Naltrexone is a prescription medication used in the Sinclair Method to reduce problem drinking. In the UK, it is rarely prescribed on the NHS for this indication, so almost all patients pay privately. There are two costs to think about: the medication itself, and the clinical service that gets you the prescription.
The medication
A pack of 28 naltrexone 50mg tablets retails between £85 and £100 from UK private pharmacies in 2026. The exact price varies by pharmacy, brand, and supply availability.
At LoveMyLife the in-house pharmacy charges £99 per pack retail, or £79 per pack at member rate on the Programme and Ongoing tiers.
How long a pack lasts depends entirely on how often you drink. The protocol is one tablet per drinking occasion, so a regular daily drinker uses about a pack a month, while someone who drinks two or three days a week uses a pack every six to eight weeks.
The clinical service
The UK private market structures naltrexone care in a few different ways. Fixed-price programmes typically run £500-£800 for a 90-day to 5-month package. Monthly subscriptions with medication bundled usually sit around £200 per month with a three-month minimum. Coaching-led packages sit in a similar range. The service fee pays for the clinical oversight; medication is usually charged separately, except in the subscription model.
LoveMyLife offers four tiers, starting at £99 for a form-reviewed prescription through the online pharmacy and going up to £499 for the 90-day Programme with structured support and doctor oversight. Medication is charged separately at the rates above. Full detail on each tier is on the Sinclair Method pricing page.
Total typical cost for a 90-day programme
Across the UK private market, a 90-day naltrexone treatment programme including medication usually works out between £600 and £900, depending on whether the clinical package is subscription-based, fixed-fee, or coaching-led. Consultant-led boutique programmes can run significantly higher.
At LoveMyLife:
Direct tier (£99) plus one pack of medication: around £198 for the first pack.
Programme (£499) plus three packs at member rate (3 × £79 = £237): around £736 for the full 90-day treatment including medication.
What about the cost of bloods?
Most providers recommend a baseline liver function test (LFT). At LoveMyLife the LFT is £49 via our own lab, or you can bring a recent NHS LFT for free. Private LFTs elsewhere typically cost £49-£73.
Some providers, including LoveMyLife, allow patients to start without an LFT initially if their drinking history is low-risk. This is a clinician call made at assessment.
