Introduction
In 2025, the number of pharmaceutical drug lawsuits continues to rise across the United States. Many prescription medications, once believed to be safe, are now linked to severe health complications such as organ damage, cancer, and hormonal disorders.
Just like the ongoing Depo-Provera lawsuit, several other drugs have faced similar legal action due to their hidden risks and lack of transparency.
In this article, Legal Claim Counsel highlights the top 10 dangerous drugs linked to lawsuits in 2025, their major side effects, and how victims can take legal action to pursue justice.
1. Ozempic and Wegovy (Semaglutide)
Originally designed to manage Type 2 diabetes, Ozempic and Wegovy became extremely popular for weight loss. However, users have reported severe stomach paralysis (gastroparesis), intestinal blockage, and chronic vomiting.
Lawsuits allege that Novo Nordisk failed to properly warn users about these serious gastrointestinal risks.
- Main Allegation: Failure to warn and gastrointestinal injuries.
- Manufacturer: Novo Nordisk.
2. Depo-Provera (Medroxyprogesterone Acetate)
Depo-Provera, a hormonal birth control injection, has been associated with bone density loss, mood changes, weight gain, and brain tumors (meningioma).
