In short
A raised uric acid level found on a routine panel, in someone who has never had an attack, is usually not treated with medicine. Once gout has caused repeated attacks, a tophus, a kidney stone or joint damage, the picture reverses completely: medicine is the treatment, the dose is adjusted to a target level, and it is taken for life.
Two people arrive with the same number on a report. One has never had a painful joint in his life and the uric acid was found on a corporate health check. The other has had four attacks in two years and a lump on his ear.
They need completely different things, and the number does not distinguish them. What distinguishes them is what the urate has already done.
A high level with no symptoms is usually left alone
A raised uric acid level without gout has a name — asymptomatic hyperuricaemia — and it is common. Most people who have it never develop gout.
Major rheumatology guidelines do not recommend urate-lowering medicine for a raised level alone. The reasoning is straightforward: the medicine would be taken for decades to prevent something that, for most of those people, was never going to happen, and every medicine has a cost.
What is worth doing instead is looking for the reasons the level is high, because several of them matter in their own right:
- Medicines. Diuretics for blood pressure, low-dose aspirin and ciclosporin all raise urate. A change of blood pressure tablet sometimes solves the problem entirely, and losartan happens to lower urate slightly.
- Kidney function. Most urate is cleared by the kidneys. A raised level can be the first sign that clearance has fallen.
- Metabolic health. High urate travels with obesity, fatty liver, high blood pressure, insulin resistance and raised triglycerides. These deserve attention whether or not the urate is ever treated.
- Alcohol and fructose. Beer and spirits, and sweetened drinks, raise urate reliably.
The exception worth knowing: a very high level — generally quoted above about 9 mg/dL — in someone with kidney stones or a family history of early gout is sometimes treated after discussion. That is a judgement, not a rule.
Who does need treatment
The decision follows what has happened, not what the level is. Urate-lowering treatment is recommended when any of these is true:
- Two or more attacks in a year. The single commonest reason.
- A tophus — a firm, chalky deposit under the skin, often on the ear, the elbow, a finger or the Achilles tendon.
- Joint damage on X-ray attributable to gout.
- Kidney stones made of urate.
- Gout with chronic kidney disease, where the margin for repeated attacks and repeated anti-inflammatories is much smaller.
Many rheumatologists will also offer it after a first attack when the person is young, the level is very high, or there is kidney disease — because the alternative is waiting for the disease to prove itself at the patient's expense.
The target, and why the dose keeps changing
This is the part most often missed, and it is the part that decides whether treatment works.
Urate-lowering treatment is not a fixed dose of a tablet. It is a target. The level has to come down below the point at which urate crystallises, and stay there, so that the deposits already in the joints dissolve.
The widely used target is below 6 mg/dL, and below 5 mg/dL where there are tophi, because deposits dissolve faster at lower levels. Treatment starts at a low dose, the level is rechecked after a few weeks, and the dose is increased until the target is reached. That is called treat-to-target, and it is the difference between a medicine that works and a medicine that is merely taken.
The common failure is starting allopurinol 100 mg, never rechecking, and concluding years later that allopurinol does not work. It almost always works. It was under-dosed.
Attacks when treatment begins are expected
For the first few months after urate-lowering treatment starts, attacks can become more frequent. This is not failure. As the level falls, the deposits that have been sitting quietly begin to break up, and the body reacts to them.
Because of this, a preventive medicine — usually low-dose colchicine, sometimes a low-dose NSAID — is given alongside for the first three to six months. How colchicine is used covers that in detail.
Two rules follow from this, and they are the most important sentences in this article:
- Do not stop urate-lowering medicine because you have an attack.
- Do not start it in the middle of one.
What to do in the first 24 hours of an attack covers the acute end.
Which medicine
Allopurinol is first choice almost everywhere. It is cheap, very well understood, and effective when the dose is pushed to target. It is started low and increased, which also reduces the small risk of a serious rash.
Febuxostat is the main alternative, used when allopurinol is not tolerated or cannot reach target. It works through the same pathway and does not need the same dose reduction in mild kidney impairment. How that choice is actually made sets out the considerations, including the cardiovascular question.
In either case the pattern is the same: start low, check the level, increase, check again.
How long for
For life, in most people.
This is the part patients are least often told, and the omission causes real harm. Gout is a deposit disease. Lowering urate dissolves the deposits over months to years; stopping lets the level climb back and the deposits re-form. People who stop after a good year are usually back within two.
There is a conversation to be had, after several years at target with no attacks and no tophi, about whether a lower maintenance dose is enough. That is a conversation, not a reason to stop on your own.
What about diet instead?
Diet matters and it is not a substitute. Strict dietary change typically lowers urate by around 1 mg/dL — useful, often not enough on its own to get from 9 to under 6.
Where diet earns its place is in removing triggers and in the metabolic problems that travel with gout. A gout diet that works with an Indian kitchen is about doing that without turning every meal into a calculation.
What a tophus is, and why it changes the decision
A tophus is a lump of urate crystals that has built up in or near a joint, under the skin. They are firm, often yellowish-white under thin skin, and usually painless — which is why people live with them for years without mentioning them.
Common sites: the outer edge of the ear, the elbow, the fingers, the Achilles tendon and around the toes.
A tophus means the deposits have been accumulating for a long time, and it changes the decision in two ways. It is an unambiguous indication to start urate-lowering treatment, and it lowers the target — below 5 mg/dL rather than 6 — because deposits dissolve faster at lower levels.
The good news is that tophi do shrink and eventually disappear on properly dosed treatment. It takes months to years, and it does happen. If you have a firm lump on an ear or elbow and a history of joint attacks, show it to your doctor.
Monitoring
Once established, monitoring is light: the urate level and kidney function periodically, more often while the dose is being adjusted. What the uric acid number actually means explains how to read it.
If you have had more than one attack and nobody has set a target level for you, that is the gap worth closing. You can request a callback or book an appointment.
Common questions
My uric acid is 8 but I have no pain. Do I need medicine?
Usually not. A raised level with no attacks, no tophi and no urate kidney stones is not normally treated with urate-lowering medicine. What is worth doing is checking kidney function, reviewing medicines such as diuretics and low-dose aspirin that raise urate, and addressing weight, alcohol and sweetened drinks.
What uric acid level should I aim for on treatment?
Below 6 mg/dL is the usual target, and below 5 mg/dL where there are tophi, because deposits dissolve faster at lower levels. The dose is increased until that target is reached rather than left at the starting dose.
Can I stop allopurinol once my uric acid is normal?
The level is normal because of the medicine. Stopping allows it to rise again and the deposits to re-form, and attacks usually return within a year or two. Treatment is generally lifelong, though the dose can sometimes be reviewed after several stable years.
Why did my attacks get worse after starting treatment?
This is expected in the first months. A falling urate level disturbs crystal deposits that were sitting quietly, and the body reacts to them. A preventive medicine is normally given alongside for three to six months for this reason. It is a sign the deposits are dissolving, not that the medicine is wrong.
Can diet alone bring uric acid down enough?
Strict dietary change lowers urate by roughly 1 mg/dL. That helps, and it is often not enough on its own when the level needs to fall from 9 to below 6. Diet is most valuable for removing triggers and for the weight, blood pressure and liver problems that commonly accompany gout.
