No. Paracetamol on its own is not an addictive drug. It produces no high, no craving, no escalating tolerance and no withdrawal syndrome, and no UK regulator treats it as a medicine people become dependent on.
That answer alone is close to useless. Almost nobody asks can you get addicted to paracetamol out of curiosity. Three real things sit behind the question. One of them is a recognised diagnosis with paracetamol’s name written into it. Another is that the tablet in your hand may not be paracetamol alone.
Start with what is actually in the packet
Co-codamol, as the NHS describes it, is a mixture of two different painkillers, paracetamol and codeine. Codeine is an opioid. Paracetamol is not. The NHS is direct about which half carries the risk: “It’s possible to become addicted to the codeine in co-codamol”, and describes what that looks like from the inside: finding “it difficult to stop taking it or feel you need to take it more often than necessary”.
In 2009 the MHRA introduced tighter controls on over-the-counter medicines containing codeine or dihydrocodeine, explicitly “to minimise the risk of overuse and addiction to these medicines”, including a warning that must appear prominently on the front of the pack beginning with the words “Can cause addiction”. We do not print the rest of that warning, because this page publishes no limits. The leaflet must carry the warning signs too: needing the medicine for longer periods and in higher amounts than recommended, and stopping making you feel unwell while restarting makes you feel better.
A 2013 review of over-the-counter medicine abuse found five groups of products implicated internationally, and codeine-based compound analgesics headed the list. Paracetamol alone is not among the five. Our observation is that paracetamol is the ingredient people name, and codeine is the one doing the work.
If codeine, co-codamol, co-dydramol or tramadol is the real question, prescription drug addiction and opioid withdrawal are the pages you want, and there the answer is genuinely yes.
Why plain paracetamol does not meet the definition
Four checks point the same way, and one complicates the picture.
The NHS page on paracetamol for adults, last reviewed on 24 March 2026, does not use the words addiction, dependence, habit or withdrawal anywhere. Its only use of the word dependence concerns alcohol, listed among the reasons paracetamol may not suit someone.
Its licensed product information contains no section on abuse, dependence, tolerance or withdrawal at all. We read section 4.4 in full: its warnings concern children, kidney and liver impairment, alcoholic liver disease, and not doubling up on paracetamol-containing products. Nothing else.
Paracetamol does not appear on the Home Office list of drugs controlled under the misuse of drugs legislation. Codeine and dihydrocodeine do.
And NICE NG215, the UK guideline written specifically about medicines associated with dependence or withdrawal symptoms, covers opioids, benzodiazepines, gabapentinoids, Z-drugs and antidepressants. Paracetamol is not in its scope.
The complication is why the question is not a silly one. Paracetamol’s own product information says “its mechanism of action is not fully understood”, and that it is thought to act predominantly in the central nervous system. Our reading is that a centrally acting drug whose mechanism is still open is a fair thing to wonder about, and that the absence of dependence is a finding from decades of surveillance rather than a deduction.
The diagnosis with paracetamol’s name in it
The International Classification of Headache Disorders contains a code, 8.2.3.1, called paracetamol (acetaminophen)-overuse headache.
Medication overuse headache is where painkillers taken for headache begin to sustain it. The classification calls it “an interaction between a therapeutic agent used excessively and a susceptible patient”, which our reading is a careful way of saying it is neither a property of the drug nor a flaw in the person. It “usually, but not invariably, resolves after the overuse is stopped”.
NICE CG150 asks clinicians to be alert to it in people whose headache developed or worsened while they were taking, for three months or more, paracetamol, aspirin or an anti-inflammatory, alone or in any combination. The guideline names paracetamol directly.
Two details make this feel like addiction when it is not. NICE tells clinicians to warn people that when the overused medication is withdrawn, “headache symptoms are likely to get worse in the short term before they improve and that there may be associated withdrawal symptoms”. And the classification notes that the behaviour of some people with medication overuse headache resembles that seen in drug addiction, and that scores on the Severity of Dependence Scale, an instrument built for addiction research, predict medication overuse among headache patients.
So a real cycle exists, it has a name, and paracetamol can be the medicine sustaining it. It is still not addiction, and the route out is not one to attempt alone. NICE reserves specialist referral for people using strong opioids, and says inpatient withdrawal should not routinely be offered, which our reading is a reassurance rather than a restriction.
We have deliberately not printed the day counts that define overuse in either document. The classification itself says those numbers “are based on expert opinion rather than on formal evidence”, and a threshold here would mostly work as a line readers could sit under and stop worrying. If you take painkillers for headache often enough to have counted, that is the conversation to have with a GP. Our page on naproxen sets out the diagnostic criteria in full, framed as what a clinician uses to recognise the pattern rather than as a limit to stay under.
Habit, dependence and addiction are three different words
The NHS defines addiction broadly: “not having control over doing, taking or using something to the point where it could be harmful to you”, and it applies that definition to work, shopping and the internet as readily as to drugs. On the NHS’s own wording, a substance’s pharmacology is not what decides the question. Loss of control and harm are.
That cuts both ways. Paracetamol is not an addictive drug in the pharmacological sense, and stopping it produces no withdrawal. It also means that if you cannot stop reaching for it, if you carry it everywhere, if you take it pre-emptively for a pain that has not arrived, something is going on that a flat no does not address. That something is usually untreated pain, anxiety about pain, or the headache cycle above. None is a moral failure, and all three have better answers than another box of tablets.
We are not going to give you a checklist. Any question we could offer has a version you could pass and stop asking.
The question sitting next to this one
Some people arrive here having already searched something heavier.
Paracetamol self-poisoning is common enough in the UK that Parliament legislated, restricting over-the-counter pack sizes in 1998. The long term evaluation published in the BMJ in 2013 estimated a 43% reduction in deaths involving paracetamol alone that received suicide or undetermined verdicts, roughly 765 fewer deaths over the eleven years that followed, and a 61% fall in registrations for liver transplantation. The inconvenient parts of the same paper: actual transplantations did not fall significantly, non-fatal hospital presentations did not decline, and the authors concluded that “the continuing toll of deaths suggests, however, that further preventive measures should be sought”.
The detail worth carrying away comes from the same group’s account of why the law changed. People interviewed after paracetamol overdoses often described the act as impulsive, using medicine already in the house. Impulsive is the word that matters. The gap between the thought and the act can be very short, and anything that widens it helps.
If you have taken more paracetamol than the packet says, get help now, even if you feel completely well. NHS advice is to call 111 or use 111 online, and if you are told to go to A&E, not to drive there. Feeling fine proves nothing. If someone is unresponsive or seriously unwell, call 999. Outside the UK, use your local emergency number. If it is thoughts of ending your life rather than tablets, the Samaritans are free on 116 123, and the NHS names them for this.
Talking to us
The Orchid Recovery is a private residential addiction and mental health centre in Hang Dong District, Chiang Mai, Thailand, for international English speaking adults, capped at 20 clients.
If your answer turned out to be paracetamol, the useful next step is a GP appointment about why the pain or the headaches have not resolved, and that is a better outcome than anything we sell. If it turned out to be the codeine in the same box, that is what we treat. Our prescription drug and opioid programmes open with supervised detox where it is clinically needed, our clinical team is listed here, and where pain and low mood are tangled together we treat both sides through dual diagnosis care. You can speak to us either way.

Frequently Asked Questions
Can you get addicted to paracetamol?
Not in the pharmacological sense. Paracetamol produces no high, no craving, no escalating tolerance and no withdrawal syndrome, its UK product information contains no section on abuse or dependence, and it is not a controlled drug. If you cannot stop taking it, that is worth raising with a GP, but the explanation will be something other than addiction to the drug itself.
Is paracetamol a controlled drug?
No. It does not appear on the Home Office list of drugs controlled under the misuse of drugs legislation, and it can be bought without a prescription in the UK. Codeine and dihydrocodeine do appear on that list, which is why the combination products containing them are treated differently from paracetamol on its own.
Can paracetamol cause withdrawal symptoms?
Paracetamol has no withdrawal syndrome of its own. NICE does warn that when someone with medication overuse headache stops the overused painkiller, symptoms are likely to worsen in the short term and there may be associated withdrawal symptoms. That is the headache cycle unwinding rather than physical dependence on paracetamol, and it is something to plan with a GP.
Am I addicted to co-codamol rather than paracetamol?
Possibly, and it is a common mix-up. Co-codamol contains paracetamol and codeine, and the NHS states plainly that you can become addicted to the codeine in it. The signs it gives are finding it difficult to stop, or feeling you need it more often than necessary. Tell a GP the real number of tablets, and do not stop an opioid abruptly on your own.
Why do I get a headache when I stop taking paracetamol?
If you take painkillers for headache frequently, the painkillers can begin to sustain the headache. This is medication overuse headache, a recognised diagnosis that includes a specific code for paracetamol. It usually, though not always, resolves once the overuse stops. It is not addiction, and it needs a GP rather than a decision made alone.
Is it safe to take paracetamol every day?
That is a question for a pharmacist or GP rather than an article, because the answer depends on your liver, your drinking, what else you take and why the pain is still there. What we can say is that taking it daily for months is a reason to be seen, and that the reason is not addiction risk.
I have taken too much paracetamol. What should I do?
Get medical help immediately, even if you feel completely well, because early paracetamol harm can be silent and treatment works best when it starts early. NHS advice is to call 111 or use 111 online if you have taken more than the packet says. If someone is unresponsive, call 999. Outside the UK, use your local emergency number.
What happens if I ask about treatment and it turns out I do not need it?
We say so. An enquiry is a conversation rather than an application: someone asks what you take, why, for how long and what has already been tried, and the answer at the end can be that a GP is the right person and we are not. Nothing is booked during that call. Start one on +66 985 245 093 or at admissions@orchidrecoverythailand.com.
