Malachy J. Smyth, M.D., and his wife seek a new trial of their diversity action in the Northern District of New York against The Upjohn Co. for personal injuries suffered by Dr. Smyth, allegedly as the result of Upjohn’s antibiotic Lin-cocin. The complaint alleges that Dr. Smyth developed acute colitis as a result of his taking Lincocin, and that Upjohn was negligent in failing to give adequate warnings of this possible side-effect. A jury trial before Edmund Port, Judge, resulted in a verdict for Upjohn. We affirm.
In February 1970, Dr. Smyth developed sinusitis and began treating himself with Lincocin. After administering the drug to himself for two days he developed diarrhea. He continued the medication for two more days. However, after he stopped taking Lincocin, his diarrhea grew progressively worse; he also developed a severe sore throat and lost weight. He then treated his condition with other drugs for six weeks until March 19, when he consulted another physician, who hospitalized him. Dr. Smyth’s condition improved after continued treatment in and out of hospitals for what was ultimately diagnosed as colitis.
The only issue raised on this appeal is whether the district court erred in refusing to admit into evidence certain warnings Upjohn published about Linco-cin’s side-effects. While the warning

read by Dr. Smyth before taking the drug was admitted into evidence, those published after the incident were not;

these later warnings, issued from 1970 to 1974, cautioned physicians in progressively severer terms about Lincocin’s side-effects.

The district court excluded these later warnings, applying the doctrine of “subsequent repairs,” which holds that evidence of remedial action taken by a defendant after an accident or other occurrence should not be admitted as proof that the mishap was due to his negligence. Both parties have argued the case on the basis that the evidence was excludable if a New York court would have excluded it.

The New York courts have long adhered to the “subsequent repairs” doctrine. See, e. g.,
Getty
v.
Town of Hamlin,
Appellants, directing their attention principally to the public policy reasoning behind the rule, argued that the New York courts would make an exception to the doctrine in a case involving a mass-produced product such as Lincocin since the producers would in any event make the repairs or remedy the condition. See
Ault
v.
International Harvester Co.,
Thus once again, because we are compelled to accept diversity jurisdiction and the New York courts do not appear to have faced this precise contention, we must speculate as to what principle would be applied by the state courts. See
Feldman v. Allegheny Airlines, Inc.,
The arguments advanced by appellants are hardly of sufficient compelling force to persuade us that the New York Court of Appeals would make a general exception for mass-produced products. While the public policy justification for the exclusion of subsequent repair evidence, i. e., discouragement of such repairs, may be less forceful in cases involving such products than in other cases (and this has by no means been established), it still has some weight. Some manufacturers might still decide that the risk of increased liability arising from admission of subsequent repairs or warnings would so outweigh the risks posed by adherence to the status quo that they would opt for the latter. Moreover, appellants ignore the other justifications for the “subsequent repairs” rule, which were summarized by the Supreme Court in
Columbia & Puget Sound Railroad Co. v. Hawthorne,
“[T]he evidence is incompetent, because the taking of such precautions against the future is not to be construed as an admission of responsibility for the past, has no legitimate tendency to prove that the defendant had been negligent before the accident happened, and is calculated to distract the minds of the jury from the real issue, and to create a prejudice against the defendant.”
Appellants point to no countervailing probative value in the evidence, which would offset its possible prejudice to the defendant in the present case. It is true that such post-accident warnings have been admitted by some courts to prove the state of a manufacturer’s knowledge of the dangers of a product prior to the incident, see
Sterner v. U. S. Plywood-Champion Paper Inc.,
In sum, even if we adopt a more relaxed view of the “subsequent repairs” doctrine than the New York cases suggest, and balance the prejudice to the defendant against the probative value of the evidence, we think that excluding the evidence was well within the trial court’s “broad discretion over the admissibility of evidence.”
Sterner
v.
U. S. Plywood-Champion Paper Inc., supra,
We accordingly affirm the decision below.
Notes
. Counsel for Smyth actually offered only the first of these later warnings into evidence, although he argued before the trial judge that all of them should be admitted. Since we believe that the admissibility of all the warnings must be decided on the same ground, we treat the case as if all had been offered.
. The differences between the warning read by Dr. Smyth and the first warning published aft-erwards are somewhat elusive. The warning he read indicated that Lincocin might cause “persistent diarrhea” and “enterocolitis.” The next warning, published later in 1970, stated in addition that the drug might cause “acute colitis.” There was expert testimony at trial that enterocolitis, which refers to inflammation of the small and large intestines, would, as a medical term, encompass colitis, an inflammation only of the large intestine. Later warnings expanded on the possible side-effects of Lincocin, until by 1974, the warning included recommendations for treatment of the side-effects.
. See F.R.Civ.P. 43(a). The trial took place before the effective date of the Federal Rules of Evidence. No federal statute requires admission of the evidence. Moreover appellant has made no effort to show that the subsequent warnings would be admissible under the rules of evidence heretofore applied in the courts of the United States on the hearing of suits in equity.” See
