What is the Singulair lawsuit about?
The Singulair lawsuit alleges that Merck failed to warn about serious neuropsychiatric side effects like depression and suicidal thoughts. Victims are seeking compensation for the harm caused. A Singulair lawsuit lawyer can help you pursue your claim and navigate the legal process.
What Is Singulair?
Singulair, known generically as montelukast, entered the market as a beacon of hope for millions suffering from asthma and allergies. Manufactured by Merck & Co., this medication quickly became a go-to prescription for both adults and children seeking relief from chronic respiratory issues. Its once-daily dosing and non-steroid formulation made it an attractive option for many patients and healthcare providers alike.
However, recent years have seen a dramatic shift in the narrative surrounding Singulair. Disturbing reports of serious neuropsychiatric events among users, particularly children and young adults, have cast a shadow over the drug's reputation. These concerns have led to intense scrutiny, FDA warnings, and a wave of lawsuits against the manufacturer.
Reported Side Effects of Singulair
While Singulair has helped many manage their asthma and allergies, there are potential risks associated with its use. The Singulair side effects that have come to light strike at the core of a person's mental health and well-being, often with devastating consequences.
Mental Health Issues
- Depression
- Anxiety
- Mood swings
- Sleep disturbances
Neuropsychiatric Events
- Suicidal thoughts and behaviors
- Hallucinations
- Memory problems
- Confusion
These side effects can be particularly distressing because they often appear suddenly and can be severe. For parents whose children have been prescribed Singulair, watching their child struggle with these symptoms can be heart-wrenching. Adults who experience these effects may find their careers, relationships, and quality of life dramatically impacted.
FDA Warnings About Singulair
The FDA's actions over the years reflect a gradual acknowledgment of the risks associated with this widely prescribed medication.
Timeline of FDA actions:
- 2008: The FDA began investigating reports of mood and behavioral changes in patients taking Singulair.
- 2009: The agency required Merck to update Singulair's prescribing information to include information about neuropsychiatric events.
- 2020: In a significant move, the FDA required Merck to add a Boxed Warning – their strongest warning – to Singulair's labeling.
Black Box Warning
The FDA's decision to require a Boxed Warning for Singulair was a watershed moment. This warning, often referred to as a "black box warning," is reserved for prescription drugs that carry serious or life-threatening risks. For Singulair, the warning explicitly states that the drug should not be used in patients with mild symptoms, particularly allergic rhinitis.
The warning highlights the risk of serious mental health side effects, including:
- Agitation
- Depression
- Sleep problems
- Suicidal thoughts and actions
The FDA advises healthcare providers to alert patients about these risks and to advise them to stop the medication and contact a healthcare provider immediately if they experience any changes in behavior or mood.
This strong stance by the FDA underscores the severity of the potential side effects and has been a crucial factor in the surge of Singulair lawsuits.
Basis for Lawsuits
The wave of Singulair lawsuits sweeping across the nation is rooted in deeply troubling allegations against the drug's manufacturer, Merck & Co. These legal actions reflect the pain, suffering, and sense of betrayal many patients and their families feel who trusted the safety of this widely prescribed medication.
Allegations against the manufacturer include:
- Negligence: Plaintiffs argue that Merck failed to adequately research the long-term effects of Singulair, particularly its impact on mental health.
- Defective design: Some lawsuits claim that Singulair is inherently dangerous due to its chemical composition and mechanism of action.
- Fraudulent misrepresentation: Accusations that Merck downplayed or concealed known risks associated with the drug to maintain its market share.
Failure to Warn Claims
At the heart of many Singulair lawsuits is the allegation that Merck failed to warn patients and healthcare providers about the full extent of the drug's risks. Specifically:
- Inadequate labeling: Plaintiffs argue that the original warnings on Singulair's packaging were insufficient, burying critical information about neuropsychiatric risks.
- Delayed action: Despite early indications of serious side effects, it took years for strong warnings to be implemented, potentially putting countless patients at risk.
- Targeting vulnerable populations: Many lawsuits focus on the marketing of Singulair to children and young adults, who may be particularly susceptible to its neuropsychiatric effects.
These lawsuits seek to secure compensation for those harmed and to hold Merck accountable for its alleged actions and omissions.
Current Status of Litigation
The legal landscape surrounding Singulair is dynamic and evolving, with new developments unfolding regularly.
Individual Lawsuits
- Numerous individual lawsuits have been filed across the country, each telling a unique story of harm and seeking justice.
- These cases range from mild neuropsychiatric effects to tragic instances of suicide allegedly linked to Singulair use.
- Some early cases have seen settlements, though the terms are often confidential.
Potential for Mass Tort or Class Action
Given the widespread nature of Singulair use and the commonality of alleged injuries, there's growing momentum toward consolidating cases into a mass tort or multidistrict litigation (MDL).
Discussions are underway about forming a multidistrict litigation (MDL) to streamline the legal process for the numerous Singulair cases.
An MDL would allow for more efficient handling of pretrial proceedings while preserving the individuality of each case.
As more individuals come forward with their Singulair experiences, the legal landscape continues to change. The potential for a large-scale legal action grows, which could significantly impact plaintiffs’ chances of receiving compensation.
Who May Be Eligible to File a Singulair Lawsuit
If you or a loved one suffered adverse effects from taking Singulair, you may be wondering about your eligibility to seek legal recourse. Consider the following:
Criteria for Potential Plaintiffs
- You must have been prescribed and taken Singulair (montelukast) for asthma, allergies, or other approved uses.
- You should have suffered from neuropsychiatric side effects such as depression, anxiety, aggressive behavior, or suicidal thoughts.
- Your use of Singulair should have occurred before you were fully informed of these potential side effects.
- Your attorney must show that the side effects led to tangible harm, such as medical expenses, lost wages, or diminished quality of life.
Statute of Limitations
Each state has its own statute of limitations for product liability and personal injury cases. You must consult an attorney in your state quickly to ensure you don’t miss important deadlines for filing a claim.
In many cases, the clock starts ticking when you first discovered (or reasonably should have discovered) that Singulair may have caused your injuries.
As litigation progresses, courts may make rulings that affect time limits for filing, so you must stay informed.
An attorney can help you understand your specific situation in light of current laws and litigation status.

Potential Compensation You Could Receive
Pursuing a Singulair lawsuit can provide crucial financial support and a sense of justice. Understanding the types of damages you might be eligible for can help set realistic expectations and guide your decision-making process.

- Compensation for the inability to engage in activities and hobbies you once enjoyed.
Factors Affecting Compensation
- Severity of side effects: More severe and long-lasting effects typically result in higher compensation.
- Age of the plaintiff: Younger plaintiffs who face a lifetime of challenges may receive larger awards.

- Strength of evidence: Clear documentation linking Singulair to your symptoms can strengthen your case.
