The Short Answer Is Yes

Yes. In Ontario you can get naltrexone for alcohol prescribed entirely online, without a referral, and you do not have to stop drinking to begin. A licensed Canadian clinician assesses you by video, prescribes naltrexone if it is a good fit, and sends it to your regular pharmacy. Naltrexone is approved by Health Canada for alcohol use disorder, and it is one of the first-line medications for it.

Maybe you are looking into this because your own drinking has been quietly bothering you and the idea of "quitting forever" feels like too big a door to walk through. Maybe you are researching it for someone you love. Either way, here is a clear, non-judgmental guide to how you actually get naltrexone in Ontario, what it costs, and why you do not have to give up drinking to start.

Can You Get Naltrexone Prescribed Online in Ontario?

Yes, and you do not need a referral from your family doctor. Naltrexone is a prescription medication, so a clinician does have to assess you first, but in Ontario that assessment can happen over a video call. If naltrexone is appropriate for you, the prescription goes to the pharmacy of your choice, and many pharmacies deliver.

This matters because the old path was slow and often discouraging. You booked a GP appointment weeks out, explained a private worry to someone who might suggest abstinence or a meeting as the only option, and hoped they knew that medication for alcohol even exists. Online prescribing removes most of that friction.

The Centre for Addiction and Mental Health notes that naltrexone is a first-line medication for alcohol use disorder, yet most people who could benefit have never been offered it. If you want to understand the medication itself first, our guide to drinking on naltrexone walks through what it feels like.

Do You Have to Stop Drinking to Start?

No. In fact, the most common way naltrexone is used for alcohol asks you to keep drinking, on purpose, while you take it. This approach is called The Sinclair Method.

You take one tablet about an hour before you drink. Naltrexone blocks the reward signal that alcohol normally sends to your brain. When you drink without that reward landing, over many repetitions your brain gradually stops chasing it. The craving softens. Drinking becomes easier to take or leave. This is why you do not white-knuckle your way through it. The medication does the neurological work in the background while you carry on with your life.

For a lot of people this is the whole reason they finally reach out. They were never going to walk into an abstinence-only program, but "keep drinking for now, and let the wanting fade" is a door they can actually open.

How Much Does Naltrexone Cost in Ontario?

There are two costs to think about: the online clinician assessment, and the medication itself. The medication is the cheaper part. Naltrexone is available as an inexpensive generic tablet, and if you qualify it is covered publicly.

Cost piece	What to expect in Ontario
Online clinician assessment	Usually private pay, and it varies by clinic and by whether ongoing support is included
Naltrexone medication	Low cost generic. Covered by the Ontario Drug Benefit under a Limited Use code if you qualify
Ongoing follow-up	Depends on the program, and on how much counselling support you want alongside the medication

On coverage: both naltrexone and acamprosate are listed on the Ontario Drug Benefit formulary with a Limited Use code, and access was expanded in 2018. If you are not covered by the Ontario Drug Benefit, the generic tablet is still one of the more affordable prescription medications you are likely to be offered. For exact pricing on our own program, the simplest thing is to ask us directly.

How Do You Actually Get Started?

The process is short and it is all remote. There are no waiting rooms and no need to explain yourself to a receptionist.

You book a confidential online assessment at a time that works for you.
You meet a Canadian physician or nurse practitioner who understands addiction medicine and The Sinclair Method.
If naltrexone is a good fit, they send the prescription to your pharmacy.
You start taking it before you drink, and you check in for follow-up so someone is walking alongside you.

That is the entire path. Most people are surprised by how undramatic it is compared to what they imagined asking for help would look like.

Is Naltrexone Safe? What Are the Side Effects?

For most people naltrexone is well tolerated, and it is not addictive. The most common side effects are nausea, headache, dizziness, and tiredness, and they often ease within the first week or two.

There are two important cautions, which is exactly why a clinician assesses you first. Naltrexone should not be combined with opioid medications, because it blocks them and can trigger withdrawal. And because it is processed by the liver, your clinician will consider your liver health before prescribing. This is a normal part of the assessment, not a reason to be alarmed.

If naltrexone is not the right fit for you, it is not the only option. Acamprosate is another medication approved in Canada, and our guide to acamprosate in Canada explains how it differs.

How Is This Different From Rehab or Quitting for Good?

This is a treatment built for people who want to change their drinking without necessarily quitting it forever. Rehab and abstinence-based programs ask you to stop, fully, from the start. That works for some people. For many others, it is the reason they never get help at all, because they are not ready to define themselves as someone who can never drink again.

The naltrexone approach meets you where you are. Your goal might be to drink much less. It might be to reset your relationship with alcohol and see where you land. It might, over time, become abstinence, and that is allowed too. You do not have to decide the ending before you start.

If you are reading this for someone you love, the same logic holds. You cannot make someone ready, but you can understand the options, so that when they are ready you can point them somewhere that will not shame them for wanting a middle path. If you are still working out whether your own pattern even counts, our post on grey area drinking is a gentle place to start.
