Miami Singulair Lawyer

Singulair (montelukast) spent years as a widely prescribed asthma and allergy medication before the FDA required its strongest warning label, a black box warning, alerting patients to serious neuropsychiatric side effects. For many families in Miami, that warning came too late. If you took Singulair and experienced depression, suicidal thoughts, aggression, hallucinations, or other severe mental health changes, you may have a valid product liability claim against the manufacturer. Spencer Morgan Law has represented injured people throughout South Florida since 2001, and the firm brings that same Miami Singulair lawyer approach to pharmaceutical cases that it has applied to every serious injury matter: pursue the facts hard, hold the responsible party accountable, and make sure clients understand exactly what is happening at every stage.

What Merck Knew and When It Knew It

Singulair was first approved in 1998, and concerns about neuropsychiatric events appeared in post-market reports within the first several years on the market. Merck, the drug’s manufacturer, received adverse event reports describing suicidal behavior, self-injury, anxiety, sleep disturbances, and tremors. For more than two decades, those warnings were either buried in prescriber information or presented in language that failed to convey the genuine risk to patients and parents of pediatric patients.

The FDA updated Singulair’s label in 2008 to include a neuropsychiatric warning and again in 2020 to impose the black box standard, restricting use in mild cases where alternatives exist. That 2020 action was a tacit acknowledgment that the prior warnings were inadequate. Product liability law in Florida focuses heavily on whether a manufacturer adequately warned users of known risks. When a company has internal data about a serious danger and chooses to downplay it in labeling, that is the kind of failure courts examine closely. The gap between what Merck knew and what it told doctors and patients is central to these claims.

Who May Have a Claim and What the Injuries Look Like

Not every person who took Singulair will have a viable case, and part of what an attorney does early on is evaluate whether the facts connect the medication to a compensable injury. The people most likely to have strong claims are those who experienced neuropsychiatric symptoms while taking the drug, saw those symptoms resolve or improve after stopping it, and did not have a pre-existing psychiatric condition that fully accounts for the harm.

• Patients who developed suicidal ideation or made attempts while on Singulair and had no prior psychiatric history
• Children prescribed montelukast for allergies who exhibited severe behavioral changes, aggression, or self-harm
• Adults who experienced severe depression, anxiety, or sleep disorders that emerged after starting the medication
• Patients whose prescribing physician was not adequately informed by Merck of the known neuropsychiatric risks at the time of prescription
• Family members who lost someone to suicide that occurred during or shortly after Singulair use

The injuries in these cases are not minor. Psychiatric trauma, hospitalization, suicide attempts, and the long-term consequences of untreated mental health crises can affect every aspect of a person’s life. Lost income, ongoing therapy costs, the impact on relationships and careers, and in the most devastating cases, wrongful death, all factor into the damages calculation. Florida law allows recovery for economic losses and non-economic harms like pain and suffering, and in cases involving particularly egregious corporate conduct, punitive damages may also be available.

Florida Product Liability Law and How It Applies to Pharmaceutical Claims

Florida recognizes product liability claims under several theories, but pharmaceutical injury cases typically rely on failure to warn. The argument is straightforward: a drug manufacturer has a duty to provide adequate warning of known risks, and when that duty is breached, the company is liable for injuries that result. The legal concept is sometimes called the “learned intermediary doctrine,” meaning drug companies often argue they only had to warn prescribing doctors, not patients directly. Florida courts have applied this doctrine with some nuance, and plaintiffs’ attorneys push back on it when evidence shows the company marketed directly to consumers or when the physician was not meaningfully informed.

Florida’s statute of limitations for product liability claims is generally four years from the date of injury. However, the clock does not always start ticking on the day harm occurred, particularly in pharmaceutical cases where the connection between a drug and a psychiatric symptom is not immediately obvious. The discovery rule allows the limitations period to begin when a plaintiff knew or should have known that their injury was connected to the product. Given that many Singulair users spent years attributing their symptoms to other causes, the question of when the limitations period began is one an attorney needs to analyze carefully for each individual situation.

Florida is also a pure comparative fault state, meaning that even if a defendant argues a plaintiff was partially at fault, compensation can still be recovered. In pharmaceutical cases that argument rarely holds much weight, but it underscores that perceived complications in the facts should not discourage someone from having their case evaluated.

Multi-District Litigation and What That Means for Your Case

Singulair litigation has been consolidated into federal multi-district litigation proceedings, which is a common mechanism for managing large numbers of similar pharmaceutical injury cases across the country. MDL consolidation does not mean individual cases lose their independent identity. Each plaintiff’s injuries, damages, and facts remain specific to that person. What consolidation does is streamline pretrial discovery and motion practice so that the same foundational questions about Merck’s conduct are not relitigated in courts across fifty states simultaneously.

For someone in Miami evaluating whether to pursue a claim, MDL proceedings carry practical implications. The litigation moves according to a coordinated schedule, and the strength of individual claims often depends on how well the plaintiff’s attorneys have documented injuries, gathered medical records, and established the link between the medication and the psychiatric harm. Firms that handle these cases on a volume basis with minimal individual attention tend to produce weaker results. Spencer Morgan Law takes a different approach: the personal attention that the firm’s clients consistently describe in their own words is the same attention that builds the factual record a Singulair claim requires.

Questions People Ask Before Contacting a Singulair Attorney

Does it matter that I stopped taking Singulair years ago?

Not necessarily. The statute of limitations analysis and the discovery rule mean that some claims remain viable even when the medication was discontinued years before the connection to psychiatric harm was recognized. The specific timeline matters, and that is exactly the kind of analysis worth having with an attorney before assuming a claim has expired.

My doctor prescribed Singulair and never mentioned these risks. Does that affect my case?

It can support it. When a physician was not adequately informed by the manufacturer of known risks, the learned intermediary doctrine does not protect the company as effectively. Your physician’s prescribing decisions and what information they received from Merck are relevant pieces of the evidentiary picture.

Singulair is now generic. Can I still sue Merck?

Brand name manufacturers like Merck can face liability for failure to warn claims even after generic versions enter the market, because the branded manufacturer controlled the original labeling. The generic versus brand distinction in pharmaceutical litigation is complicated, and the facts of when you took the medication and which version you took matter significantly.

What kind of documentation should I gather before consulting an attorney?

Pharmacy records showing Singulair prescriptions, medical records documenting psychiatric symptoms, records of hospitalizations or mental health treatment, and any documentation of when symptoms began and improved are all valuable. Spencer Morgan Law can help identify what else may be needed once the firm reviews the initial facts.

Will I have to go to trial?

Most pharmaceutical mass tort cases resolve through settlement, either individually or through global resolution processes in MDL proceedings. That said, having an attorney prepared to litigate aggressively affects the quality of any settlement negotiation. No attorney can guarantee an outcome, but the quality of case preparation shapes what outcomes become available.

How does the fee arrangement work?

Spencer Morgan Law handles personal injury and product liability cases on a contingency fee basis. That means the firm does not get paid unless a recovery is made for the client. There is no upfront cost to consult with the firm or to have your case evaluated.

What if my loved one died and we believe Singulair played a role?

Florida’s Wrongful Death Act allows certain surviving family members to bring claims when a person dies due to another party’s negligence or misconduct. These claims have their own procedural requirements and timelines, and consulting with an attorney as soon as possible is important for preserving the family’s options.
