Woman Hospitalised After Taking Illegal Weight Loss Drug

A woman in Brazil has been diagnosed with a rare and potentially life-threatening illness after taking an unauthorised weight loss drug from Paraguay. Kellen Oliveira Bretas Antunes, 42, was rushed to hospital on December 17, 2022, experiencing severe abdominal pain linked to the illegal weight loss pen.

The administrative assistant from Minas Gerais was discharged on Christmas Day, but her condition deteriorated rapidly. Just days later, she was readmitted with neurological complications, ultimately diagnosed with Guillain-Barré Syndrome (GBS). This rare condition occurs when the immune system mistakenly attacks the peripheral nerves, leading to symptoms such as muscle weakness, numbness, and, in severe cases, respiratory failure.

During her second hospitalisation, Ms Antunes exhibited additional symptoms including dark urine and respiratory distress. After an initial improvement, her stepdaughter reported that she is now stable and undergoing treatment aimed at slowing the progression of GBS. “There has been a significant improvement,” the stepdaughter stated. “But the process will be long. Since she was diagnosed with Guillain-Barré Syndrome, it will take at least 12 months of treatment, including physiotherapy and speech therapy.”

The weight loss pen that Ms Antunes took has raised significant health concerns. Her family attempted to have the vial analysed at João XXIII Hospital, but officials were unable to test it due to its origin from Paraguay. “Initially, she was hospitalized with severe abdominal pain, and drug poisoning was confirmed,” her stepdaughter added.

Following the incident, Brazil’s National Health Surveillance Agency (Anvisa) issued a public warning regarding the dangers of purchasing unregulated weight loss products. Anvisa highlighted that many slimming pens are not licensed for sale in Brazil, making them potentially dangerous due to unknown ingredients and lack of regulation.

According to endocrinologist Márcio Lauria, the risks associated with unauthorised medications are substantial. “Every time you ingest a medication whose origin you don’t know, it could contain anything,” he explained. “These products might not go through the necessary safety and efficacy checks before being sold.”

The case of Kellen Oliveira Bretas Antunes serves as a stark reminder of the potential hazards associated with illegal weight loss drugs and the importance of seeking medical guidance before using such products. As her family navigates the long road to recovery, they hope that her experience will encourage others to avoid unregulated treatments.
