Opinion:
PER CURIAM:
In this Mississippi diversity suit a jury returned a verdict of $800,000 against defendant Pfizer, Inc. as compensation for plaintiff Laura Hermes' personal injury resulting from the use of the prescription drug Sinequan, a Pfizer product. We reject Pfizer's arguments that the evidence of the drug's potential side effect was insufficient to trigger a duty to warn and that there was insufficient evidence that the drug was a cause of injury, and we affirm.
I
A gynecologist prescribed Sinequan, a tricyclic antidepressant, for Laura Hermes, a 50-year old post-hysterectomy patient. Several days after taking the medication, Hermes developed "extrapyramidal" symptoms or a "hunting jaw." Hermes sought treatment by an oral surgeon who referred her to a neurologist. The condition appears to be permanent.
Hermes filed this suit against Pfizer alleging strict liability and negligence. Hermes offered the testimony of Dr. Dewey Metts, the oral surgeon, Dr. Joe Jackson, the treating neurologist, Dr. Michael Bourgeois, the prescribing gynecologist, Dr. James O'Donnell, an expert in adverse drug reactions and licensed pharmacist, and, as an adverse witness, Salvatore Gior-giani a Pfizer employee responsible for maintaining adverse drug reactions reports. Pfizer presented the testimony of Dr. James Matheny, an expert in pharma cology. Dr. Armin Haerer, a neurologist who examined Hermes under court order, also testified at trial.
II
Pfizer argues that the court erred in denying its motions for directed verdict, judgment n.o.v., and new trial because the evidence on the issues of duty to warn and causation was insufficient to support a jury verdict. On review of a motion for directed verdict or judgment n.o.v., we apply the test announced in Boeing Co. v. Shipman, whether, in a light most favorable to the party opposing the motion, reasonable people could not arrive at a contrary verdict. In reviewing a motion for new trial, we ask whether the verdict is against the great weight of the evidence.
A
A key issue in this appeal is whether Pfizer had a duty to warn Hermes of the possible side effect she experienced, whether it knew or should have known that the taking of Sinequan could cause permanent hunting jaw. Whether there is a duty to warn turns on the manufacturer's actual knowledge and its "constructive knowledge as measured by scientific literature and other available means of communication." A manufacturer has a duty to keep abreast of research, adverse reaction reports, and other scientific literature pertaining to its product.
Pfizer argues that there was insufficient evidence of any knowledge of the possible side effect. It argues that not one expert testified that there had been any report of symptoms such as those experienced by Hermes. It cites to Johnston v. Upjohn Co., in which the court held that "if such a reaction had never occurred before, defendant could not know about it or in the exercise of the required degree of care could not have found out about it, and absent knowledge of such reaction, there could be no duty to warn."
Pfizer argues that in any event there is no evidence that it breached any duty to warn, pointing to its instructions insert and reference in Physician's Desk Reference, which noted the possibility of temporary extrapyramidal symptoms. Pfizer contends that it had no duty to warn of permanent symptoms because it "knew" of none.
Hermes argues, on the other hand, that Pfizer knew or should have known of the side effect. Her expert, O'Donnell, unequivocally stated that Sinequan could cause temporary and permanent hunting jaw. The jury also had before it an FDA computer printout of adverse drug reaction reports concerning Sinequan, evidence that reports of extrapyramidal symptoms were recorded as early as 1970.
We are persuaded that this evidence was enough for the jury to have concluded that Pfizer had sufficient knowledge to trigger a duty to warn. The court did not err in denying Pfizer's motion on this ground.
B
A second key issue in this appeal is causation: whether her ingestion of the drug was the proximate cause of her injury and whether Pfizer's failure to warn was the cause in fact of Mrs. Hermes' ingesting Sinequan. The jury was instructed as follows:
The plaintiff Laura Hermes has the burden of proving by a preponderance of the evidence, one, that her taking of Sine-quan caused in fact the injury com plained of and, two, that the warning, if any, given by Pfizer to plaintiffs prescribing physician was inadequate and, three, that had an adequate warning been given, a reasonably prudent physician would not have prescribed Sine-quan.
Pfizer contends that Hermes failed to meet her burden as to cause in fact because the only evidence on this point was O'Donnell's testimony that Hermes' symptoms were caused by the ingestion of Sinequan. It contends that while generally a question relating to the base of an expert's opinion should be left to the jury, there was no foundation for O'Donnell's conclusions.
In Viterbo v. Dow, we noted the general rule cited by Pfizer but held:
In some cases, however, the source upon which an expert's opinion relies is of such little weight that the jury should not be permitted to receive that opinion. Expert opinion testimony falls into this category when that testimony would not actually assist the jury in arriving at an intelligent and sound verdict.... If an opinion is fundamentally unsupported, then it offers no expert assistance to the jury. Furthermore, its lack of reliable support may render it more prejudicial than probative, making it inadmissible under Fed.R.Evid. 403.
Pfizer argues that under Viterbo, O'Donnell's testimony should not have gone to the jury. Basically, Pfizer argues that Hermes' "expert" wasn't and that no other medical doctor testified that Sinequan caused Hermes' problems.
We are not persuaded that O'Donnell's testimony was so unfounded that the jury should not have been presented with this evidence. There is nothing that generally disqualifies a non-physician as an expert on causation. Furthermore, the oral surgeon, Dr. Metts, also testified that his mother had had a similar reaction to Sine-quan and that her symptoms had ceased once he took her off the medication. This was enough evidence to submit the issue to the jury.
Finally, Pfizer argues that Hermes did not meet her burden of establishing that had an adequate warning been given, a reasonably prudent physician would not have prescribed Sinequan for her. On this point, the jury was presented with the evidence of Dr. Metts, who testified that he took his mother off Sinequan once she experienced symptoms like Mrs. Hermes experienced, Dr. O'Donnell, who testified that in his opinion "if an adequate warning would have been given, she would not have the injuries she has today," and Dr. Haerer, who testified that, based on the information then contained in the Physi- dan's Desk Reference, he would prescribe Sinequan for treatment of "[s]ome type of symptom that could only be helped by that drug." When viewed in the light most favorable to Hermes, this evidence was sufficient to allow the jury to decide the issue of causation, and when combined with a jury's permissible inferences, was sufficient to support the jury's determination that had an adequate warning been given, a reasonably prudent physician would not have prescribed Sinequan for Mrs. Hermes.
We AFFIRM.
. We note that although Pfizer originally appealed the $800,000 damage award on the ground that it was excessive, the parties since the briefs were filed have executed a liquidated damages agreement. Thus, the amount of the jury award is no longer at issue.
