Government expands chemical suppressant pilot for sex offenders

Hundreds more sex offenders will be given access to chemical suppressant medication under an expanded Ministry of Justice pilot aimed at cutting reoffending and protecting the public.

The scheme, initially piloted in four prisons in the South West, will now extend to the North West and North East of England, covering around 20 prisons in total. The expansion means approximately 6,400 offenders will be eligible for medication alongside psychological treatment.

How the medication works

The drugs include selective serotonin reuptake inhibitors (SSRIs), which reduce intrusive sexual thoughts, and anti-androgens, which lower testosterone and suppress libido. When combined with therapy and coordinated support, these treatments are designed to reduce the risk of reoffending, including crimes such as assault, grooming and rape.

Deputy Prime Minister’s comments

Deputy Prime Minister David Lammy said:

“Protecting the public is my priority. Evidence shows this medication helps suppress urges, which is why we’re expanding access to it.

This part of our comprehensive approach to managing dangerous offenders and preventing reoffending. Every tool we deploy serves one main purpose: keeping communities safe and reducing the number of victims.

Make no mistake – those who commit serious crimes will face the full force of the law. But alongside prison, we have a duty to use every method available to rehabilitate offenders and protect the public, as part of our Plan for Change.”
