Prescribed and over the counter
Codeine is an opioid, and dependence can build even when a doctor prescribed it. How to come off safely, and where the free help is.
Codeine is an opioid, and both codeine and co-codamol can cause dependence even when a doctor prescribed them and you took them exactly as told. The way off is a gradual reduction planned with a GP, not willpower and not stopping overnight. Withdrawal is thoroughly unpleasant, but unlike alcohol or diazepam it is not generally life threatening. The real danger comes afterwards, and almost nobody mentions it.
If you have been searching this at two in the morning and landing on forum threads, that is because straight answers are scarce. Here is one.

The NHS gives a plain test for this, and it is shorter than you might expect. If you are addicted to the codeine in co-codamol, you may find it difficult to stop taking it, or feel you need to take it more often than necessary. That is the whole of it. No score, no questionnaire.
The over-the-counter packets carry their own warning on the front, in the plainest English the regulator could manage: can cause addiction, for three days use only. Most people who end up dependent were not being reckless. They had a bad back, or a surgery, or a migraine that would not lift, and three days turned into three months.
You do not have to settle on a word for it before you are allowed help. Nobody at a GP surgery, on a support line or in a meeting is going to make you call yourself an addict first.
This is where the internet does real harm, so here is the careful version. UK clinical guidance does not support the claim that opioid withdrawal kills. Alcohol and benzodiazepines such as diazepam genuinely can be dangerous to stop abruptly. Codeine is a different thing: withdrawal is miserable and self-limiting.
The NHS lists what to expect if you stop suddenly: feeling agitated or anxious, panic attacks, a pounding heartbeat, trouble sleeping, shaking, sweating, body aches and restlessness. Flu crossed with dread, is how people tend to describe it.
So the advice not to stop suddenly is real, and the NHS gives it, but the reason is comfort and success rather than mortal danger. People who go cold turkey alone are simply far likelier to be back on it by Thursday. Being frightened into silence helps nobody, which is why it is worth saying this plainly.
Losing your tolerance and then going back to your old dose. It is the thing that kills people, and it happens after the hard part, which is what makes it so cruel.
A few days or weeks off opioids and your body's tolerance falls quickly. The dose that was ordinary a fortnight ago can stop your breathing. This is why UK guidance requires that people coming off opioids have it explained to them, and why a bad week is a reason to ring your GP rather than to quietly resume where you left off.
If you are ever with someone who has taken an opioid and cannot be roused, or whose breathing has gone slow or noisy, call 999. That is an emergency and it is treatable.
This one gets missed, and for anyone taking a lot of tablets it can be the more urgent problem. Co-codamol comes in three strengths, 8mg, 15mg or 30mg of codeine, and every one of them carries 500mg of paracetamol in each tablet, the same as a standard paracetamol tablet.
The NHS maximum is eight co-codamol tablets in 24 hours. Its warning is blunt: taking too much can be very dangerous, because the paracetamol in it can cause liver damage. Somebody chasing the codeine can pass a dangerous amount of paracetamol long before they feel anything is wrong, and liver damage is quiet until it is not.
If you are already taking more than eight a day, that is worth a same-week conversation with a pharmacist or GP, ahead of any plan about stopping. Say the number out loud. They have heard it before and they are not there to tell you off.
With a doctor, gradually. The NHS is specific: do not stop taking codeine suddenly, and your doctor will reduce your dose gradually over several weeks or months. Weeks or months, not days, and that is normal rather than a sign anything has gone wrong.
This page will not give you a tapering schedule, and you should be wary of any page that does, because the right steps depend on your dose, how long you have taken it, what else you take and what the pain was for in the first place.
If the appointment itself is the obstacle, it often helps to have the sentence ready. Something like: I have been taking co-codamol for longer than I meant to, I think I am dependent on it, and I would like help to come off. That is enough. Dependence on a prescribed medicine is an ordinary part of a GP's week, you have done nothing wrong by developing it, and asking does not put a flag on your record that follows you around.
Your GP first, for the reduction itself. Your local drug and alcohol service is free too and in most areas takes self-referrals, so you do not need anyone's permission to contact them, and yes, they are for prescribed medicines as well as illegal ones.
Postscript360 is worth knowing about and hardly anyone does. It is a charity support line on 0117 966 3629 that works specifically with prescribed and over-the-counter medicines, including painkillers, benzodiazepines, Z drugs and gabapentinoids. Someone there will have spoken to a hundred people in your position.
And meetings, which cost nothing and need no referral. More on whether they are for you below.
This is the question people actually want answered, and the honest reply is that it depends on the room, so here is what each fellowship publishes rather than a recommendation from us.
Cocaine Anonymous has the plainest written welcome: its only requirement for membership is a desire to stop using cocaine and all other mind-altering substances, and there are no dues or fees. Plenty of people there never touched cocaine. SMART Recovery is explicitly neutral about medication, treats what you take as a matter between you and your doctor, and asks nobody to label themselves. Narcotics Anonymous is the biggest network by far and many people on prescribed medication are welcomed warmly, though its literature leaves some room for individual groups to take their own line, so experiences differ between rooms rather than being uniform.
Two things hold across all of them. No fellowship gives medical advice, and nobody should change or stop a prescribed medicine because of something said in a meeting. If a room does not suit, that is information about the room, not a verdict on you, and there are thousands of others including online ones you can sit in on with the camera off.
You can search every UK meeting here by postcode or town. It is free, there is no sign-up, and we do not sell treatment or take a penny for sending anyone anywhere.
Yes. The NHS says it is possible to become addicted to the codeine in co-codamol, which is why doses get reviewed. The plain signs it gives are finding it difficult to stop, or feeling you need to take it more often than necessary. It can happen to people who took it exactly as prescribed.
Stopping suddenly causes real withdrawal, including agitation, anxiety, panic attacks, palpitations, sleeplessness, shaking, sweating and body aches, and the NHS advises against it. Unlike alcohol or diazepam withdrawal, opioid withdrawal is not generally life threatening, but a gradual reduction planned with a doctor is far more likely to work.
Losing tolerance and then returning to your old dose. After even a short break the amount you used to take can suppress your breathing. This is why UK guidance requires it to be explained, and why a difficult week is a reason to phone your GP rather than quietly restart at the old dose.
The NHS says a doctor will reduce your dose gradually over several weeks or months. There is no single timetable, because it depends on your dose, how long you have taken it and what else you take. A slower reduction is not a failure, it is usually what makes it work.
It can be the more urgent one. Every strength of co-codamol contains 500mg of paracetamol per tablet, and the NHS maximum is eight tablets in 24 hours. Taking more can cause liver damage, often with no warning symptoms, so tell a pharmacist or GP the real number you are taking.
Yes, and many people there did. Cocaine Anonymous asks only for a desire to stop using mind-altering substances, and SMART Recovery is explicitly neutral about prescribed medication. No fellowship gives medical advice, and nobody should change a prescribed medicine because of anything said in a meeting.
Postscript360 runs a support line on 0117 966 3629 that works specifically with prescribed and over-the-counter medicines, including painkillers, benzodiazepines and gabapentinoids.
