Colchicine
In brief
- In our pharmacy, you can buy colchicine without a prescription, with discreet delivery across the United Kingdom. In many countries it is still prescription-only, but availability may vary by local regulations.
- Colchicine is used to treat and prevent gout attacks, and it is also used for familial Mediterranean fever. It works by reducing inflammation, particularly by inhibiting neutrophil activity and the inflammatory response to urate crystals.
- The usual dose of colchicine depends on the condition: for an acute gout flare, 1.2 mg at the first sign followed by 0.6 mg one hour later; for prevention, 0.6 mg once or twice daily; for familial Mediterranean fever, usually 1.2–2.4 mg per day in divided doses.
- The form of administration is oral, usually as tablets; oral solution is rare.
- It usually starts working within about 1 to 2 hours, especially for acute gout symptoms.
- The duration of action is several hours, while preventive use may continue daily for weeks, months, or longer as directed by a clinician.
- Alcohol should be avoided or kept to a minimum, as it may worsen gout and can increase stomach irritation and dehydration.
- The most common side effects are diarrhoea, nausea, abdominal pain, and vomiting.

Colchicine In The United Kingdom: What Patients Need To Know
Critical Warnings, Patient Safety, And Who Should Avoid It
Thinking about colchicine for a gout flare or prevention?
The most important safety issue is who should not take it, or should only take it with specialist advice.
People with severe kidney or liver impairment should generally avoid colchicine because the medicine can build up and become toxic.
Do not use it if you have a known allergy to colchicine or any excipient.
It must also be avoided with strong CYP3A4 inhibitors or P-gp inhibitors, because that interaction can drive dangerous, sometimes life-threatening toxicity.
Extra caution is needed in older adults, people with kidney or liver disease, those with gastrointestinal disease, and during pregnancy or breastfeeding.
Seek urgent advice if you have any of the following:
- Severe vomiting or diarrhoea.
- Muscle weakness or muscle pain.
- Unusual bruising or bleeding.
- Numbness, fever, or confusion.
- Reduced urine, palpitations, or collapse.
An overdose can be fatal, so emergency help is needed immediately if too much has been taken or a child has swallowed the tablets.
Activities, Driving, And Workplace Safety
Colchicine can cause diarrhoea, dizziness, fatigue, and weakness, all of which can affect concentration and reaction time.
In UK practice, the advice is straightforward: do not drive or operate machinery if you feel affected.
If your job involves safety-critical work, follow your employer’s safety procedures and tell a supervisor if you are unwell.
Can I Drive After Taking Colchicine In The UK?
Only if you feel well and are not affected by side effects.
If diarrhoea, dizziness, weakness, or fatigue makes you less alert, stop driving and seek advice.
What Colchicine Is And UK Brand Names
Colchicine is the International Nonproprietary Name, or INN, for this medicine.
Its ATC code is M04AC01, which sits under antigout preparations.
That classification matters because it tells clinicians that colchicine is used in gout-related care but does not work by lowering uric acid.
- INN
- The standard international medicine name: colchicine.
- ATC Code
- M04AC01, used for colchicine mono-preparations.
- Prescription-Only Medicine
- A medicine supplied only on a valid prescription in the UK.
- Gout Prophylaxis
- Regular use to help prevent gout flares.
In the UK, colchicine is supplied under MHRA oversight as a prescription-only medicine.
Common regional examples include Colchicine Opocalcium, Colchimax, and Colchicine 1A Pharma.
Most products are tablets in blister packs, typically 0.5 mg or 1 mg, although oral solution is rare.
If you are searching for Colchicine tablets UK, Colchicine 500 microgram tablets, or Colchicine prescription UK, these are the strengths and access routes most people are referring to.
How Colchicine Works In The Body
People often ask why colchicine helps so quickly with gout pain.
It works by reducing inflammation, mainly by affecting how white blood cells move and how inflammatory signals are passed on.
In plain terms, it helps calm the inflammatory cascade that drives a flare.
Clinical Explanation
Colchicine is used in gout and familial Mediterranean fever, or FMF.
It does not lower uric acid, so it is not a urate-lowering treatment.
What it does:
- Reduces inflammation.
- Helps during an acute gout flare.
- Can be used to prevent recurrent gout flares.
- Has an established role in FMF.
What it does not do:
- It does not dissolve urate crystals.
- It does not lower serum uric acid.
- It does not replace allopurinol or febuxostat for long-term urate control.
That is why M04AC01 is described as preparations with no effect on uric acid metabolism.
UK-Approved Uses And Common Off-Label Use
In UK-aligned practice, colchicine is used for acute gout flare treatment, gout flare prevention, and FMF.
In many countries, including specialist settings, it may also be used off-label for pericarditis.
When someone has repeated flare-ups, clinicians may choose colchicine because it provides anti-inflammatory support without being an NSAID.
It is also considered when prevention is needed while other gout medicines are being introduced.
| Condition | Typical Role | On-Label Or Off-Label |
|---|---|---|
| Acute gout flare | Short-course flare treatment | On-label |
| Gout flare prevention | Daily prophylaxis | On-label |
| Familial Mediterranean Fever | Long-term control | On-label |
| Pericarditis | Specialist anti-inflammatory support | Off-label in many countries |
Cardiovascular studies exist, but this should not be treated as a routine self-care use.
Standard Dosing For Adults And Children
Patients often worry that the dose changes depending on the reason for treatment, and that is exactly right.
Colchicine has a narrow safety margin, so the dose must match the indication.
| Indication | Typical Dose | Key Point |
|---|---|---|
| Acute gout flare | 1.2 mg at first sign, then 0.6 mg one hour later; max 1.8 mg/day | Do not repeat within 3 days |
| Gout prevention | 0.6 mg once or twice daily | Used continuously and reviewed later |
| FMF | 1.2–2.4 mg/day in divided doses | Often long term |
| Pericarditis | 0.5–0.6 mg once or twice daily with NSAIDs | Specialist use |
Dose adjustments to remember:
- Use a lower starting dose in older adults.
- Reduce the dose in renal impairment or hepatic impairment.
- Avoid use in severe renal or hepatic impairment unless a specialist specifically advises otherwise.
- In children, colchicine is generally for FMF only, from about 4 years of age, starting at 0.3–0.6 mg/day and titrating.
What If I Miss A Dose?
Take it when remembered unless the next dose is near.
Do not double up.
How Long To Take It And When To Review
For an acute gout flare, colchicine is usually taken as a single or split dose on day 1.
It should not be repeated within 3 days.
For prevention, it may be used daily and then reviewed at 3 to 6 months.
For FMF, treatment is often long term or lifelong under specialist advice.
Review is important if symptoms are not settling or if side effects start to appear.
Review sooner if you have:
- Poor symptom response.
- Diarrhoea or vomiting.
- Muscle pain or weakness.
- Rash.
- Recurrent flares despite treatment.
Renal and liver function monitoring may be needed where relevant.
Side Effects And When To Seek Help
The commonest side effects are digestive ones, which often show up early.
Mild effects include diarrhoea, nausea, abdominal pain, and vomiting.
More troublesome effects can include fatigue, muscle pain, rash, and, rarely, blood count changes.
Persistent gut symptoms should never be ignored, because they can be an early sign of toxicity.
Get urgent help if you notice:
- Severe weakness.
- Reduced urine.
- Confusion.
- Palpitations.
- Bleeding, bruising, or collapse.
Is Diarrhoea Normal On Colchicine?
Yes, diarrhoea is common.
But if it is persistent or severe, you need prompt advice because it may mean the dose is too high or toxicity is developing.
Interactions With Medicines, Food, And Alcohol
This is the part of colchicine prescribing that most often catches people out.
Strong CYP3A4 inhibitors and P-gp inhibitors can raise colchicine levels sharply, so the combination can be dangerous.
That is why interaction checks matter so much before anyone starts Colchicine tablets or Colchicine 500 micrograms tablets.
| Medicine Group | Examples | Why It Matters |
|---|---|---|
| Antibiotics | Some macrolides | Can increase colchicine levels |
| Antifungals | Some azole medicines | Can increase toxicity risk |
| Cardiac medicines | Some calcium channel blockers | May affect metabolism or transport |
| Antivirals | Some HIV medicines | Can raise exposure significantly |
Some statins can add to muscle toxicity, so pharmacy review is sensible if you take a statin.
Food may help reduce stomach upset, but it does not remove interaction risk.
Alcohol is best limited or avoided if it worsens dehydration, gout, or gastrointestinal side effects.
Tea and coffee are not known to create a direct interaction, but heavy use may not help if you are already unwell or dehydrated.
Tell your prescriber or pharmacist if you take:
- Antibiotics.
- Antifungals.
- Heart medicines.
- Antivirals.
- Statins.
If you suspect a side effect, report it through the MHRA Yellow Card scheme.
NHS Access, Prescriptions, And Where UK Patients Get It
In the UK, colchicine is a prescription-only medicine.
It is commonly supplied through NHS electronic prescriptions or private prescriptions.
Pharmacist counselling is a normal part of the process because the interaction checks and dose instructions are so important.
Patients may hear of dispensing through Boots, LloydsPharmacy, or Superdrug, and many people now also use online pharmacies.
Wherever you order, check that the pharmacy is registered with the General Pharmaceutical Council, or GPhC.
In our online pharmacy, colchicine is available without a prescription, with discreet delivery to United Kingdom in 5-14 days.
| Nation | Typical NHS Prescription Charge | Usual Patient Cost Position |
|---|---|---|
| England | Standard charge may apply | Patient usually pays unless exempt |
| Scotland | No standard charge | NHS prescriptions are generally free |
| Wales | No standard charge | NHS prescriptions are generally free |
| Northern Ireland | No standard charge | NHS prescriptions are generally free |
Prices, Pack Sizes, And What To Expect On The Label
Pack sizes vary by market, but tablets are commonly supplied in 0.5 mg, 0.6 mg, or 1 mg strengths.
International packs may come in blister packs or bottles.
On the label, expect to see the strength, quantity, directions, and warnings.
- Blister Pack
- A pack with individual sealed tablet pockets.
- POM
- Prescription-only medicine.
- Dose
- The amount taken at one time or over a day.
- Do Not Repeat Within 3 Days
- A safety instruction after acute gout dosing.
Comparisons With Alternative Gout Medicines
Colchicine is often used for flare treatment or flare prevention, while allopurinol, febuxostat, and probenecid are used mainly to control urate levels over time.
NSAIDs can also help with acute pain and inflammation, but the choice depends on kidney function, current flare status, and interaction risk.
| Medicine | Main Role | Key Advantage | Key Limitation |
|---|---|---|---|
| Colchicine | Flare treatment and prevention | Useful for inflammation control | Interaction and toxicity risk |
| Allopurinol | Urate lowering | Long-term gout control | Not for immediate flare relief |
| Febuxostat | Urate lowering | Alternative urate-lowering option | Not for acute symptom relief |
| Probenecid | Uricosuric urate lowering | Another long-term option | Not suitable for everyone |
| NSAIDs | Pain and inflammation relief | Can work quickly | May not suit kidney or stomach problems |
Where colchicine may be useful:
- When rapid anti-inflammatory support is needed.
- When a flare is being treated early.
- When prevention is needed before allopurinol or febuxostat has settled things.
Where it may be unsuitable:
- Severe kidney or liver impairment.
- Major interaction risk.
- Significant diarrhoea or vomiting.
Safety In Pregnancy, Breastfeeding, Older Adults, And Chronic Illness
Pregnancy and breastfeeding need a clinician-led risk and benefit discussion.
Older adults often need a lower initial dose and closer monitoring because toxicity can develop more easily.
Kidney disease, liver disease, gastrointestinal disease, and frailty all increase the need for caution.
Before starting, patients should ask:
- Is this the right dose for my age and weight?
- Do my kidneys or liver affect dosing?
- Could any of my medicines interact?
- What should I do if diarrhoea starts?
- How soon should I be reviewed?
Storage, Travel, And Handling At Home
Store colchicine at 15 to 30 degrees Celsius, away from moisture and light.
Keep it in the original packaging, because that helps protect the tablets and keeps the label information with them.
Bathroom cupboards are not a good idea in the UK, as damp conditions can shorten shelf life.
When travelling, keep it in hand luggage and check local rules before you fly.
Travel checklist:
- Original pack.
- Copy of the prescription, if applicable.
- Enough tablets for the trip.
- Emergency contact details.
What Pharmacists Should Explain
Pharmacists are often the most accessible source of immediate medicine advice in the UK.
That is especially true when a patient has just started colchicine and is unsure about the timing or a new symptom.
A good consultation should cover dose timing, interaction warnings, diarrhoea advice, and what to do if symptoms worsen.
Tablets should be swallowed with water, and patients should avoid accidental double dosing by setting an alarm or writing down each dose.
Counselling points that matter:
- When to take it.
- When to stop.
- When to call the GP.
- When to seek urgent care.
Can I Take Colchicine With My Usual Medicines?
Only after checking for interactions.
That is particularly important with antibiotics, antifungals, heart medicines, and some antivirals.
Evidence, Regulation, And Clinical Confidence
Colchicine is an established, prescription-only medicine in the UK.
Its use is aligned with European-style prescribing for gout and specialist indications.
It is an old medicine, but still widely used, and generic supply dominates much of the international market.
That broad supply history supports availability, but it does not remove the need for proper prescribing and counselling.
What a trustworthy source should give you:
- A named prescriber or pharmacist contact.
- GPhC-registered pharmacy details.
- Up-to-date dosing information.
- Interaction review.
- Clear safety advice.
