The FDA's Black Box Warning and Suicide Risk
One of the most serious and highly publicized controversies surrounding Lexapro, and other selective serotonin reuptake inhibitors (SSRIs), is the increased risk of suicidal thoughts and behaviors in young people. In 2004, the FDA mandated a black box warning—the agency's most stringent warning—on antidepressant labels to highlight this risk in pediatric patients. This warning was later expanded to include young adults up to age 24, as studies indicated that the risk of suicidality was particularly elevated in the first few months of treatment or following a dosage change.
This FDA action followed legal pressure and public scrutiny, including lawsuits alleging that manufacturers, including Lexapro's maker, failed to adequately warn consumers about the risk. For example, the family of a Virginia teenager who died by suicide after starting Lexapro treatment filed a lawsuit alleging the drug contributed to his death. Furthermore, the manufacturer, Forest Laboratories (now Allergan), faced legal consequences for illegally marketing Lexapro for unapproved, off-label uses in children before it was officially approved for adolescents.
Lexapro and Pregnancy: Balancing Risks
Another major point of contention centers on the use of Lexapro during pregnancy and the potential risk of birth defects. Lawsuits and FDA advisories have highlighted concerns about potential congenital defects linked to SSRI exposure in utero. Alleged defects include cardiac issues, cleft lip and palate, and persistent pulmonary hypertension of the newborn (PPHN), a serious lung condition.
- Conflicting Evidence: The evidence surrounding this risk has been mixed. While some studies have suggested a link, particularly for use during the later stages of pregnancy, other research has offered conflicting results or found the overall risk to be minimal.
- Risk-Benefit Analysis: This conflicting information places expectant mothers and their doctors in a difficult position. Untreated depression during pregnancy also carries significant risks for both the mother and the baby. Therefore, healthcare providers must carefully weigh the potential benefits of treating a severe mental health condition against the possible, though often slight, risks associated with medication.
- Legal Action: Despite the ongoing scientific debate, some families have pursued legal action, claiming that the drug's manufacturer downplayed or failed to disclose these risks.
The Challenge of Discontinuation Syndrome
Patients attempting to stop or reduce their Lexapro dosage face another significant challenge: antidepressant discontinuation syndrome, commonly referred to as withdrawal. Unlike substance addiction, SSRI withdrawal is not based on compulsive drug-seeking behavior but rather the brain's adjustment to the sudden change in serotonin levels. Abruptly stopping Lexapro can lead to a range of uncomfortable and sometimes severe symptoms, including:
- Neurological Sensations: Dizziness, vertigo, and the distinct, electrical shock-like feeling known as 'brain zaps'.
- Gastrointestinal Issues: Nausea, vomiting, and diarrhea.
- Mood Fluctuations: Mood swings, anxiety, irritability, and rebound depression.
- Sleep Disturbances: Insomnia, vivid or disturbing dreams.
- Physical Ailments: Headaches, fatigue, and flu-like symptoms.
Experts emphasize the need for a gradual tapering process under medical supervision to minimize these effects. However, some patients experience severe and prolonged symptoms, complicating their ability to stop the medication, regardless of the tapering method.
Other Side Effects and Concerns
Beyond the more widely known controversies, Lexapro is also associated with other side effects that can impact patients' quality of life. Sexual dysfunction, including decreased libido, delayed ejaculation, and difficulty with orgasm, is a common issue with SSRIs like Lexapro and often persists throughout treatment.

The Broader Context of SSRI Effectiveness and Overprescription
Adding to the specific issues with Lexapro, a broader debate exists within the medical community regarding the efficacy of SSRIs, particularly for mild-to-moderate depression, and their high prescription rates. Some analyses of clinical trials suggest that for less severe cases, the benefits of antidepressants may not significantly outweigh those of a placebo. While highly effective for many, this has raised questions about whether they are overprescribed for conditions that might be better addressed through other therapies. The pandemic further exacerbated this concern as prescriptions surged amid increased anxiety and isolation.
Conclusion: The Patient's Perspective in the Controversy
Ultimately, the controversy with Lexapro is not a simple rejection of its therapeutic value, but rather a complex acknowledgment of its serious risks and limitations. From the FDA's stringent warnings about suicide risk and potential birth defect connections to the challenge of managing discontinuation syndrome, patients and doctors must navigate a delicate balance. The legal history of marketing misconduct adds another layer of scrutiny. The key takeaway for anyone considering or currently taking Lexapro is the necessity for open, informed communication with their healthcare provider to weigh the pros and cons in the context of their specific medical history. This enables a more empowered and safer treatment journey. For more information on navigating mental health medication, consult resources like the National Alliance on Mental Illness (NAMI).
