Why Did My Gout Medication Make My Gout Worse?

Understanding a common perception about gout treatment

Many people assume that once they start medication to lower their uric acid, their gout attacks should immediately improve.

Surprisingly, the opposite can sometimes happen.

As a rheumatologist, one of the common questions I hear is:

"Doctor, ever since I started my gout medication, my gout has become worse. Should I stop it?"

The answer is often no — and understanding why can prevent unnecessary suffering.

A real patient story

A 34-year-old gentleman came to my clinic barely able to walk.

His right big toe was swollen, red, and so painful that even the lightest pressure caused severe discomfort.

During the previous year, he had experienced four gout attacks affecting his big toes and occasionally his knees. Blood tests consistently showed an elevated uric acid level of around 9 mg/dL, confirming the diagnosis.

One week before seeing me, he developed another attack.

His physician prescribed an anti-inflammatory medication and started a uric acid-lowering medication to help prevent future gout attacks.

Everything seemed appropriate. But only four days later, he stopped taking the medication.

"The medicine made my gout worse," he told me. Interestingly… he was right.

Why can gout get worse after starting treatment?

This is one of the biggest paradoxes in gout treatment.

Imagine that uric acid crystals are like tiny shards of glass that have quietly accumulated inside your joints over many years. Your body gradually becomes accustomed to these crystal deposits.

When urate-lowering therapy begins reducing the serum urate level, those existing deposits are mobilised. As they dissolve and shift, the immune system recognises them again and an inflammatory response follows. This is why starting or increasing urate-lowering therapy can temporarily increase the risk of a flare.¹

The medicine is not creating more gout. A flare after starting treatment does not necessarily mean the medication is ineffective or harmful — it is a recognised, usually temporary effect of changing the urate level.

It also helps to know that urate-lowering therapy is long-term preventive treatment. It does not provide immediate pain relief during an acute flare; the flare itself is treated separately with anti-inflammatory treatment prescribed by your doctor.

The important principle: treat the attack first

When my patient came to see me he had already stopped the medication himself, and his joint was still severely inflamed. We first focused on controlling the inflammation. (Note that in someone already established on urate-lowering therapy, the medicine is usually continued through a flare rather than stopped.¹,²)

He received a flare-prevention medication and an anti-inflammatory medication.

Over the next several days, the swelling subsided, the redness faded, and the pain gradually disappeared. Only after the attack had completely resolved did we restart the uric acid-lowering medication.

Preventing future gout attacks

This time we used a different strategy. Alongside the urate-lowering medication we continued low-dose anti-inflammatory prophylaxis.

Anti-inflammatory prophylaxis may be offered when urate-lowering therapy is started or the dose is increased, depending on the individual's clinical circumstances, other medicines and contraindications.¹,² There is no single fixed duration that applies to everyone; how long it is continued is a prescribing decision reviewed over time.

Allopurinol is commonly started at a low dose and titrated upwards while monitoring serum urate and clinical factors. The appropriate starting dose and titration depend on kidney function and other individual factors, so no universal dose applies.¹,²

Over the following months his uric acid dropped from 9 mg/dL, then 7, then 6, then 5, eventually reaching 4 mg/dL. As the uric acid reached the target level, the gout attacks stopped.

The flare-prevention medication was eventually discontinued. The uric acid-lowering medication was continued. He has remained free of gout attacks.

The most important lesson

Many patients judge a treatment by what happens during the first few days. Doctors judge a treatment by where it leads over months and years.

Lowering uric acid is the only way to prevent gout from returning. The attack itself is only the visible part of the disease. The real problem is the silent accumulation of uric acid crystals inside the joints over time.

Without treating that underlying problem, attacks almost always return.

Key take-home messages

• Do not start, stop or change any prescription medicine on your own. Changes to urate-lowering therapy should be made by your prescriber.
• Urate-lowering therapy is usually continued during a flare rather than stopped abruptly, unless your prescriber identifies a separate safety concern.¹,²
• Anti-inflammatory prophylaxis may be offered when urate-lowering therapy is started or titrated, according to your clinical circumstances and any contraindications.¹,²
• Guidelines recommend a treat-to-target strategy, commonly aiming below 6 mg/dL (360 μmol/L), with a lower target considered in selected people with more severe disease.¹,²

When should you see a rheumatologist?

If you have recurrent gout attacks, high uric acid levels, kidney stones, lumps under the skin (tophi), or persistent joint pain despite treatment, you may benefit from a comprehensive assessment and a long-term treatment plan designed to prevent future attacks and protect your joints.

Frequently Asked Questions

Why did my gout get worse after starting uric-acid-lowering treatment?

Changing the serum urate level mobilises crystals already deposited in the joints, which can trigger flares in the first weeks or months. This is recognised, does not mean the medication is failing or harmful, and the risk can be reduced with low-dose titration and anti-inflammatory prophylaxis where appropriate.¹

Should I stop my uric acid medication during a flare?

Urate-lowering therapy is commonly continued during a flare rather than stopped abruptly, unless your prescriber identifies a separate safety concern. The flare itself is treated with anti-inflammatory treatment. Do not change any prescription medicine without speaking to your doctor.¹,²

Should I take something to prevent flares when starting uric acid-lowering medication?

Often, yes. Anti-inflammatory prophylaxis may be offered when urate-lowering therapy is started or titrated, depending on your clinical circumstances, other medicines and any contraindications. How long it is continued varies between people.¹,²

What uric acid level should I actually be aiming for?

Guidelines recommend a treat-to-target strategy, commonly aiming below 6 mg/dL (360 μmol/L), with a lower target considered in selected people with more severe disease.¹,²

Can this reaction be avoided entirely before starting treatment?

Not entirely, because mobilising existing crystal deposits is part of how the treatment works. The risk can be reduced with low-dose starting and titration and, where appropriate, anti-inflammatory prophylaxis planned from the outset — which is why treatment is best started and adjusted under medical supervision rather than changed independently.¹

How soon can I expect fewer gout attacks after starting treatment?

Flares commonly become less frequent once serum urate is held at target, and deposits continue to dissolve over a longer period. Timelines vary between individuals, and no treatment can guarantee that you will never have another attack.

Final thoughts

Gout is often thought of as one of the simpler forms of arthritis, but successful treatment requires understanding its unique behavior.

Sometimes the road to recovery briefly passes through worsening symptoms.

The medication wasn't the problem. The timing was.
