Dihydrocodeine Withdrawal

Reviewed by Michael Williams, Treatment Manager, Abbington House

If you’ve been taking dihydrocodeine regularly and you’re wondering what happens when you stop, or if you’ve already started to feel something changing between doses, this page explains what withdrawal involves, what the symptoms are and how long they typically last. 

Dihydrocodeine is an opioid, so even when taken as prescribed, regular use can lead to physical dependency. Withdrawal is what happens when the body begins adjusting to functioning without it. It is uncomfortable, sometimes significantly so, but it follows a pattern and it does pass.

What Dihydrocodeine Withdrawal Feels Like

Withdrawal begins when the drug starts to leave the body. What you might feel first is usually restlessness, anxiety and an uneasy feeling that’s hard to place, not necessarily panic, but an agitation that doesn’t settle.

Towards the end of the first day, physical symptoms become more noticeable. These commonly include muscle aches, sweating, chills, a runny nose, watering eyes and difficulty sleeping. Nausea, stomach cramps and diarrhoea often follow. Cravings for the drug can be intense because your body is telling you the quickest way to stop feeling like this is to take another dose.

None of this means something is going wrong, but that your body is recalibrating after a period of dependency. while it’s unpleasant, it’s not typically dangerous in itself, the main medical risk is dehydration from vomiting or diarrhoea, which is why medical support matters.

How Long It Lasts

Everyone’s experience is different, and the timeline depends on how much you’ve been taking, how long you’ve been taking it, and your individual physiology. But the general shape is consistent.

The first symptoms usually appear within 8 to 24 hours after the last dose. The most intense physical symptoms tend to peak around days two to three. By the end of the first week, the worst of the physical discomfort is usually easing. Most acute symptoms have resolved within 7 to 14 days.

What can take longer is the psychological aftermath. Mood swings, low energy, anxiety, irritability, and disturbed sleep can continue for weeks or sometimes months after the physical withdrawal has passed. This is sometimes called post-acute withdrawal, and it’s common with opioid dependency. It doesn’t mean recovery isn’t working; the brain is still taking time to adjust. It does improve, but it takes time, and it’s one of the reasons ongoing support matters.

Why Stopping Suddenly Isn’t Recommended

If you’ve been taking dihydrocodeine regularly, stopping abruptly is likely to produce more severe withdrawal symptoms than a managed reduction. The NHS advises that doctors should reduce the dose gradually when stopping opioid treatment, and the manufacturer’s guidance for DHC Continus states clearly that the medication should not be stopped suddenly.

A gradual taper, supervised by a GP or within a clinical setting, gives the body time to adjust in stages rather than all at once. This doesn’t eliminate withdrawal entirely, but it reduces its intensity and makes the process more manageable.

For people whose use has escalated significantly, or who are obtaining dihydrocodeine from sources other than a single prescription, a managed detox with medical supervision may be more appropriate than a GP-managed taper at home.

What Comes After Withdrawal

Clearing the drug from the body is necessary but it doesn’t address why the dependency developed, what the drug was managing beyond pain, or how to live without it long-term. The early weeks after acute withdrawal can feel flat, and while the physical symptoms pass, motivation, sleep and mood can take time to stabilise. That gap is where support matters most, and where many people find that withdrawal alone isn’t enough to sustain the change.
