Is Naltrexone Available in the UK and Ireland? What You Need to Know

Key Takeaways

• Naltrexone is a prescription-only medication in both the UK and Ireland.

• Access typically requires a consultation with an addiction specialist.

• NHS services tend to favour abstinence-only treatment models.

• The Sinclair Method requires private support and prescription.

• A 1-2-1 reduction programme significantly boosts success rates.

What Is Naltrexone and How Does It Work?

Naltrexone is a non-addictive opioid antagonist that blocks the brain’s ability to feel pleasure from alcohol. Over time, drinking becomes less rewarding, reducing cravings and consumption naturally — a process known as Pharmacological Extinction.

This effect is the foundation of The Sinclair Method (TSM), where individuals take Naltrexone only prior to drinking, gradually reprogramming their brain’s response to alcohol.

Can You Get Naltrexone in the UK?

Yes — but with important caveats.

• Naltrexone is licensed and available in the UK for alcohol dependence.

• It's primarily prescribed after someone has quit drinking and wants help staying sober.

• The NHS typically follows an abstinence-based model, making it difficult to access Naltrexone for controlled drinking approaches like TSM.

• To use Naltrexone with The Sinclair Method, you'll likely need to go through private addiction services.

• A prescription from a private addiction specialist is usually required.

• It's essential to combine medication with individualised 1-2-1 reduction support, as found in programmes like ours.

What About Access in Ireland?

In Ireland, Naltrexone is available under the brand name Nalorex, approved for use since 2001.

• As in the UK, it is a prescription-only medicine.

• It is often prescribed through addiction treatment services, with a strong lean towards abstinence.

• People seeking to reduce drinking through TSM will likely need to access private healthcare providers or online services offering specialist coaching and prescriptions.
