Stevens-Johnson Syndrome in California: Can You Sue Over Suspect Medications?

What Are SJS and TEN—and Why They Matter Legally

Stevens-Johnson Syndrome (SJS) and Toxic Epidermal Necrolysis (TEN) are rare but severe reactions often associated with medications. They can involve extensive skin and mucosal injury, infection risk, and long-term complications, including scarring and vision loss. When a drug is the suspected cause, California product liability and negligence law may provide a path to compensation.

Who You Can Potentially Sue in California

• Drug manufacturers (brand-name or generic) for certain defect or warning theories (see, e.g., Greenman).
• Distributors and retailers in the chain of commerce under strict products liability principles (see Vandermark).
• Healthcare providers for professional negligence if prescribing, monitoring, or warning fell below the standard of care and caused harm (see Flowers).

Note: Pharmacies dispensing prescription medications are treated differently and are not strictly liable as sellers under California Supreme Court precedent (Murphy v. E.R. Squibb).

Key Legal Theories in Drug-Induced SJS/TEN Cases

• Failure to warn: Alleging inadequate warnings or instructions about SJS/TEN risks. For brand-name drugs, such claims are generally not preempted by federal law (Wyeth v. Levine).
• Design defect: California recognizes design-defect theories generally (see Barker), but strict-liability design-defect claims are generally unavailable for prescription drugs under comment k principles (Brown). Negligent design theories may still be argued depending on the facts.
• Manufacturing defect: A departure from the intended design or specifications caused the injury (see Jimenez).
• Negligence: Unreasonable conduct in research, testing, labeling, marketing, or pharmacovigilance.
• Medical negligence: Breach of the professional standard of care that causes injury (see Flowers).

Special Considerations for Generic Drugs

Federal preemption can restrict certain claims against generic manufacturers, because their labels must mirror the brand’s and they cannot unilaterally change design or warnings (PLIVA v. Mensing; Mutual v. Bartlett). Depending on the facts, other avenues may exist:

• Claims against brand-name manufacturers for negligent failure to warn may be viable in California even when the injured person took a generic drug (T.H. v. Novartis).
• Brand-name failure-to-warn claims are generally not preempted (Wyeth v. Levine).

Proving Causation in SJS/TEN Claims

Causation is often the central battleground. Plaintiffs typically rely on:

• Medical records documenting onset relative to medication exposure, and differential diagnosis.
• Expert testimony (dermatology, pharmacology, toxicology, ophthalmology) addressing causation and alternatives.
• Scientific literature, post-market safety data, adverse event reports, and labeling history.

Evidence to Collect Right Away

• Complete medication history (prescription, OTC, supplements), lot numbers if available, and start/stop dates.
• Hospital/burn unit records, biopsy/pathology results, ophthalmology evaluations, and photographs.
• Packaging, inserts, and pharmacy printouts.
• Insurance EOBs and billing records (economic losses).
• Work records for lost income.
• A contemporaneous journal of symptoms and functional limitations.

Potential Damages

Recoverable damages may include medical expenses (past and future), lost income and earning capacity, pain and suffering, disfigurement, and loss of consortium where applicable. Punitive damages may be available with proof of malice, oppression, or fraud (Civ. Code § 3294).

Practical Tips

Timing Matters: Don’t Wait to Speak With Counsel

Deadlines are critical and depend on the claim and facts. California’s general personal-injury statute of limitations is two years (CCP § 335.1). Medical malpractice claims have a separate statute that includes a one-year discovery rule and an outside limit in most cases (CCP § 340.5). Specific deadlines and tolling rules vary—consult counsel promptly.

FAQ

Do I have a case if I took a generic drug?

Possibly. Some claims against generic manufacturers are limited by federal preemption, but California permits certain negligence claims against brand-name manufacturers in specific circumstances even if you took a generic.

How do I prove a medication caused my SJS/TEN?

Causation typically relies on medical records, expert testimony, timing of exposure, and ruling out alternative causes, supported by scientific literature and safety data.

What compensation can I seek?

Medical costs, lost income, pain and suffering, disfigurement, loss of consortium, and potentially punitive damages where legally supported.

How long do I have to file?

Deadlines vary by claim. Many personal injury claims are two years; medical malpractice has different discovery and outside limits. Speak with a California attorney promptly.
