Renowned children’s author Sally Gardner has revealed a deeply personal battle with compulsive shopping, attributing it to prescription drugs prescribed for her Restless Legs Syndrome.

Compulsive Spending and Financial Loss

Gardner, who has sold 2.5 million books and won the Carnegie Medal, found herself spiraling into reckless spending, exceeding £500,000. Initially, she believed her ability to purchase luxury items – including a £3,000 bathtub and artwork – was due to her financial success.

A Cycle of Secrecy and Debt

The spending quickly became uncontrollable, leading to secrecy and mounting debts. Gardner was eventually forced to downsize from her north London townhouse to a smaller apartment. She described feeling dissociated and questioning her identity as her spending escalated.

The Role of Dopamine Agonist Medications

For years, the cause of Gardner’s compulsive behavior remained unknown. She was unaware that the dopamine agonist drugs prescribed for her Restless Legs Syndrome could have such a detrimental side effect.

Understanding Dopamine and Impulsive Behavior

Dopamine agonist drugs, used to treat conditions like Parkinson’s disease and Restless Legs Syndrome, increase dopamine levels in the brain. However, growing evidence links them to impulsive behaviors like compulsive shopping, gambling, and hypersexuality.

Gardner confessed to repeatedly purchasing the same items, driven by a dopamine rush – including five identical pairs of shoes and ten dog beds for her Yorkshire Terrier. She described the addictive nature of this dopamine hit.

Growing Concerns and Regulatory Review

Gardner’s experience is not isolated. The BBC has highlighted numerous similar cases, with patients and families detailing the devastating consequences of these drug-induced compulsions. Many didn’t connect their behavioral changes to the medication until significant damage was done.

The UK’s Medicines and Healthcare products Regulatory Agency is now reviewing this critical issue.

Similar Cases Highlight the Risks

Gardner discovered the potential link after listening to a BBC podcast, realizing her life had been “hijacked” by the medication. She continues to take the drugs, as they remain the only effective treatment for her Restless Legs Syndrome, but still battles urges daily.

This mirrors the case of Jane Ryde, whose husband, a Parkinson’s sufferer, became a “sex addict” after being prescribed Pramipexole, with minimal warning about potential side effects. Ryde stated her husband would have been horrified by the drug’s impact.

These stories underscore the urgent need for increased awareness and clearer warnings regarding the potential side effects of dopamine agonist drugs.
