The maker of  a drink containing alcohol and caffeine was not liable to a woman allegedly injured when the driver of the motorcycle on which she was a passenger crashed, after the driver consumed the beverage.  See Cook v. MillerCoors LLC, No. 11-1488 (M.D. Fla., 10/28/11).

The operator of the motorcycle in the accident was killed, and plaintiff Cook, who was a passenger, was injured.  Prior to the crash, the driver allegedly had consumed several “Sparks”
alcoholic beverages containing caffeine and other stimulants, manufactured by defendant.

Cook argued that alcoholic beverages such as Sparks containing stimulants are “uniquely dangerous” because they appeal to younger drinkers and because the addition of caffeine enables one to drink more alcohol without feeling as intoxicated as one normally would. Thus, she alleged, consumers of these beverages are more likely to “engage in dangerous behavior such as driving.”  She asserted the driver did not appear impaired, even though toxicology reports from his autopsy revealed that his blood alcohol level was 0.10 at the time of the crash.

Defendant responded that the risks associated with operating a motor vehicle while under the influence of alcohol are well known; therefore, it could not be held responsible for the operator's choice to consume Sparks then illegally operate his motorcycle. The addition of other ingredients to the beverage did not lessen his responsibility to refrain from operating his motorcycle after having consumed the alcohol, and his actions, not the manufacture of Sparks,
proximately caused Cook’s injuries.  The crux of the defense motion to dismiss thus was that there is no cause of action against a manufacturer of alcoholic beverages for injuries resulting from their consumption because the effects of alcohol consumption are well known. With a response from plaintiff that the legion of such holdings in courts everywhere apply to “conventional” alcoholic beverages, not to an alcoholic beverage mixed with stimulants which allegedly suppress the consumer’s subjective awareness of alcohol’s well-known effects.

Regarding the failure to warn theory, a plaintiff must establish the existence of a duty. A manufacturer’s duty to warn arises when there is a need to inform consumers of dangers of which they are unaware.  The effects of alcohol and the need to not drink and drive are universally known.  While plaintiff argued about the unconventionality of this product, plaintiff did not and could not allege that the driver was unaware that he was drinking alcohol. His alleged subjective awareness of the speed or impact of those effects did not alter the legal reasoning of precedent that holds that there is no duty to warn because of the universal recognition of all potential dangers associated with alcohol. 

Plaintiff also failed to adequately allege how the product was unreasonably dangerous for the design defect claim. The effects of alcohol are universally and objectively well known, irrespective of the operator's alleged subjective awareness of them. The defectiveness of a design is determined based on an objective standard, not from the viewpoint of any specific user, said the court.

Moreover, plaintiff's theories failed as to proximate cause. Plaintiff alleged that the manufacturer's negligence caused the driver to become intoxicated to the point of impairment,
causing the crash and Cook’s injuries. In Florida, however, voluntary drinking of alcohol is the proximate cause of an injury from an intoxicated driver, rather than the manufacture or sale of those intoxicating beverages to that person.  This doomed the negligence claim.

Readers can readily see why the court was reluctant to make an exception to the rule for the "unconventional" beverage.  There are hundreds of alcohol-containing products that are not "conventional" in one way or another, by taste, ingredients, color, manufacturing process, advertising... To shift responsibility from the person who over-consumes one of these and then drives impaired is to send the absolutely wrong policy message.

Courts have typically recognized no duty on the maker, regardless of plaintiff's attempt to differentiate either themselves or the product. See, e.g., Malek v. Miller Brewing Co., 749 S.W.2d 521 (Tex. App. 1988) (finding no duty to warn despite claim that advertising led plaintiff to believe that “Lite” beer was less intoxicating than other beer); Pemberton v. Am. Distilled Spirits Co., 664 S.W.2d 690 (Tenn. 1984); Greif v. Anheuser-Busch Cos., Inc., 114 F. Supp. 2d 100 (D. Conn. 2000)(particular, alleged tolerance of an individual consumer); MaGuire v. Pabst Brewing Co., 387 N.W.2d 565 (Iowa 1986).

A West Virginia federal court has granted summary judgment against a plaintiff alleging that the heartburn drug metoclopramide caused her tardive dyskinesia.  Meade v. Parsley, et al., 2010 WL 4909435 (S.D.W.Va.,  11/24/10).

Since its approval by the Food and Drug Administration in 1980, metoclopramide has been widely used to treat gastroesophageal reflux disease (“GRD”), nausea, and gastroparesis.  Plaintiff's treater, Dr. Deidre Parsley, prescribed metoclopramide to Mrs. Meade in order to treat her
GRD, nausea, and loss of appetite. Plaintiff  never read any written materials accompanying her metoclopramide prescriptions, which included a statement that therapy longer than 12 weeks has not been evaluated and cannot be recommended.  Dr. Parsley likewise did not read the metoclopramide package insert or any other written materials produced by PLIVA before prescribing the drug to Mrs. Meade. After the drug usage, the FDA added a black box warning about tardive dyskinesia.  But, save for the placement of the warning in a black box, the previous warning seemed not too different.

Plaintiffs contended that the warnings were inadequate in that they misleadingly invited long term use that has never been approved by the FDA, despite the fact that the warning did state that therapy longer than 12 weeks has not been evaluated and cannot be recommended. In addition,
plaintiffs claim that the warnings downplayed the seriousness and potential irreversibility of the risk of tardive dyskinesia in long term use, but the warning did state that the risk is highest among the elderly, especially elderly women (like this plaintiff), and that the likelihood of irreversibility is believed to increase with the duration of treatment and the total cumulative dose. 

Defendant moved for summary judgment, contending that there were no genuine issues of material fact inasmuch as (1) plaintiffs could not establish causation; (2) Dr. Parsley was aware of the risks of using metoclopramide when she prescribed the drug to Mrs. Meade; (3) PLIVA satisfied any alleged duty to warn by providing a package insert explaining potential side effects of
metoclopramide.  The court never had to reach the third argument.

In a pharmaceutical products liability action, a plaintiff must initially establish both general and specific causation for his injuries. Bourne ex rel. Bourne v. E.I. Dupont de Nemours & Co., 189 F. Supp. 2d 482, 485 (S.D. W. Va. 2002).  General causation is whether a substance is capable of causing a particular injury or condition in the general population, while specific causation is whether a substance caused a particular individual's injury. In re Rezulin Prods. Liab. Litig., 369 F.
Supp. 2d 398, 402 (S.D.N.Y. 2005); In re Hanford Nuclear Reservation Litig., 292 F.3d 1124, 1129 (9th Cir. 2002). General causation is established by demonstrating, often through a review of scientific and medical literature, that exposure to a substance can cause a particular disease.

In addition to general and specific causation, plaintiffs must establish proximate causation.To
show proximate causation in a failure-to-warn case based on an allegedly inadequate drug label, a plaintiff must show that a different label or warning would have avoided the plaintiff’s injuries. The court noted that the West Virginia Supreme Court has not had occasion to clarify whether a drug manufacturer must warn both the patient and the physician, or just the patient.  But it did not need to resolve this issue in evaluating proximate causation, however, because the undisputed evidence shows that an adequate warning would not have changed either Mrs. Meade’s or Dr. Parsley’s behavior in a manner which would have avoided Mrs. Meade’s injury.  Rather than merely showing that “adequate warnings would have changed behavior,”  as plaintiff argued, plaintiffs must
establish that an adequate warning would have changed behavior in a manner which would have avoided the plaintiff’s injury.  Mrs. Meade testified that she never read the package insert or any other documents accompanying her metoclopramide prescription.  Dr. Parsley likewise testified that she did not read the metoclopramide warning. And while Dr. Parsley did read the PDR for
the brand name version of the drug, it is undisputed that the defendant did not create that PDR.

The more interesting part of the opinion for our readers is the treatment of the issue of general causation.  It seems that none of plaintiffs’ retained experts offered any opinions regarding general
causation. So plaintiffs were left to argue that several of Mrs. Meade’s treating physicians (whom plaintiffs began referring to as “non-retained experts”) testified regarding the causal link between metoclopramide and tardive dyskinesia. None of these non-retained experts provided written
reports, and in deposition none of these physicians testified directly as to general causation. They assumed causation as a prelude to a specific causation opinion, but this mere assumption does not establish general causation. The law is clear that a mere possibility of causation and, more
specifically, indeterminate expert testimony on causation that is based solely on possibility is not sufficient to allow a reasonable juror to find causation. 

As an alternative basis for general causation, plaintiffs tried to rely on the fact that defendant's own package inserts and brand name warnings refer to a "causal link” between metoclopramide and tardive dyskinesia. Plaintiffs could cite no authority for the proposition that a plaintiff in a pharmaceutical products liability case can satisfy his or her burden of proving general causation by relying on the defendant manufacturer’s drug label warnings. Moreover, this contention was undermined by the general principle that causation evidence in toxic tort cases must be in the form of expert scientific testimony.  PLIVA’s drug label, which merely warns of metoclopramide’s potential side-effects without explaining the scientific basis for the warning, was no substitute for expert testimony that establishes causation in terms of reasonable probability.

Third, plaintiffs also tried to cite, as evidence of general causation, the subsequent FDA directive requiring drug manufacturers to insert a black box warning on metoclopramide labels to convey a
greater risk of tardive dyskinesia. The court, as have several other courts have, however, rejected reliance on agency determinations as a basis for general causation. Inasmuch as the cost-benefit balancing employed by the FDA differs from the threshold standard for establishing causation in tort actions, this court likewise concluded that the FDA-mandated tardive dyskinesia warning cannot establish general causation.

 Summary judgment granted.

One of the fascinating and disturbing things about failure to warn claims is the endless supply of creative, far-fetched, fantastic, implausible, fanciful, incredible, questionable, even bizarre theories that plaintiff lawyers sometimes come up with to support this type of claim.

Last week, a Pennsylvania appeals court rejected just such a theory. Specifically, plaintiff alleged that a failure to warn caused her injury -- nothing strange there.  But the manufacturer DID warn specifically of the condition she developed.  So, what was the plaintiff's failure to warn theory?  That a drug maker may be liable for failure to warn despite warning of the condition plaintiff developed, because a warning about a different medical issue —one that she did not develop— would somehow have caused her doctor to not prescribe the drug.  Cochran v. Wyeth Inc., 2010 WL 2902717 (Pa. Super. Ct., 7/27/10).

Plaintiff ingested the prescription weight-loss drug dexfenfluramine, which was manufactured by Wyeth and sold under the brand name Redux. Wyeth informed the prescriber that Redux may cause primary pulmonary hypertension (“PPH”). The doctor, in turn, warned plaintiff of the risk of PPH prior to prescribing her Redux. At the time of his decision, however, the prescriber claimed he was unaware of the risk that Redux may cause valvular heart disease (“VHD”).  Later, plaintiff was diagnosed with PPH, which she had been warned about.  But she claimed that the doctor would not have prescribed Redux to her had he been warned that Redux could cause VHD.

Proximate cause is an essential element in a failure to warn case.  A proximate, or legal cause, is defined under Pennsylvania law as a substantial contributing factor in bringing about the harm in question. That is, a plaintiff must establish proximate causation by showing that had defendant issued a proper warning to the learned intermediary, he would have altered his behavior and the injury would have been avoided.   Wyeth argued that even if its warnings with regard to VHD were inadequate, its failure to warn of VHD was not the proximate cause of plaintiff's PPH.  To establish proximate causation, plaintiff must prove that the warnings failed to disclose the risk of her particular injury (PPH).

The trial court agreed. On appeal, the court found an absence of clear authority on the issue, but strong guidance in those cases that have addressed a plaintiff's burden of proving proximate causation in the informed consent context.  Finding the torts of informed consent and failure to warn analogous, the superior court was persuaded by those jurisdictions that have concluded a plaintiff cannot establish proximate causation where the non-disclosed risk never materialized into an injury.

Here, the risk of VHD did not develop into the actual injury of VHD. Although the prescriber testified in deposition that he would not have prescribed Redux had he known of the risk of VHD, this does not alter the fact that while Wyeth allegedly failed to disclose the risk of VHD the plaintiff suffered from PPH. In these circumstances, the relationship between the legal wrong (the alleged failure to disclose the risk of VHD) and the injury (PPH) was  "not directly correlative and is too remote" for proximate causation.

Summary judgment for defendant affirmed.
