Gout: Why Treating Each Attack Never Ends It, and the Uric Acid Target That Stops Them Completely

Here is the pattern that costs people their joints.

An attack arrives. It is agonising for a few days, treated with an anti-inflammatory, and gone within two weeks. Six months later another one. Then another. Each is survivable, each gets treated, and everyone involved calls that managing the gout.

Meanwhile the crystals that caused the first attack have never left, and more are forming every month. After ten or fifteen years of this there are visible lumps, permanent joint damage and X-ray erosions — from a condition that is one of the very few in medicine that can be switched off completely.

📊 Why a normal result is not good enough

This is the single most useful thing on this page, and it catches patients and doctors alike.

Laboratory reference ranges for uric acid usually run up to about 420 micromol per litre, or 7 mg/dL. So a result of 400 comes back flagged as normal.

But the reference range describes what is common in the population, not what is safe for someone with gout. Crystals form above roughly 360 and dissolve below it. A patient told their uric acid is normal at 400 is being told the wrong thing: that level will keep producing attacks indefinitely.

So the question to ask is not is my uric acid normal. It is what is my number, and is it under 360.

One more thing that misleads in the other direction: uric acid often falls during an acute attack, sometimes into the normal range. A normal reading taken while the joint is hot proves nothing. It is measured again a few weeks after things settle.

🔥 The attack itself

Gout announces itself distinctively, which is why it is usually diagnosed on the history.

• 🕒 Onset over a few hours, very often waking the person in the early morning
• 🦶 Base of the big toe in more than half of first attacks. Then instep, ankle, knee; later elbows, wrists and fingers
• 🔴 Red, hot, shiny, swollen — and painful enough that the weight of a bedsheet is unbearable
• 📈 Peaks within 12 to 24 hours and settles over one to two weeks even if nothing is done
• 🌀 Usually one joint at first; multiple joints become more common after years

💊 Treating the attack

Speed matters: starting within the first 24 hours shortens it considerably. Any one of three approaches works, and the choice depends on what else you have.

Alongside the tablet: rest the joint, keep it elevated, apply ice, and keep fluids up.

💎 Allopurinol: the schedule that works

Zyloprim (Allopurinol) blocks the enzyme that produces uric acid. It does nothing for an attack in progress and everything for the condition.

That third row is where most treatment fails. Allopurinol is routinely left at 100 or 300 mg and never checked against a blood test, the attacks continue, and the drug gets labelled ineffective. It was not ineffective; it was under-dosed. If you have been on the same dose for years and still get attacks, the question is what your current uric acid level is.

⚠️ Allopurinol safety: one rash and one interaction

And one interaction that is potentially fatal: allopurinol blocks the breakdown of azathioprine and mercaptopurine, causing those drugs to accumulate and shut down the bone marrow. Anyone on either of them — usually for inflammatory bowel disease, transplant or autoimmune conditions — must not be given allopurinol without specialist supervision and a drastically reduced dose.

The rest, briefly: warfarin and theophylline levels can rise; nausea and headache occur early and usually settle; and monitoring during titration covers uric acid, kidney function, liver enzymes and a blood count.

💊 The medicines that cause gout, and the two that help

This is the quickest win available and it is checked far too rarely.

Raise uric acid:

• 💧 Thiazide and loop diuretics — much the commonest culprit. Someone on a water tablet for blood pressure who develops gout has a likely cause sitting in the dosette box
• 💊 Low-dose aspirin — taken by huge numbers of people for the heart, and rarely connected
• 🧪 Ciclosporin and tacrolimus

Lower uric acid:

• ✅ Losartan, among the blood pressure drugs, has a mild urate-lowering effect
• ✅ Amlodipine likewise, and atorvastatin and fenofibrate modestly

So for a person with both high blood pressure and gout, swapping a thiazide for losartan or amlodipine treats both problems with one change. That conversation is worth having explicitly, and it does not happen unless the patient raises it. Nobody should stop a blood pressure tablet on their own — but asking whether the choice could be reconsidered is entirely reasonable.

🍺 Diet: what it does and what it cannot do

Here is the honest arithmetic that most gout advice avoids. Dietary change lowers uric acid by roughly 10 to 15 percent. For someone at 480 that brings them to around 420 — a real improvement, and still above the threshold where crystals form.

So diet helps and diet alone will not get most people to target. Anyone told to sort their eating out instead of being offered treatment has been given advice that cannot work.

That said, the specific items do matter, and the list is narrower than the folklore:

Weight loss does lower urate meaningfully, and it should be gradual — rapid loss and fasting push it up in the short term.

❤️ Gout is not only a joint problem

Worth knowing because it changes what else should be checked.

Gout travels with high blood pressure, chronic kidney disease, obesity, type 2 diabetes and cardiovascular disease, and the association is strong enough that a new diagnosis of gout is a reasonable prompt to look at all of them. The kidney link runs both ways: reduced kidney function raises urate, and prolonged high urate is associated with declining kidney function.

So at diagnosis it is worth having blood pressure, kidney function, glucose or HbA1c, and a lipid profile checked. Our guides to blood pressure, cholesterol and type 2 diabetes cover those.

🦴 What untreated gout eventually does

The reason any of this matters, stated plainly.

Crystals that keep accumulating form tophi — firm, chalky lumps under the skin, classically over the elbows, the backs of the fingers, the Achilles tendon and the rim of the ear. They can ulcerate and discharge white material, and they are visible, which many people find harder than the pain.

Underneath, the crystals erode bone. Joint damage from long-standing gout is permanent, and by the time it shows on an X-ray it cannot be reversed. Attacks also become more frequent, longer, and spread to more joints.

All of which is avoidable with one tablet taken to a target. And tophi dissolve once the level is held low enough, over months to a few years, which is the main argument for aiming under 300 rather than 360 when they are present.

📈 How to tell it is working

• 📊 The number is the measure. Under 360 is the goal, and it is the only reliable sign in the first months
• 📉 Attacks increase first, then stop. Expect flares during the first three to six months, then a steady decline. By twelve months most people have none
• 🦴 Tophi soften and shrink over one to several years
• 🚫 What is not a sign: feeling fine. Urate is invisible, and someone who stops the tablet because they have had no attacks for a year will have attacks again

🔎 When it is not gout

Four conditions are mistaken for it, and one of them is an emergency.

• 🚨 Septic arthritis — hot swollen joint with fever or feeling unwell. Same-day emergency, as above
• 🦴 Pseudogout — a different crystal, usually in the knee or wrist rather than the toe, more often in older people. Looks similar, and allopurinol does nothing for it
• 🟥 Cellulitis — skin infection, where the redness spreads beyond the joint and the joint itself moves reasonably
• 📍 Psoriatic arthritis — particularly when fingers or toes are involved and there is psoriasis or nail pitting. See our guide to telling joint conditions apart

Where there is genuine doubt, examining fluid drawn from the joint settles it definitively — crystals under a microscope, or bacteria.

📞 When to seek help

Promptly:

• A second attack — that is the point at which urate-lowering treatment should be discussed, not after the tenth
• Taking allopurinol and still getting attacks — ask what your current uric acid level is, and whether the dose should go up
• Never having had the level measured, or having been told it is normal without being given the number
• On a thiazide diuretic or low-dose aspirin with gout — ask whether the blood pressure drug could be switched
• Taking azathioprine or mercaptopurine — before allopurinol is started, without exception
• Lumps appearing over elbows, fingers, the Achilles tendon or the ear
• Reduced kidney function — it changes the starting dose and raises the hypersensitivity risk
• Attacks in several joints at once, or lasting beyond two weeks
• A new diagnosis of gout — ask for blood pressure, kidney function, glucose and lipids at the same time
