NOTICE: SLIP OPINION

(not the court’s final written decision)

The opinion that begins on the next page is a slip opinion. Slip opinions are the written opinions that are originally filed by the court. A slip opinion is not necessarily the court’s final written decision. Slip opinions can be changed by subsequent court orders. For example, a court may issue an order making substantive changes to a slip opinion or publishing for precedential purposes a previously “unpublished” opinion. Additionally, nonsubstantive edits (for style, grammar, citation, format, punctuation, etc.) are made before the opinions that have precedential value are published in the official reports of court decisions: the Washington Reports 2d and the Washington Appellate Reports. An opinion in the official reports replaces the slip opinion as the official opinion of the court. The slip opinion that begins on the next page is for a published opinion, and it has since been revised for publication in the printed official reports. The official text of the court’s opinion is found in the advance sheets and the bound volumes of the official reports.

OWENS, J. — Under the learned intermediary doctrine, a prescription drug manufacturer satisfies its duty to warn patients of a drug’s risks when it adequately warns the prescribing physician. The United States District Court for the Western District of Washington asks us via certified question whether Washington law recognizes an exception to the learned intermediary doctrine when a prescription drug

Dearinger v. Eli Lilly, No. 99956-2

manufacturer advertises its product directly to consumers. We answer this question in the negative: there is no direct-to-consumer advertising exception. The policies underlying the learned intermediary doctrine remain intact even in the direct-to- consumer advertising context. Further, existing state law sufficiently regulates product warnings and prescription drug advertising. Accordingly, we hold regardless of whether a prescription drug manufacturer advertises its products directly to consumers, the manufacturer satisfies its duty to warn a patient when it adequately warns the prescribing physician of the drug’s risks and side effects.

I. FACTS AND PROCEDURAL HISTORY Plaintiff David Dearinger alleges he suffered a hemorrhage leading to a stroke that caused him permanent disabilities less than two hours after consuming Cialis. Cialis is a prescription drug manufactured by defendant Eli Lilly and Co. (Lilly) to treat prostatic hyperplasia, pulmonary arterial hypertension, and erectile dysfunction.

Dearinger sued Lilly in federal court under the Washington products liability act (WPLA), chapter 7.72 RCW, for negligent design, negligent failure to warn, and breach of warranty.1 The theory central to Dearinger’s claims is that Lilly knew or should have known Cialis presented a risk of stroke to its users and failed to adequately warn users of this risk.

1 Ganna Dearinger, Dearinger’s wife, also brought a claim for loss of consortium.

Dearinger v. Eli Lilly, No. 99956-2

Lilly moved to dismiss the complaint, claiming it provided adequate warnings to Dearinger’s prescribing physician under the learned intermediary doctrine. In response, Dearinger claimed there is an exception to the learned intermediary doctrine for drug manufacturers who advertise directly to consumers. But no Washington court has considered this exception. Accordingly, Dearinger moved for the United States District Court to certify a question to this court asking whether Washington law recognizes such an exception, which the court granted.

Three amicus curiae submitted briefs. The Washington State Association for Justice Foundation (WSAJF) filed a brief in support of Dearinger, while the Pharmaceutical Research and Manufacturers of America (PhRMA) and the Washington Defense Trial Lawyers submitted briefs supporting Lilly. Additionally, counsel for WSAJF and PhRMA presented oral argument before the court.

II. CERTIFIED QUESTION PRESENTED 2 Does Washington law recognize an exception to the learned intermediary doctrine that requires prescription drug manufacturers to warn patients, not just prescribing physicians, when the manufacturer directly advertises to consumers? We review certified questions de novo. In re F5 Networks, Inc., 166 Wn.2d 229, 236, 207 P.3d 433 (2009).

2 We have the authority to reformulate certified questions. Danny v. Laidlaw Transit Servs., 165 Wn.2d 200, 205, 193 P.3d 128 (2008) (plurality opinion). We exercise this authority here for clarity.

III. ANALYSIS

A. The Learned Intermediary Doctrine Is Settled Law in Washington 1. Washington Adopted the Doctrine through the Common Law This case ultimately centers on product liability, which is governed by the WPLA. Under the WPLA, a product manufacturer may be liable for failing to provide adequate warnings about a product if it harms the user. RCW 7.72.030(1). Thus, a manufacturer has a duty to warn of dangers associated with using a particular product. Id. This case raises the question of who the manufacturer must warn.

In the context of prescription drugs, the learned intermediary doctrine provides “the manufacturer satisfies its duty to warn the patient of the risks of its product where it properly warns the prescribing physician.” Taylor v. Intuitive Surgical, Inc., 187 Wn.2d 743, 757, 389 P.3d 517 (2017) (citing Terhune v. A.H. Robins Co., 90 Wn.2d 9, 14, 577 P.2d 975 (1978)). In other words, “[t]he manufacturer’s duty to provide warnings to patients transfers to the doctor, who is in a better position to communicate them to the patient.” Id.

The learned intermediary doctrine has been a fixed part of Washington law since this court adopted it in Terhune in 1978. Courts applying the learned intermediary doctrine have done so without recognizing an exception. See Sherman v. Pfizer, Inc., 8 Wn. App. 2d 686, 440 P.3d 1016 (2019), review denied, 194 Wn.2d 1015 (2019); see also Luttrell v. Novartis Pharm. Corp., 894 F. Supp. 2d 1324, 1342 (E.D. Wash. 2012) (court order), aff’d, 555 F. App’x 710 (9th Cir. 2014). Indeed, we

Dearinger v. Eli Lilly, No. 99956-2

have consistently reiterated Terhune’s central principle that a manufacturer satisfies its duty to warn patients of product risks by warning the prescribing physician, who then takes on the responsibility of communicating those warnings to the patient. Taylor, 187 Wn.2d at 757-58; Young v. Key Pharm., Inc., 130 Wn.2d 160, 168, 922 P.2d 59 (1996) (plurality opinion); Ruiz-Guzman v. Amvac Chem. Corp., 141 Wn.2d 493, 506, 7 P.3d 795 (2000); Rublee v. Carrier Corp., 192 Wn.2d 190, 208-09, 428 P.3d 1207 (2018).

Washington is far from alone in adopting the learned intermediary doctrine.
