accompanied by adequate directions and warnings.^ Consequently, the manufacturer of any product it knows or should know is dangerous bears an unquestioned duty to warn the product's consumer of its potential hazards or adverse effects.^ Yet, as with many across-the-board rules, this common law duty to warn has its exceptions. For instance, when a manufacturer sells products that are generally used under the supervision of engineers or technicians, the manufacturer fulfills its duty to warn when it supplies adequate warnings and instructions to the supervisory engineers or technicians, rather than the actual user.'* Similarly, when a manufacturer supplies a product to members of a trade or profession, it bears no duty to warn of hazards generally known to that trade or profession.^ Nowhere have there been more exceptions to the duty to warn the user than in the area of pharmaceuticals. Beginning in the mid-1960s, courts have almost universally held that manufacturers of prescription drugs have a 'Restatement (Second) of Torts § 402A, comment k (1965). ^Id. This Restatement comment goes on to emphasize: [T]he seller of such products, again with the qualification that they are properly prepared and marketed, and proper warning is given, where the situation calls for it, is not to be held to strict liability for unfortunate consequences attending their use, merely because he has undertaken to supply the public with an apparently useful and desirable product, attended with a known but apparently reasonable risk. Id. 'See, e.g., Illinois State Trust Co. v. Walker Mfg. Co., 73 111. App. 3d 585, 589, 392 N.E.2d 70, 73 (1978); Craven v. Niagara Mach. and Tool Works, Inc., 417 N.E.2d 1165, 1169 (Ind. Ct.

However, limitations on the above-cited ex- ceptions to the common law duty to warn the consumer directly were forewarned in the Restatement (Second) of Torts section 388, comment n, which states: Giving to the third person through whom the [product] is supplied all the information necessary to its safe use is not in all cases sufficient to relieve the supplier from liability .... The question remains whether this method gives reasonable assurance that the information will reach those whose safety depends on their having it '« / "See Canterbury v. Spence, 464 F.2d 772, 780 (D.C. Cir.), cert, denied, 409 U.S. 1064 (1972), where the court first cited Schloendorff v. Society of New York Hospital, 211 N.Y. 125, 129-30, 105 N.E. 92, 93 (1914), overruled in Bing v. Thunig, 2 N.Y.2d 656, 143 N.E.2d 3 (1957), for the proposition: '* 'Every human being of adult years and sound mind has a right to determine what shall be done with his own body ....'" A/. The Canterbury court interpreted "informed consent" in the following way: True consent to what happens to one's self is the informed exercise of a choice, and that entails an opportunity to evaluate knowledgeably the options available and the risks attendant upon each. The average patient has little or no under- standing of the medical arts, and ordinarily has only his physician to whom he can look for enlightenment with which to reach an intelligent decision. From these almost axiomatic considerations springs the need, and in turn the require- ment, of a reasonable divulgence by physician to patient to make such a decision possible.

Where the danger involved in the ignorant use of their true quality is great and such means of disclosure are practicable and not unduly burdensome, it may well be that the supplier should be required to adopt them.

Ortho Pharmaceutical Corporation^'' and two similar cases,'* the manufacturer of oral contraceptives was held liable for its failure adequately to warn the consumer directly in spite of its compliance with FDA packaging/labeling requirements.'^ These cases present a puz- zling question as to how manufacturers are to satisfy their duty to warn the consumer directly in the case of oral contraceptives distributed nationwide in light of the fact that each court held that the adequacy of any given warning must be determined against state negligence law as interpreted by a jury. Yet, because sucTi adequacy standards are never concretely fashioned prior to user injury and have the potential to vary from state to state, oral contraceptive manufacturers held to these stand- ards embark upon an era of certain unpredictability and probable un- limited liability. In addition, an analysis of the reasoning used in these "In this context, "inadequate way" describes the situation in which a manufacturer's warnings to the physician about a product's potential adverse effects were not, in turn, passed on to the patient in an understandable manner by the physician after an individualized assessment of the risks and benefits.

This Note will initially trace the development of the doctrine of the learned intermediary and the limitations on this doctrine as they first appeared in the area of vaccines. In addition, it will briefly discuss the emergence of the oral contraceptive industry and the public's call for FDA intervention in the labeling of its products. Next, this Note will consider the application of the learned intermediary doctrine in early oral contraceptive cases and its apparent inapplicability in three recent oral contraceptive cases — McDonald, Odgers, and Stephens. Finally, the Note will explore the potential effects of these latest holdings on the manufacturers of oral contraceptives and the expansion of the MacDonald holding to other prescription drugs. II. The Emergence of the Learned Intermediary Doctrine and Its Early Limitation: The Vaccine Cases Today it is well established that a prescription drug manufacturer discharges its duty to warn of its product's risks and hazards when it supplies physicians with adequate information about the drug's associated side effects.^^ This general tort principle, now commonly referred to as the doctrine of the learned intermediary, was originally conceived in the case of Love v. Wolf.^^ In Love, the California Court of Appeals held that the manufacturer of chloromycitin, an antibiotic used in the treatment of minor ailments, had no specific duty to warn the patient directly.^^ Instead, the man- ufacturer's common law duty to warn could be discharged through '''See Reyes, 498 F.2d 1264, 1276 (5th Cir.) cert, denied, 419 U.S. 1096 (1974), where a prescription drug manufacturer's duty to warn was explained as follows: [W]here prescription drugs are concerned, the manufacturer's duty to warn is limited to an obligation to advise the prescribing physician of any potential dangers that may result from the drug's use .... Prescription drugs are likely to be complex medicines, esoteric in formula and varied in effect. As a medical expert, the prescribing physician can take into account the propensities of his patient. His is the task of weighing the benefits of any medication against its potential dangers. The choice he makes is an informed one, an individualized medical judgment bottomed on a knowledge of both patient and palliative. Id. (emphasis in original). See also Mauldin v. Upjohn Co., 697 F.2d 644, 647 (5th Cir.), cert, denied, 464 U.S. 848 (1983) (manufacturer of antibiotics not required to warn patient directly if physician adequately warned); Dyer v. Best Pharmaceutical, 118 Ariz. 465, 468, 577 P.2d 1084, 1087 (1978) (manufacturer of pharmaceutical used for anorexiant purposes was under duty to warn the physician only); McKee v.

Rptr. 183 (1964). "/^. at 395, 38 Cal. Rptr. at 193. 1986] ORAL CONTRACEPTIVES 619 adequate warning given to either the physician or the patient.^^ Implicit in the Love decision was the court's reluctance to impose a direct duty to warn the patient-consumer on manufacturers, which normally have only minimal contact with the ultimate users of the drugs. ^'^ This mere reluctance of the Love court planted the seed that ultimately grew into the learned intermediary doctrine. The term "learned intermediary'* was first coined in Sterling Drugs, Inc. v. Cornish,^^ when it was applied descriptively to denote the special liaison-like role the physician plays between patient and drug manufacturer. In Cornish, the primary issue on review for the Eighth Circuit Court of Appeals was whether the defendant-drug manufacturer had a duty to warn the prescribing physician of recently-discovered side effects of its product, Aralen, an anti-arthritic agent. Affirming the judgment below in favor of a plaintiff who suffered chloroquine retinopathy, a degenerative disease of the eye resulting from ingesting Aralen, the Eighth Circuit Court of Appeals emphatically held that the drug manufacturer did have a duty to warn the physician, a measure which, in the court's opinion, would minimize the number of patients injured by adverse effects.^^ Although the court's discussion of the learned intermediary doctrine was limited to one paragraph, this single phrase became authority for subsequent judicial rulings that a drug manufacturer has a duty to warn only the physician.^^ From this relatively unnoticed beginning, the doctrine of the learned intermediary emerged as a general tort principle that has been given credence either directly or indirectly in nearly every case in which a plaintiff brought a warning-related action against a prescription drug manufacturer.^* Although this doctrine has been summarized in almost "/
