This is an appeal in a diversity case from an $80,000.00 remitted judgment on a $110,000.00 jury award to a fifty year old Kansas citizen for permanent injury to her eyes caused by drug manufacturer’s failure to warn her doctors of a prescribed drug’s side effect.
Appellant’s grounds for appeal are as follows:
I. Refusal of the trial court to direct a verdict for appellant because there was insufficient evidence to support a verdict for the appellee.
II. Alleged errors in the court’s instructions to the jury and refusal to give certain of appellant’s requested instruсtions.
III. Refusal of the trial court to direct a verdict for appellant because the action was barred by the applicable statute of limitations, or, in the alternative, to submit to the jury the question of when the cause of action accruеd for purposes of the statute of limitations.
We affirm.
I.
Chloroquine phosphate, the drug in question, is manufactured and sold by appellant drug company under the trade name Aralen. There is no question here of any defect in the manufacture of the drug, nor of its beneficial qualities when taken as prescribed. The drug has been used widely and effectively in the treatment of arthritis. Unfortunately, the drug produces a very serious side effect in a small percentage of those to whom it is administered. The side effect is a condition known as chloroquine retinopathy, a degeneration or destruction of certain cells in the retina of eye caused
In reviewing conclusions reached by the jury, we must view the evidence in the light most favorable to the prevailing party, and the verdict must not be sеt aside unless there was no substantial evidence to support it. Fullerton v. Sauer,
Appellant did in fact make revisions in some of its literature as early as June 1960. Appellant’s Aralen “product card,” a card containing information about a particular drug, was changed to include the possibility of a side effect causing retinal damage. This revised product card was approved by the FDA in August 1960, and was thereafter distributed to doctors by appellant’s “detail men.” However, the jury could have found from the testimony that doctors do not regularly refer to these product cards, and quite possibly would not be aware of changes made in them. In January of 1963, too late to help appellee, appellant sent a letter to all doctors specifically calling their attention to the retinal side effects of Aralen. Appellant contends the letter was not sent sooner because the connection between the drug and the condition was not yet sufficiently established, and because some time was consumed in clearing the letter with the FDA. The whole question of the timeliness of appellant’s warning was, in our opinion, one upon which reasonable men сould differ. The question was therefore properly left ■to the jury, and there was no error in the trial court’s refusal to direct a verdict for appellant.
II.
Appellant raises several objections to the trial court’s instructions and refusal to give aрpellant’s requested instructions. In our opinion, only three of these objections merit discussion.
The first deals with the court’s instruction concerning appellant’s duty to warn appellee’s doctors of the side effect. The evidence at trial established that chloroquine retinopathy has been observed only in a very small percentage of those to whom the drug has been administered in the normally prescribed quantity. It appears that a small number of people are specially susceрtible to chloroquine. The court instructed the jury that if appellant knew or should have known that a group of persons would suffer rare side effects, appellant had a duty to warn the medical profession of the susceptibility of such a hypersensitivе or idiosyncratic group. Appellant insists that the duty to warn does not extend to those few individuals who are injured because
Under the facts of this case, we believe the better view is that appellant did have a duty to warn. The instant case is readily distinguishable from those cases denying relief to hypersensitive or idiosyncratic plaintiffs. Those сase cited by appellant deal with over the counter retail products. The denial .of relief seems to be based .on the unforeseeability of the injury and the futility of a warning even if given. It is said to be unreasonable to expect a manufacturer to foresee that some few persons among its many customers will suffer a rare allergic reaction to some ingredient in the product. See Merrill v. Beaute Vues Corp., supra
Appellant alleges that appellee’s doctors negligently failed to keep up with medical literature, including appellant’s, literature. It is argued that this negligence was an intervening proximate, cause of appellee’s injury, and that the trial court erred in failing so to instruct the jury. We find this argument without merit. There is no question of intervening proximate cause in this case. The sole issue was whether appellant negligently failed to make reasonable efforts, to warn appellee’s doctors. If appellant did so fail, it is liable regardless of anything the doctors may or may not have done. If it did not so fail, then it is; not liable for appellee’s injury. The issue was to be resolved by the jury, and. we see no error in the court’s instruction.
Appellant urges that the court erred in instructing the jury not to consider certain hearsay testimony to the
III.
The final issue in this appeal concerns the running of the applicable statute of limitations. Because of the Missouri borrowing statute, the statute of limitations we must consider is that of Kansas. Mo.Rev.Stat. § 516.190 (1959); Burgert v. Union Pac. R.R.,
The complaint in this case was filed November 26, 1963. The trial court denied appellant’s motion for a directed verdict, one of the grounds for which was the bar of limitations, and did not submit the question to the jury.
Appellant contends that the injury occurred in the late spring of 1961, when appellee first noticed a very small “golden light” which did not interfere with her vision. However, the medical testimony suggests that transient visual disturbances are not uncommon in patients undergoing Aralen treatment, and nothing in the record establishes that the small “golden light” was other than such a transient disturbance. There is no evidence that appellee suffered irrevеrsible impairment of vision before June 1962, when she barely avoided an automobile accident after failing to see another car, nor that she could have maintained a cause of action for permanent eye injury prior thereto.
Under Rulе 8, Fed.R.Civ.P., and Kansas law, the statute of limitations is an affirmative defense which must be pleaded and proved by the asserting party. Kan.Stat.Ann. § 60-208 (1965); Wilson v. Evans,
The judgment is affirmed.
Notes
. This more liberal view has since been adopted in Kansas by legislative amendment. See Kan.Stat.Ann. § 60-513 (1964).
